New Google Custom Search Api Results - PHP - php

Question

So the new Google custom Search has rolled out and im having trouble displaying the results...
I am using php to return the results in json and am getting a invalid argument in for each error... Here is what i am using...
$url = "https://www.googleapis.com/customsearch/v1?key=MYKEY&cx=017576662512468239146:omuauf_lfve&q=test&callback=json";
$results = file_get_contents($url);
foreach ($results->items as $r)
{
}
Here's the callback when I go to the URL in the browser:
json({
"kind": "customsearch#search",
"url": {
"type": "application/json",
"template": "https://www.googleapis.com/customsearch/v1?q\u003d{searchTerms}&num\u003d{count?}&start\u003d{startIndex?}&hr\u003d{language?}&safe\u003d{safe?}&cx\u003d{cx?}&cref\u003d{cref?}&sort\u003d{sort?}&alt\u003djson"

Answer 1

You should try this:
$results = json_decode(file_get_contents($url));
To be able to correctly decode the response of the service, you may do the following:
$json = file_get_contents($url);
$start = 'json(';
$end = ');';
$substr_start_pos = strpos($json, $start) + strlen($start);
$substr_length = strlen($json) - $substr_start_pos - (strlen($json) - strrpos($json, $end));
$json = substr($json, $substr_start_pos, $substr_length);
$results = json_decode($json);
This may be a bit confusing, but I did this for the following reasons:
The sample response you provided, has a 'json(' string before the actual JSON, and a ');' after it, which can't be decoded with PHP's json_decode.
Simple replacing won't be good, because the actual JSON might contain these substrings as well.

Answer 2

THIS IS TRUE SIMPLE PHP DECODE WILL NOT HELP YOU,
TRY THIS
$data = html_entity_decode($url);
I am sure this will work properly
to try later var dump the date to check the results.
