Re: error handling and __LINE__

| Thanks, assert() is cool, but it still reports the filename and line | number of the included file with the function in which the error | occurred, not the script that called the functon with illegal arguments. | Or...??? I see, you need a debugger :) I wrote an errorhandler class with error trapping capability. It works as follows: --index.php <?php $error = new ErrorHandler; include_once('functions.php'); $error->set_error_trap(E_ALL); // switch error trapping _on_ ! foo(123); // illegal parameter to be passed if ( $error->is_trapped(E_WARNING) ) { $this->set_error_trap(); // switch error trapping _off_ !! // following errors will be handled normally trigger_error('The place where foo() fails.', E_USER_ERROR); } ?> if you run this script, then though foo() raises a warning which won't be displayed but stored in $error (error handling object) and later you can "search" in the trap ( with is_trapped() ) to determine whether a particular error occured while the trap was switched on. Does it satisfy you or not? If yes, please mail me directly. | | Eg.: | index.php: | <? | include_once("functions.php"); | // foo() is declared here | foo(123); | // illegal argument | ?> | | This will produce a message saying an error occurred in functions.php, | but I want it to tell me that the error occurred in index.php, line 3. | Because if I call foo() many times in a script, it is difficult to find | out which call that failed. | | Is this impossible? | | Papp Gyozo wrote: | | > try, assert() instead of echo()ing error messages. | > | > assert('is_object($obj)'); | > | > and write your error handler code or use mine :) | > or am i missing something? | > | > Papp Gyozo | > - pgerzson@freestart.hu | > | > ----- Original Message ----- | > From: "SafeV" <nedenom@hotmail.com> | > To: <php-general@lists.php.net> | > Sent: Thursday, November 22, 2001 4:15 PM | > Subject: [PHP] error handling and __LINE__ | > | > | > | Hi, | > | I wonder if there's a way to find the line number of the calling script | > | from a function, like the error messages PHP generates.
