I just tested out the other option, if you want to work with the current format (php serialized string), use unserialize instead of json_decode.

I only tried out the literal string, which needed some changes near the end to work:
$json_data1='a:1:{i:0;a:18:{s:5:"label";s:27:"/single_event_page.php?id=2";s:9:"nb_visits";i:1;s:7:"nb_hits";i:1;s:14:"sum_time_spent";i:714;s:28:"nb_hits_with_time_generation";s:1:"1";s:19:"min_time_generation";d:0.409999999999999975575093458246556110680103302001953125;s:19:"max_time_generation";d:0.409999999999999975575093458246556110680103302001953125;s:15:"entry_nb_visits";s:1:"1";s:16:"entry_nb_actions";s:1:"2";s:22:"entry_sum_visit_length";s:3:"715";s:18:"entry_bounce_count";s:1:"0";s:26:"sum_daily_nb_uniq_visitors";i:1;s:32:"sum_daily_entry_nb_uniq_visitors";i:1;s:16:"avg_time_on_page";d:714;s:11:"bounce_rate";s:2:"0%";s:9:"exit_rate";s:2:"0%";s:19:"avg_time_generation";d:0.409999999999999975575093458246556110680103302001953125;s:3:"url";s:42:"http://xxxx.xxx/single_event_page.php?id=2";}}'; // note changed s:52 to s:42 and added }

$obj1 = unserialize($json_data1);

echo "<pre>";
var_dump($obj1);

echo "page hits: ".$page_hits['0'];

Open in new window

returns


Catchable fatal error: Object of class stdClass could not be converted to string in /home/local/public_html/page_hits.php on line 80

so how do i get the nb hits please??
That can have a number of reasons, for starters there is no $page_hits variable in your original posted code so can you check that and if it's there now please show your current code?

opps sorry forgot that part
could you also please post the json string because it could be slightly different than the unserialized php string I have now.
As an aside, after unserializing the string you posted before, the following code works:
echo "nb_hits: ".$obj1[0]['nb_hits'];

Ok, I'll have a look. In the mean time, another question...

Your posted code has an extra bit in it:
['stdClass']

Open in new window

Which is not present in the posts where you ask how to get to the info. Is that part of the problem?

quick check to loop over all items:
foreach ($page_hits[0] as $key => $val) {
    echo "$key: $val<br>";
