How to use Xdebug to speed up PHP development

By using the Xdebug PHP extension, you can speed up PHP development by following these steps: Install and configure the Xdebug extension. Set Xdebug options in the integrated development environment (IDE). Use -d xdebug.remote_autostart=1 to enable Xdebug autostart for debugging scripts. Use -d xdebug.profiler_enable=1 to enable the Xdebug profiler to profile performance.

How to use Xdebug to accelerate PHP development

Xdebug is a PHP extension that improves development efficiency by providing debugging and performance analysis tools. This article will guide you through installing, configuring, and using Xdebug to speed up PHP development.

Installation

Ubuntu/Debian:

sudo apt-get install php-xdebug

MacOS:

brew install php-xdebug

Windows ( Run as administrator):

Download and install the Xdebug Windows binaries from https://xdebug.org/wizard.php.

Configuration

Edit your php.ini file and add the following line:

zend_extension="/path/to/xdebug.so"
xdebug.remote_enable=on
xdebug.remote_port=9000
xdebug.remote_autostart=off

Restart the Apache or PHP-FPM service to apply the changes.

Using the Integrated Development Environment (IDE)

PhpStorm:

##Open "Settings" (Preferences).
Go to "PHP" > "Debug".
In the "Xdebug" tab, enter the Xdebug remote port (9000).
Click "Apply".

Visual Studio Code:

Install the Xdebug debugging extension.
Open "Settings".
Go to "Extensions".
Search for "Xdebug" and enter the port (9000).
Click "Apply".

Practical case

Debug script

Use the

-d xdebug.remote_autostart=1 option to enable Xdebug auto-start:

php -d xdebug.remote_autostart=1 script.php

Launch your IDE, add breakpoints to the script, and run the script. Once a breakpoint is reached, the IDE will automatically connect to the Xdebug server and allow you to debug your code.

Analyze performance

Use the

-d xdebug.profiler_enable=1 option to enable the Xdebug profiler:

php -d xdebug.profiler_enable=1 script.php

After the script is run, a cachegrind will be generated File (usually named

cachegrind.out.[num]) that contains detailed performance data about the execution of the script. You can visualize and analyze this data using an IDE or third-party tools such as KCacheGrind.

Conclusion

Using Xdebug to speed up PHP development can save a lot of time and effort. With debugging and profiling capabilities, you can quickly identify and resolve errors, optimize code performance, and improve the overall quality of your project.
