How do i view php errors in chrome?

May 08, 2013

PHP errors can be a obnoxious when you’re developing an XHR heavy application with lots of JSON responses. The errors just aren’t very readable. So today I finally decided to implement ChromeLogger in our application here at work. This is one thing I’ve always missed since moving away from FireFox and its excellent plugin FirePHP.

First install ChromeLogger.

Setting up Chrome Logger and Error Handling

After installing the chrome plugin you’ll want to add the associated server-side library to app/Vendor/ChromePhp/ChromePhp.php. Next create a new file for handing errors in your CakePHP 2 project. Create a new class at app/Lib/AppError.php and add in the following code:

App::import('Vendor', 'ChromePhp/ChromePhp');
//in app/Lib/AppError.php
class AppError {
    public static function handleError($code, $description, $file = null, $line = null, $context = null) {
        ChromePhp::error('PHP Error Code '.$code.': '.$description.' '.$file.':'.$line);
    }
}

Next adjust your core.php and bootstrap.php files as follows.

In core.php

 'AppError::handleError',
    'level' => E_ALL & ~E_DEPRECATED,
    'trace' => true
));

In bootstrap.php

App::uses('AppError', 'Lib');

You’re done! For more information in AppError review the CakePHP2 documentation.

Setting up Chrome Logger For SQL Logging

Since most applications we write these days are XHR heavy the standard SQL Log CakePHP ships with is rendered useless. If you’re like me and obsess about optimizing queries then you’ll probably want all your queries logged to the Chrome Console. To add this functionality to your application open up your AppController and add the following to your afterFilter.

Now just set Configure::write(‘debug’,2) when you want to see queries exported to your Chrome Console. You’ll notice that I set all queries that took more than 100 milliseconds to appear as warnings and everything else as informational. Check out my blog for more CakePHP tutorials.
