Getting Started with Drupal Development Tools, 2.2: How to Print PHP Variables using Devel in Drupal

If you're looking for a quick and easy way to inspect variables in PHP, consider using the dpm() function, a handy tool the Devel module provides.

While tools like Xdebug are excellent for large projects, a quick and simple solution is sometimes necessary.

The dpm() function allows developers to print variables in a readable format directly on the page.

This can be particularly useful for quick debugging and inspecting data structures without setting up complex environments.

To use the DPM function:

1️⃣Enable the Devel module in your Drupal installation

2️⃣Turn off caching in your development environment by going to Configuration "Development settings"

3️⃣Insert dpm($variables) in your code where you want to inspect variables

4️⃣Refresh the page to see the output

The dpm() function is useful for quick debugging, but it shouldn't replace more advanced tools like Xdebug, which are essential for efficient Drupal development.

Remove or comment out dpm() calls before production for improved performance and security.
