What are common debugging techniques to identify issues in PHP scripts?

Issue: One common debugging technique to identify issues in PHP scripts is to use var_dump() or print_r() functions to display the contents of variables and arrays at various points in the code to see their values and structures. 

// Debugging using var_dump()
$variable = "Hello, World!";
var_dump($variable);
```

Another technique is to enable error reporting by setting error_reporting to E_ALL and display_errors to On in the php.ini file or using error_reporting(E_ALL) and ini_set('display_errors', 1) at the beginning of the script.

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

Additionally, using a debugger tool like Xdebug can help step through the code, set breakpoints, and inspect variables to identify issues more efficiently.

```php
// Using Xdebug debugger
xdebug_start_trace();
// Code to debug
xdebug_stop_trace();
