Are there any limitations on the return value when using cURL to access a PHP script?

When using cURL to access a PHP script, there are no inherent limitations on the return value. However, it's important to ensure that the PHP script being accessed returns the desired data in a format that can be easily processed by the cURL request. This can include returning data in JSON or XML format for easier parsing. 

<?php
$url = 'http://example.com/api/script.php';
$ch = curl_init($url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

if($response === false){
    echo 'cURL error: ' . curl_error($ch);
} else {
    // Process the response data here
    echo $response;
}

curl_close($ch);
?>
