How do you want to sort array?  By key or by elements
First add array
$newval = array (2331, 232322,3434343);
array_push ($newval ,312126);  // we are adding four more elements to the array 

Open in new window

Now Choose your sorting option:
asort(); //elements sort ascending
arsort(); //elements sort descending;
ksort();//by  key sort ascending;
krsort(); //by key sort descending;

Open in new window
