#21515 [Opn]: debug_backtrace() needs documentation.

ID: 21515 Updated by: philip@php.net -Summary: Show the current functionname Reported By: gerwout@notenbomer.nl Status: Open Bug Type: Documentation problem Operating System: all PHP Version: 4.3.0 New Comment: __FUNCTION__ is now documented as per bug #19196. Am changing the topic of this bug report to reflect everyones deep desire for debug_backtrace() to be documented. We all agreed that the section on "Error Handling and Logging Functions" is the best place for debug_backtrace. Previous Comments: ------------------------------------------------------------------------ [2003-01-08 11:22:35] philip@php.net You can use the __FUNCTION__ constant as of PHP 4.3.0 It's documented somewhere with the other magical sorta-constants __FILE__, __LINE__, and __CLASS__. __CLASS__ also became available in PHP 4.3.0 I think there's a bug somewhere for documented these sorta-constants as the manual doesn't document them very well. ------------------------------------------------------------------------ [2003-01-08 04:27:05] derick@php.net hah, nu even de daad by het woord voegen :-) ------------------------------------------------------------------------ [2003-01-08 04:26:25] derick@php.net You can use debug_backtrace() for this (which is new in PHP 4.3.0). (Try var_dump(debug_backtrace()); to see what output it gives), marking this bug as a doc problem, as debug_backtrace() has not been documented yet. Derick ------------------------------------------------------------------------ [2003-01-08 04:20:36] gerwout@notenbomer.nl Is it possible to create a getCurrentFunctionName() function? If an user defined error occured (for example: you are not getting a valid SQL-resultset with your query) in a function, it would be handy to show the functionname where the error is generated. Possible example: function getQueryResultSet() { // requested code $currentFunctionName = getCurrentFunctionName(); $query="select * from table"; $result = mysql_query($query) or die ("The error occured in ". $currentFunctionName); return $result; } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21515&edit=1
