What potential pitfalls should be considered when buffering output in PHP for later use?

When buffering output in PHP for later use, it's important to consider potential pitfalls such as memory consumption and performance overhead. If too much output is buffered, it can lead to increased memory usage and slower processing times. To mitigate these risks, it's recommended to only buffer the necessary output and flush the buffer when it's no longer needed.

ob_start(); // Start output buffering

// Output buffering code here

$output = ob_get_clean(); // Get buffered output and clean buffer
echo $output; // Output buffered content
