<p>Debug Toolkit makes debugging your code easier and more enjoyable.  It provides you with interactive and helpful tools:</p>
<ul>
<li>Better PHP error interface from (<a href="http://filp.github.io/whoops/" rel="nofollow ugc">Whoops</a>)</li>
<li>Better variable inspection – no need to use <code>var_dump</code>, <code>print_r</code>, or X-debug</li>
<li>An interactive way to back trace the program’s execution order</li>
</ul>
<h3>Better PHP Error Interface from Whoops</h3>
<p>The built-in PHP error container is basic and not as helpful as it could be.  On top of that, it’s rather ugly. Wouldn’t you agree?</p>
<p>Whoops gives you a cool interface that is helpful, interactive, and quite nice to look at.  Some features:</p>
<ul>
<li>Provides the error message and links to search Google, DuckDuckGo, and Stack Overflow.</li>
<li>Shows the actual code where the error occurred.</li>
<li>Provides an interactive call stack.  Click each and the actual code appears in the viewer panel.</li>
<li>Environment and details including GET Data, POST Data, Files, Cookie, Session, Server/Request Data, Environment Variables, and Registered Handlers.</li>
</ul>
<p>See the tools in action in this video</p>

<h3>Better Variable Inspection</h3>
<p>Though X-debug is powerful, it can be difficult to set up and run.  For that reason, it’s common to dump or print out the variable to browser.  But the built-in display for the PHP <code>var_dump</code> and <code>print_r</code> is basic.</p>
<p>This plugin includes both two very popular variable dumper tools:</p>
<ul>
<li><a href="https://symfony.com/doc/current/components/var_dumper.html" rel="nofollow ugc">VarDumper from Symfony</a></li>
<li><a href="https://kint-php.github.io/kint/" rel="nofollow ugc">Kint – a modern and powerful PHP debugging helper</a></li>
</ul>
<p>VarDumper provides a simple container that displays where you place it.</p>
<p>On the other hand, Kint provides a more powerful interface that gives you more information such as printing out the expression that was passed into it, the data type, memory size, and the value.</p>
<p>To make it even easier, the following utility functions are available for you to use in your code:</p>
<h4>Available Functions for Inspecting Variable Values</h4>
<p>Let’s explore the functions that are available for you through this plugin.  We’ll use the variable inspectors to dump <code>global $post</code>.</p>
<p>Note: You can pass in any variable or function that returns a value.</p>
<p>Dumps the given variable(s):</p>
<pre><code>global $post;

// VarDumper
vdump( $post );

// Kint
dump( $post );
</code></pre>
<p>Dumps the given variable(s) and then exits the program’s execution:</p>
<pre><code>global $post;

// VarDumper
vdump_and_die( $post );

// Kint
dump_and_die( $post );
</code></pre>
<p>In addition, there are alias (shorthand) functions available for you if you prefer shorter function names:</p>
<ul>
<li><code>vd()</code> is an alias for <code>vdump()</code></li>
<li><code>vdd()</code> and <code>vdd()</code> are aliases for <code>vdump_and_die()</code></li>
<li><code>d()</code> is an alias for <code>dump()</code></li>
<li><code>dd()</code> and <code>ddd()</code> are aliases for <code>dump_and_die()</code></li>
</ul>
<h3>Tracing Call Stack</h3>
<p>When debugging, there are times when you need to see the order in which functions were called that lead to a certain point in the program.  PHP offers a backtrace that traces back the execution order from the point when the function is invoked.</p>
<p>To make backtracing easier, this plugin provides you with a <code>trace()</code> function and combines it with the variable inspect functions.</p>
<p>For example, if you wanted to trace the call stack to the start of the loop in your theme’s <code>functions.php</code> file, you could use this code:</p>
<pre><code>add_action( 'loop_start', function() {
    trace();
} );
</code></pre>
<h4>Available Trace Functions</h4>
<p>Place these functions at the point where you want to trace the call stack.</p>
<ul>
<li><code>trace();</code></li>
<li><code>trace_vdump();</code> – Combines <code>trace()</code> and <code>vdump()</code></li>
<li><code>trace_dump();</code> – Combines <code>trace()</code> and <code>dump()</code></li>
<li><code>trace_vdump_and_die();</code> – Combines <code>trace()</code> and <code>vdump_and_die()</code></li>
<li><code>trace_dump_and_die();</code> – Combines <code>trace()</code> and <code>dump_and_die()</code></li>
</ul>
<p>In addition, there are alias (shorthand) functions available for you if you prefer shorter function names:</p>
<ul>
<li><code>tracevd();</code> – Combines <code>trace()</code> and <code>vd()</code></li>
<li><code>traced();</code> – Combines <code>trace()</code> and <code>d()</code></li>
<li><code>tracevdd();</code> – Combines <code>trace()</code> and <code>vdd()</code></li>
<li><code>tracedd();</code> – Combines <code>trace()</code> and <code>dd()</code></li>
<li><code>tracevddd();</code> – Combines <code>trace()</code> and <code>vddd()</code></li>
<li><code>traceddd();</code> – Combines <code>trace()</code> and <code>ddd()</code></li>
</ul>

Debug Toolkit

This is a must have plugin if you do any kind of PHP coding for WordPress. It makes the difficult aspects of debugging code easy. You'll spend less time debugging and more time writing great functionality.

Very Nice!! A must have...

Thanks for creating this. Another must have in my plugin development workflow!

Another must have!

I've just discovered this plugin after years of WP development and it's super useful! I'm not a fan of xDebugging variables; debugging big objects and arrays with dump() or vdump() is very cool, as you can easily open up and close the tree to navigate through it more easily.
Nice work!

Excellent developer companion plugin

Wonderful plugin to debug errors. A feature request would be to dump the variable in debug.log file as well when define( 'WP_DEBUG_LOG', true ); is set in config file.

Wonderful Plugin

This is a great new plugin, and I love having the option to use Kint or VarDumper, they're invaluable. Having Whoops in there is a major plus. Tonya rocks!

Part of my build setup on every site now.

A must have!

This plugin is amazing, Highly recommended for developers. 

Really worth it !

One of my favourite plugin. Helps a lot with development and debugging. Please keep it update or if we could get a chance to contribute we would love that.

Best Plugin For Devs


This is a must have developers tool. Can't work without it. Highly recommend it.


Saved me many times

Code debug made easier and more enjoyable.

<p>This WordPress plugin is a wrapper for the <a href="https://kint-php.github.io/kint/" rel="nofollow ugc">Kint</a> PHP Debugger utility version 1.x.  Now instead of using var_dump() or print_r(), you simply use d() with zero, nadda, no formatting required.</p>
<p>Use this tool when you are debugging your website, in place of <strong><a href="http://php.net/manual/en/function.var-dump.php" rel="nofollow ugc">var_dump()</a></strong>, <strong><a href="http://php.net/manual/en/function.print-r.php" rel="nofollow ugc">print_r()</a></strong> and <strong><a href="http://php.net/manual/en/function.debug-backtrace.php" rel="nofollow ugc">debug_backtrace()</a></strong>.</p>
<h4>Handy Tools</h4>
<p>Some handy tools just for the PHP Developer:</p>
<ul>
<li><code>d( $var );</code> to render a collapsible UI container which displays your variable data in “the most informative way”</li>
<li><code>ddd( $var );</code> same as d() except that it also executes <code>die()</code> to halt execution.</li>
</ul>
<p>Here are some variations of <code>d()</code> to give you the display you want:</p>
<ul>
<li><code>~d( $var );</code> outputs in plain text format.</li>
<li><code>+d( $var );</code> disregards depth level limits and outputs everything</li>
<li><code>!d( $var );</code> shows expanded rich output</li>
<li><code>-d( $var );</code> attempts to ob_clean() the previous output (dump something inside of HTML)</li>
</ul>
<h4>Profiler</h4>
<p>Kint even includes a naïve profiler, which can help you analyze which blocks of code take longer than others:</p>
<pre><code>Kint::dump( microtime() ); // just pass microtime()
sleep( 1 );
Kint::dump( microtime(), 'after sleep(1)' );
sleep( 2 );
ddd( microtime(), 'final call, after sleep(2)' );
</code></pre>
<p>See <a href="https://wordpress.org/extend/plugins/kint-php-debugger/screenshots/" rel="ugc">screenshot 2</a> for what is rendered out in your browser.</p>

<p>“KINT ACTIVE” indicator displays in the WordPress admin bar to alert you when the plugin is active.</p>


Kint PHP Debugger

Really like to debug with Kint, and this plugin makes it much easier.



Useful

Love this plugin. Displays more than var_dump does and is so much easier to read the output. Handy toggle to display more information is very helpful. Love that ddd() option to display and stop execution. Thank you!!!



Improves Workflow and Troubleshooting

Thanks for this plugin. It makes debugging my arrays of arrays of arrays much simpler. ;)

Works great!

Saves a lot of time when writing plugins and themes.
Thanks!

Update 2/11/2021 - even though this plugin hasn't had any updated in more than 2 years, it is still working just great.

Does what it says

Kint is a modern and powerful PHP debugging helper, which requires zero-setup and replaces var_dump(), print_r() and debug_backtrace().
