I've been trying for hours now to get the title field from the json code. Below is my php code
$search = $_GET['search'];
$new = str_replace(' ', '+', $search);
$url = "http://api.themoviedb.org/3/search/movie?api_key=###&query=".$new;
$json = file_get_contents($url);
$json_data = json_decode($json, true);
$title = $json_data->title;
echo $title;
this is the var dump of the json
array(4) { ["page"]=> int(1) ["results"]=> array(1) { [0]=> array(10) { ["adult"]=> bool(false) ["backdrop_path"]=> string(32) "/4uJZvmEMX6Z6ag3bzym5exLY9wI.jpg" ["id"]=> int(65) ["original_title"]=> string(6) "8 Mile" ["release_date"]=> string(10) "2002-11-08" ["poster_path"]=> string(32) "/dXzTrKwpbLpCqn8O70FUUhNbYQT.jpg" ["popularity"]=> float(3.792332418578) ["title"]=> string(6) "8 Mile" ["vote_average"]=> float(6.2) ["vote_count"]=> int(185) } } ["total_pages"]=> int(1) ["total_results"]=> int(1) }
the error i keep getting is Notice: Trying to get property of non-object
any help would be greatly appreciated.
$json_data = json_decode($json, true);
will return an array not object
so you need to use as
$json_data["title"];
NOTE : Your json decoded array is nested so you may need to use as in your case.
$json_data["results"][0]["title"];
Or better loop through and get the desired data.
I just started using PHP and I THINK this might help you... but i'n not sure
foreach($json_data as $key => $value){
if($key == "results"){
$json_data2 = $value;
}
}
foreach($json_data2 as $key => $value){
if($key == "original_title"){
$title = $value;
}
}
echo $title;

I'm accessing data from an API using json_decode. The code I have returns the array of ALL the date (see below), but I want to return specific data such as 'name' or 'locale'.
$json_string = 'http://api.duedil.com/open/search?q=Surfing%20Sumo&api_key=THE-API-KEY';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
echo '<pre>';
var_dump($obj);
This is what is returned (this is abbreviated to save space here):
array(1) {
["response"]=>
array(2) {
["pagination"]=>
string(79) "http://api.duedil.com/open/search?query=Duedil&total_results=6&limit=5&offset=5"
["data"]=>
array(5) {
[0]=>
array(4) {
["company_number"]=>
string(8) "06999618"
["locale"]=>
string(14) "United Kingdom"
["name"]=>
string(14) "Duedil Limited"
["uri"]=>
string(51) "http://api.duedil.com/open/uk/company/06999618.json"
}
You could just use
$name = $obj['response']['data'][0]['name'];
$locale = $obj['response']['data'][0]['locale'];
if you have multiple return values, you could loop over them
foreach ($obj['response']['data'] as $item) {
$name = $item['name'];
$locale = $item['locale'];
}
try this sample code:
<?php
$data = isset($obj['response']['data'])?$obj['response']['data']:FALSE;
if(is_array($data))
{
foreach ($data as $value) {
echo $value['name'];
echo $value['locale'];
}
}
I am trying to retrieve data from this array in php.
array(2) {
["getWysiwyg"]=>
string(37) "[{"basicsDescription":"<p><br></p>"}]"
["getGoal"]=>
string(27) "[{"iconURL":"","title":""}]"
}
I tried Input::get('getWysiwyg') it returns [{"basicsDescription":"<p><br></p>"}]
Now how could i get the value i.e <p><br></p>
As I see your array items are json encoded ..
Try to decode them as this:
foreach($array as $key=>$value){
$decodedValue = json_decode($value, true);
print_r($decodedValue);
}
You have to use json_decode(), because the string [{"basicsDescription":"<p><br></p>"}]represents an array with an object in JSON.
$string = '[{"basicsDescription":"<p><br></p>"}]';
$objectArray = json_decode( $string );
$objectArray now looks like:
array(1) {
[0]=>
object(stdClass)#1 (1) {
["basicsDescription"]=>
string(11) "<p><br></p>"
}
}
To get the value of basicsDescription you need to access the array in this case with the index 0, then you have the object:
$object = $objectArray[0];
Once you've got the object you can access it's attributes with the object operator ->:
$object->basicsDescription;// content: <p><br></p>
Short form of this:
$string = '[{"basicsDescription":"<p><br></p>"}]';// in your case Input::get('getWysiwyg')
$objectArray = json_decode( $string );
$objectArray[0]->basicsDescription;
If it's possible, that there are more than one item in it, you should go for foreach
If all items of your array representing JSON strings you can use array_map():
$array = array(
"getWysiwyg" => '[{"basicsDescription":"<p><br></p>"}]',
"getGoal" => '[{"iconURL":"","title":""}]'
);
$array = array_map( 'json_decode' , $array );
echo "<pre>";
var_dump( $array );
This will output:
array(2) {
["getWysiwyg"]=>
array(1) {
[0]=>
object(stdClass)#1 (1) {
["basicsDescription"]=>
string(11) "<p><br></p>"
}
}
["getGoal"]=>
array(1) {
[0]=>
object(stdClass)#2 (2) {
["iconURL"]=>
string(0) ""
["title"]=>
string(0) ""
}
}
}
Decode and print as follows
$object = json_decode(Input::get('getWysiwyg'));
print $object[0]->basicsDescription;
or directly with the help of array dereferencing
print json_decode(Input::get('getWysiwyg'))[0]->basicsDescription;
will output
<p><br></p>
This is one of those that should be easy. I'm not even sure if "subset" is the right way to describe it.
My initial array looks like this:
array(3) { [0]=> array(5) { ["id"]=> string(1) "1" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "50" ["date"]=> string(19) "2013-05-15 01:58:48" ["created"]=> string(19) "2013-05-15 01:58:48" } [1]=> array(5) { ["id"]=> string(2) "11" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "45" ["date"]=> string(19) "2013-05-15 03:34:59" ["created"]=> string(19) "2013-05-15 03:37:01" } [2]=> array(5) { ["id"]=> string(2) "25" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "50" ["date"]=> string(19) "2013-05-15 22:47:46" ["created"]=> string(19) "2013-05-15 22:52:02" } }
I'd ultimately like to end up with just the date and price values, swap them so that date is first in the array, reformat the date, and convert it to a json array that looks something like this:
[{"date":"Mar. 15","price":"50"},{"date":"Mar. 15","price":"45"},{"date":"Mar. 15","price":"50"}]
I ran a foreach statement to get at the data and reformat the date, then went out of my league with splice, unset, and other functions that took me in the wrong direction. Any ideas?
Try this
$array = array();
for($i = 0 ; $i<count($your_array);$i++) {
$a=array();
$a['date'] = $your_array[$i]['date'];
$a['price'] = date("F .j",strtotime($your_array[$i]["date"]));
array_push($array,$a);
}
json_encode($array);
Output
[{"date":"Mar. 15","price":"50"},{"date":"Mar. 15","price":"45"},{"date":"Mar. 15","price":"50"}]
Codepad
This should get you there
$ret = array();
foreach ($source as $rec){
$ret[] = array("date"=>$rec["date"], "price"=>$rec["price"]);
}
$json = json_encode($ret);
Create a quick function to create another array with only selected elements:
function datePriceToJson($array) {
$a = array();
foreach($array as $i => $a) {
$a[] = array("date" => $a['date'], "price" => $a['price']); //Creae a new array based on the one you want
}
return json_encode($a);
}
datePriceToJson($array);
You need to reconstruct array using correct foreach and the use json_encode to get the json
$req_array = array();
foreach($youArray as $value)
{
$temp = array();
$temp['date'] = $value['date'];
$temp['price'] = $value['price'];
$req_array[] = $temp;
}
$json = json_encode($req_array);
echo $json;
see demo
Hope it helps you
$infos =array(
array("id" =>"1","price"=>"50","date"=>"2013-05-15 01:58:48"),
array("id" =>"2","price"=>"55","date"=>"2013-06-15 01:58:48")
);
$i=0;
foreach ($infos as $info )
{
$infos[$i]["date"]= date("F .j",strtotime($info["date"]));
$i++;
}
echo json_encode($infos);
I'm receiving a JSON and trying to interpret some values using PHP.
Example snippet from a JSON dump:
["11811"]=>
object(stdClass)#15 (11) {
["parent_area"]=>
NULL
["generation_high"]=>
int(19)
["all_names"]=>
object(stdClass)#16 (0) {
}
["id"]=>
int(11811)
["codes"]=>
object(stdClass)#17 (3) {
["ons"]=>
string(2) "08"
["gss"]=>
string(9) "E15000008"
["unit_id"]=>
string(5) "41421"
}
["name"]=>
string(10) "South East"
["country"]=>
string(1) "E"
["type_name"]=>
string(15) "European region"
["generation_low"]=>
int(1)
["country_name"]=>
string(7) "England"
["type"]=>
string(3) "EUR"
}
As there is lots of (nested) data, I need to obtain the value of ["name"] where ["type_name"] == 'European region'.
Thanks.
You could use array_filter()
$data_array = array(...);
function is_european($data) {
return $data->type_name == 'European region';
}
$filtered = array_filter($data_array,'is_european');
And then use filtered array to obtain values.
Maybe a better way would be to use JsonPath, like this, assuming your array is a result of decoding JSON (object):
$names = jsonPath($data_object, "$.[?(#['type_name'] == 'European region')].name");
Haven't tried this myself, it may need a bit of correction.
Try this:
<?php
$json = JSON_decode(str,true);
$arr = Array();
foreach($json as $f) {
/* eg. $f = $json["11811"] */
if($f['type_name'] == 'European region') {
$arr[] = $f['name'];
}
}
?>
I'm trying to get this array ($resdata) with object(SimpleXMLElement) into a php array:
$resdata =
array(59) {
[0]=> ...
[10]=> object(SimpleXMLElement)#294 (28) {
["reservation_id"]=> string(7) "8210614"
["event_id"]=> string(6) "279215"
["space_reservation"]=> array(2) {
[0]=> object(SimpleXMLElement)#344 (9) {
["space_id"]=> string(4) "3760"
["space_name"]=> string(9) "205"
["formal_name"]=> string(33) "Center" }
[1]=> object(SimpleXMLElement)#350 (9) {
["space_id"]=> string(4) "3769"
["space_name"]=> string(9) "207"
["formal_name"]=> string(32) "Right" } } }
}
I've tried:
$res = (array)$resdata;
$reservation = $res['reservation'];
$result = array();
foreach ($reservation as $key => $value){
$res = array($value);
$spid = $res[0]->space_reservation->space_id;
echo $value->event_id."<br />";
echo $spid."<br />";
}
This only outputs the first space_id and I need to get all the space_ids within "space_reservation" array. Not all records will have multiple space_ids. Any help pointing me in the right direction is appreciated. Not sure if I should use xpath but I need to re-write my foreach statement regardless.
I was hoping to be able to literally convert all references to "object(SimpleXMLElement)#_ (#)" to "array(#)"
[10]=> array (28) {
["reservation_id"]=> string(7) "8210614"
["event_id"]=> string(6) "279215"
["space_reservation"]=> array(2) {
[0]=> array (9) {
["space_id"]=> string(4) "3760"
["space_name"]=> string(9) "205"
["formal_name"]=> string(33) "Center" }
[1]=> array (9) {
["space_id"]=> string(4) "3769"
["space_name"]=> string(9) "207"
["formal_name"]=> string(32) "Right" } } }
}
the function in my cakephp 1.3 controller is this:
$xml = simplexml_load_string($string);
$this->data['events']= $xml->children();
$resdata = $this->data['events'];
$this->set('resdata',$resdata);
I think this should do what you are looking for:
foreach ($resdata as $res) {
echo $res->event_id . '<br />';
foreach ($res->space_reservation as $reservation) {
echo $reservation->space_id . '<br />';
}
}
Googled it and found a general solution for any SimpleXMLElement to array conversion:
function xml2array($xml) {
$arr = array();
foreach ($xml as $element) {
$tag = $element->getName();
$e = get_object_vars($element);
if (!empty($e)) {
$arr[$tag] = $element instanceof SimpleXMLElement ? xml2array($element) : $e;
}
else {
$arr[$tag] = trim($element);
}
}
return $arr;
}
