尝试使用PHP中的简单html dom解析器从span获取内容

Question

我正在尝试从此范围获取内容

<span class="contact-seller-name ng-binding">martin</span>

这是我的代码

require 'simple_html_dom.php';

$url = "https://www.donedeal.ie/cars-for-sale/bmw-520d-m-sport-f10/14712042?campaign=3";

$html = file_get_html($url);

$value = $html->find("span[class*=contact-seller-name ng-binding]", 0);

echo $value->innertext;

但问题是我总是遇到这个错误：

尝试将$value用作数组：

<?php 
    // finding against the mutltiple
    // 0 is for the first span element
    $value = $html->find('span#ur_span_id');
    foreach($a_span as $p) {
        $span_test =  $p->outertext; 
    }
    //can use class too in find section
?>
