Are there any specific PHP functions or techniques that can help ensure consistent layout and display of data on a webpage?

To ensure consistent layout and display of data on a webpage, you can use PHP functions like `echo` to output HTML code with consistent formatting. You can also use CSS classes to style elements consistently across your webpage. Additionally, you can use PHP functions like `sprintf` to format data in a consistent manner before displaying it on the webpage.

<?php
// Example of using PHP echo to output HTML with consistent formatting
echo '<div class="content">Hello, World!</div>';

// Example of using CSS classes to style elements consistently
echo '<div class="content">Hello, World!</div>';

// Example of using sprintf to format data before displaying it
$name = 'John';
$age = 30;
echo sprintf('Name: %s, Age: %d', $name, $age);
?>
