PHP Console allows you to handle PHP errors & exceptions, dump variables, execute PHP code remotely and many other things using <a href="https://chrome.google.com/webstore/detail/php-console/nfhmhhlpfleoednkpnnnkolmclajemef" rel="nofollow ugc">Google Chrome extension PHP Console</a> and <a href="https://github.com/barbushin/php-console" rel="nofollow ugc">PHP Console server library</a>.
</blockquote>
This implementation of PHP Console is a handy tool to make it easier to test on the fly any WordPress specific function or class (including those introduced by your active theme and plugins!) from a terminal and inspect results, catch errors and warnings with complete call stack trace straight from the Chrome JavaScript console. In other words, besides debugging, you can execute PHP or WordPress-specific PHP code straight from the terminal and print PHP variables in Chrome Dev Tools JavaScript console along with your normal JavaScript debugging and testing. Keep everything in one place, without leaving the browser to check for your logs or writing temporary PHP test code on a PHP file and refresh your browser page.
Note: PHP version 5.6.0 or above is required to use this plugin.

<h3>Usage</h3>
After you entered WP PHP Plugin password, your browser address bar should show a yellow “key” icon, which, if clicked, will prompt for the password you have set earlier. 
The “key” icon will change into a “terminal” icon, click on it to open the PHP Console eval & options form.
After entering the correct password, you can use the Eval Terminal in the PHP Console eval & options form and run any PHP code from it, including WordPress’s own functions: enter one or more lines of PHP code in the black Eval terminal screen, press Ctrl+Enter and see the result in Chrome Dev Tools JavaScript console. 
The result includes the output, the return value and the net server execution time.
In your PHP code on the Server, you can call PHP Console debug statements like <code>PC::debug( $var, $tag )</code> to display PHP variables in the JavaScript console and optionally filter selected tags through the PHP Console eval & options form opened from the address bar in your browser.
In the JavaScript console you will see printed any `PC::debug()“ information, PHP errors, warnings, notices with optional stack trace, which will be useful to debug your plugin or theme.
