Looping through JSON with PHP to get children -

i've been trying morning appear quite simple , i'm failing miserably.

i have api request returns valid json data , need loop through various values in php several nodes application.

here snippet of json

{ "results": [     {         "date": "2015-06-01",         "rates": [             {                 "id": 1592,                 "name": "weekend promotion",                 "room_rates": [                     {                         "room_type_id": 66,                         "room_type_code": "dlk",                         "sold": 0,                         "sell_limit": null,                         "availability": 25,                         "out_of_order": 0,                         "single": 85,                         "double": 85,                         "extra_adult": null,                         "child": null                     },                     {                         "room_type_id": 90,                         "room_type_code": "dlt",                         "sold": 0,                         "sell_limit": null,                         "availability": 11,                         "out_of_order": 0,                         "single": 85,                         "double": 85,                         "extra_adult": null,                         "child": null                     }, 

and i'm trying do, keep getting following error (edited update curl response):

notice: trying property of non-object in /vagrant/web/web/bookingstep2.php on line 135  warning: invalid argument supplied foreach() in /vagrant/web/web/bookingstep2.php on line 135  notice: trying property of non-object in /vagrant/web/web/bookingstep2.php on line 135  warning: invalid argument supplied foreach() in /vagrant/web/web/bookingstep2.php on line 135 

any ideas i'm doing wrong? line 135 this:

foreach($responsedata $mydata)

$url = 'https://myapi.com/availability?token=xx&from_date='.$from_date.'&to_date='.$to_date;  $options = array(     curlopt_returntransfer => true,   // return web page     curlopt_header         => false,  // don't return headers     curlopt_followlocation => true,   // follow redirects     curlopt_maxredirs      => 10,     // stop after 10 redirects     curlopt_encoding       => "",     // handle compressed     curlopt_useragent      => "test", // name of client     curlopt_autoreferer    => true,   // set referrer on redirect     curlopt_connecttimeout => 120,    // time-out on connect     curlopt_timeout        => 120,    // time-out on response );  $ch = curl_init($url); curl_setopt_array($ch, $options); $result = curl_exec($ch);  curl_close($ch);   // decode response $responsedata = json_decode($result, true);  // put everyting screen var_dump; var_dump($responsedata);  // print_r ( useful arrays ); //print_r($responsedata);  // list review ratings foreach; foreach($responsedata $mydata) {     foreach($mydata->results $values) {         echo $values->rates . "\n";     }  } 

i need able return following nodes....

results>rates>name results>rates>room_rates>room_type_id results>rates>room_rates>availability 

i'm stuck!

the var_dump return array, curl working correctly now.

it looks curl request blame, you're not telling curl you're expecting response, curl passes boolean success initial request, sent successfully.

from php curl_exec page.

returns true on success or false on failure. however, if curlopt_returntransfer option set, return result on success, false on failure.

it's succeeding, you're not telling you're expecting response, returns true.

try this:

$url = 'https://myapi.com/api?token=xxx&from_date='.$from_date.'&to_date='.$to_date;  $options = array(     curlopt_returntransfer => true,   // return web page <-- important 1 tells curl want response.     curlopt_header         => false,  // don't return headers     curlopt_followlocation => true,   // follow redirects     curlopt_maxredirs      => 10,     // stop after 10 redirects     curlopt_autoreferer    => true,   // set referrer on redirect     curlopt_connecttimeout => 120,    // time-out on connect     curlopt_timeout        => 120,    // time-out on response );  $ch = curl_init($url); curl_setopt_array($ch, $options); $result = curl_exec($ch);  curl_close($ch); 

2nd error

now we've got curl working lets address result. remember when json converted each brace ({) produce object, , each square bracket ([) produce array. if follow json can see object back, containing property results. can access using $responsedata->results.

in second foreach you're trying access property of object. results isn't object, it's array (look @ json, contains [, it's array). rates follow through json string , you'll see need this:

foreach($responsedata->results[0]->rates $rate) {     echo $rate->id . "\n"; }
