我正在寻找一种方法，用PHP将HTML表行存储到一个数组中，每个列值都是一个独特的数组值。
首先，我有一个完整的HTML页面，我从curl函数获得。在此页面中，我有一个具有特定ID（example_table）的表。
如何选择此表，然后将每个表值放入2坐标数组？
<table id="example_table">
<tr><td>A1</td><td>B1</td><td>C1</td><td>D1</td></tr>
<tr><td>A2</td><td>B2</td><td>C2</td><td>D2</td></tr>
<tr><td>A3</td><td>B3</td><td>C3</td><td>D3</td></tr>
</table>
生成的数组如下：
array_example[2][3] = D3
//编辑：
我从curl获得的HTML代码如下：
<table style="width: 95%; border-collapse: collapse" id="itemDetails">
<tbody>
<tr>

答案 0 :(得分：1)
您示例中的表格数据单元格除了某些空格外没有任何文本内容。它们具有带属性的子元素，但我想你想提取它们的数据。
使用DOM + Xpath。 DOM可以加载HTML（它将修复错误并可能改变结构）。 DOMXpath::evaluate()允许您从DOM中获取节点列表和标量值。 Xpath表达式用于处理DOM内的节点。
$document = new DOMDocument();
$document->loadHtml($html);
$xpath = new DOMXpath($document);
$result = [];
foreach($xpath->evaluate('//table[@id="itemDetails"]//table/tbody/tr') as $tr) {
$row = [];
foreach ($xpath->evaluate('td[a]', $tr) as $td) {
$row[] = [
'href' => $xpath->evaluate('string(a/@href)', $td),
'image' => $xpath->evaluate('string(a/img/@src)', $td),
'text' => $xpath->evaluate('string(a/img/@alt)', $td)
];
}
$result[] = $row;
}
var_dump($result);
输出：
array(1) {
[0]=>
array(3) {
[0]=>
array(3) {
["href"]=>
string(908) "https://www...."
["image"]=>
string(103) "http://g-ecx..."
["text"]=>
string(8) "Facebook"
}
[1]=>...
