Why Is My PHP Script Failing to Execute When Calling cURL Despite Enabling the cURL Extension?

How to Install cURL on Windows

Issue:

Despite following all the necessary instructions, the PHP script still fails to execute when curl is called, returning an error that the curl_version() function is undefined. The phpinfo() function confirms that the cURL extension is enabled.

Resolution:

To install cURL on Windows, follow these steps:

1. Visit the cURL download page at https://curl.haxx.se/dlwiz?type=bin.
2. Select your operating system (Windows 32 or 64-bit) and click "Select!".
3. Choose the appropriate terminal type (Windows Command Prompt or Cygwin/MinGW) and click "Select!".
4. If necessary, choose your Windows operating system and click "Finish".
5. Click "Download" for the SSL-enabled or disabled version.
6. Extract the downloaded zip file to an easily accessible location, such as C:Program Files.

Testing cURL:

1. Open a Windows Command Prompt terminal (Run > cmd).
2. Set the path to include the directory where curl.exe is located (e.g., "set path=%path%;c:Program Filescurl").
3. Type "curl". If curl is successfully installed and the path is correct, you should see the following message: "curl: try 'curl –help' or 'curl –message' for more information".

Additional Notes:

• Ensure that the correct PHP.exe version is being used by the Apache server.
• Verify that the PHP.ini file contains the correct extension_dir and extension=php_curl.dll settings.

XAMPP Installation (Optional):

If you encounter persistent issues, consider installing XAMPP, a pre-configured web server suite that includes cURL and other essential components for PHP development on Windows. For more information, visit https://www.apachefriends.org/index.html.
