php curl returning empty array

Question

I am trying to get some webpage content using php curl.

I have this php code:

$target_url="http://me.dealintech.com/partho.php";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $target_url);
curl_setopt($ch, CURLOPT_HEADER, 0);
$file_contents=curl_exec($ch);
include('simple_html_dom.php');
$html = str_get_html($file_contents); 
$elem = $html->find('div[id=basic_info_content]');
echo "var_dump output: ";
var_dump($elem);

And the output I get is :

[ here I get the whole webpage contents I targeted ]

var_dump output: array(0) { }

So I am getting all contents but not the specific div content. How I can get that using div id or/and class

Just adding to @AmitRajput comment, echo $html; please. Does that div you are looking at show? — Matt

Yes. output of echo $html; is very large string. Rather you see dealintech.com/a.php which shows the output you are asking for. — partho

You need to use the CURLOPT_RETURNTRANSFER option to make curl_exec return the contents of the URL rather than output it.

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

If you're not using any other cURL options, you could instead use the simpler file_get_contents:

$file_contents = file_get_contents($target_url);

And Simple HTML DOM Parser includes a function that does this automatically for you:

$html = file_get_html($target_url);

that almost answered my question. But I am looking for specific div content. Can you say,how?

In my target page there's a div id=basic_info_content. I want to get text of that div. (Which I said in my question). Please give an idea

That part of your code should work fine. The only problem was the way you were getting the HTML.

You can also write it as $elem = $html->find("#basic_info_content").

output of $elem = $html->find("#basic_info_content"); print_r($elem); is very large. You can see here the output dealintech.com/a.php
