Fixing cURL Issue with WAMP on Windows 7 64-Bit

Despite having WAMP installed and cURL enabled, users may encounter a common problem where cURL doesn't function due to an incorrect side-by-side configuration. This error message is often seen:

PHP Startup: unable to load dynamic library 'c:/wamp/bin/php/php5.4.3/ext/php_curl.dll' - the application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-lin sxstrace.exe tool for more detail.

To resolve this issue, it's crucial to download the appropriate cURL version that corresponds to the PHP version being used. Head over to https://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/ and locate the "Fixed curl extensions" section.

If running PHP 5.3.13, for instance, download and replace the existing php_curl.dll file in the ext folder with "php_curl-5.3.13-VC9-x64.zip" (VC version recommended initially). By replacing the dll file with the correct version, the cURL issue should be resolved, allowing it to function properly within the WAMP environment on Windows 7 64-bit.
