fgets expects a literal for the buffer size argument. It hangs until the max_execution_time timeouts, when you give it a variable.

Reproduce code:
$url = '';
if (($handle = fopen($url, 'r')) === false) {
    die('Couldnt open url '.$url.'.');
while (feof($handle) === false) {
    $text = fgets($handle, $kBufferSize); // doesn't work
    //$text = fgets($handle, 512); // works

Expected result:
The google homepage (i.e. the given url)

Actual result:
Timeout on max_execution_time.

The reproduce code (obviously) lacks the $kBufferSize declaration.
$kBufferSize = 512; 
.... or something similar
