Bug #68133 [NEW]: Fatal error: require_once/include_once

From: pegasus at vaultwiki dot org Operating system: Centos 6 PHP version: master-Git-2014-10-02 (Git) Package: *General Issues Bug Type: Bug Bug description:Fatal error: require_once/include_once Description: ------------ When require_once($x) is used inside a method that takes $x as an argument by reference, the following error occurs: Fatal Error: require_once(): Failed opening '0`^,' ... If ZendOpcache is enabled, only: Fatal Error: require_once Checking the value of $x on the preceding line shows the correct value, and file_exists($x) on the proceeding line shows that PHP can find the file. If we do $y = $x; require_once($y); instead, or remove the reference, then the fatal error is bypassed. However, there are cases in the full use case where it is useful to change the required file within the method, and then have external access to the new filename thanks to the reference. Some notes: In the particular cases I've tested, the files have all been inside a symlinked directory, but I doubt that is related since it works if the reference is removed. Test script: --------------- class Test { public static function load(&$file) { require_once($file); } } $file = '/path/through/symlinked/directory/to/file'; // symlink is owned by root:root with 777 permissions // target directory is owned by PHP-run-as user Test::load($file); -- Edit bug report at https://bugs.php.net/bug.php?id=68133&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68133&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68133&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68133&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68133&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68133&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68133&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68133&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68133&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68133&r=support Expected behavior: https://bugs.php.net/fix.php?id=68133&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68133&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68133&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68133&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68133&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68133&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68133&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68133&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68133&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68133&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68133&r=mysqlcfg
