PHP supports both scalar and associative arrays. In fact, there is no difference between the two. You can create an array using the array() function, or you can explicitly set each array element value.

$a[0] = "abc";
$a[1] = "def";
$b["foo"] = 13;
     

Arrays may be sorted using the sort(), ksort() and asort() functions depending on the type of sort you want.
