What is the best way to execute a PHP file and capture all outputs into a variable?

When executing a PHP file and capturing all outputs into a variable, you can use output buffering in PHP. This allows you to capture all outputs, including any errors or warnings, into a variable for further processing or logging. By using the ob_start() function to start output buffering before including the PHP file and then using ob_get_clean() to retrieve the buffered output into a variable, you can easily capture all outputs. 

ob_start();
include 'your_php_file.php';
$output = ob_get_clean();
