What are some methods to intercept and store HTML content in PHP before it is outputted?

When working with HTML content in PHP, you may need to intercept and store the content before it is outputted to the browser for various reasons such as caching, manipulation, or logging. One common method to achieve this is by using output buffering in PHP. Output buffering allows you to capture the HTML output and store it in a variable before sending it to the browser. 

// Start output buffering
ob_start();

// Your HTML content goes here
echo "<html><body><h1>Hello, World!</h1></body></html>";

// Store the HTML content in a variable
$html_content = ob_get_clean();

// You can now manipulate or store the $html_content variable as needed
