How to set the maximum number of redirects to follow in a cURL request in PHP?

To set the maximum number of redirects to follow in a cURL request in PHP, you can use the CURLOPT_FOLLOWLOCATION and CURLOPT_MAXREDIRS options in conjunction.

Here's an example of how you can do it:

// Initialize cURL
$ch = curl_init();

// Set the URL
$url = "http://example.com";
curl_setopt($ch, CURLOPT_URL, $url);

// Enable automatic following of redirects
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

// Set the maximum number of redirects to follow
curl_setopt($ch, CURLOPT_MAXREDIRS, 5); // Change 5 to your desired maximum

// Other cURL options if needed...

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

// Check for errors
if (curl_errno($ch)) {
    echo 'cURL Error: ' . curl_error($ch);
}

// Close cURL
curl_close($ch);

In this example, we set CURLOPT_FOLLOWLOCATION to true to allow cURL to automatically follow any redirects encountered. Then, we set CURLOPT_MAXREDIRS to 5 to specify the maximum number of redirects to follow. You can change the 5 to your desired maximum number.

Finally, you can add other cURL options if needed for your specific request. Remember to check for errors using curl_errno and close the cURL session with curl_close.
