How can the use of echo structures in PHP scripts impact the display of results in the browser?

Using excessive echo structures in PHP scripts can clutter the output and make it difficult to read and debug. To improve the display of results in the browser, it is recommended to use proper HTML structure and formatting along with echoing only necessary information.

<?php
// Example of using proper HTML structure to improve display of results
echo "<html>";
echo "<head><title>Results</title></head>";
echo "<body>";
echo "<h1>Results:</h1>";
echo "<p>This is the result of the PHP script.</p>";
echo "</body>";
echo "</html>";
?>
