How can include and require statements be used effectively in PHP to capture outputs into a variable?

When using include and require statements in PHP, you can capture the output into a variable by using output buffering. This allows you to store the output of an included file in a variable rather than directly outputting it to the browser. To achieve this, you can use ob_start() to turn on output buffering, include or require the file, and then use ob_get_clean() to retrieve the buffered output into a variable. 

ob_start();
include 'file.php';
$includedContent = ob_get_clean();
