i use a for loop to unset all of the leftover variables in my script, to save some memory. My question is, will unset($variable); delete $variable if it is a PHP gd resource, like the one created with $variable = imagecreatefrompng('url');?

  • you should use imagedestroy funtion, check http://php.net/manual/en/function.imagedestroy.php – kraysak Apr 10 '15 at 01:46
  • @kraysak I know i can do that but there's over 50 GD resources and i can't just go through each one of them, so i have a function that unsets all variables, some of those variables are PHP gd resources and i was wondering if unset could destroy those as well. – Mister_Fix Apr 11 '15 at 08:55
