PHP数组函数array_unique对二维数组的处理

function unique($data = array()){        $tmp = array();        foreach($data as $key => $html' target='_blank'>value){                //把一维数组键值与键名组合                foreach($value as $key1 => $value1){                        $value[$key1] = $key1 . '_|_' . $value1;//_|_分隔符复杂点以免冲突                }                $tmp[$key] = implode(',|,', $value);//,|,分隔符复杂点以免冲突        }        //对降维后的数组去重复处理        $tmp = array_unique($tmp);        //重组二维数组  www.it165.net        $newArr = array();        foreach($tmp as $k => $tmp_v){                $tmp_v2 = explode(',|,', $tmp_v);                foreach($tmp_v2 as $k2 => $v2){                        $v2 = explode('_|_', $v2);                        $tmp_v3[$v2[0]] = $v2[1];                }                $newArr[$k] = $tmp_v3;        }        return $newArr;}$data = array(        array('id'=>1, 'title'=>'元芳', 'score'=>10),        array('id'=>2, 'title'=>'元芳,你怎么看', 'score'=>10),        array('id'=>3, 'title'=>'大人说：元芳，你怎么看', 'score'=>9),        array('id'=>1, 'title'=>'元芳', 'score'=>10),);$newArr = unique($data);//去重复后的二维数组Array(    [0] => Array        (            [id] => 1            [title] => 元芳            [score] => 10        )    [1] => Array        (            [id] => 2            [title] => 元芳,你怎么看            [score] => 10        )    [2] => Array        (            [id] => 3            [title] => 大人说：元芳，你怎么看            [score] => 9        ))
