What are common debugging techniques for PHP code?

One common debugging technique for PHP code is to use var_dump() or print_r() to display the contents of variables and arrays at various points in your code to check their values. Another technique is to enable error reporting and display errors to help identify syntax errors or runtime issues. Additionally, using a debugger tool like Xdebug can help step through your code line by line and track variable values. 

// Using var_dump() to display the contents of a variable
$variable = "Hello, World!";
var_dump($variable);

// Enabling error reporting to display errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Using Xdebug to debug code
// Install Xdebug extension and configure your IDE for debugging
