How can proper debugging techniques be applied to identify and resolve issues in PHP code?

Issue: To identify and resolve issues in PHP code, proper debugging techniques can be applied by using tools like Xdebug, printing out variables and messages at key points in the code, and utilizing error reporting functions like error_reporting() and ini_set('display_errors', 1). PHP Code Snippet: 

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

// Debug using print statements
$variable = "Hello";
echo "Debug: Variable value is " . $variable;

// Use Xdebug for more advanced debugging
// Example: xdebug_break();
