How can I save a PHP backtrace to the error log?

Question

I'm using this right now:

error_log(serialize(debug_backtrace())); 

But I have to unserialize it every time. Is there a better way to store backtraces?

Answer 1

This should generate a readable string:

error_log(print_r(debug_backtrace(), true)); 

Additionally, debug_print_backtrace() prints the back trace as string and its output can be captured with regular output buffer functions:

ob_start(); debug_print_backtrace(); error_log(ob_get_clean()); 

Answer 2

From my perspective the best approach is using an exception functionality:

$e = new Exception(); $e->getTraceAsString();
