PHP cURL Not Functioning on Windows 7 64-bit: Troubleshooting WAMP

PHP cURL is a powerful tool that allows PHP scripts to transfer data over the internet. However, if you're experiencing issues with cURL on a WAMP server running on Windows 7 64-bit, it can be frustrating.

Common Issues and Solution

One of the most common problems is the inability to load the cURL extension. To resolve this:

1. Ensure cURL is enabled in the WAMP tray.
2. Uncomment extension=php_curl.dll in the php.ini file for both PHP and Apache folders.

Error: "Unable to Load Dynamic Library"

If you encounter an error stating that "the application has failed to start because its side-by-side configuration is incorrect," follow these steps:

1. Download the correct cURL version for your PHP version from http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/.
2. Look for the "Fixed curl extensions" section.
3. For PHP 5.3.13, download "php_curl-5.3.13-VC9-x64.zip."
4. Replace the existing php_curl.dll file in the ext folder with the downloaded one.
