Why does NetBeans show \"Waiting for connection (netbeans-xdebug)\" while debugging a project?

NetBeans displays "Waiting for connection (netbeans-xdebug)"

When debugging a project using NetBeans IDE, you may encounter "Waiting for connection (netbeans-xdebug)" Connect (netbeans-xdebug)" error message. To resolve this issue, follow these steps to configure xdebug:

Modify the php.ini file

In the php.ini file, make sure xdebug is active and have the following Settings:

[XDebug]
zend_extension = "<path_to_php_xdebug_extension>"
xdebug.remote_autostart=on
xdebug.remote_enable=on
xdebug.remote_enable=1
xdebug.remote_handler="dbgp"
xdebug.remote_host=<ip_address>
xdebug.remote_port=<port>
xdebug.remote_mode=req
xdebug.idekey="netbeans-xdebug"

Be sure to replace with the actual path to the xdebug extension, with your system IP address, and with the debugger port (usually 9000) .

Configuring NetBeans

In NetBeans IDE, go to Tools > Options > PHP > Debugging.

• Set the "Debugger Port" to match the port specified in php.ini.
• Set the "Session ID" to match the idekey in php.ini.

Restart Apache

Save the php.ini file and restart the Apache server.

Try debugging

Now, try debugging your project. If everything is configured correctly, NetBeans will be able to connect to xdebug and start debugging.
