#35174 [NEW]: Lack of extension dependency checking & misleading error message.

From: iceberg at verycool dot co dot uk Operating system: win xp PHP version: 5.0.5 PHP Bug Type: *Configuration Issues Bug description: Lack of extension dependency checking & misleading error message. Description: ------------ Lack of extension dependency checking & misleading error message. Attempting to load an extension when a preprequisite dll is missing seems to yield the same message as if the extension were missing. (vis. "the specified module could not be found"). This seems to be causing an innordinate amount of confusion (Judging by the number of "bogus bugs" and USENET posts resulting from this). Reproduce code: --------------- exists c:\php\php_openssl.dll ; php.ini extension_dir = "C:\php" extension=php_openssl.dll -- Edit bug report at http://bugs.php.net/?id=35174&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=35174&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=35174&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=35174&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=35174&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=35174&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=35174&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=35174&r=needscript Try newer version: http://bugs.php.net/fix.php?id=35174&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=35174&r=support Expected behavior: http://bugs.php.net/fix.php?id=35174&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=35174&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=35174&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=35174&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=35174&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=35174&r=dst IIS Stability: http://bugs.php.net/fix.php?id=35174&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=35174&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=35174&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=35174&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=35174&r=mysqlcfg
