How can I get max file upload in bytes?

Question

I'm using ini_get('upload_max_filesize') to get the max file upload size.
The result is 5M.

What is the easiest way to get this in bytes?

Answer 1

You could use the return_bytes from the documentation:

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 * 1024 * 1024); //1073741824
            break;
        case 'm':
            $val *= (1024 * 1024); //1048576
            break;
        case 'k':
            $val *= 1024;
            break;
    }

    return $val;
}

return_bytes(ini_get('post_max_size'));
