Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:

// start output buffering
ob_start();// send phpinfo content
phpinfo();// get phpinfo content
$html = ob_get_contents();// flush the output buffer
ob_end_clean();// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], 'no value', $html);
if (isset($_SERVER['AUTH_PASSWORD'])) $html = str_replace($_SERVER['AUTH_PASSWORD'], 'no value', $html);

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).

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

tags also had an align="center". So this update changes the regex for those tags:

/* parse php modules from phpinfo */function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();$s = strip_tags($s,'

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

To display everything:

    foreach($phpinfo as $name => $section) {
        echo "

$name

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 tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)

we need to change two lines:

preg_match ('%.*?(.*)%s', ob_get_clean(), $matches);
?>
to
preg_match ('%.*?(.*?)%s', ob_get_clean(), $matches);
?>

and

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

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

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 is optional

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

One note on the very useful example by "jon at sitewizard dot ca". 
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];

These two lines will produce the error "Strict Standards:  Only variables should be passed by reference in...".  The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:

Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];

This fixes the error.
To wrap it all in an example:
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());

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

The phpinfo output is wrapped within a

'.print_r($value, true).'
