sort() returning '1'?

[smerny]

// $_POST['nums'] sample data could be "4,6,2,9,3"
$nums = sort(explode(',',$_POST['nums']),SORT_NUMERIC);
print_r($nums); //expect array with 2,3,4,6,9...instead got 1

 

 

why is the sort returning '1'?

sort doesn't return the sorted array, it returns a boolean indicating if it was successful or not. It takes the array by reference, so this how you would use it:

 

$arr = explode(',',$_POST['nums']);
sort($arr, SORT_NUMERIC);
print_r($arr);
