切换 PHP 数组的行和列

Question

我有一个用数组填充的数组。主数组中的每个数组都包含从房地产网站抓取的数据。当我将它们输出到 CSV 文件时，我想让每个数据类别（价格、地址、大小等）都有自己的单独列。现在，每个类别都存储在一行中。我在这里查看了一些关于此的线程，但无法使代码正常工作。我认为这是因为这个数组不包含字符串，它包含每个都包含字符串的数组。我想知道如何做到这一点。我尝试做 array_flip() 但是它返回一个错误，说数组必须包含字符串或数字。

这是我现在拥有的：

<?php

试一试。我无法测试它，因为我没有任何数据可以测试它。

如果您获取的数据中有空字段，您可能会遇到此方法的问题。

如果这不能解决您的问题，输出数据的图像会很棒。如果我可以处理一些数据，那就更好了。

PHP：

    <?php

    //URL HERE 
    $html = file_get_contents("URL_HERE");   
    $DOM = new DOMDocument();
    libxml_use_internal_errors(true);
    $DOM->loadHTML($html);


    // price
    $pfinder = new DomXPath($DOM);
    $classname_p = 'price-large';
    $pnodes = $pfinder->query("//*[contains(@class, '$classname_p')]");

    // zestimate
    $zfinder = new DomXPath($DOM);
    $classname_z = 'zestimate';
    $znodes = $zfinder->query("//*[contains(@class, '$classname_z')]");

    // address
    $afinder = new DomXPath($DOM);
    $classname_a = 'property-address';
    $anodes = $afinder->query("//*[contains(@class, '$classname_a')]");
