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.

There is an example of using
set_error_handler()in conjunction withErrorExceptionto do just this:https://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():https://php.net/set_error_handler
