How to Configure Xdebug in Mac with XAMPP

 To install with single command:

pecl install xdebug

Or Follow the instructions below:

https://xdebug.org/wizard

Installation Wizard

Summary

• Xdebug installed: no
• Server API: Apache 2.0 Handler
• Windows: no
• Zend Server: no
• PHP Version: 8.2.4
• Zend API nr: 420220829
• PHP API nr: 20220829
• Debug Build: no
• Thread Safe Build: no
• OPcache Loaded: no
• Configuration File Path: /Applications/XAMPP/xamppfiles/etc
• Configuration File: /Applications/XAMPP/xamppfiles/etc/php.ini
• Extensions directory: /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20220829

Instructions

 

1. Download xdebug-3.2.2.tgz
2. Install the pre-requisites for compiling PHP extensions.
   On your Mac, we only support installations with 'homebrew', and brew install php && brew install autoconf should pull in the right packages.
3. Unpack the downloaded file with tar -xvzf xdebug-3.2.2.tgz
4. Run: cd xdebug-3.2.2

5. 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:      20220829
   Zend Extension Api No:   420220829

   If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.

6. Run: ./configure
7. Run: make
8. Run: cp modules/xdebug.so /Applications/XAMPP/xamppfiles/lib/php/extensions/no-debug-non-zts-20220829
9. Update /Applications/XAMPP/xamppfiles/etc/php.ini and add the line:
   zend_extension = xdebug
10. Restart the Apache Webserver

Enabling Features

Now Xdebug is installed, you can enable its features. Please refer to the dedicated sections in the documentation about information on how to enable and configure these Xdebug features. Where these sections refer to php.ini or similar, please remember to use /Applications/XAMPP/xamppfiles/etc/php.ini:

• Development Helpers — help you get better error messages and obtain better information from PHP's built-in functions.
• Step Debugging — allows you to interactively walk through your code to debug control flow and examine data structures.
• Profiling — allows you to find bottlenecks in your script and visualize those with an external tool.

Installing PHP 8.1 to Add PHP support to Nginx on Ubuntu

 Install PHP for Nginx with PHP-FPM:

sudo apt update

sudo apt install --no-install-recommends php8.1 [Apache HTTP server and its httpd process]

sudo apt-get install php8.1-fpm -y [For PHP-FPM works with nginx]

php -v

sudo apt-get install -y php8.1-cli php8.1-common php8.1-mysql php8.1-zip php8.1-gd php8.1-mbstring php8.1-curl php8.1-xml php8.1-bcmath php8.1-imap

php -m

Check if PHP-FPM is running:

sudo systemctl status php8.1-fpm

Add PHP support to Nginx:

sudo nano /etc/nginx/sites-available/default

Enable PHP in Nginx’s config file:

server {

  # Example PHP Nginx FPM config file

  listen 80 default_server;

  listen [::]:80 default_server;

  root /var/www/html;

  # Add index.php to setup Nginx, PHP & PHP-FPM config

  index index.php index.html index.htm index.nginx-debian.html;

  server_name _;

  location / {

    try_files $uri $uri/ =404;

  }

  # pass PHP scripts on Nginx to FastCGI (PHP-FPM) server

  location ~ \.php$ {

    include snippets/fastcgi-php.conf;

    # Nginx php-fpm sock config:

    fastcgi_pass unix:/run/php/php8.1-fpm.sock;

    # Nginx php-cgi config :

    # Nginx PHP fastcgi_pass 127.0.0.1:9000;

  }

  # deny access to Apache .htaccess on Nginx with PHP, 

  # if Apache and Nginx document roots concur

  location ~ /\.ht {

    deny all;

  }

} # End of PHP FPM Nginx config example

sudo nginx -t

sudo systemctl restart nginx

Install multiple PHP version on Ubuntu for Virtualmin

 Enable ondrej/php repository

LC_ALL=C.UTF-8 add-apt-repository -y ppa:ondrej/php && apt-get update

Install additional PHP packages

apt-get install php*-{cgi,cli,fpm,pdo,gd,mbstring,mysqlnd,opcache,xml,zip} 

Note: php* should be replaced with a specific PHP version, i.e. php7.4, unless you really need to install all available additional PHP versions.

Configuring the second PHP Version in Virtualmin

Once you have completed the installation of a second PHP version on your server, you can verify that Virtualmin sees it by logging into Virtualmin, and clicking System Settings → Re-Check Config. You should see something like this:

The following PHP execution modes are available : fpm
The following PHP-FPM versions are available : 8.0.13 (php-fpm) 7.4.30 (php74-php-fpm) 8.2.0 (php82-php-fpm) 

You can configure which one is the default PHP version used on new Virtual Servers. The default is to use the newest available. You can change that default in System Settings → Server Templates → Default → PHP Options page.

Configuring Individual Virtual Servers

You can configure the PHP version being used for a specific Virtual Server by selecting Server Configuration → PHP Options.
