retrieving Google search results

问题

i read your post on

simple php script to retrieve google keyword search completion

and i was wondering how would you go 'echo' the next page? here's my script..

$search = 'query';

$x = json_decode( file_get_contents( 'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=' . urlencode( $search ) ) );

echo $x->responseData->results[0]->url;

i was able to 'echo' out the url, i am stucked in going to the next page and 'echo' out the next url's

thanks sir

You change the index:

echo $x->responseData->results[1]->url;

To loop through all:

foreach ($x->responseData->results as $r) {
    echo $r->url, "\n";
}

You can inspect the complete result with var_dump($x);.

To retrieve another page of results, you can use the start parameter, e.g.:

$x = json_decode(
    file_get_contents(
    'http://ajax.googleapis.com/ajax/services/search/web?v=1.0&start=4&q='
    . urlencode( $search )));

You can request 8 results instead of 4 with rsz=large.

For anyone else looking to interface with Google and stumbled on this solution, the code above now returns this response: object(stdClass)#1 (3) { ["responseData"]=> NULL ["responseDetails"]=> string(143) "The Google Web Search API is no longer available. Please migrate to the Google Custom Search API (https://developers.google.com/custom-search/)" ["responseStatus"]=> int(403) }

Please migrate to the Google Custom Search API (https://developers.google.com/custom-search/) I hope this saves someone some time!
