How can debugging techniques be used to identify errors in PHP scripts?

Debugging techniques like using print statements, var_dump(), or debugging tools like Xdebug can help identify errors in PHP scripts. By inserting these statements or tools at various points in the code, developers can track the flow of data and variables to pinpoint where issues may be occurring. Additionally, using error reporting functions like error_reporting(E_ALL) can help catch any errors that may not be immediately obvious. 

// Enable error reporting to catch all errors
error_reporting(E_ALL);

// Debugging with var_dump()
$variable = "Hello World";
var_dump($variable);

// Using print statements
echo "Debugging message";

// Utilizing Xdebug for more advanced debugging
// Xdebug is a PHP extension that provides debugging and profiling capabilities
