Question 57/69
What does the following code output?
```
<?php
$i = function ($j) {
   $i = $j + 4;
   $i++;
   return $i;
};
$j = 6;
echo $i($j);
?>
```
10

syntax error

nothing

11

6

In this script, we have an anonymous function. We declare it and assign it to $i. Then we call it, and pass in $j which is set to 6. The $i inside the scope of the function has no link with anything outside, so it's fine (although confusing!) to use the variable name there. 6 +4 is 10, then we increment $i and make 11, then return it.
