[Animeonx]

Hola, me gustaría saber que hace este script.

Código php:

<?php
$zlibValue = (extension_loaded('zlib')) ? 1 : 0;
$str = "<br/>" . "validate_phpversion=" . phpversion() . ";";
$str .= "<br/>" . "validate_zlib=" . $zlibValue . ";";
$suhosin = extension_loaded('suhosin');
if($suhosin) {
$str .= "<br/>" . "validate_suhosin.post.max_vars=" . @ini_get('suhosin.post.max_vars') . ";";
$str .= "<br/>" . "validate_suhosin.request.max_vars=" . @ini_get('suhosin.request.max_vars') . ";";
$str .= "<br/>" . "validate_suhosin.request.max_totalname_length=" . @ini_get('suhosin.request.max_totalname_length') . ";";
$str .= "<br/>" . "validate_suhosin.request.max_varname_length=" . @ini_get('suhosin.request.max_varname_length') . ";";
$str .= "<br/>" . "validate_suhosin.get.max_varname_length=" . @ini_get('suhosin.get.max_varname_length') . ";";
$str .= "<br/>" . "validate_suhosin.get.max_name_length=" . @ini_get('suhosin.get.max_name_length') . ";";
}
echo $str;
ob_start();
@phpinfo(INFO_MODULES);
$output=ob_get_contents();
ob_end_clean();
?>
