When writing some PHP scripts or HTML scripts I like to know what the mistake are when I test the script.  Is there any type of coding I can add to a PHP or HTML program that will tell me what line of code it stopped at ?

HTML is not script, it's a markup language. It will either display or not display depending on the magnitude of the error and the browser's ability to correct your bad markup (most browsers are pretty good at this).

If you open an HTML page in any decent text editor that does syntax highlighting (Programmer's Notepad, Notepad++, Sublime) it will become pretty obvious where your mistakes are if the syntax is off.

For PHP, different story.  Add the following code to the top of your PHP scripts:

ini_set('display_errors',1); 
 error_reporting(E_ALL);

Open in new window


That should force the script to send any errors to the browser for your reading enjoyment.  Just make sure to remove those or comment them out before deploying the script in a production environment.

You might want to learn about Google Chrome Dev Tools.  This will take you an entire day of your life and it will put you about a year ahead of other developers who have not chosen the power.  Use the power wisely.

For HTML and the HTML generated by PHP, there is the W3C Validator http://validator.w3.org/ which will tell you about HTML errors and non-standard syntax.
