PHP Bug Type: Scripting Engine problem
Bug description: invalid fgets() return value when invalid resource supplied
Description:
------------
See the example code. It should return FALSE according to the manual (and
to common good sense).
This is causing valid code like
while (($str = fgets($fd)) !== FALSE) {
...
}
to go into infinite loop, which is very bad.
I tried to look at the source code but it looks correct, as it should
fall in file.c:1395, at the exit_failed label.
Reproduce code:
---------------
<?php
$fd = FALSE;
$retval = @fgets($fd);
var_dump($retval);
Expected result:
----------------
FALSE
Actual result:
--------------
NULL
