以数字开头的重复数据如:

复制代码 代码如下:


Array (
[0] => 100
[k1] => 100
[1] => 2123
[k2] => 2123  ) 


该方法可以将以数字为key的值去掉,先将数组按照key倒序排序,然后用array_unique的方法将重复的值去掉。
不能适用于下面的情况:不同的key值存在相同的value的情况

复制代码 代码如下:


function array_unique_value($arr = array()){ 
    array_multisort($arr, SORT_DESC, array_keys($arr)); 
    print_r(array_unique($arr)); 
}
