1. 在用mysql查询的时候，用group by (某一个字段) 将其查询结果合并；
或者；
2. 查询条件用limit 1 限制查询结果条数，反正内容一样，你就要一条即可；

array_unique函数提供了过滤重复的值的功能，但是该函数只能处理一维数组，如果遇到多维数组我们可以现将其转化为一维数组。示例代码如下

/*
* $data 是你要处理数据
* $result 是输出的结果
*/
//将其转化为一维数组
foreach ($data as $row) {
$row = serialize($row);
}
unset($row);
$data = array_unique($data);
//还原多维数组
foreach ($data as $row) {
$row = unserialize($row);
}
unset($row);
