php

To obtain a phpinfo without headers (and css) : <? 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 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; } ?>

This function parses the phpinfo output to get details about a PHP module. /** 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 $vModules; } Sample Output: [gd] => Array ( [GD Support] => enabled [GD Version] => bundled (2.0.28 compatible) [FreeType Support] => enabled [FreeType Linkage] => with freetype [FreeType Version] => 2.1.9 [T1Lib Support] => enabled [GIF Read Support] => enabled [GIF Create Support] => enabled [JPG Support] => enabled [PNG Support] => enabled [WBMP Support] => enabled [XBM Support] => enabled ) [date] => Array ( [date/time support] => enabled [Timezone Database Version] => 2005.14 [Timezone Database] => internal [Default timezone] => America/Los_Angeles [Directive] => Array ( [0] => Local Value [1] => Master Value ) [date.timezone] => Array ( [0] => no value [1] => no value ) ) /** get a module setting */ function getModuleSetting($pModuleName,$pSetting) { $vModules = parsePHPModules(); return $vModules[$pModuleName][$pSetting]; } Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

same as above for configuration variables 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; }

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 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

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.

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; ?>
