A quick way too check your setup is normally called phpinfo.php and looks like this. You will be pleasantly supprised at the amount of data it provides:


Thank you rch1231, but my problem is. I am creating a setup script for my application, where it has to show max_upload_filesize and something stuff like that, I am retrieving it using ini_get(' '),is there anything that I can get its value using ini_get(' ')

phpinfo gives you the data and more but you need something to show it in php...

Our php.ini contains the following settings:

display_errors = On
register_globals = Off
post_max_size = 8M

echo 'display_errors = ' . ini_get('display_errors') . "\n";
echo 'register_globals = ' . ini_get('register_globals') . "\n";
echo 'post_max_size = ' . ini_get('post_max_size') . "\n";
echo 'post_max_size+1 = ' . (ini_get('post_max_size')+1) . "\n";
echo 'post_max_size in bytes = ' . return_bytes(ini_get('post_max_size'));

function return_bytes($val) {
    $val = trim($val);
    $last = strtolower($val[strlen($val)-1]);
    switch($last) {
        // The 'G' modifier is available since PHP 5.1.0
        case 'g':
            $val *= 1024;
        case 'm':
            $val *= 1024;
        case 'k':
            $val *= 1024;

    return $val;


You can't get information on installed extentions that way (as far as I know). You could check for FUNCTIONS; for example, to check for OPENSSL, you could do >

if (function_exists('openssl_open')) {
echo "OPENSSL functions are available";
} else {
echo "OPENSSL functions are not available, thus, OPENSSL isn't installed!";

For zip, just check for zip_open.
Good luck.
