Bug #17551 Updated: PHP4.10 and PHP4.20 includes different files when calling include_once()

ID: 17551 Updated by: ulysses@mail.fitan.com.tw Reported By: ulysses@mail.fitan.com.tw -Status: Bogus +Status: Open Bug Type: Scripting Engine problem Operating System: Windows 2000 (IIS5.0) PHP Version: 4.2.0 New Comment: I am not playing with PHP. It my job and I am developing a Stock-MRP-Accounting system for my client and I have problems switching from 4.10 to 4.20. Maybe I should describe the real situation to you. I have these files: c:/inetpub/wwwroot/stock/stock_amend.php c:/inetpub/wwwroot/stock/edit/stock_amend.approve.php c:/inetpub/wwwroot/stock/class/notification.class.php 1. The stock_amend.php is the main entrance. When user invoke stock_amend.php with POST, stock_amend.php will call: include_once('edit/stock_amend.approve.php') to execute authorization and data modifications. 2. In edit/stock_amend.approve.php program will conditionally calling include_once('class/notification.class.php'); to make logs. Now the problem is, these codes works fine on my developing platform (PHP4.10), but they failed to work on my client's server (PHP4.20). I've got this message: Warning: Failed opening 'class/notification.class.php' for inclusion (include_path='c:\php4\pear') in c:/inetpub/ wwwroot/stock/edit/stock_amend.approve.php on line 105 Now I rewrite my experimental codes: c:/inetpub/wwwroot/test/a.php c:/inetpub/wwwroot/test/inc/b.php c:/inetpub/wwwroot/test/cls/c.php c:/inetpub/wwwroot/test/inc/cls/c.php test/a.php: <? echo "<BR>I'm a.php (".__FILE__.")"; include_once("inc/b.php"); ?> test/inc/b.php: <? echo "<BR>I'm b.php (".__FILE__.")"; include_once("cls/c.php"); ?> test/cls/c.php: <? echo "<BR>I'm CORRECT c.php (".__FILE__.")"; ?> test/inc/cls/c.php: <? echo "<BR>I'm WRONG c.php (".__FILE__.")"; ?> PHP 4.10 shows this result: I'm a.php (c:/inetpub/wwwroot/test/a.php) I'm b.php (c:/inetpub/wwwroot/test/inc/b.php) I'm CORRECT c.php (c:/inetpub/wwwroot/test/cls/c.php) But PHP4.20 shows this result: I'm a.php (c:/inetpub/wwwroot/test/a.php) I'm b.php (c:/inetpub/wwwroot/test/inc/b.php) I'm WRONG c.php (c:/inetpub/wwwroot/test/inc/cls/c.php) Of course I know that I can use full path in include_once() to prevent this problem. The point is: PHP4.10 AND PHP4.20 DID INCLUDE DIFFERENT FILES AND I AM NOT TALKING ABOUT __FILE__. There is nothing wrong with __FILE__ in 4.10 and 4.20. They all present the correct file path.

Here is an example. Consider the following file structure: c:/inetpub/wwwroot/test/a.php c:/inetpub/wwwroot/test/inc/b.php c:/inetpub/wwwroot/test/cls/c.php c:/inetpub/wwwroot/test/inc/cls/c.php test/a.php: <? echo "<BR>now in ".__FILE__; include_once("inc/b.php"); ?> test/inc/b.php: <? echo "<BR>now in ".__FILE__; include_once("cls/c.php"); ?> test/cls/c.php and test/inc/cls/c.php <? echo "<BR>now in ".__FILE__; ?> PHP 4.10 shows this result: now in c:/inetpub/wwwroot/test/a.php now in c:/inetpub/wwwroot/test/inc/b.php now in c:/inetpub/wwwroot/test/cls/c.php But PHP4.20 shows this result: now in c:/inetpub/wwwroot/test/a.php now in c:/inetpub/wwwroot/test/inc/b.php now in c:/inetpub/wwwroot/test/inc/cls/c.php I did not found related announcement in the 4.20 and 4.21 release notes, so I think it is a bug (or at least an incompatiable issue.) Here are my php.ini settings (in both 4.10 and 4.20): 1. Enable register_globals 2. Disable magic_quote_gpc 3. Change execution time limit to 60sec 4. Change max memory limit to 12MB 5. Change default_charset to big5 6. Change doc_root to c:/inetpub/wwwroot 7. Enable MSSQL extension 8. Disable cgi.force-redirect (in PHP4.20) 9. Install ZendOptimizer ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17551&edit=1
