Function formatArray ($ array)
{
Sort ($ array );
$ Tem = "";
$ Temarray = array ();
$ J = 0;
For ($ I = 0; $ I {
If ($ array [$ I]! = $ Tem)
{
$ Temarray [$ j] = $ array [$ I];
$ J ++;
}
$ Tem = $ array [$ I];
}
Return $ temarray;
}

$ Array = array ('A', 'BB ', 'AA', 3,4, 5, 5, 5, 'BC ');

Print_r ($ arr );
