I have a problem to get the value from json data inside array when the data is more than one.
When my data only one like this:
$mydata='[{"firstName":"Ana","height":5.3}]';
I can just access the height of Ana by substring-ing it first and the decode it, like this:
$mydata= substr($mydata, 1, -1);
$obj = json_decode($mydata);
print $obj->{'height'};
The problem is when the data look like this:
$mydata='[{"firstName":"Ana","height":5.3},{"firstName":"Taylor","height":5.11}]';
How can I get the height of Ana?
print $obj->{0}->{'height'}; //doesn't work.
Please help. Thankyou in advance.
use json_decode
$b_arr=json_decode($mydata,true);
$b_arr[0]['height'];//0 is index for array
You can convert with json_decode and iterate through your array to get your specific data:
<?php
$mydata='[{"firstName":"Ana","height":5.3},{"firstName":"George","height":7.3}]';
$json = json_decode($mydata, true);
foreach($json as $key => $value) {
if($value['firstName'] == 'Ana') {
echo $value['height'];
break;
}
}
?>

I have some issue with a decoded Json object sended to a php file. I have tried some different format like this
{"2":"{Costo=13, ID=9, Durata_m=25, Descrizione=Servizio 9}","1":"{Costo=7, ID=8, Durata_m=20, Descrizione=Servizio 8}"}
or this.
[{"Costo":"7.5","ID":"3","Durata_m":"30","Descrizione":"Barba Rasoio"},{"Costo":"4.5","ID":"4","Durata_m":"20","Descrizione":"Barba Macchinetta"}]
In order the first, any suggestions helps me, then i have converted previous string using GSON, however php doesn't decode.
This is my php:
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data['servizi'] as $key => $value)
{ echo "Key: $key; Value: $value<br />\n";
}
How can I access single elements of array? What I'm doing wrong? Thanks in advance
I think you should check the content in this way
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data as $key => $value) {
echo "FROM PHP: " . $value;
echo "Test : " .$value['ID'];
}
your elements of {Costo=7, ID=8, Durata_m=20, Descrizione=Servizio 8}
are not properly formated as an array element. That is a pure string and not an array value.
This is a json object with 1 element of array:
{
"1": {
"Costo": 7,
"ID": 8,
"Durata_m": 20
}
}
The Inside are json objects. Therefore your json string was not properly formated to operate with that logic. What you had was an element of a string. That is the reason why it was a valid json (passing jsonlint) but was not the correct one that you wanted to use.
UPDATE
Because this format is fix, I have a non-elegant way:
//Receive JSON
$JSON_Android = $_POST["JSON"];
//Decode Json
$data = json_decode($JSON_Android, true);
foreach ($data as $key => $value) {
//to separate each element
$newArray = explode(',',$value);
$newItem = explode('=', $newArray[1]);
echo "ID". $newItem[1];
}
That would be the dirty way to do it ONLY IF THE PLACEMENT OF DATA IS FIX. (ie the second element of the first explode is always ID.
I will leave it to someone else to make the suggested code better. I would recommend more to ensure that the json you are receive is proper because as I explained, it is incorrectly formated and as an api developer, you want an adaptive way for any given client to use the data efficiently.
below is my 'script.json' file with json array and i want the values of webUserid and webPassword
{
"totalSize":2,
"webUserId":"abc",
"webPassword":"def",
"operation":"send",
"testMode":true,
"records":[
{
"phoneNumber":"1908908399",
"message":"Happy Birthday",
"Id":"a0YL0000008QYunMAG",
"deviceId":"ABCDEFXABCDEF"
}
]
}
I tried below one but not getting the result
<?php
$jsonString=file_get_contents("script.json");
$decoded=json_decode($jsonString,true);
foreach($decoded->data as $name){
echo $name->totalSize;
}
?>
Zarif, try the below code, its working 100%......... :)
<?php
$jsonString=file_get_contents("script.json");
$decoded=array(json_decode($jsonString,true));
foreach($decoded as $name){
echo $name['totalSize'];
}
?>
There's no need for a foreach loop in your current example, as you only have one level.
Your main problem is you're trying to use the result of your json_decode as an object when you've previously stated you want the result as an associative array.
The 2nd param of json_decode specifies what format the return value is in, so as you've done
$decoded = json_decode($jsonString, true);
you'll receive an array, which you could access like
echo $decoded['totalSize'];
if you wanted to treat it as on object as you've done in your question, either state false or omit a 2nd param in json_decode (it's false by default anyway), and that'll let you do what you're trying to do:
$decoded = json_decode($jsonString);
$decoded->totalSize;
lets say that
$myJSON = yourPostedJSON.
$myJSON = json_decode($myJSON, true);
echo $myJSON['webUserId'];
echo $myJSON['webPassword'];
I've have this list of products in JSON that needs to be decoded:
"[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]"
After I decode it in PHP with json_decode(), I have no idea what kind of structure the output is. I assumed that it would be an array, but after I ask for count() it says its "0". How can I loop through this data so that I get the attributes of each product on the list.
Thanks!
To convert json to an array use
json_decode($json, true);
You can use json_decode() It will convert your json into array.
e.g,
$json_array = json_decode($your_json_data); // convert to object array
$json_array = json_decode($your_json_data, true); // convert to array
Then you can loop array variable like,
foreach($json_array as $json){
echo $json['key']; // you can access your key value like this if result is array
echo $json->key; // you can access your key value like this if result is object
}
Try like following codes:
$json_string = '[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]';
$array = json_decode($json_string);
foreach ($array as $value)
{
echo $value->productId; // epIJp9
echo $value->name; // Product A
}
Get Count
echo count($array); // 2
Did you check the manual ?
http://www.php.net/manual/en/function.json-decode.php
Or just find some duplicates ?
How to convert JSON string to array
Use GOOGLE.
json_decode($json, true);
Second parameter. If it is true, it will return array.
You can try the code at php fiddle online, works for me
$list = '[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]';
$decoded_list = json_decode($list);
echo count($decoded_list);
print_r($decoded_list);
With fetchAll(PDO::FETCH_ASSOC) get such array
$array =
Array
(
[0] => Array
(
[FinalCurrencyRate] => 0.000062
)
)
Need to json_encode to use in
$.post("__02.php", { 'currency': currency }, function(data, success) {
$('#currency_load').html(data.FinalCurrencyRate);
$('#currency_load0').html(data.FinalCurrencyRate0);
$('#currency_load1').html(data.FinalCurrencyRate1);//and so on
}, "json");
If simply echo json_encode($array); then does not work.
Need to convert to json format array like this:
$arr = array ('FinalCurrencyRate'=>"0.000062");
To convert to json format, wrote such code
$json_array = "{";
$flag_comma = 0;
foreach($array as $i =>$array_modified) {
if ($flag_comma == 0) {
$json_array .="'FinalCurrencyRate". $i."'=>'". $array_modified[FinalCurrencyRate]. "'";
$flag_comma = 1;
}
else {
$json_array .=", 'FinalCurrencyRate". $i."'=>'". $array_modified[FinalCurrencyRate]. "'";
}
}
$json_array .= "}";
Then echo json_encode($json_array);. And only one echo json_encode.
But does not work.
Understand that there are errors in code to convert to json format. What need to correct, please?
If I understand correctly you just want to return the first row form your array, then you just need to do this
echo json_encode($array[0]);
UPDATE
I think I see what you're trying to do now, you're trying to append the index to the FinalCurrencyRate key in each row. No need to do that, what you should do is change your javascript code to look like this:
$('#currency_load0').html(data[0].FinalCurrencyRate);
$('#currency_load1').html(data[1].FinalCurrencyRate);//and so on
My JSON looks like this. How do I get a specific field, e.g. "title" or "url"?
{
"status":1,
"list":
{
"204216523":
{"item_id":"204216523",
"title":"title1",
"url":"url1",
},
"203886655":
{"item_id":"203886655",
"title":"titl2",
"url":"url2",
}
},"since":1344188496,
"complete":1
}
I know $result = json_decode($input, true); should be used to get parsable data in $result, but how do I get individual fields out of $result? I need to run through all the members (2 in this case) and get a field out of it.
json_decode() converts JSON data into an associative array. So to get title & url out of your data,
foreach ($result['list'] as $key => $value) {
echo $value['title'].','.$value['url'];
}
echo $result['list']['204216523']['item_id']; // prints 204216523
json_decode() translates your JSON data into an array. Treat it as an associative array because that's what it is.
