{
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;
}
//测试 调用函数
$array = array('aa','bb','aa',3,4,5,5,5,5,'bc');
$arr = formatArray($array);

Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
