In the for loop I am trying to count the amount of flights in a nested array decoded from a JSON feed. Unfortunately it only shows 2 flights, when more flights are available. What am I doing wrong?
Json feed example from endpoint
{
"response": [
{
"flight": {
"number": "6204",
"iata_number": "HV6204",
"icao_number": "TRA6204"
}
},
{
"flight": {
"number": "7012",
"iata_number": "TB7012",
"icao_number": "JAF7012"
}
},
{
"flight": {
"number": "6652",
"iata_number": "HV6652",
"icao_number": "TRA6652"
}
},
{
"flight": {
"number": "1925",
"iata_number": "W61925",
"icao_number": "WZZ1925"
}
},
{
"flight": {
"number": "5075",
"iata_number": "W65075",
"icao_number": "WZZ5075"
}
},
{
"flight": {
"number": "4289",
"iata_number": "W64289",
"icao_number": "WZZ4289"
}
},
{
"flight": {
"number": "7861",
"iata_number": "W67861",
"icao_number": "WZZ7861"
}
},
{
"flight": {
"number": "3066",
"iata_number": "FR3066",
"icao_number": "RYR3066"
}
}
]
} .
The PHP code example
<?php
$url = 'https://api.endpoint'; // path to JSON file
$data = file_get_contents($url);
$flights = json_decode($data, true);
for($i=0; $i<=count($flights['response'][0]['flight']['iata_number']); $i++) {
echo "Flightnumber" . $flights['response'][$i]['flight']["iata_number"] . '<br/>';
}
?>
Any help is very appreciated
What really should be used here is foreach. With foreach you don't have to care about count() of your array:
$url = 'https://api.endpoint'; // path to JSON file
$data = file_get_contents($url);
$flights = json_decode($data, true);
foreach ($flights['response'] as $item) {
echo $item['flight']['iata_number'] . '<br />';
}
Simple demo is here.
If you still want to use for-loop, it should look like:
for ($i = 0; $i < count($flights['response']); $i++) {
echo $flights['response'][$i]['flight']['iata_number'] . '<br />';
}
for($i=0; $i<count($flights['response'][0]['flight']['iata_number']); $i++) {
echo "Flightnumber" . $flights['response'][$i]['flight']["iata_number"] . '<br/>';
}
count($flights['response'][0]['flight']['iata_number']) is always going to equal one, so you're only looping twice as would be expected (two flights). My guess is that's supposed to be count($flights['response']) or something similar.
You can use array_walk_recursive
array_walk_recursive($jarr, function($v, $k) use (&$flights){
if($k == 'iata_number') $flights[] = $v;
});

i have the following Array Structure from Facebook Graph API response.
"data": [
{
"actions": [
{
"action_type": "comment",
"value": "2"
},
{
"action_type": "offsite_conversion",
"value": "1606"
}
],
"date_start": "2017-04-03",
"date_stop": "2017-05-02"
},
{
"actions": [
{
"action_type": "post",
"value": "2"
},
{
"action_type": "post_reaction",
"value": "33"
},
{
"action_type": "page_engagement",
"value": "816"
},
{
"action_type": "post_engagement",
"value": "807"
},
{
"action_type": "offsite_conversion",
"value": "1523"
}
],
"date_start": "2017-04-03",
"date_stop": "2017-05-02"
},
]
The Number of values is flexible and i want to get the value from "offsite_conversion". Normally i would do it for example like that:
data['data'][0]['actions']['1']['value']
But in that case this doesn't work because ['1'] is variable.
Use a loop and test the action type.
foreach ($data['data'][0]['actions'] as $action) {
if ($action['action_type'] == 'offsite_conversion') {
$result = $data['value'];
break;
}
}
because "offsite_conversions" is always the last
If $data['data'][0]['actions'][LAST VALUE]['value'] is what you're looking for:
Your idea of counting should work then:
$actions = $data['data'][0]['actions'];
$index = count($actions) - 1;
$value = $actions[$index]['value'];
So not completely clear what are you trying to achieve, but in a simple way you can just iterate over your $data array:
$needed_values = array();
foreach ($data['data'] as $item) {
foreach ($item['actions'] as $action) {
if ($action['action_type'] == 'offsite_conversion') {
$needed_values[] = $action['value'];
}
}
}
Barmar has the best approach if you don't know where it is, but it's much easier if you want the last one:
$result = end($data['data'][0]['actions'])['value'];
Pretend $json holds the data from facebook
<?php
$data = json_decode($json);
$conversions = 0;
foreach ($data as $datum) {
foreach ($datum['actions'] as $action) {
if ($action['action_type'] === 'offsite_convserion') {
$conversions += (int)$action['value'];
break;
}
}
}
I have an array which has a key with multiple content. I want to get that array which includes the key that I search .
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$results = array_filter($arr['people'], function($people) {
return $people['id'] == 8080;
});
echo json_encode($results);
This will return:
{"id":"8080","content":"foo","member":[123,456],"interval":7}
I want that:
$results = array_filter($arr['people'], function($people) {
return $people['member'] == 123;
});
And this does not work.
Have somebody an idea?
As #JonStirling said in comment. Use in_array() function.
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$searchId = 123;
$results = array_filter($arr['people'], function($people) use ($searchId) {
return in_array($searchId, $people['member']);
});
echo json_encode($results);
Result:
[{"id":"8080","content":"foo","member":[123,456],"interval":7}]
See if this helps:
$arr = json_decode('{"people":[
{
"id": "8080",
"content": "foo",
"member": [123, 456],
"interval": 7
},
{
"id": "8097",
"content": "bar",
"member": [1234, 4567],
"interval": 7
}
]}', true);
$results = array_filter($arr['people'], function($people) {
for($i=0; $i<count($people['member']); $i++){
return $people['member'][$i] == 123;
}
});
echo json_encode($results);
The out come will be:
[{"id":"8080","content":"foo","member":[123,456],"interval":7}]
If you want to do it withouth 'array_filter' you can try this:
function search($arr, $id, $arrayValue)
{
$people = null;
foreach ($arr['people'] as $a)
{
if ($a['id'] == $id)
{
$people = $a;
}
}
$arrayWeAreLookingFor = null;
foreach ($people as $property => $value)
{
if (is_array($value))
{
foreach ($value as $v)
{
if ($v == $arrayValue)
{
$arrayWeAreLookingFor = $people[$property];
}
}
}
}
return $arrayWeAreLookingFor;
}
var_dump(search($arr, 8080, 123));

Get data from JSON file with PHP [duplicate]
(3 answers)
Closed 6 years ago.
I want print specific vars from array inside a document.
JSON structure:
{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
},
etc
]
}
}
I am trying to do this in PHP (and already decoded that json). How can I access and print all ids using foreach or for?
I can not understand how I can manage "return" scope.
You can decode the json contents and use it like an array. This should work:
$json = json_decode($string, true);
$contacts = $json['return']['contacts'];
foreach($contacts as $contact){
echo $contact['contact']['id'];
}
Json decode to array:
$json = json_decode($strjson, true); // decode the JSON into an associative array
and
echo "<pre>";
print_r($json);
And foreach:
foreach ($json as $key => $value) {
echo $key . " ". $value. "<br>";
}
Working example:
$json = '{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
}
]
}
}';
$json = json_decode($json, true);
print_r($json);
foreach ($json['return']['contacts'] as $val) {
echo $val['contact']['id']."<br>";
}
Try this code:
$json ='
{
"return": {
"string": "2222",
"contacts": [
{
"contact": {
"id": "09890423890"
}
},
{
"contact": {
"id": "2423444"
}
},
{
"contact": {
"id": "24242423"
}
},
etc
]
}
}
';
$array = json_decode($json,TRUE);
foreach($array['return']['contacts'] as $value ){
echo $value['id'];
}
Use file_get_contents function if you want to pull data from file.
{
"responseData": {
"results": [
{
"title": "sobig",
"titleNoFormatting": "test",
},
{
"title": "test 2 ",
"titleNoFormatting": "test 2sd",
},
{
"title": "asdasdasda",
"titleNoFormatting": "asdasdasd",
},
{
"title": "A Warming",
"titleNoFormatting": "A Warming",
}
.
.
.
.
{
"title": "last thing",
"titleNoFormatting": "sada",
}
],
I have json files like this.
for($i=$veri1; $i <= $veri2; $i++) {
$uri = "http://test.com/json/".$i."/0";
$json = json_decode(file_get_contents($uri));
if($json->data->price >= $nakit && $json->data->odds >= $oran)
{
I'm getting some data with this code correctly from another json file.
i want get data from first json code, if "title" == "sobig" . How can I do that.
$json->responseData->results->title == sobig is not working. How can I get data if title is sobig
$json= json_decode($response, true);
foreach ($json['responseData']['results'] as $key => $value) {
if ($value == 'sobig') {
// found it
}
}
Try this example to see if this may fix your issue.
<?php
$json = '{ "responseData": {
"result" : [
{ "title": "sobig" , "titleNo":"test"},
{ "title": "loco" , "titleNo":"test"},
{ "title": "tom" , "titleNo":"test"}
]
}}';
$jsonDecoded = json_decode($json);
foreach ($jsonDecoded->responseData->result as $key => $value) {
var_dump($value); echo '<br>';
if($value->title == 'sobig'){
echo "we did it!!";
echo "<br>";
}
}
?>
I place a couple of var dumps so you can see the stucture of your object and why you need to use the foreach
I'm trying to search for duplicate classids in a json array and for each duplicate found, echo the dulicate id... This is just an example of the json file.
I've tried a few things but failed - if I posted my code it wouldn't work with this sample code. It's a lot more complex as after I am check another json file for matching ids... and a bunch of other stuff.
Thanks in advance.
{
"response": {
"received": [
{
"items": [
{
"classid": "356464564",
},
{
"classid": "456456456",
},
{
"classid": "356464564",
},
{
"classid": "721248158",
}
]
,
"time_created": 1440782791,
},
{
"items": [
{
"classid": "845362344",
},
{
"classid": "2543634754",
},
{
"classid": "2543634754",
},
{
"classid": "5967856788",
}
]
,
"time_created": 1440456791,
}
}
}
This can do what you're looking for:
<?php
$array = json_decode('{
"response": {
"received": [
{
"items": [
{
"classid": "356464564"
},
{
"classid": "456456456"
},
{
"classid": "356464564"
},
{
"classid": "721248158"
}
]
,
"time_created": 1440782791
}
]
}
}', true);
$cleanArray = array();
foreach($array['response']['received'][0]['items'] as $classid)
{
if(in_array($classid['classid'], $cleanArray))
echo "Duplicate found: ".$classid['classid'].'<br>';
else
$cleanArray[] = $classid['classid'];
}
?>
Try this, it makes the array smaller as matches are found, thus making the algorithm more efficient.
$arr = json_decode($json , true);
$items_array = array_column($arr['response']['items'], 'classid');
foreach ($items_array as $k => $val) {
foreach ($items_array as $k2 => $val2) {
if ($k2 != $k) {
if ($val == $val2) {
unset($items_array[$k]);
if (isset($final[$val])) {
$final[$val]++;
} else {
$final[$val] = 1;
}
}
}
}
}
var_dump($final); //will show you your duplicates
