我需要將鏈接和鏈接標籤分爲兩個單獨的數組。我跟着幾個論壇，並做了一個代碼，但是出現錯誤。我不知道在代碼中使用的查找功能錯誤的第14行，PHP捲曲DOM

請修復您的代碼格式併發布錯誤。 – 2010-07-02 02:20:09

幾個問題，主要是對不存在的函數的調用和對不存在的屬性的引用。正確版本：

<?php 
$var = <<<EOD 
<html> 
<a href="sdfgs">sdfd</a> 
</html> 
EOD; 

$dom = new DOMDocument(); 
@$dom->loadHTML($var); 
$xpath = new DOMXPath($dom); 

foreach($xpath->query('//a') as $element) { 
    $linklabel[] = $element->textContent; 
    $link[] = $element->getAttribute("href"); 
} 
var_dump($linklabel); 
var_dump($link);
