Bug description:Include within If Statement inputs blank string
Description:
------------
PHP Version: 5.3.2-1ubuntu4.7
When using an include() statement within an if statement, PHP always fails
with a seemingly blank input.
However, when used normally (obviously) it works fine, and when assigning
the return value to a variable and then testing the value of the variable,
include() works as intended.
Something that may or may not be a factor in this bug is that I have
appended to the default include path; however, logically in all test cases
(both in the actual project and the test script to create this bug report)
this seems irrelevant to the bug.
Test script:
---------------
<?php
/*
$v = include_once("blank.php");
if(!$v)
echo "FAILED";
else
echo "SUCCESS";
*/
if( include_once("blank.php") != true)
echo "FAILED";
else
echo "SUCCESS";
?>
Expected result:
----------------
As is, the script should run just like a normal function; why it behaves in
this matter only within in an if-then statement is the bug.
The script above -should- output FAILED if there is not a script entitled
"blank.php", and SUCCESS if there is.
Actual result:
--------------
The script above, as-is, believes there is a blank string being inputted
into the include() call, when in reality there is a perfectly valid
filename. If you comment out the second half of the script and uncomment
the first part, it works perfectly fine.
