I’ve got some errors in my php_errors.log like this:
[09-Apr-2011 09:32:33] PHP Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /var/www/vhosts/domain1.xxx/httpdocs/includes/lib.php on line 30
As suggested in the path, lib.php is an include, however I don’t know where it is being included! In fact, the errors are triggered when visiting a different domain hosted on our server. I’ve tried grep’ing for various strings in files under that domain, without success so far.
What would be really handy is a debug command I could stick somewhere that would print out the path & file that lib.php is included within, either in the php_error log or maybe there’s a line I can put within the function in lib.php where the error is triggered.
