NetBeans 8: Waiting For Connection (netbeans-xdebug)

Xdebug is a debugging tool for PHP that allows developers to step through their code and inspect variables during execution. This article will guide you through configuring Xdebug for use with NetBeans 8 to debug your PHP projects.

Prerequisites:

• PHP 5.4.16 or later
• NetBeans 8 or later
• XAMPP 1.8.2 or later with Apache 2.4.4

Problem:

After configuring Xdebug in the php.ini file, NetBeans displays the "Waiting For Connection (netbeans-xdebug)" message during debugging.

Solution:

1. Edit php.ini:

Open the php.ini file in your XAMPP installation directory and add the following lines:

zend_extension = "C:\xampp\php\ext\php_xdebug-2.2.3-5.4-vc9-nts.dll"
xdebug.remote_enable = 1
xdebug.remote_handler = "dbgp"
xdebug.remote_mode = req
xdebug.remote_host = "127.0.0.1"
xdebug.remote_port = 9000
xdebug.idekey = "netbeans-xdebug"

2. Restart Apache:

Restart Apache to apply the changes to your php.ini file.

3. Configure NetBeans:

Open NetBeans and navigate to Tools > Options > PHP > Debugging. Set the following options:

• Debugger Port: 9000
• Session ID: netbeans-xdebug

4. Test the Configuration:

Create a new PHP project in NetBeans and include the following code in your main script:

<?php
$x = 1;
$y = 2;
var_dump($x + $y);
?>

Set a breakpoint on the var_dump line and start debugging. If the debugging session starts and you can step through the code, the Xdebug configuration is successful.
