What are some strategies for debugging PHP code that generates HTML output?

One strategy for debugging PHP code that generates HTML output is to use var_dump() or print_r() functions to inspect variables and data structures. Another approach is to use error_reporting() function to display errors and warnings. Additionally, using an integrated development environment (IDE) with a debugger can help step through code execution and identify issues. 

<?php
// Enable error reporting to display errors and warnings
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Debugging variable values using var_dump()
$variable = "Hello World";
var_dump($variable);

// Debugging array values using print_r()
$array = array(1, 2, 3);
print_r($array);
?>
