PHP Version 7.1.18-1 on ubuntu16.04.1 xdebug is not working. How to enable it?

  • 772

I have installed php 7.1 in ubuntu 16.04 trough the following command:

sudo apt-get install -y software-properties-common
sudo add-apt-repository -y ppa:ondrej/php
sudo apt-get update
sudo apt-get install -y php7.1-fpm

After this step I just followed the instructions from Xdebug Tailored Installation Instructions as follow:

Summary
Xdebug installed: no
Server API: FPM/FastCGI
Windows: no
Zend Server: no
PHP Version: 7.1.18-1
Zend API nr: 320160303
PHP API nr: 20160303
Debug Build: no
Thread Safe Build: no
Configuration File Path: /etc/php/7.1/fpm
Configuration File: /etc/php/7.1/fpm/php.ini
Extensions directory: /usr/lib/php/20160303
Instructions
Download xdebug-2.6.0.tgz
Unpack the downloaded file with tar -xvzf xdebug-2.6.0.tgz
Run: cd xdebug-2.6.0
Run: phpize (See the FAQ if you don't have phpize.

As part of its output it should show:

Configuring for:
...
Zend Module Api No:      20160303
Zend Extension Api No:   320160303
If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.

Run: ./configure
Run: make
Run: cp modules/xdebug.so /usr/lib/php/20160303
Edit /etc/php/7.1/fpm/php.ini and add the line
zend_extension = /usr/lib/php/20160303/xdebug.so
Restart the webserver

After restarting the webserver (NGINX) I can't see the xdebug extention in the phpinfo() display:

enter image description here

This is my php.ini: /etc/php/7.1/fpm/php.ini

[xdebug]
zend_extension = /usr/lib/php/20160303/xdebug.so

Even xdebug 2.5.5 as suggested here in this post is not working, not even the Xdebug 2.7.0alpha1

php -v

    I had the same issue you as you. Despite having used the tailored instructions multiple times in the past, they don't seem to want to work on this particular configuration, and I can't tell exactly why.

    However, I had success installing it very simply using:

    sudo apt-get install php-xdebug
sudo service apache2 restart

    Don't know if you're still having the issue, but I hope it helps someone. Same issue from here: https://petersproblems.wordpress.com/
