Videos on google first page

Enumerate all "vidthumb" on the source, then count unique (since source code may contain two instances of vidthumb1, and two instances of vidthumb4. Still totals 2 videos)
I have no idea why they jump in numbers.

Hi,

I have try

substr_count( $str, 'vidthumb' );

Select allOpen in new window

But it not work.

If possible, post full source code you're working on right now.

$google_url = "https://www.google.com/search?q=jquery+tutorial";

$ch = curl_init();
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_URL, $google_url );
$result = curl_exec($ch);
curl_close($ch);

$google_vid = 0;
//$google_vid = substr_count( $result, 'https://www.youtube.com/watch' );
$google_vid = substr_count( $result, 'vidthumb');

echo $google_vid;

Select allOpen in new window

Output is: 0

I have tried with "web design tutorial" keyword with same code that you given and applied it to here: http://slmp-550-4.slc.westdc.net/~web/google-api/

It give me 1 video as a result instead of 2, please check and suggest.

The result is 1, it's correct. If you see two, it means you're checking with your browser which contains cookies and therefore has different results.
You have to use my original code INCLUDING the test echo's to double check.

Yes, You are right, it works now.

Thanks a Lot ...

Hi,

I have got new issue with this method it gives me error from google:

Our systems have detected unusual traffic from your computer network.  This page checks to see if it's really you sending the requests, and not a robot.

please suggest

Thanks

Even if I do hundreds of Google searches in my browser, it won't trip up the system. It probably means you really are doing thousands if not millions of these requests (I saw one search does multiple searches already based on auto complete suggestions?)?
Check this page for more on it:

If you are really doing automated searches, instead of human initiated ones (and therefore, much lower volume), you really have a problem. Maybe add some detection mechanism, and maybe you'll be able to temporarily continue searching by opening a Google search on a browser (on the same computer or other computer inside the network), and filling in the CAPTCHA.
If you don't change ANYTHING at all (same volume of searches), this cycle will continue at the same rate, there's no real way to stop it from happening.
If it's really important you get the results, maybe take a look here: https://www.google.com/work/search/products/gss.html#pricing_content
