How can the order of PHP functions impact the output when manipulating HTML content?

The order of PHP functions can impact the output when manipulating HTML content because functions are executed sequentially, and the output of one function may be used as input for another. To ensure the desired output, it's important to consider the order in which functions are called when manipulating HTML content.

<?php
// Example of manipulating HTML content with PHP functions in a specific order
$html = "<div><p>Hello, World!</p></div>";

// Step 1: Remove the <p> tags
$html = strip_tags($html);

// Step 2: Convert the text to uppercase
$html = strtoupper($html);

// Step 3: Output the modified HTML
echo $html;
?>
