What are some effective ways to troubleshoot PHP code that is not functioning as expected?

Issue: PHP code is not functioning as expected due to syntax errors or logical errors. Solution: To troubleshoot PHP code that is not functioning as expected, start by checking for syntax errors such as missing semicolons, parentheses, or curly braces. Next, use debugging tools like var_dump() or print_r() to inspect variables and their values to identify logical errors. Additionally, enable error reporting to display any errors or warnings that may be occurring in the code. 

<?php
// Check for syntax errors
if ($condition) {
    // Code block
}

// Use var_dump() to inspect variables
$variable = 'value';
var_dump($variable);

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