Kint PHP Debugger

説明

This WordPress plugin is a wrapper for the Kint 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.

Use this tool when you are debugging your website, in place of var_dump(), print_r() and debug_backtrace().

Handy Tools

Some handy tools just for the PHP Developer:

  • d( $var ); to render a collapsible UI container which displays your variable data in “the most informative way”
  • ddd( $var ); same as d() except that it also executes die() to halt execution.

Here are some variations of d() to give you the display you want:

  • ~d( $var ); outputs in plain text format.
  • +d( $var ); disregards depth level limits and outputs everything
  • !d( $var ); shows expanded rich output
  • -d( $var ); attempts to ob_clean() the previous output (dump something inside of HTML)

Profiler

Kint even includes a naïve profiler, which can help you analyze which blocks of code take longer than others:

Kint::dump( microtime() ); // just pass microtime()
sleep( 1 );
Kint::dump( microtime(), 'after sleep(1)' );
sleep( 2 );
ddd( microtime(), 'final call, after sleep(2)' );

See screenshot 2 for what is rendered out in your browser.

Admin Bar

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

インストール

From your WordPress dashboard

  1. Visit ‘Plugins > Add New’
  2. Search for ‘Kint PHP Debugger’
  3. Activate Kint PHP Debugger from your Plugins page.

Once Activated

Whenever you want to dump out the data within a variable, simply use d( $var ) to replace when you do pre + var_dump().

To dump and die, you use ddd( $var );.

FAQ

How do I use this utility?

When you are testing your code, you use d( $var ) in place of var_dump( $var ) and print_r( $var ). No need to wrap it in pre’s either.

What does it render in the browser?

Kint provides a handy UI that wraps up the data within the variable. Click to open it up and see the data.

See the screenshot 1 for an example.

What else does Kint provide to help me debug?

As you can see the screenshot 1, besides the handy UI, it also provides you with a full call stack. Click on the text below the UI to expand it out.

Can I run this on a live site?

I wouldn’t unless you are testing. This tool is for debug only. Once you push the site live, deactivate and delete this plugin.

What should I do when the site goes live?

Deactivate and delete this plugin.
