php - warning feof() expects parameter 1 to be resource -


my error logs getting out of control 2 below errors

warning feof() expects parameter 1 resource

and

warning fread() expects parameter 1 resource

the bit of code responsible is

<?php     $file = '../upload/files/' . $filex;     header("content-disposition: attachment; filename=" . urlencode($file));     header("content-type: application/force-download");     header("content-type: application/octet-stream");     header("content-type: application/download");     header("content-description: file transfer");     header("content-length: " . filesize($file));     flush(); // doesn't matter.      $fp = fopen($file, "r");     while (!feof($fp)) {         echo fread($fp, 65536);         flush(); // essential large downloads     }     fclose($fp); ?>

i used code header downloads freaking out right - before asks have tried, tried google still don't understand error message.

fopen fails , returns false. false not resource, warning.

you'd better test $fp before injecting resource-like argument:

if(($fp = fopen($file, "r"))) {     [...] }
