I have a JSON object key element that i want to delete.
Lets say i want to delete the element of everything inside 'v8fe3m'
I tried using unset and delete. Nothing seems work unless my syntax is wrong.
{
"projects": {
"587ye4": {
"name": "abc",
"ip": "zz",
"loc": "azz"
},
"v8fe3m": {
"name": "japan",
"ip": "aaa",
"loc": "123",
"backups": {
"HELLO_1595524710053": {
"ts": 1595524710053,
"name": "HELLO",
"size": 770641
},
"HELLO_1595524717330": {
"ts": 1595524717330,
"name": "HELLO",
"size": 770641
},
"HELLO_1595524717558": {
"ts": 1595524717558,
"name": "HELLO",
"size": 770698
}
}
},
"x0190a": {
"name": "dubai",
"ip": "101",
"loc": "UAE"
}
}
}
$user_token = $_SESSION["userToken"];
$user_projects_json = read_json($GLOBALS['URL_JSON'] . "$user_token" . "_projects" .".json");
$projectKey = $_REQUEST['dataKey'];
$projectKey = trim($projectKey," ");
//v8fe3m
$backups = $user_projects_json['projects'][$projectKey];
unset($backups);
Since PHP is a strange language, it copies objects. Therefore $backups is a copy of $user_projects_json['projects'][$projectKey].
$backups = $user_projects_json['projects'][$projectKey];
unset($backups); //You are unsetting a very new object.
You can do
$backups = &$user_projects_json['projects'][$projectKey];
unset($backups); //You are unsetting a reference that refers to your object.
This way $backups are referring to your original object, thus unsetting what you need. I saw someone did it in the comments, but there were no explanation, unsetting without creating a new object.
First use $arrayFromJson = json_decode($yourJsonObject, true);, then you can use standard PHP array functions such as:
unset($arrayFromJson['v8fe3m']);

I am programming a adminpanel with charts etc. Now I want to access a collection but before i can do that I need to know the name of the collection. So I can use that in the method itself
this is the snippet
{
"335": [],
"338": [
{
"id": 114,
"uuid": "",
"creator": null,
"ip": "",
"version": 338,
"time": "1526806163720"
},
{
"id": 115,
"uuid": "",
"creator": null,
"ip": "",
"version": 338,
"time": "1526806269412"
}
],
"340": [],
"389": [],
"393": [],
"401": [],
"404": []
}
As you can see every collection that is in this collection has a name.
When I am using this piece of code it doesnt give me a way to get to the name to use it in the switch statement.
foreach ($toConvert as $convert) {
switch ($convert) {
Does anyone know if this can be done or is this a limitation of laravel 5.7?
Use:
foreach ($toConvert as $name => $convert) {
switch ($name) {
...
The second form will additionally assign the current element's key to the $key variable on each iteration.

I really need help on this one.
I have the following Json Schema:
{
"url": "http://www.google.com",
"bodySchema": {
"type": "object",
"properties": {
"SKU": {
"sync": "True",
"mapTo": "SKU",
"type": "string"
},
"WareHouseId": {
"sync": "False",
"mapTo": "",
"type": "integer"
},
"Stock": {
"sync": "True",
"mapTo": "Stock",
"type": "integer"
}
},
"required": {
"0": "SKU",
"1": "Stock"
}
}
}
I would like to retrieve all elements and check if they are required or not,
On the first part (Getting all elements)
What I'm doing is:
foreach ($this->methods as $data) {
if(!empty($data['bodySchema']->properties)){
}
}
But my problem is that I have no way to get the SKU, WarehouseID or Stock, because it's not a key nor anything of the kind.
For my second issue what I was thinking, was to put all required as string and do a loop through them, but if there is any alternative would be glad to know.
You can get the properties out with a simple loop:
foreach ($data->bodySchema->properties as $key => $value) {
// ..
}
If you want to add the required field to the results from above, you can do it like so:
foreach ($data->bodySchema->required as $required) {
$data->bodySchema->properties->$required->required = true;
}
Example with objects or with arrays.

I tried using below code,
it doesn't work.
$json = json_decode($body);
echo $json->ISBN:9780980200447->info_url;
It's giving an error..
Is there any other easy way to read all elements?
You are on the right track. : is just an invalid character for a property and must be handled special.
echo $json->{'ISBN:9781430215752'}->info_url;
will get you the expected result.
You may also decode as an associative array
$json = json_decode($body, true);
echo $json['ISBN:9781430215752']['info_url'];
I would probably stick to this approach rather than the object oriented, since encapsulating keys makes code less readable
You must use
echo $json->{'ISBN:9780980200447'}->info_url;
since 'ISBN:9780980200447' is your class name.
Reference: php.net
<?php
$json = '{"foo-bar": 12345}';
$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345
?>
Use braces like this:
echo $json->{'ISBN:9781430215752'}->info_url;
I a trying to decode a json callback.
The json code is posted to callback.php - Here is an example of the json:
{
"order": {
"id": "5RTQNACF",
"created_at": "2012-12-09T21:23:41-08:00",
"status": "completed",
"total_btc": {
"cents": 100000000,
"currency_iso": "BTC"
},
"total_native": {
"cents": 1253,
"currency_iso": "USD"
},
"custom": "order1234",
"receive_address": "1NhwPYPgoPwr5hynRAsto5ZgEcw1LzM3My",
"button": {
"type": "buy_now",
"name": "Alpaca Socks",
"description": "The ultimate in lightweight footwear",
"id": "5d37a3b61914d6d0ad15b5135d80c19f"
},
"transaction": {
"id": "514f18b7a5ea3d630a00000f",
"hash": "4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b",
"confirmations": 0
},
"customer": {
"email": "coinbase#example.com",
"shipping_address": [
"John Smith",
"123 Main St.",
"Springfield, OR 97477",
"United States"
]
}
}
}
I can echo the json and get the following response:
{"order""id":null,"created_at":null,"status":"completed","total_btc":{"cents":100000000,"currency_iso":"BTC"},"total_native":{"cents":83433,"currency_iso":"USD"},"custom":"123456789","receive_address":"1A2qsxGHo9KjtWBTnAopTwUiBQf2w6yRNr","button":{"type":"buy_now","name":"Test Item","description":null,"id":null},"transaction":{"id":"52d064b59eeb59985e00002c","hash":"4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b","confirmations":0}}}
However if I try to decode the json using the following:
$array = json_decode($jsonString, true);
echo $array;
I get the following response: "200 Array"
I want to be able turn each json parameter in to a php variable.
You can access the variables within $array, for example by doing:
echo $array['custom']; // prints out "order1234"
You don't want to extract the variables directly into the local lexical scope of your program as that would create security concerns. Just use the data as indicated in the snippet above.
I have the following url:
https://graph.facebook.com/123456/likes?access_token=__ACCESS_TOKEN__&format=json
which I then do:
$likesList = json_decode(file_get_contents("https://graph.facebook.com/123456/likes?access_token=$access_token&format=json"),true);
which produces e.g.
{
"data": [
{
"name": "yo yo yo",
"category": "Entertainer",
"id": "45640987076",
"created_time": "2012-04-18T16:14:09+0000"
},
{
"name": "Tony Smith",
"category": "Musician/band",
"id": "456456456456",
"created_time": "2012-02-22T06:56:18+0000"
},
{
"name": "Stations",
"category": "Company",
"id": "567657567",
"created_time": "2012-01-30T23:08:39+0000"
}
]
}
and I then want to list e.g. all the names returned so:
foreach ($likesList->data as $element2){
$name = $element2[name];
echo $name;
}
But it's empty?
See this visualization of your data structure.
As you are receiving an array, you need $list["data"] and not $list->data. Also don't forget to quote the array key "name".
foreach ($likesList['data'] as $element2){
$name = $element2['name'];
echo $name;
}
After json_decode with parameter true you will have associative array. You can access to value by string key. Like in example above.
