嗨我是php的新手，我的数组中包含一些常见数据，我尝试了很多代码，搜索的内容也越来越多，但我无法做到这一点请帮助我谢谢。

Array(

请帮帮我

最简单的方法是遍历数组并将unqiue对象保存到新数组中，例如：

$uniqueArray = array();
foreach($array as $object){
    if(!isset($uniqueArray[$object->user_id])){
        $uniqueArray[$object->user_id] = $object;
    }
}

评论后更新 您想要聚合一些数据，但结果数组仍然应该是每个user_id。因此，如果已经设置了具有user_id的对象，则将loop-part更改为concat：

$uniqueArray = array();
foreach($array as $object){
    if(!isset($uniqueArray[$object->user_id])){
        $uniqueArray[$object->user_id] = $object;
    }else{
        $uniqueArray[$object->user_id]->sender .= ',' . $object->sender;
    }
}

用示例测试：

<?php
