PHP Question

PHP - Log stacktrace for warnings?

Is it possible to log stacktraces for php warnings? Or catch a warning and error_log() it?

There's some code causing warnings in my error log, but it's impossible to know what's causing these warnings without knowing the stack trace.

Answer

There is an example of using set_error_handler() in conjunction with ErrorException to do just this:

http://us3.php.net/manual/en/class.errorexception.php

You would just need to implement your custom logging functionality inside of the handler function.


UPDATE:

Note, this also works for warnings, and many other error types. For full compatibility, see the manual for set_error_handler():
