我怎么找到这个div？ （PHP Simple HTML DOM Parser）

Question

This is my code:

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

It outputs all result of the Google Search Page under the Search "BA236".

The problem is I dont need all of them and the Information I need is inside a div that has no id or class or anything else.

The div I need is inside the first

<div class="g">

on the Page, so maybe I should try something like this:

<?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;
?>

But the Problem of that is, if I load the page it shows me nothing except this:

Notice: Trying to get property of non-object in C:\xampp\htdocs...\simpletest2.php on line 4

So how can i get the div i´m searching for and what am I doing wrong ?

Edit:

Solution:

<?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;
?>

Or:

<?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;
?>

Answer 1

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;
?>

result:

British Airways Flight 236

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;

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;
?>

not ('div[class=g], 0')

but ('div[class=g]')[0]
