What are some common debugging techniques for identifying errors in PHP scripts?

One common debugging technique for identifying errors in PHP scripts is to use error reporting functions like error_reporting() and ini_set('display_errors', 1) to display error messages. Another technique is to use var_dump() or print_r() functions to inspect variables and their values during runtime. Additionally, using die() or exit() statements at strategic points in the code can help pinpoint where the script is failing. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Code snippet with var_dump() to inspect variable values
$variable = "Hello World";
var_dump($variable);

// Code snippet with die() to stop script execution
$number = 10;
if ($number > 5) {
    die("Number is greater than 5");
}
?>
