我对您的代码进行了更改对于这个类：

I made a change to your code where I am searching for the class:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $e = $html->find("div[class=g]");
echo $e[0]->innertext;
?>

结果：

result:

British Airways Flight 236

我用g类寻找div元素，然后打印出第一个元素'0'的计数

I looked for the div elements with class g then I printed the count of the first element '0'

$e = $html-> find ("div [class = g]");
echo $e [0]->innertext;

您的代码：

Your code:

<?php
    include('simple_html_dom.php');
    $html = file_get_html('http://www.google.com/search?q=BA236',false);
    $title=$html->find('div[class=g]')[0]->innertext;
    echo $title;
?>

不是（'div [class = g]，0'） code>

但（'div [class = g]'）[0]
