问题描述

假设我有一个名称数组，我想要的是我想针对字符串或正则表达式搜索此特定数组，然后将找到的匹配项存储在另一个数组中。这可能吗 ？如果是，那么您能给我提示吗？我是编程新手。

推荐答案

您需要di的方法是使用如下回调函数映射数组：

what you would need to di is map the array with a callback like so:

array_filter($myarray,"CheckMatches");

function CheckMatches($key,$val)
{
    if(preg_match("...",$val,$match))
    {
        return $match[2];
    }
}

这将为数组中的每个元素运行回调！

This will run the callback for every element in the array!

已更新为 array_filter
