How to use the JSON data response via PHP from Google Insight API

[Lucien Dubois]

Hi,

I try to use the response from the Google Insights API.

I got

$ch = curl_init("https://www.googleapis.com/pagespeedonline/v1/runPagespeed?url=http://code.google.com/speed/page-speed/&key=MyAPIKey");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$res = curl_exec($ch);
$obj = json_decode($res, true);
var_dump($obj); // return NULL ?
echo $obj['pageStats']['numberJsResources']; // doesn't echo anything
print_r($obj['pageStats']['numberJsResources']); 
// doesn't echo anything

But it doesn't return anything. Where am I wrong?

I just copy & pasted your code into my server (replaced the API key), it works for me.

Remove the ['numberJsResources'] from your last statement, here I get:

print_r($obj['pageStats'])

16Array

(

    [numberResources] => 51

    [numberHosts] => 17

    [totalRequestBytes] => 8352

    [numberStaticResources] => 28

    [htmlResponseBytes] => 197612

    [cssResponseBytes] => 129291

    [imageResponseBytes] => 269834

    [javascriptResponseBytes] => 1161486

    [otherResponseBytes] => 166150

    [numberJsResources] => 16

    [numberCssResources] => 5

)

Ok yes! You made me realize it works on web server but not on local server. Thank you.
