What are some common debugging techniques in PHP to identify and fix issues in the code?

Issue: One common debugging technique in PHP is to use var_dump() or print_r() functions to display the contents of variables and arrays, helping identify the values and structure of data during execution. 

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

Issue: Another effective debugging technique is to use error_reporting() function to set the level of error reporting in PHP, which helps to identify and fix errors in the code by displaying warnings and notices.

```php
// Debugging using error_reporting()
error_reporting(E_ALL);
```

Issue: Utilizing the PHP built-in function debug_backtrace() can provide a trace of function calls leading up to a specific point in the code, aiding in understanding the flow of execution and identifying issues.

```php
// Debugging using debug_backtrace()
function testFunction() {
    var_dump(debug_backtrace());
}
testFunction();
