error_log = logs/php-errors.log

Then you’ll be able to develop a parser for the php-errors.log file that can extract the PHP error log traces and parses them to extract the supply code file title and the road variety of every error discovered within the log file.

Right here is an instance of PHP code that may parse a line of a PHP error log to extract the supply file title and line quantity.

<?php
	$error_log_line="PHP Warning:  Use of undefined fixed sdfsdf - assumed "sdfsdf' (this wil throw an Error in a future model of PHP) in /residence/mlemos/rubbish/x.php on line 3';
	if(preg_match('/([^ ]+) on line ([0-9]+)/', $error_log_line, $m))
	{
		print_r($m);
	}

If you happen to run the instance code above, it is going to output this:

Array
(
    [0] => /residence/mlemos/rubbish/x.php on line 3
    [1] => /residence/mlemos/rubbish/x.php
    [2] => 3
)

As you may even see, the code creates an array with the title of the PHP supply file and the road variety of the code that brought about the error.

An entire error log processing script could be extra elaborated. It could additionally traverse all error log file traces and rely the variety of instances an error occurred in the identical line of the supply code file.

I’ll depart that half for you as an train to maintain this text transient.
