How can effective debugging techniques be used to identify and fix errors in PHP code?

Effective debugging techniques can be used to identify and fix errors in PHP code by utilizing tools like error reporting, logging, and step-by-step debugging. Error reporting can help pinpoint the location and type of error in the code, while logging allows developers to track the flow of the program and identify potential issues. Step-by-step debugging enables developers to execute the code line by line, making it easier to identify and fix errors in the code. 

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

// Use logging to track program flow
error_log("Starting script");

// Step-by-step debugging
$var1 = 10;
$var2 = 0;

$result = $var1 / $var2;
echo $result;
?>
