How can escaping characters in PHP prevent issues with outputting HTML code?

Escaping characters in PHP prevents issues with outputting HTML code by converting special characters into their HTML entity equivalents. This ensures that the HTML code is displayed correctly on the webpage without being interpreted as actual HTML tags or code. This can help prevent security vulnerabilities such as cross-site scripting attacks. 

<?php
$html_code = "<h1>Hello, World!</h1>";
echo htmlentities($html_code);
?>
