phpinfo

(PHP 4, PHP 5)

phpinfoMostra muitas informações sobre o PHP

Descrição

int phpinfo ([ int $what ] )

Mostra uma grande quantidade de informações sobre o estado atual do PHP. Isto inclui informações sobre as opções de compilação do PHP e extensões, a versão do PHP, informações do servidor e ambiente (se compilado como um módulo), o ambiente PHP, informação da versão do SO, caminhos, valores principais e locais das opções de configuração, cabeçalhos HTTP e a licença do PHP.

Devido a configuração em cada sistema ser diferente, a função phpinfo() e normalmente utilizada para conhecer as definições de configuração e as variáveis pré-definidas que estejam disponíveis no sistema. phpinfo() é também é uma ferramenta valiosa para eliminação de erros já que contém todos os dados de EGPCS (Environment, GET, POST, Cookie, Server).

A saída pode ser configurada passando-se uma ou mais das seguintes constants que serão somadas junto com o parâmetro opcional what . Pode combinar as respectivas constantes ou seus valores bit a bit juntos com o operador or.

Opções phpinfo()
Nome (constant) Valor Descrição
INFO_GENERAL 1 A linha de configuração, localização do php.ini data de construção, Servidor Web, Sistema e mais.
INFO_CREDITS 2 Créditos do PHP 4. Veja também phpcredits().
INFO_CONFIGURATION 4 Valores locais e principais para as diretivas de configuração do PHP. Veja também ini_get().
INFO_MODULES 8 Módulos carregados e suas respectivas configurações. Veja também get_loaded_modules().
INFO_ENVIRONMENT 16 Informação das variáveis de ambiente que também esta disponível em $_ENV.
INFO_VARIABLES 32 Mostra todas as variáveis pré-definidas de EGPCS (Environment, GET, POST, Cookie, Server).
INFO_LICENSE 64 Informação sobre a Licença do PHP. Veja também o » faq sobre a licença.
INFO_ALL -1 Mostra tudo acima. Este é o valor padrão.

Exemplo #1 Exemplos phpinfo()

<?php

// Mostra todas as informações, usa o padrão INFO_ALL
phpinfo();

// Mostra apenas informações dos módulos.
// phpinfo(8) mostra um resultado identico.
phpinfo(INFO_MODULES);

?>

Nota: Partes da informação mostrada é desabilitada quando a diretiva de configuração expose_php for definida para off. Isto inclui os logos do PHP e Zend, e os créditos.

Nota: phpinfo() envia texto simples ao invés de HTML quando esta usando o modo CLI.

Veja também phpversion(), phpcredits(), php_logo_guid(), ini_get(), ini_set(), get_loaded_modules(), e a seção sobre Variáveis Pré-definidas.

I wanted a simple *function* to convert the output of phpinfo into an array.  Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c

Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.

== Sample Output ==
[PHP Configuration] => Array
 (
  [PHP Version] => 5.2.6
  [PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42
  [System] => Linux askapache 2.6.22.19-grsec3
  [Build Date] => Nov 11 2008 13:09:07
  [Configure Command] =>  ./configure --prefix=/home/grsec/bin/php
  [Server API] => FastCGI

  [IPv6 Support] => enabled
 [Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42
  [PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
 )

[mbstring] => Array
 (
  [mbstring.http_input] => pass
  [mbstring.internal_encoding] => Array
    (
     [0] => ISO-8859-1
     [1] => no value
    )

  [mbstring.language] => neutral
   )

[mcrypt] => Array
 (
  [Version] => 3.5.7
  [Api No] => 20031217
 )

<?php
function phpinfo_array($return=false){
 
/* Andale!  Andale!  Yee-Hah! */
 
ob_start();
 
phpinfo(-1);
 
 
$pi = preg_replace(
 array(

'<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),
 
ob_get_clean());

 
$sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));
 unset(
$sections[0]);

 
$pi = array();
 foreach(
$sections as $section){
  
$n = substr($section, 0, strpos($section, '</h2>'));
  
preg_match_all(
  
'#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',
    
$section, $askapache, PREG_SET_ORDER);
   foreach(
$askapache as $m)
      
$pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
 }

 return (
$return === false) ? print_r($pi) : $pi;
}

A simple method to style your own phpinfo() output.

<style type="text/css">
#phpinfo {}
#phpinfo pre {}
#phpinfo a:link {}
#phpinfo a:hover {}
#phpinfo table {}
#phpinfo .center {}
#phpinfo .center table {}
#phpinfo .center th {}
#phpinfo td, th {}
#phpinfo h1 {}
#phpinfo h2 {}
#phpinfo .p {}
#phpinfo .e {}
#phpinfo .h {}
#phpinfo .v {}
#phpinfo .vr {}
#phpinfo img {}
#phpinfo hr {}
</style>

<div id="phpinfo">
<?php

ob_start
() ;
phpinfo () ;
$pinfo = ob_get_contents () ;
ob_end_clean () ;

// the name attribute "module_Zend Optimizer" of an anker-tag is not xhtml valide, so replace it with "module_Zend_Optimizer"
echo ( str_replace ( "module_Zend Optimizer", "module_Zend_Optimizer", preg_replace ( '%^.*<body>(.*)</body>.*$%ms', '$1', $pinfo ) ) ) ;

?>
</div>

My hosting company doesn't let me edit my php.ini file, but I wanted most of the same values, so I adapted one of the above posts to let me convert the information from phpinfo into a page where so can just copy and paste the info into a new php.ini file.

<?php
ob_start
();
phpinfo(INFO_CONFIGURATION);
$phpinfo = array('phpinfo' => array());
if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
    foreach(
$matches as $match)
        if(
strlen($match[1]))
           
$phpinfo[$match[1]] = array();
        elseif(isset(
$match[3]))
           
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        else
           
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>

<?php
   
foreach($phpinfo as $name => $section) {
         foreach(
$section as $key => $val) {
            if(
is_array($val))
                echo
"$key = $val[0]<br>";
            elseif(
is_string($key))
                echo
"$key = $val<br>";
            else
                echo
"$val<br>";
        }
        echo
"\n";
    }
?>

To extract all of the data from phpinfo into a nested array:
<?php
ob_start
();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(
preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
    foreach(
$matches as $match)
        if(
strlen($match[1]))
           
$phpinfo[$match[1]] = array();
        elseif(isset(
$match[3]))
           
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        else
           
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>

Some examples of using individual values from the array:

<?php
   
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
    echo
"Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
    echo
"License: {$phpinfo['PHP License'][0]}<br />\n";
?>

To display everything:

<?php
   
foreach($phpinfo as $name => $section) {
        echo
"<h3>$name</h3>\n<table>\n";
        foreach(
$section as $key => $val) {
            if(
is_array($val))
                echo
"<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
            elseif(
is_string($key))
                echo
"<tr><td>$key</td><td>$val</td></tr>\n";
            else
                echo
"<tr><td>$val</td></tr>\n";
        }
        echo
"</table>\n";
    }
?>

Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!

some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)

we need to change two lines:

<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match
('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>

and

<?php
preg_split
( '/\n/', $matches[1] )
?>
to
<?php
preg_split
( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>

That's all! Now we have a really flexible addition to phpinfo();

Embedding phpinfo within your page, that already has style information:

The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.

Yes, we cheat on preparing the selector list.

<?php
ob_start
();
phpinfo();

preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);

# $matches [1]; # Style information
# $matches [2]; # Body information

echo "<div class='phpinfodisplay'><style type='text/css'>\n",
   
join( "\n",
       
array_map(
           
create_function(
               
'$i',
               
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
               
),
           
preg_split( '/\n/', $matches[1] )
            )
        ),
   
"</style>\n",
   
$matches[2],
   
"\n</div>\n";
?>

Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.

I have changed the preg_match_all() here so that the last <td></td> is optional

<?php
function parsePHPConfig() {
   
ob_start();
   
phpinfo(-1);
   
$s = ob_get_contents();
   
ob_end_clean();
   
$a = $mtc = array();
    if (
preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
        foreach(
$mtc as $v){
            if(
$v[2] == '<i>no value</i>') continue;
           
$a[$v[1]] = $v[2];
        }
    }
    return
$a;
}
?>

Here's a variant of "print it without headers, but include the style information":

<?php
ob_start
();
phpinfo();
$info = ob_get_clean ();

$matches = array ();
$i = preg_match ('%(<style type="text/css">.*</style>).*<body>(.*)</body>%s', $info, $matches);

print
$matches [1]; # Style information
print $matches [2]; # Body

same as above for configuration variables

<?php
function parsePHPConfig() {
   
ob_start();
   
phpinfo(INFO_CONFIGURATION);
   
$s = ob_get_contents();
   
ob_end_clean();
   
$a = $mtc = array();
    if (
preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td><td class="v">(.*?)<\/td><\/tr>/',$s,$mtc,PREG_SET_ORDER)) {
        foreach(
$mtc as $v){
            if(
$v[2] == '<i>no value</i>') continue;
           
$a[$v[1]] = $v[2];
        }
    }
    return
$a;
}

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:

<?php

/* parse php modules from phpinfo */

function parsePHPModules() {
 
ob_start();
 
phpinfo(INFO_MODULES);
 
$s = ob_get_contents();
 
ob_end_clean();

 
$s = strip_tags($s,'<h2><th><td>');
 
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
 
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
 
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
 
$vModules = array();
 for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
  
$vPat = '<info>([^<]+)<\/info>';
  
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
  
$vPat2 = "/$vPat\s*$vPat/";
   if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
   } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
   }
   }
  }
 }
 return
$vModules;
}
?>

To obtain a phpinfo without headers (and css) :

<?php
ob_start
();                                                                                                       
phpinfo();                                                                                                        
$info = ob_get_contents();                                                                                        
ob_end_clean();                                                                                                   

$info = preg_replace('%^.*<body>(.*)</body>.*$%ms', '$1', $info);
?>

You can then style your tables & headings :)

This function parses the phpinfo output to get details about a PHP module.

<?php
/** parse php modules from phpinfo */
function parsePHPModules() {
 
ob_start();
 
phpinfo(INFO_MODULES);
 
$s = ob_get_contents();
 
ob_end_clean();
 
 
$s = strip_tags($s,'<h2><th><td>');
 
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
 
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
 
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
 
$vModules = array();
 for (
$i=1;$i<count($vTmp);$i++) {
  if (
preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
  
$vName = trim($vMat[1]);
  
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach (
$vTmp2 AS $vOne) {
   
$vPat = '<info>([^<]+)<\/info>';
   
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
   
$vPat2 = "/$vPat\s*$vPat/";
    if (
preg_match($vPat3,$vOne,$vMat)) { // 3cols
    
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
    } elseif (
preg_match($vPat2,$vOne,$vMat)) { // 2cols
    
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
    }
   }
  }
 }
 return
$vModules;
}
?>

Sample Output:
[gd] => Array
(
  [GD Support] => enabled
  [GD Version] => bundled (2.0.28 compatible)
  [FreeType Support] => enabled
  [FreeType Linkage] => with freetype
  [FreeType Version] => 2.1.9
  [T1Lib Support] => enabled
  [GIF Read Support] => enabled
  [GIF Create Support] => enabled
  [JPG Support] => enabled
  [PNG Support] => enabled
  [WBMP Support] => enabled
  [XBM Support] => enabled
)

[date] => Array (
  [date/time support] => enabled
  [Timezone Database Version] => 2005.14
  [Timezone Database] => internal
  [Default timezone] => America/Los_Angeles
  [Directive] => Array (
     [0] => Local Value
     [1] => Master Value
  )
  [date.timezone] => Array (
     [0] => no value
     [1] => no value
  )
 )


<?php
/** get a module setting */
function getModuleSetting($pModuleName,$pSetting) {
 
$vModules = parsePHPModules();
 return
$vModules[$pModuleName][$pSetting];
}
?>

Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

check out this cool and fantastic colourful phpinfo()!

<?php

ob_start
();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();

preg_match_all('/#[0-9a-fA-F]{6}/', $phpinfo, $rawmatches);
for (
$i = 0; $i < count($rawmatches[0]); $i++)
  
$matches[] = $rawmatches[0][$i];
$matches = array_unique($matches);

$hexvalue = '0123456789abcdef';

$j = 0;
foreach (
$matches as $match)
{

  
$r = '#';
  
$searches[$j] = $match;
   for (
$i = 0; $i < 6; $i++)
     
$r .= substr($hexvalue, mt_rand(0, 15), 1);
  
$replacements[$j++] = $r;
   unset(
$r);
}

for (
$i = 0; $i < count($searches); $i++)
  
$phpinfo = str_replace($searches, $replacements, $phpinfo);
echo
$phpinfo;
