How can one effectively debug PHP code without a dedicated debugging program?

To effectively debug PHP code without a dedicated debugging program, you can use techniques such as inserting echo statements to output variable values, utilizing error_reporting to display errors, and using var_dump or print_r to inspect data structures. By strategically placing these debugging tools throughout your code, you can identify and resolve issues effectively. 

<?php
// Example PHP code snippet with debugging techniques
error_reporting(E_ALL);
ini_set('display_errors', 1);

$variable = "Hello, World!";
echo $variable;

$number = 10;
echo "The number is: " . $number;

$array = [1, 2, 3];
var_dump($array);
?>
