从PHP中的foreach循环返回不同的值? [英] Returning distinct values from foreach loop in PHP?

问题描述

我有一个foreach循环，该循环在搜索结果中每个echo属性类型.代码如下:

I have a foreach loop which echo's each of the property types in my search results. The code is as follows:

<?php 
    foreach($search_results as $filter_result) {
        echo $filter_result['property_type'];
    } 
?>

上面的代码返回:

house house house house flat flat flat

我想做些类似于MySQL'distinct'的事情，但是我不确定如何在foreach语句上做到这一点.

I would like to do something similar to the MySQL 'distinct', but I am not sure how to do it on a foreach statement.

我希望上面的代码返回:

I want the above code to return:

• 房子
• 平

不每次都重复每个项目.我该怎么办?

Not repeat every item each time. How can I do this?

推荐答案

尝试使用:

$property_types = array();
foreach($search_results_unique as $filter_result){
    if ( in_array($filter_result['property_type'], $property_types) ) {
        continue;
    }
    $property_types[] = $filter_result['property_type'];
    echo $filter_result['property_type'];
}
