What are some common issues when using cURL in PHP for external URLs?

One common issue when using cURL in PHP for external URLs is that the SSL certificate verification may fail, resulting in an error. To solve this, you can disable SSL verification by setting the CURLOPT_SSL_VERIFYPEER option to false in your cURL request. 

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification
$response = curl_exec($ch);
curl_close($ch);

if ($response === false) {
    echo 'cURL error: ' . curl_error($ch);
} else {
    echo $response;
}
