How to see the errors in php code in chrome

Question

My php code is in the hostgator server and since I have to write a few scripts I don't have to install the wamp/lamp server.

I did a bit digging and found extensions namely PHP console. I added it and tested once, it showed me the line number of the errror.

But after a few hours when I tested the extension it is not working anymore for the same script and the same error.

I also tried another popular extension called Xdebug helper. But that also seems to be not working.

To test I have removed a semicolon in my working script and the link is : http://arqamahmad.com/music_app/getmusic.php

PS : I am using a shared hostgator server and I have done my research on the .htaccess and php.ini files. Nothing is helpful. The PHP console extension was the best but there seems to be some problem to that.

Answer : I had to add a php.ini file inside public_http making allowing the php debug mode on then only it the extensions work.

Answer 1

Step 1: Simply go to your server which you have installed (XXAMP, WAMP, MAMP, LAMP) search for php.ini

Step 2: Open this file in any text editor and search for display_errors and now set it to "on" like this display_errors = On

Step 3: Restart your server

Boom :)

For Firefox, there is FirePHP (http://www.firephp.org/) in combination with Firebug. There is a similar extension for Chrome, but I haven’t tested that (https://github.com/itsgoingd/clockwork-chrome).

The general thing is that you need to somehow transfer your error messages from PHP back to the client. If you don’t want to use a browser extension for that, you can also use an approach chosen by many frameworks (e.g. Symfony): add an admin module in your page, where the error messages are displayed (you need to intercept errors on the servers for that, by registering a custom error handler).

Edit: This of course requires PHP to output error messages at all, which depends on (among others) the php.ini settings like error_reporting, which need to be set to a level that the errors you desire for reporting will trigger the error handler functions.

Concerning your remark about Xdebug: to use Xdebug helper, Xdebug (a PHP extension for debugging) needs to be available on the server, which it usually is not on production systems.

Since php is executed on the server side, no browser add-on will help you. You need to add a few lines of code to the php file to show the errors.
