复制代码代码如下:function arrange($arr){$new_arr = array();$c = count($arr);foreach($arr as $key=>$vo){$lin = $arr;array_splice($lin,$key,1);for($l=0;$l $larr = array();$larr[] = $lin[$l];$larr[] = $vo;$larr[] = $vo;$new_arr[] = $larr;}}return $new_arr;}$arr = array(1,2,3,4);$r = arrange($arr);print_r($r);
得到的结果是：
