I only want to display the text from the condition part, see the JSON below
"forecast": {
"forecastday": [
{
"date": "2017-12-01",
"date_epoch": 1512086400,
"day": {
"maxtemp_c": 4.9,
"maxtemp_f": 40.8,
"mintemp_c": 0.9,
"mintemp_f": 33.6,
"avgtemp_c": 1.8,
"avgtemp_f": 35.2,
"maxwind_mph": 9.8,
"maxwind_kph": 15.8,
"totalprecip_mm": 0,
"totalprecip_in": 0,
"avgvis_km": 18,
"avgvis_miles": 11,
"avghumidity": 88,
"condition": {
"text": "Partly cloudy",
"icon": "//cdn.apixu.com/weather/64x64/day/116.png",
"code": 1003
},
"uv": 0.5
},
My code shows all the parts from condition, i only want the text part.
See my code below:
$json = json_decode($json, true);
foreach ($json['forecast']['forecastday'] as $forecast) {
echo 'date: '.$forecast['date'].'<br />';
foreach ($forecast['day']['condition'] as $condition) {
echo ''.$condition.'<br />';
}
}
$json = json_decode($json, true);
$counter=0;
foreach ($json['forecast']['forecastday'] as $forecast) {
{ if ($counter++ == 0) continue; }
echo 'date: '.$forecast['date'].'<br />';
echo 'date: '.$forecast['day']['condition']['text'].'<br />';
}
So a bit more explanation about how a multidimensional array works.
Each nested array should be treated-accessed/parsed as a new array. So in your example you have the main array $json , this is where magic starts.
After that in order to reach the text you need to map your array to find the route that will get you there. If you go for
print_r($json)
you will see that you get your whole array. Now you can see that you have to access forecast array first and so you do it like $json['forecast'] and you are inside the nested array. Same logic leads you to day field.
New Edit: This will output your second record only.

I have looked around on Google for quite some time now, and I'm unable to find a solution that works for me.
I have this JSON Array:
[
{
"id": 1000,
"userIdent": "ABC1000",
"username": "john.doe",
"contacts": [
{
"id": 2000,
"clientId": 1000,
"email": "john.doe#example.com",
"phone": "",
"name": "",
"isBilling": false,
"isContact": false,
"types": [
{
"id": 3000,
"name": "Home contact"
}
]
}
]
}
]
and I have this PHP code:
$json = json_decode($response, true);
foreach($json as $item) {
echo $item['id'] . "<br>";
echo $item['userIdent'] . "<br>";
echo $item['contacts']['phone'] . "<br><br>";
foreach($json->contacts as $contacts) {
echo $contacts->phone;
echo $contacts['contacts']['phone'];
}
}
I have tried:
$item['contacts']['phone'];
$contacts->phone;
$contacts['contacts']['phone'];
I can't seem to be able to full any of the data from the sub-array "contacts". Any help would be greatly appreciated!
Note:- When you use true while using json_decode() it converts all json data to array(inner or outer). So you need to treat contacts as an array not an object.
So You need to iterate over $item['contacts'] array in the second foreach()
Do like below:-
$json = json_decode($response, true);
foreach($json as $item) {
echo $item['id'] . "<br>";
echo $item['userIdent'] . "<br>";
foreach($item['contacts'] as $contacts) {//treat contacts as an array not as an object
echo $contacts['phone'];
}
}
Output:- https://eval.in/952121 (i have taken phone number for testing purpose)
You have made a mistake, on your json, the contacts property is an array, so you can't access it (either in javascript or php) as an object with $contacts->contacts['phone'].
You should do something like that : $contacts->contacts[0]['phone'] or iterate other each contacts if there may be many.
Your code should look more like this
foreach($json as $item) { // 1
echo $item['id'] . "<br>";
echo $item['userIdent'] . "<br>";
foreach($item['contacts'] as $contact) { // 2
echo $contact['phone'];
}
}
So in the first foreach you start iterating over you entire array of items (1). Inside an item is an array contacts, so you start iterating over that with a new foreach (2). Each contact can be accessed directly inside the inner foreach.
Also, on decoding you said you wanted an array as output, so you should expect that and always access it like an array (square braces). If you would have gone for an object, the $contacts->phone syntax would work, but you shouldn't mix them like you are doing.
I hope this makes sense. Feel free to ask if not.
what am i doing wrong here?
when i have only One result coming back this code works perfectly
$someObject = json_decode($data);
$id=$someObject->clips[0]->id;
but when i want to do a loop because i may get back 10 results this code is not working, i am sure i am missing something very simple here
$someObject = json_decode($data);
//var_dump($someObject);
foreach($someObject as $json){
echo $json->clips[0]->id;
}
EDIT:
this solution worked for anyone else who comes looking
foreach ($someObject->clips as $clip){
echo $clip->id. "<br>";
}
not sure how the other one answers the for loop issue i was having however.
You need to change this index [0] to dynamic index.
foreach($someObject as $k => $json){
echo $json->clips[$k]->id; // Insert $k here
}
change this
foreach($someObject as $json){
echo $json->clips[0]->id;
}
to
$i=0;
foreach($someObject as $json){
echo $json->clips[$i]->id;
$i++;
}
or as miken32 stated in the comment
foreach ($someObject->clips as $clip){
echo $clip->id;
}
read this reference: control-structures.foreach.php
in php array if you want to get all of items iterate you can use foreach
imaging you have this sample json:
{
"clips": [{
"id": 1,
"name": "test",
"tags": [
"tag1",
"tag2",
"tag3"
]
},
{
"id": 2,
"name": "test2",
"tags": [
"tag4",
"tag5",
"tag6"
]
}
]
}
if you want to get clips and tag list you can use this code:
<?php
$jsonText = '{"clips": [{"id": 1,"name": "test","tags": ["tag1","tag2","tag3"]},{"id": 2,"name": "test2","tags": ["tag4","tag5","tag6"]}]}';
$jsonObj = json_decode($jsonText);
// in this loop you can get clipObject
foreach($jsonObj->clips as $clipObj){
echo "clip id:" . $clipObj->id . "<br>\n";
echo "clip name:" . $clipObj->name. "<br>\n";
// in this loop you can get tags
foreach($clipObj->tags as $tag){
echo "clip tag:" . $tag. "<br>\n";
}
}
I need PHP JSON help.
I have current output :
{
"status": 200,
"response_msec": 15,
"data": {
"android": {
"test1": 15,
"test2": 6,
"test3": 15,
"test4": 101,
"test5": 87,
"test6": 8,
"test9": 119,
"test10": 101,
"test11": 107
}
}
}
I need print this value : test1 , test2 , test3 ...,test11 .
I have tested some method :
$json = json_decode($result, true);
$dec = (Array)json_decode($result);
print_r ($dec["android"]);
and
foreach ($array as $value)
{
echo $value->android;
}
But not work.
You are missing the ['data'] key,
<?php
$json = '{"status":200,"response_msec":15,"data":{"android":{"test1":15,"test2":6,"test3":15,"test4":101,"test5":87,"test6":8,"test9":119,"test10":101,"test11":107}}}';
$array = json_decode($json, true);
var_dump(array_keys($array['data']['android']));
Check here i have made a php sandbox http://sandbox.onlinephpfunctions.com/code/6f97a9bb499b54919b40d4d12f49049fdd732aef
Also, You can use the function array_keys() to get only the keys of an array, that's what i did.
Your code should work if the json string is assigned to $value. It's just you forgot to include to get the data "data" from "value". Your 3rd line of the first method should look like this:
print_r ($dec["data"]["android"]);
Have a great day
I'm retrieving bibliographic data via an API (zotero.org), and it is similar to the sample at the bottom (just way more convoluted - sample is typed).
I want to retrieve one or more records and display certain values on the page. For example, I would like to loop through each top level record and print the data in a nicely formated citation. Ignoring the proper bib styles for the moment, let's say I want to just print out the following for each record returned:
author1 name, author2 name, article title, publication title, key
This doesn't match the code, because I've clearly been referencing the key value pairs incorrectly and will just make a mess of it.
The following is laid out like the data if I request JSON format, though I can request XML data instead. I'm not picky; I've tried using each with no luck.
[
{
"key": "123456",
"state": 100,
"data": {
"articleTitle": "Wombat coprogenetics: enumerating a common wombat population by microsatellite analysis of faecal DNA",
"authors": [
{
"firstName": "Sam C.",
"lastName": "Smith"
},
{
"firstName": "Maxine P.",
"lastName": "Jones"
}
],
"pubTitle": "Australian Journal of Zoology",
"tags": [
{
"tag": "scary"
},
{
"tag": "secret rulers of the world"
}
]
}
},
{
"key": "001122",
"state": 100,
"data": {
"articleTitle": "WOMBAT and WOMBAT-PK: Bioactivity Databases for Lead and Drug Discovery",
"authors": [
{
"firstName": "Marius",
"lastName": "Damstra"
}
],
"pubTitle": "Chemical Biology: From Small Molecules to Systems Biology",
"tags": [
{
"tag": "Wrong Wombat"
}
]
}
}
]
If there is a mistake in brackets, commas, etc. it is just a typo in my example and not the cause of my issue.
decode your json as array and iterate it as any array as flowing:
$json_decoded= json_decode($json,true);
$tab="\t";
foreach ($json_decoded as $key => $val) {
echo "Article ".$val["key"]."\n" ;
echo $tab."Authors :\n";
foreach ($val["data"]["authors"] as $key => $author){
echo $tab.$tab. ($key+1) ." - ".$author["firstName"]. " ".$author["lastName"]."\n";
}
echo $tab."Article Title: ".$val["data"]["articleTitle"] ."\n";
echo $tab."Publication Title: ".$val["data"]["pubTitle"] ."\n";
echo $tab."Key: ".$val["key"]."\n";
}
run on codepad
and you can use the same method for xml as flowing:
$xml = simplexml_load_string($xmlstring);
$json = json_encode($xml);
$json_decoded = json_decode($json,TRUE);
//the rest is same
for xml you can use the SimpleXml's functions
or DOMDocument class
Tip
to know the structure of your data that api return to you after it converted to array use var_dump($your_decoded_json) in debuging
Something like this might be a good start for you:
$output = [];
// Loop through each entry
foreach ($data as $row) {
// Get the "data" block
$entry = $row['data'];
// Start your temporary array
$each = [
'article title' => $entry['articleTitle'],
'publication title' => $entry['pubTitle'],
'key' => $row['key']
];
// Get each author's name
foreach ($entry['authors'] as $i => $author) {
$each['author' . ++$i . ' name'] = $author['firstName'] . ' ' . $author['lastName'];
}
// Append it to your output array
$output[] = $each;
}
print_r($output);
Example: https://eval.in/369313
Have you tried to use array_map ?
That would be something like:
$entries = json_decode($json, true);
print_r(array_map(function ($entry) {
return implode(', ', array_map(function ($author) {
return $author['firstName'];
}, $entry['data']['authors'])) . ', ' . $entry['data']['articleTitle'] . ', ' . $entry['key'];
}, $entries));
I'm having a bit of trouble here...
I'm trying to grab some values from a json file here, and it can be formatted here.
The json file looks like this:
{
"type": "success",
"message": "OK",
"data": {
"mainWeaponStats": [
{
"category": "Machine guns",
"timeEquipped": 3507,
"startedWith": null,
"code": "mgRPK",
"headshots": 18,
"name": "RPK",
"kills": 100,
"deaths": null,
},
{
"category": "Handheld weapons",
"timeEquipped": 5452,
"startedWith": null,
"code": "wahUGL",
"headshots": 1,
"name": "Underslung Launcher",
"kills": 108,
"deaths": null,
},
{
"category": "Sniper rifles",
"timeEquipped": 307,
"startedWith": null,
"code": "srMK11",
"headshots": 0,
"name": "MK11",
"kills": 2,
"deaths": null,
},
And so on.
I want to grab the kills of one of these items. Meaning I want to give a parameter like "Underslung Launcher" and return with 108.
In this case, the "Underslung Launcher".
I'm looking for a code like this:
$gamemode = $decode['data']['topStats']['mapMode'];
But if anyone know a better way, please, tell me.
Since the items in the list doesn't have a "name", unlike "data" & "mainWeaponStats", I can't really figure out how to do this.
Edit:
This is the relevant code so far:
$weaponstats = "http://battlelog.battlefield.com/bf3/weaponsPopulateStats/" . $bf3id . "/1/";
$content = file_get_contents($weaponstats);
$decode = json_decode($content, true);
$mainweaponstats = $decode['data']['mainWeaponStats'];
As you can see, I'm having a hard time learning Json.
I'm trying to read up on it, but as of now, I can't figure this out.
I don't really know how I'm going to do it, as the values I'm trying to find are within the same group.
$mainweaponstats = $decode['data']['mainWeaponStats'];
This is an array of objects (well arrays because you passed ,true to json_decode). Just loop through this and find what you want.
$search = 'Underslung Launcher';
$kills = 0;
foreach($mainweaponstats as $w){
if($w['name'] === $search){
$kills = $w['kills'];
break;
}
}
echo $kills;
<?
$name = "Underslung Launcher";
$json = file_get_contents("json.php");
$dec = array();
$dec = json_decode($json,true);
$datas = $dec['data']['mainWeaponStats'];
foreach($datas as $data)
{
if($data['name']==$name) {
echo $data['kills'];
break;
}
}
?>
