Bug description: Optimizing Bug for 'sizeof' function
There is a huge diference in speed with these two approaches:
$file=file("file.txt");
1.
for($i=0;$i<sizeof($file);$i++)
...
2.
$file_size=sizeof($file);
for($i=0;$i<$file_size;$i++)
...
The second approach is much more faster, because the first seems to
calculate the 'sizeof' in every iteration.
