 ## PHP (curl)
 
-TODO
+Here are the detailed instructions for running the generated API Dash code in PHP (using `curl`) for macOS, Windows, and Linux:
+
+### 1. Install and set PHP:
+Before starting out, we need to install PHP in our system. 
+#### macOS:
+- Go to the official PHP website: [https://www.php.net/manual/en/install.macosx.php](https://www.php.net/manual/en/install.macosx.php)
+- Follow the installation instructions.
+
+#### Windows:
+- Go to the official PHP website: [https://www.php.net/manual/en/install.windows.php](https://www.php.net/manual/en/install.windows.php)
+- Follow the installation instructions.
+
+#### Linux:
+The installation process depends on your Linux distribution. Use the appropriate command below:
+- ##### Ubuntu/Debian
+```bash
+sudo apt update
+sudo apt install php php-cli php-curl php-mbstring php-xml php-zip -y
+```
+- ##### Arch Linux / Manjaro
+```bash
+sudo pacman -S php php-apache php-cgi php-curl php-mbstring php-xml php-zip
+```
+- ##### Fedora / CentOS
+```bash
+- sudo dnf install php php-cli php-curl php-mbstring php-xml php-zip -y
+```
+- ##### OpenSUSE
+```bash
+sudo zypper install php php-cli php-curl php-mbstring php-xml php-zip
+```
+
+✅ Finally, check that everything works correctly pasting this command in your terminal
+```bash
+php --version
+```
+
+### 2. Check cURL
+cURL is usually enabled by default. To check if it's active, run:
+```bash
+php -m | grep curl
+```
+and check if it returns **curl** as output
+
+#### If curl is disabled
+
+ 1. Open the `php.ini` configuration file. You can find its location by running:
+```bash
+php --ini
+```
+ 2. Open the file in a text editor/IDE
+ 3. Find this line
+```bash
+;extension=curl
+```
+ 4. Remove the semicolon (`;`) at the beginning to enable it:
+```bash
+extension=curl
+```
+ 5. Save and restart php by using
+```bash
+sudo systemctl restart apache2  # For Apache
+sudo systemctl restart php8.2-fpm  # For PHP-FPM (Nginx)
+```
+
+### 3. Execute the generated code:
+Once you have everything needed installed, follow these steps to execute the generated code:
+
+1. **Open a IDE/text editor** ✍️ (Visual Studio, VS Code or any other text editor).
+2. **Create a php file ( ex. `request.php` )** ✍️ (Visual Studio, VS Code or any other text editor).
+3. **Copy and paste the generated API code** 📋 from API Dash into the `request.php` file.
+
+#### In Visual Studio:
+1. Click the **Start Debugging `(F5)`** button from the top menu to run the project.
+2. The terminal will display the API response.
+
+#### Using the CLI:
+ 1. Open the terminal at the project root directory and run the file you've created:
+   ```bash
+   php filename.php
+   ```
+ 2. The terminal will display the API response.
