Question

The json data object below is what’s returned from a custom Google search API request. I need to extract each of the “url” elements and place them into an array (using PHP).

myArray = {url1, url2, url3, etc…}

How?

data =  '{
"responseData": 
{
    "results":
    [
        {
            //etc
        }
    ]
}

Answer 1

Am I right that you have JSON string? Use json_decode to decode it. After that you can use

 array_map(function($x){
     return $x->url;
 },$var->responceData->results);

(Requires PHP 5.3 for anonymous function, you can use no anonymous ones if use PHP5.2 or older)

For later versions:

function smth($x){
    return $x->url;
}
array_map('smth',$var->responceData->results);
