HTML 表到数组在 PHP 中的转换

Question

<table>
    <tr>
        <th>Alert ID</th>
        <td>1002522</td>
    </tr>
    <tr>
        <th>Client</th>
        <th>Tri-County Eye</th>
    </tr>
</table>

如何将 HTML 表格转换为 PHP 数组？

Answer 1

你必须在 php 中使用DOMElement

DOMElement::getElementsByTagName :-此函数返回具有给定标记名称的所有后代元素的类 DOMNodeList 的新实例，按照它们在此元素树的先序遍历中遇到的顺序。

<?php
$html = "<table><tr><td>Name</td><td>Aman</td></tr></table>";
$DOM = new DOMDocument;
$DOM->loadHTML($html);
$items = $DOM->getElementsByTagName('tr')->item(0);
echo "<pre>";
print_r($items);
?>

Answer 2

像这样排列你的表格数据

HTML

        <table>
            <tr>
                <th>Alert ID</th> <!-- for array key -->
                <td>1002522</td> <!-- for array value -->
            </tr>
            <tr>
                <th>Client</th>
                <td>Tri-County Eye</td>
            </tr>
        </table>

PHP

$html = "<table><tr><th>Alert ID</th><td>1002522</td></tr><tr><th>Client</th><td>Tri-County Eye</td></tr></table>";
        $DOM = new DOMDocument;
        $DOM->loadHTML($html);
        $items = $DOM->getElementsByTagName('tr');
        $array = [];
        foreach ($items as $key => $item) {
            foreach ($item->childNodes as $child) {
                if ($child->tagName === 'th') {
                    $array[$key][$child->nodeValue] = $child->nextSibling->nodeValue;
                }
            }
        }
        echo "<pre>";
        print_r($array);

输出

Array
(
    [0] => Array
        (
            [Alert ID] => 1002522
        )

    [1] => Array
        (
            [Client] => Tri-County Eye
        )

)
