#38549 [NEW]: Cannot reference name of file calling function

From: phpbugs at replies dot cyways dot com Operating system: Linux (CentOS 4.3) PHP version: 5.1.5 PHP Bug Type: Feature/Change Request Bug description: Cannot reference name of file calling function Description: ------------ It appears to be impossible to determine the name of a file that calls a function stored in another file, e.g., a class library included at startup. The __FILE__ variable returns the name of the script which contains the function called (the class library in this example), but there doesn't seem to be any comparable variable that returns the name of the file where the function is invoked. In my particular case, I have a simple library function debug('debugtext',trigger_level) which compares trigger_level to a global value and prints 'debugtext' as appropriate. I'd like to be able to print out the name of the file that called this function as well so I can trace errors more efficiently. As it stands now, I don't see any way to do this other than some kludge that uses get_included_files(). -- Edit bug report at http://bugs.php.net/?id=38549&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38549&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38549&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38549&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38549&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38549&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38549&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38549&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38549&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38549&r=support Expected behavior: http://bugs.php.net/fix.php?id=38549&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38549&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38549&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38549&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38549&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38549&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38549&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38549&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38549&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38549&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38549&r=mysqlcfg
