Is it possible to use xdebug on Ubuntu?

I am trying to debug some PHP code and wanted to download the XDebug debugger for PHP. All I see there is Windows binaries for downloading. Is it at all possible to use it on Ubuntu?

Execute the following commands in your terminal.

Download Xdebug - you will need to follow alternate instructions if you don't have PHP5 working on your machine already.

sudo apt-get install php5-xdebug

The package should modify your INI file for you, but just in case you need to edit it yourself open it up and make the following modification - on Ubuntu its typically at /etc/php5/apache2/php.ini - add the following line.

zend_extension="/usr/lib/php5/20110331/xdebug.so"

That path might be a little different on your system - just make sure its a fully qualified path to the xdebug.so file on your machine. Also remember to comment out any references to the Zend Debugger - you can't run both at the same time.

Now restart Apache.

sudo /etc/init.d/apache2 restart

You may also need want enable html_errors. Search for html_errors in /etc/php5/apache2/php.ini and make sure it is set to On. A restart of Apache is also required.

html_errors = On

Double-check with phpinfo() to make sure that everything is installed properly - you may also want to set configurations for Xdebug in your php.ini file.

sudo apt-get install php5-xdebug

On a newer Ubuntu (at least on 14.04 LTS), I needed to activate the module as well. So, in total I did:

sudo apt-get install php5-xdebug
sudo php5enmod xdebug

After a restart of the server, xdebug was available.

This article was what helped me in Ubuntu 16.04 running PHP7:

sudo apt-get install php-xdebug

::ubuntu 18.04, php7.2, apache2:: 1. First install xdebug using sudo apt-get install php-xdebug. 2. This will create file /etc/php/7.2/mods-available/xdebug.ini 3. You can run sudo phpenmod xdebug 4. open xdebug.ini using sudo nano /etc/php/7.2/mods-available/xdebug.ini 5. you can see only the line: zend_extension=xdebug.so 6. assuming running php apache on localhost and netbeans IDE, add following line to xdebug.ini

xdebug.show_error_trace = 1
xdebug.idekey=netbeans-xdebug
xdebug.default_enable=1
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.remote_autostart=1

N.B: xdebug.idekey and xdebug.remote_port can be obtained from netbeans tools->optins->php->debug

Proper way to install XDEBUG for newest version of LAMPP:

Download: XDEBUG latest version called source.
Extract file to any folder.
Open this folder with terminal.
Change X.X.X to Your actually version of php

Execute the following commands in your terminal.

/opt/lampp/bin/phpize-X.X.X
./configure --with-php-config=/opt/lampp/bin/php-config-X.X.X
make
cp modules/xdebug.so /opt/lampp/lib/php/extensions/no-debug-non-zts-20170718

Now we need edit file php.ini

Open folder where is file php.ini in terminal:
```
sudo nano ./php.ini
```

Add to the end of file this:

zend_extension = /opt/lampp/lib/php/extensions/no-debug-non-zts-20170718/xdebug.so

Open LAMPP folder in terminal
Now restart Apache.
```
sudo ./xampp restart
```

And now You can check phpinfo() to see XDEBUG is installed.

Try compiling from source, that's what I do on my mac.
