How to handle cURL errors and exceptions in PHP?

In PHP, you can handle cURL errors and exceptions using try-catch blocks. Here's an example of how you can handle cURL errors and exceptions:

try {
    // Initialize cURL session
    $ch = curl_init();

    // Set cURL options, e.g., URL and other parameters

    // Execute cURL request
    $response = curl_exec($ch);

    // Check for cURL errors
    if(curl_errno($ch)){
        throw new Exception(curl_error($ch));
    }

    // Process the response

    // Close cURL session
    curl_close($ch);
} catch (Exception $e) {
    // Handle the exception, e.g., log the error or show an error message
    echo "cURL Error: " . $e->getMessage();
}

In the above example, the curl_exec() function is used to execute the cURL request. After that, curl_errno($ch) is used to check if there is any error occurred during the execution of the request. If an error occurs, curl_error($ch) returns the error message, and an Exception is thrown with that error message.

The catch block will catch the exception and you can handle it accordingly, such as logging the error or displaying an error message to the user.

Remember to always close the cURL session using curl_close($ch) to free up resources and prevent any memory leaks.
