上午刚需要的一个功能,在手册上找到了一个函数,但是不是我想要的结果
最后改了改实现了,拿来分享下。//函数功能:消除数组重复项,并且让键值重新从0开始排列<br>
function array_unrepeat($input){<br>
$input = array_unique($input);<br>
$keys = array();<br>
for($i=0;$i<count></count>
$keys[$i] = $i;<br>
}<br>
return array_combine($keys, $input);<br>
}<br>
//用法示例: <br>
//$input = array(0,0,1,1,2,2,3,3,4,4,7,7);<br>
//var_dump(array_unrepeat($input));<br>
//输出<br>
//array (size=6)<br>
// 0 => int 0<br>
// 1 => int 1<br>
// 2 => int 2<br>
// 3 => int 3<br>
// 4 => int 4<br>
// 5 => int 7
------------------------------
Update:
从广大网友那里得到的更简单的方法:
$result = array_values(array_unique ($input));
$result = array_keys(array_flip($input));
