Errors in PHP's cURL: How to Detect and Handle Them

Catching errors while utilizing PHP's curl functions is crucial for ensuring reliable data transfer. Despite encountering errors like 404 or network failures, the provided code fails to recognize them:

if (curl_exec($c) === false) {
    echo "ok";
} else {
    echo "error";
}

Solution: Employing curl_error()

To effectively handle curl errors, you can utilize the curl_error() function. Here's a modified version of your code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FAILONERROR, true); // Report HTTP error codes
curl_exec($ch);

if (curl_errno($ch)) {
    $error_msg = curl_error($ch);
}
curl_close($ch);

if (isset($error_msg)) {
    // Handle the cURL error accordingly
}
