I Ctrl+clicked on a function error_log in the code to see how the 2nd param worked ($message_type) and it opened up file standard_3.php (not sure where this is coming from) and when I go to see what $message_type can be, all of the specifications are in an HTML table in the function comments; it's almost impossible to read.
Is this a PHP quirk or a PHPStorm quirk? Is there something to click to get those comments to be readable? I don't know why there's HTML split among code commenting. I clicked the function so I didn't have to go to php.net to look it up, plus we're using PHP 5.2 for legacy reasons.
