How can PHP developers effectively troubleshoot and debug issues like unexpected variables or syntax errors in their code?

To troubleshoot and debug unexpected variables or syntax errors in PHP code, developers can utilize tools like error reporting, var_dump(), and using an IDE with built-in debugging capabilities. By enabling error reporting and checking for syntax errors, developers can quickly identify and fix any issues in their code. 

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

// Check for syntax errors
if (ini_get('display_errors')) {
    ini_set('display_errors', 'stderr');
}

// Use var_dump() to print out variables
$variable = 'Hello World';
var_dump($variable);
?>
