PHP error reporting: line number AND relevant line of code?

Question

I'm attempting to write all of my PHP errors to a log file. I'm interested in including not just the line number, but also the specific line of code associated with that line number. This is the code I have so far. What would I have to add/change in order to report the problematic lines of code?

error_reporting(E_ALL);
ini_set('html_errors', 1);
ini_set("log_errors", 1);
ini_set("track_errors", 1);
ini_set("error_log", "./php-error.log");

I'm not sure how I would integrate those with the log's output. I tried adding "error_log(print_r(debug_backtrace(), true));", but that just gave a blank array. What am I doing wrong? Thanks! — user3092995

I've looked into the documentation and tried adding it to my code, but I'm still not seeing how I can get it to report the actual line of code that's throwing the notice (I'm mainly dealing with undefined constant/variable issues). — user3092995

There is no solution to automatically print the line of code. You can however get the file and line number using debug_backtrace(). Then you can read the file yourself and find the right line and print it.

Ok, thanks! That's good to know, so I don't go off on a wild goose chase. :) The script I have already prints the line number, so I'll just copy-paste the code into Excel to find the problematic string of code.
