i have 1 json but i cant get a value using for loop
$string = [{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}]
$json = json_decode($string,true);
for($i = 0;$i<count($json);$i++){
for($j = 0;$j<count($json->lot);$i++){
if($json->lot==0){
echo $j;
}
}
}
i got this error : Trying to get property of non-object
edit your code :
$json = [{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}]
$json = json_decode($json);
for($i = 0;$i<count($json);$i++){
for($j = 0;$j<count($json->lot);$i++){
if($json->lot==0){
echo $j;
}
}
changes json to decode in array using php json_decode(). json_decode
You need to use json_decode on your json. Also, keep in mind that json have to be stored as string in PHP.
<?php
$json = ['{"lt":"1","lot":["1","1","1","1","1"]}','{"lt":"2","lot":["0","0","0","0","0"]}','{"lt":"3","lot":["0","0","0","0","0","0"]}'];
foreach($json as $data) {
$current = json_decode($data);
foreach($current->lot as $lot)
echo $lot;
}
Used json_decode() function for decode json :
<?php
$json = '[{"lt":"1","lot":["1","1","1","1","1"]},{"lt":"2","lot":["0","0","0","0","0"]},{"lt":"3","lot":["0","0","0","0","0","0"]}]';
$json = json_decode($json);
foreach($json as $val){
foreach($val->lot as $lot) {
if($lot==0){
echo $lot;
}
}
}
?>

I'm using iTunes RSS generator to get HOT tracks, now I'm using following way to parse JSON:
<?php
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'][0]['collectionName'];
echo $cltn;
?>
Now, as we know that It'll return only 1 collectionName.
JSON request is returning 10 results. How can I get them all using foreach loop? I've used several ways but no success.
Since you didn't give the output of the array I assume the [0] index is what needs to be iterated.
You need to foreach the $obj['feed']['results'] by doing:
Foreach($obj['feed']['results'] as $cltn){
Echo $cltn['collectionName'];
}
Foreach over the results:
foreach ($obj['feed']['results'] as $result) {
echo $result['collectionName'] . '<br>' . PHP_EOL;
}
Based on the code you provided you can iterate the results to get all possible information from the artist/track list, for example:
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'];
function test_print($item, $key)
{
echo "<strong>".$key."</strong>: ".$item."<br>";
}
foreach($cltn as $key => $c) {
echo "Result No ".($key+1)."<br>";
array_walk_recursive($c, 'test_print');
}
in case you only want to show artistName and collectionName you can slightly modify the above example:
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'];
foreach($cltn as $c) {
echo $c['artistName'].": ".$c['collectionName']."<br>";
}
You can try all the above in PHP Fiddle
Try like this way with foreach() to iterate your array in key=>value manner as you've decoded the json as an array not an object in php.
<?php
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$array = json_decode($jsondata,true);
# printing resulted array just for debugging purpose
print '<pre>';
print_r($array);
print '</pre>';
foreach($array['feed']['results'] as $key=>$value){
echo $value['collectionName'].'<br/>';
}
?>
I have a JSON with the Following structure.
{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}
I need the Itemname to be made into a PHP array, Unitprice into another one, Qty to another one and price to another one. How do I do that?
$getArray = get_object_vars(json_decode($json));
print_r($getArray);
echo $getArray[1]->Itemname;
echo $getArray[1]->unitprice;
you require get_object_vars as well for achieving your requirement.
<?php
$json =<<<JSONLIVES
{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}
JSONLIVES;
$items = json_decode($json, TRUE);
$item_names = array();
foreach($items as $key => $item) {
$item_names[] = $item['Itemname'];
}
Or Php >= 5.5
print_r(array_column($items, 'Itemname'));
You need a function called json_decode() to convert your json data into PHP array
$json = {
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
};
var_dump(json_decode($json));
You need to decode your Json by PHP's json_decode()
$decodeJson will return object then you can read Itemname and other values by using $val->Itemname in foreach loop
$json = '{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}';
$decodeJson = json_decode($json);
foreach($decodeJson as $key=>$val) {
print_r($val);
}
Live Json decode
Try that:
$json = json_decode($json);
foreach($json as $obj){
echo $obj->name;
.....
}
After some research, I found out that the most efficientt way that solves my problem here would be to do like the following.
$cash=json_decode($new_json, true);
echo $arr3[1]['Itemname'];
echo $arr3[1]['unitprice'];
:
:
and so on.
This can be put into loops easily, fetched into HTML text-fields (as I want here in this scenario) and so on.
i have the following JSON:
{"Switches":["Auswahl1","Auswahl2","Auswahl3"],"Check_MK":["Auswahl1","Auswahl2","Auswahl3"],"Testgroup":["Auswahl1","Auswahl2","Auswahl3"],"Printer":["Auswahl1","Auswahl2","Auswahl3"],"CAD":["Auswahl1","Auswahl2","Auswahl3"]}
How do i loop each object while using PHP?
My thoughts were the following:
<?php
$jsonfile = file_get_contents('tags.json');
echo $jsonfile . "<br><br>";
$decode = json_decode($jsonfile);
foreach($decode as $key => $value) {
echo $key . $value;
}
?>
Doesn't work..... Also
echo $decode[1];
and
echo $decode[1][1];
doesn't work..
You need to add a second parameter to json_decode()
This parameter returns associative array instead of existing object (if existing).
$decode = json_decode($jsonfile, TRUE);
This will convert your JSON decoded data into associative array.
$jsonfile = file_get_contents('tags.json');
echo $jsonfile . "<br><br>";
$decode = json_decode($jsonfile);
now $decode is equivalent to:
$decode = new stdClass();
$decode->Switches = array();
$decode->Switches[] = "Auswahl1";
$decode->Switches[] = "Auswahl2";
$decode->Switches[] = "Auswahl3";
$decode->Check_MK = array();
...
I have the following problem. When i am trying to read some json data that are posted from an html page, i'm facing with the following error "Trying to get property of non-object on line".
Jquery script to create the json
var json = {"data":[]};
json.data.push({serialNumber: $serialNumber, xreosi: $xreosiToPost,
forma: $forma, apolia: $apolia});
Jquery for posting to php
$.post("page.php",{jsonData: JSON.stringify(json),
customer: $("#cusID").val()},function(data){});
PHP file
$json = json_decode($_POST['jsonData']);
foreach($json as $value){
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
Thanks in advance.
Thereafter:
var json = {"data":[]};
json.data.push({serialNumber: $serialNumber, xreosi: $xreosiToPost,
forma: $forma, apolia: $apolia});
You have:
Object[data][0] = array('serialNumber' => ...);
Need:
$json = json_decode($_POST['jsonData'][0]);
or
$json = json_decode($_POST['jsonData']);
foreach($json as $row){
foreach($row as $value) {
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
}
json_decode without second parameter returns result as php object. You have to pass true as second parameter. Also your data are in $json['data'], not $json:
$json = json_decode($_POST['jsonData'], true);
foreach($json['data'] as $value) {
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
I send JSON object to server. On server side I have to parse this obj with PHP.
I'm stuck in the loop. I don't know how to proceed inside loops.
Im looking for most efficient way to parse this object and save all variables into DB.
[
{"ADI":{"id":-1,"danger":0}},
{"ADI":{"id":3,"danger":0}},
{"ADI":{"id":3,"danger":0}},
{"ALE":{"_id":1,"_name":"Milk","contain":false}},
{"ALE":{"_id":2,"_name":"cfg","contain":false}},
{"ALE":{"_id":4,"_name":"Lakt","contain":false}},
{"PRO":{"image":"","code":"123456","name":"jfbj"}},
{"USER":{"email":"spam#spam.com"}}
]
For now I have done this:
$string = file_get_contents('php://input');
$array = json_decode($string, true);
//print_r($array);
foreach ($array as $t => $index) {
foreach ($index as $vas => $r) {
//Here I'm stuck!!!
}
}
you can grab values from json
<?php
$string = '[
{"ADI":{"id":-1,"danger":0}},
{"ADI":{"id":3,"danger":0}},
{"ADI":{"id":3,"danger":0}},
{"ALE":{"_id":1,"_name":"Milk","contain":false}},
{"ALE":{"_id":2,"_name":"cfg","contain":false}},
{"ALE":{"_id":4,"_name":"Lakt","contain":false}},
{"PRO":{"image":"","code":"123456","name":"jfbj"}},
{"USER":{"email":"spam#spam.com"}}
]';
$array = json_decode($string, true);
echo "<pre>";
//print_r($array);exit;
for ($i=0;$i<=(count($array)-1);$i++){
//print_r($array[$i]);
if (array_key_exists("ADI",$array[$i])) {
$ArrVal = $array[$i]['ADI'];
$id = $ArrVal['id'];
$danger = $ArrVal['danger'];
echo "$id,$danger ";
}
}
?>
check this out :
echo "<pre>";
print_r($array);
for ($i=0; $i < count($array); $i++) {
if(isset($array[$i]["ADI"])){
print_r($array[$i]["ADI"]);
}
if(isset($array[$i]["ALE"])){
print_r($array[$i]["ALE"]);
}
}
echo "</pre>";
