Here's a simple PHP script that swaps the values of two variables:
```php
$num1 = 10;
$num2 = 20;
// Swap the values
$temp = $num1;
$num1 = $num2;
$num2 = $temp;
echo "Num1: {$num1}n";
echo "Num2: {$num2}";
```
This script first stores the value of `$num1` in a temporary variable, then assigns the value of `$num2` to `$num1`, and finally assigns the value of the temporary variable (previously containing `$num1`) to `$num2`. The final output will be:
```
Num1: 20
Num2: 10
```
