What are some alternative methods to using output control functions for managing and processing generated content in PHP?

Using output control functions like ob_start() and ob_get_clean() can be useful for managing and processing generated content in PHP, but there are alternative methods that can achieve similar results. One alternative is to store the generated content in a variable and manipulate it as needed before outputting it. This can provide more flexibility and control over the content without relying on output control functions.

// Alternative method to manage and process generated content in PHP

// Generate content
$content = "Hello, World!";

// Manipulate content
$content = strtoupper($content);

// Output content
echo $content;
