Only true is EXACTLY true.
For example, is_array($_POST) will be EXACTLY true, as it returns true.
The reason for such a strict comparison is that strpos returns the
index of the found substring, so if your string starts with '<?',
strpos will return 0 (position 0).
In a large comparison, (0 == false), but in a STRICT one, (0 !==
FALSE).
if (strpos($buffer, '<?') !== FALSE)
means if we find '<php'
if (strpos($buffer, '<?') != FALSE)
means if we find '<?php', after the first character of buffer
