After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. ' into '), so I created my own by improving on the existing ones:
function phpinfo2array() {
$entitiesToUtf8 = function($input) {
// http://php.net/manual/en/function.html-entity-decode.php#104617
return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
};
$plainText = function($input) use ($entitiesToUtf8) {
return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
};
$titlePlainText = function($input) use ($plainText) {
return '# '.$plainText($input);
};
ob_start();
phpinfo(-1);
$phpinfo = array('phpinfo' => array());
// Strip everything after the <h1>Configuration</h1> tag (other h1's)
if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
return array();
}
$input = $matches[1];
$matches = array();
if(preg_match_all(
'#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
'(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
$input,
$matches,
PREG_SET_ORDER
)) {
foreach ($matches as $match) {
$fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
if (strlen($match[1])) {
$phpinfo[$match[1]] = array();
} elseif (isset($match[3])) {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
} else {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $fn($match[2]);
}
}
}
return $phpinfo;
}
The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):
