Beschreibung
Variable Inspector allows you to easily inspect your PHP $variables in a visually clean manner at a central dashboard in wp-admin. It aims to be an easy and useful enough dev and debug tool.
It provides a single-line code to inspect your variable (see „How to Use“ below). 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 dashboard in wp-admin.
It’s a real time-saver for scenarios where Xdebug or even something like Ray is not ideal or simply an overkill. For example, when coding on a non-local environment via tools like Code Snippets, WPCodeBox, Scripts Organizer or Advanced Scripts. Additionally, because it is a regular WordPress plugin, you simply install, activate and use without the need for complicated configuration.
What Users Say
„Huge time-saver when working with PHP variables.“ ~Jeff Starr
„Works great! Love this thing.“ ~Josh
„Every developer need it. You can debug easily every variable.“ ~Pexle Chris
„All I need. Enough to test the function of snippets. Works flawless.“ ~@tesig
„It does what it does very well, and doesn’t try to do everything.“ ~@swb1
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.

PRO Version
If you need something more versatile for larger, more complex projects, these PRO features might come in handy:
- vi( $variable ) inspector to replace the do_action() above and automatically includes the file path and line number. Or, use vis( $variable_name, ‚variable_name‘ ) when inspecting in/via code snippets plugins (Code Snippets, WPCodeBox, Scripts Organizer, etc.) or custom code module of page builders (Bricks, Oxygen Builder, etc.)
- dump_print_r and dump_print_tree viewers: both viewers combines var_dump and print_r, with the later allowing for collapsing and expanding data nodes, which is especially useful for inspecting long and complex arrays and objects.
- kint viewer: an advanced viewer with table view for multi-dimensional arrays, node access path info, capability to search inside variables, pop-up window viewing and advanced info for your complex objects, e.g. available methods and static class properties.
- Categorize and filter results by color. This, for example, allows you to categorize $variables according to which stage they’re in inside your code.
- Add counter or notes to inspection results. Another way to tag $variables and provide context for the inspection results.
- Search filter: easily find certain $variables by name and type.
- View up to 250 results. The free version is limited to 25 results.
- Individual and bulk deletion of results. Easily clean up your inspection dashboard from obsolete results you no longer need to reference. You can also select certain variables in bulk.

2.6.1 (2024.02.13)
- Disable certain viewers from inspecting variables of the object type as they can trigger fatal errors rendering the inspection dashboard unusable.
- [PRO] Added bulk select of inspection results, which allows for bulk selecting certain variable_names. Also added bulk deselect.
- [PRO] Fix dump_print_r output when text is truncated.
2.5.1 (2023.07.20)
- Fixed an issue where DB table creation failed when DB collation is empty/undefined for certain hosting / server set up.
2.5.0 (2023.07.05)

- [PRO] Feedback link in header no longer links to wordpress.org support forum. It now links to the contact form within wp-admin.
- [PRO] Fixed: space in vis() inspector’s second parameter no longer causes JS error and prevents variable content from loading. This is handled by converting space to underscore, e.g. ‚the variable‘ will show up as $the_variable in the inspection result accordion.
- [PRO] Fixed: special characters inside the ’notes‘ parameter in vi() and vis() inspectors are now handled better and won’t cause JS error.
- [PRO] Fixed: JS error „Maximum call stack size exceeded“ when performing ajax actions, e.g. generate sample results, refrehs, etc.
- [PRO] kint viewer: now will properly show $variable_name when getting the access path info of each node in the inspection result
- [PRO] Make the style of NULL results uniform across var_dump_r, var_dump_tree and kint viewers
