Bug #67017 [Com]: include_once() in if statement is taking incorrect parameter

Edit report at https://bugs.php.net/bug.php?id=67017&edit=1 ID: 67017 Comment by: william75 at yopmail dot com Reported by: seufert at gmail dot com Summary: include_once() in if statement is taking incorrect parameter Status: Open Type: Bug Package: Scripting Engine problem Operating System: Mac OS/X 10.9 PHP Version: 5.6.0alpha3 Block user comment: N Private report: N New Comment: That is no bug, include_once/require_once is a language construct not a function, so include_once("myclass.php") === FALSE can (should) be written as include_once "myclass.php" === FALSE which binds like include_once ("myclass.php" === FALSE) which evaluates to include_once FALSE which converts to include_once "" which fails. Both manual pages for "include_once" (used in your bug summary) and "require_once" (used in your description and script) ultimately link to the "include" documentation [ http://www.php.net/manual/en/function.include.php ] which warns about that: """ Because include is a special language construct, parentheses are not needed around its argument. Take care when comparing return value. Example #4 Comparing return value of include <?php // won't work, evaluated as include(('vars.php') == 'OK'), i.e. include('') if (include('vars.php') == 'OK') { echo 'OK'; } // works if ((include 'vars.php') == 'OK') { echo 'OK'; } ?> """ Incidentally, testing ((require_once "myclass.php") === FALSE) or (FALSE === require_once "myclass.php") in your script is useless since, as opposed to include/include_once, a failing require/require_once will produce a fatal error and stop the execution.

If you change the script to FALSE === require_once(...) it works perfectly. Test script: --------------- <?php if(require_once("myclass.php") === FALSE) { echo "Hi there was a problem"; } new myclass(); Expected result: ---------------- No errors Actual result: -------------- Inappropriate ioctl for device in /.../test.php on line 2 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67017&edit=1
