PHP get actual maximum upload size

Question

When using

ini_get(\"upload_max_filesize\");

it actually gives you the string specified in the php.ini file.

It is not good to use

Answer 1

This is what I use:

function asBytes($ini_v) {
   $ini_v = trim($ini_v);
   $s = [ 'g'=> 1<<30, 'm' => 1<<20, 'k' => 1<<10 ];
   return intval($ini_v) * ($s[strtolower(substr($ini_v,-1))] ?: 1);
}
