How can debugging techniques help identify errors in PHP code?

Debugging techniques such as using var_dump(), print_r(), and error_reporting can help identify errors in PHP code by providing insight into the values of variables, the execution flow of the code, and any error messages that may occur. By using these techniques, developers can pinpoint the exact location of an error and troubleshoot it effectively. 

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

$var1 = 5;
$var2 = "10";

$result = $var1 + $var2; // This will result in a type mismatch error

var_dump($result); // Use var_dump() to display the value of $result
?>
