How to debug PHP in eclipse
In this tutorial you will learn to debug PHP in eclipse IDE. We use XAMPP package installed on windows operating system to run PHP. Refer the previous tutorial How to Install PHP on Windows to prepare environment to run PHP.
Step 1: Install Xdebug for XAMPP
If the file C:\xampp\php\ext\php_xdebug.dll already exists, you can skip the download, Otherwise download Xdebug for the specific PHP version:
1. PHP 7.4 (64-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.4-vc15-x86_64.dll
2. PHP 7.4 (32-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.4-vc15.dll
3. PHP 7.3 (64-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.3-vc15-x86_64.dll
4. PHP 7.3 (32-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.3-vc15.dll
5. PHP 7.2 (32-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.2-vc15.dll
6. PHP 7.1 (32-Bit): https://xdebug.org/files/php_xdebug-2.9.7-7.1-vc14.dll

Move the downloaded dll file to: C:\xampp\php\ext
Open the file C:\xampp\php\php.ini with Notepad++
Disable output buffering: output_buffering = Off
Scroll down to the [XDebug] section (or create it) and copy/paste these lines:
[XDebug] zend_extension = "c:\xampp\php\ext\php_xdebug.dll" ;zend_extension = "c:\xampp\php\ext\php_xdebug-2.9.7-7.4-vc15-x86_64.dll" xdebug.remote_autostart = 1 xdebug.profiler_append = 0 xdebug.profiler_enable = 0 xdebug.profiler_enable_trigger = 0 xdebug.profiler_output_dir = "c:\xampp\tmp" ;xdebug.profiler_output_name = "cachegrind.out.%t-%s" xdebug.remote_enable = 1 xdebug.remote_handler = "dbgp" xdebug.remote_host = "127.0.0.1" xdebug.remote_log = "c:\xampp\tmp\xdebug.txt" xdebug.remote_port = 9000 xdebug.trace_output_dir = "c:\xampp\tmp" ;36000 = 10h xdebug.remote_cookie_expire_time = 36000 |

Click on Browse button and select the PHP executable php.exe from XAMPP installation. Click on Finish button.
After you click on Finish Button, you can see the added PHP executable and debugger Type. Now you click on Apply And Close.

Step 6: Check the debugger working
Add some debugger point on PHP file and make sure debugger is enabled.
Right click on index.php, select Run As>Run on Server.
Select PHP Built-in Server and click Finish
