Bug #67689 [Opn]: require_once and include_once both fail to recognize previously included file

Edit report at https://bugs.php.net/bug.php?id=67689&edit=1 ID: 67689 Updated by: yohgaki@php.net Reported by: albertnelsen at earthlink dot net Summary: require_once and include_once both fail to recognize previously included file Status: Open Type: Bug Package: Scripting Engine problem Operating System: Linux Debian Wheezy PHP Version: 5.5.15 Block user comment: N Private report: N New Comment: I got different results from 5.4/5.5/5.6 (all of them are git checkout) with Fedora 20 x86_64. Same for fedora provided PHP 5.5. Debian might have patch for this. Fatal error: require_once(): Failed opening required 'src\ClassA.php' (include_path='.:/usr/local/php5.6/share/pear') in /home/yohgaki/workspace/ext/git/oss/php.net/PHP-5.6/t.php on line 3 [yohgaki@dev PHP-5.6]$ cat t.php <?php require_once "src/ClassA.php"; require_once "src\\ClassA.php"; "/" works under Windows as well as "\\". Thus, users are recommended to use "/" regardless of OS. Are we going to fix this? Previous Comments: ------------------------------------------------------------------------ [2014-07-26 23:08:24] albertnelsen at earthlink dot net Description: ------------ I'm using: PHP 5.5.15-1~dotdeb.1 (cli) (built: Jul 24 2014 16:44:04) on Linux unmapped 3.2.0-4-amd64 #1 SMP Debian 3.2.51-1 x86_64 GNU/Linux if you attempt to require_once or include_once the same file where the path differs only by the use of backslashes instead of forward slashes, PHP will attempt to include the file a second time. Test script: --------------- //Test1: require_once "src/ClassA.php"; require_once "src/ClassA.php"; //Test2: require_once "src\\ClassA.php"; require_once "src\\ClassA.php"; //Test3: require_once "src/ClassA.php"; require_once "src\\ClassA.php"; //Test4: require_once "src\\ClassA.php"; require_once "src/ClassA.php"; Expected result: ---------------- For this to work you need a file in the src/ClassA.php directory. Preferably one that declares and defines the ClassA class. Test1: This code should only include the file once and produce no errors. Test2: This code should only include the file once and produce no errors. Test3: This code should only include the file once and produce no errors. Test4: This code should only include the file once and produce no errors. Actual result: -------------- Test1: This code only includes the file once and produces no errors. Test2: This code only includes the file once and produces no errors. Test3: This code attempts to include the file twice resulting in a "Cannot redeclare class" error if the file contains a declaration of ClassA. Test4: This code attempts to include the file twice resulting in a "Cannot redeclare class" error if the file contains a declaration of ClassA. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=67689&edit=1
