Easily dump and centrally inspect your PHP variables for convenient debugging.

## Description

Variable Inspector allows you to easily inspect your PHP $variables in a visually clean manner at a central location in wp-admin. It aims to be an **easy and useful enough debug tool**. 

In scenarios where [Xdebug](https://xdebug.org/) or even something like [Ray](https://myray.app/) is not ideal or simply an overkill, Variable Inspector provides **a single-line code** (see "How to Use" below) to be used instead of [var_dump()](https://www.php.net/manual/en/function.var-dump.php), [var_export()](https://www.php.net/manual/en/function.var-export.php) and [print_r()](https://www.php.net/manual/en/function.print-r.php). 

Nothing is shown to site visitors nor being output on the frontend, and the **$variable content is nicely formatted for review** using var_dump(), var_export() and print_r() on the inspector page in wp-admin. Additionally, because it is a regular WordPress plugin, you simply install, activate and use without the need for complicated configuration.

Variable Inspector was originally inspired by [WP Logger](https://wordpress.org/plugins/wp-data-logger/).


### How to Use

Simply place the following line anywhere in your code after the `$variable_name` you'd like to inspect:

`do_action( 'inspect', [ 'variable_name', $variable_name ] );`

If you'd like to record the originating PHP file and line number, append the PHP magic constants `__FILE__` and `__LINE__` as follows.

`do_action( 'inspect', [ 'variable_name', $variable_name, __FILE__, __LINE__ ] );`

This would help you locate and clean up the inspector lines once you're done debugging.
