How can one check if the curl extension is installed and enabled in PHP?
To check if the curl extension is installed and enabled in PHP, you can use the `extension_loaded()` function to see if the curl extension is loaded. If it is not loaded, you can enable it in your PHP configuration file (php.ini) by uncommenting the line `extension=curl`.
// Check if the curl extension is loaded
if (!extension_loaded('curl')) {
echo 'The curl extension is not enabled.';
} else {
echo 'The curl extension is enabled.';
}
