What are some methods in PHP to call another script and redirect the output as a string?

When you need to call another PHP script and capture its output as a string, you can use functions like `file_get_contents()` or `curl` to fetch the output of the script. Alternatively, you can use output buffering with functions like `ob_start()` and `ob_get_clean()` to capture the output generated by the script. 

// Using file_get_contents()
$output = file_get_contents('http://example.com/another_script.php');

// Using cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/another_script.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

// Using output buffering
ob_start();
include 'another_script.php';
$output = ob_get_clean();
