PHP Printing JSON value - php

I have a JSON array that I want to be able to drill down to a lower level and print just that value. The problem occurs when I reach a level that has is indacted as [0] (or [n]). For example I have the following output, and I want to just print the game key for the first league.
This is how I am trying to print it
HtmlSpecialChars(print_r($user->fantasy_content->users[0]->user[1]->games[0]->game[0]->game_key,1))
However I keep getting this error:
Cannot use object of type stdClass as array
When I do it incrementally it seems to fail on this command (so I assume I'm not index correctly):
$user->fantasy_content->users[0]
Here is the output:
stdClass Object
(
[fantasy_content] => stdClass Object
(
[xml:lang] => en-US
[yahoo:uri] => /fantasy/v2/users;use_login=1/games
[users] => stdClass Object
(
[0] => stdClass Object
(
[user] => Array
(
[0] => stdClass Object
(
[guid] => IYEZUHTVBYRLIB3OAQC5WRZPQY
)
[1] => stdClass Object
(
[games] => stdClass Object
(
[0] => stdClass Object
(
[game] => Array
(
[0] => stdClass Object
(
[game_key] => 147
[game_id] => 147
[name] => Baseball
[code] => mlb
[type] => full
[url] => http://baseball.fantasysports.yahoo.com/b1
[season] => 2006
)
)
)
[count] => 1
)
)
)
)
[count] => 1
)
[time] => 52.390813827515ms

[refresh_rate] => 60
)
)

For objects you must use the -> syntax and if the key/property name is a number or has other special characters, you will need to use the $object->{'0'} syntax.
The game_key can be retrieved using:
$user->fantasy_content->users->{'0'}->user[1]->games->{'0'}->game[0]->game_key;

You can convert a stdClass object to an array by casting it like so:
<?php
$array = (array) $myObject;
echo json_encode($array);
You can also cast inline:
<?php
echo json_encode((array) $object);

how get value feild[ID] stdClass Object in php code

how get value feild[id] in php code
stdClass Object ( [List_inserted] => Array ( [0] => stdClass Object ( [ID] => 145001 [value] => 40 ) ) [Sucssess] => 1 [ErrorMassage] => OK )
You didn't give us a name of stdClass so I'm assuming it's $stdClass.
$stdClass->List_inserted[0]->ID
Let's break it down;
stdClass Object ( [List_inserted] => Array ( [0] => stdClass Object ( [ID] => 145001 [value] => 40 ) ) [Sucssess] => 1 [ErrorMassage] => OK )
We access objects with a -> and we access arrays with []
The first part tells us it's an object, so it's;
$stdClass->List_inserted
List_inserted is an array thanks to the => Array. We can access this with [0].
$stdClass->List_inserted[0]
Well, List_inserted[0] is an object, thanks too [0] => stdClass Object; and you wanted to access the ID? So we need another ->
$stdClass->List_inserted[0]->ID

PHP - Changing an Object for Consistency

I have a scenario where an API is returning multiple records inside object containing a numeric array like so;
stdClass Object
(
[Event] => Array
(
[0] => stdClass Object
(
[ID] => 111
[Name] => My First Event
[EventType] => stdClass Object
(
[ID] => 1
[Category] => Music
)
)
[1] => stdClass Object
(
[ID] => 222
[Name] => My Second Event
[EventType] => stdClass Object
(
[ID] => 2
[Category] => Sport
)
)
)
[Errors] => stdClass Object
(
[Result] => 0
[Message] =>
)
[RecordCount] => 2
)
I'm current using a foreach loop to iterate through the records. This works fine.
foreach($result->Event as $Event)
But there is a problem here I have a scenario where a single results is returned in the object like so;
stdClass Object
(
[Event] => stdClass Object
(
[ID] => 11
[Name] => My Only Event
[EventType] => stdClass Object
(
[ID] => 2
[Category] => Sport
)
)
[Errors] => stdClass Object
(
[Result] => 0
[Message] =>
)
[RecordCount] => 1
)
Notice there is no [0] array index for the single results.
What's the best way to overcome this keeping in mind that I have no control of the data returned by the API?
Check if Event is an array or an object
if( is_object( $result->Event ) )
{
// ...
}
else
{
foreach( // [....]
}
You may process the object or overwrite it with a 1 item array as suggested by Sam
Btw: very bad API design. I would complain....
The best workaround I have found is to add the single Event to an array with a zero index within the result object. This way the result object matches the same structure as a result containing multiple records.
if(!is_array($result->Event)){
$result->Event = array($result->Event);
}

Access data in an array

What I want to do is read the information and be able to get the data of each game, so which teams played, who won and etc. I've tried everything but can't seem to do this.
This is my data structure:
stdClass Object (
[_links] => Array (
[0] => stdClass Object (
[self] => http://api.football-data.org/alpha/soccerseasons/354/fixtures
)
[1] => stdClass Object (
[soccerseason] => http://api.football-data.org/alpha/soccerseasons/354
)
)
[count] => 10
[fixtures] => Array (
[0] => stdClass Object (
[_links] => stdClass Object (
[self] => stdClass Object (
[href] => http://api.football-data.org/alpha/fixtures/137842
)
[soccerseason] => stdClass Object (
[href] => http://api.football-data.org/alpha/soccerseasons/354
)
[homeTeam] => stdClass Object (
[href] => http://api.football-data.org/alpha/teams/338
)
[awayTeam] => stdClass Object (
[href] => http://api.football-data.org/alpha/teams/70
)
)
[date] => 2015-01-17T15:00:00Z
[status] => FINISHED
[matchday] => 22
[homeTeamName] => Leicester City
[awayTeamName] => Stoke City FC
[result] => stdClass Object (
[goalsHomeTeam] => 0
[goalsAwayTeam] => 1
)
)
[1] => stdClass Object (
[_links] => stdClass Object (
[self] => stdClass Object (
[href] => http://api.football-data.org/alpha/fixtures/136840
)
[soccerseason] => stdClass Object (
[href] => http://api.football-data.org/alpha/soccerseasons/354
)
[homeTeam] => stdClass Object (
[href] => http://api.football-data.org/alpha/teams/72
)
[awayTeam] => stdClass Object (
[href] => http://api.football-data.org/alpha/teams/61
)
)
[date] => 2015-01-17T15:00:00Z
[status] => FINISHED
[matchday] => 22
[homeTeamName] => Swansea City
[awayTeamName] => Chelsea FC
[result] => stdClass Object (
[goalsHomeTeam] => 0
[goalsAwayTeam] => 5
)
)
)
)
For example: I'd like to know what the value for "homeTeamName","awayTeamName", "goalsHomeTeam", "goalsAwayTeam" ...
Its hard to tell because you didnt post the code you are using but i suspect you are confusing the structure type. What you posted is actually an object - an instance of stdClass and the items that look like array elements are in fact properties on that object. So you need to use the appropriate access method of ->propertyName as opposed to ['propertyName']:
// YES
echo $data->fixtures[0]->homeTeamName;
// NO
echo $data['fixtures'][0]['homeTeamName'];
So to get the data for each game (or what i presume to be the "game" items) you would do:
foreach ($data->fixtures as $game) {
echo $game->homeTeamName;
echo $game->awayTeamName;
echo $game->result->goalsHomeTeam;
echo $game->result->goalsAwayTeam;
// etc..
}
It also seems like this is the return value from an API parsed with json_decode(). If that is the case you can actually make it an array all the way through by passing true as the second argument to json_decode():
$data = json_decode($response, true);
foreach ($data['fixtures'] as $game) {
echo $game['homeTeamName'];
echo $game['awayTeamName'];
echo $game['result']['goalsHomeTeam'];
echo $game['result']['goalsAwayTeam'];
// etc..
}

deseralize php Json in vb.net

I trying to get a array in VB.NET, but I have troubles for deserialize, I don't know if my format is bad or what, but first the data is a std object
Array
(
[0] => stdClass Object
(
[id] => 6797892
[marca] => xxx
[details] => yyy
[price] => rrr
[info] => Array
(
[0] => stdClass Object
(
[Items] => Array
(
[0] => stdClass Object
(
[Por] => 1
[$$hashKey] => 03F
)
)
[Tipo] => mouse
[price] => 1.65
[$$hashKey] => 03D
)
[1] => stdClass Object
(
[Items] => Array
(
[0] => stdClass Object
(
[Por] => o
[$$hashKey] => 03J
)
)
[Tipo] => teclado
[price] => 1.65
[$$hashKey] => 03H
)
)
[$$hashKey] => 03B
)
)
next i use json_encode(in php):result is:
[{"Id":"6797904","marca":"xxx","Pais":"yyy","Liga":"rrr","Jornada":"3","info":[{"Items":[{"Por":"1","Cuota":"2.25","$$hashKey":"03I"}],"Tipo":"mouse","price":2.25,"$$hashKey":"03G"}],"$$hashKey":"03E"}]
and using
....
file_put_contents($file, print_r($current, true) );
...
I save it in items.txt, and I load it in vb.net, but I don't know what is the correct way to convert into an array using:
Dim str As JArray = JArray.Parse(TextBox1.Text)
Dim results As Object = str("Id").ToString
To put in it an answer format.
The use of print_r is not correct here.
...
file_put_contents($file, print_r($current, true) );
...
The definition for print_r as per php.net:
print_r — Prints human-readable information about a variable.
This means extra characters are added to make it readable to humans, but not for machines. It even creates invalid JSON, causing VB.NET to generate an error.
Update your code to
...
file_put_contents($file,$current);
...
And it should work

PHP Access Object

I am new to Objects , and I've been playing with this little object. Now I would like to know how I can acess an specific element of it .
This is the object :
stdClass Object ( [responseHeader] => stdClass Object ( [status] => 0 [QTime] => 0 ) [response] => stdClass Object ( [numFound] => 1 [start] => 0 [docs] => Array ( [0] => stdClass Object ( [schoolname_s] => School of Art [schoolstate_s] => FL [schoolcity_s] => Miami [pk_id] => 111212 [schoolcountry_s] => United States [name_s] => Example ) ) ) )
I would like to print pk_id.
I have tried :
$phpArray->pk_id;
And this was the result:
Notice: Undefined property: stdClass::$pk_id in
You aren't accessing the right variable. What you want is this:
$phpArray->response->docs[0]->pk_id
