I'm trying to print a value from a object array, but I'm facing some problems. I want to echo in php the value of [title] but i am not getting it!
stdClass Object (
[result] => success
[records] => stdClass Object (
[500272328] => stdClass Object (
[nif] => 500272328
[pc4] => 2775
[pc3] => 372
[seo_url] => solnave-restaurantes-e-alimentacao-s-a
[title] => Solnave - Restaurantes e Alimentação S.a
[city] => Cascais
[racius] => http://www.racius.com/solnave-restaurantes-e-alimentacao-s-a/
[portugalio] => http://www.portugalio.com/solnave-restaurantes-e-alimentacao-sa-2/
)
)
)
How can i retrieve?
Thank you!
I am assuming you are calling json_decode to decode the JSON string.
You should call it as json_decode($thestring_to_be_decoded, true). This will convert the objects to associative arrays and you will be able to access the title field.
Your stdClass is a PHP object or a Javascript encoded object?
It seems a PHP, so to echo title element you must navigate at there:
echo $yourobjarray->records->500272328->title;
or
echo $yourobjarray->records->500272328['title'];
(not evident in your question)
But to echo into <script> section of a HTML page,
<script> ...
var x='<?= $yourobjarray->records->500272328['title'];?>';
...</script>
and, if a AJAX context, to JSON response you need
echo json_encode($x);
where $x is your array or the title string, or what you want.
You can make use of a foreach construct to loop through your JSON decoded object array or If you want to print individual elements you can simply do like this.
echo $yourobjarray->result; //"prints" success

I've experienced a problem when developing for a minecraft server: I have an array like this which is received as json and encoded but for processing the output of this I need to know how to access the array and echo one of the values for Example the Version Key.I tried to save the array as variable $json and to access it via echo $json->Version; but this results in the output of this error: Notice: Trying to get property of non-object in /home/bs-web/joomla/api/test2.php on line 12
Here´s the Array:
Array
(
[0] => stdClass Object
(
[GameName] => MINECRAFT
[Version] => 1.8
[Plugins] =>
[Map] => BungeeCord_Proxy
[Players] => 7
[MaxPlayers] => 100
[HostPort] => 25565
[HostIp] => 188.40.97.86
[Software] => Vanilla
)
)
Your variable $json is an array, you cannot get property of an array. Assuming you have only one element in the array as in your example, you should use
echo $json[0]->Version;
to display the version(1.8 in your example).
once you saves the $json variable as an array, you only can access its values passing the key that you want to use, and then, point to the object. In your case, to get the Version property, you will need to use $json[0]->Version.
To access and echo all values of your object you can use a foreach loop to iterate with it.
foreach ($json as $object){
echo $object->GameName;
echo $object->Version;
echo $object->Plugins;
.... // All properties that you want
}
Hope it helps you, hugs.
You could also use json_decode($json, true) then you get an assocative array which you can access like this $json['Version']
I am very basic new php learner, i having difficulty to get nested array value, here is my json result:

I can access the Title, but can't access the Link urls:
echo $title = $json->{'title'};
echo $link = $json->{'link'}->{'22'}->{'0'};
How can access the specific link array 22
This echo $title = $json->{'title'}; works because you are accessing an object's property and using -> is the correct way.
In this case $json->{'link'}->{'22'}->{'0'} you are trying to access an array item instead an object's property, because $json->{'link'}->{'22'} is an array and not an object. In this case, you should access it in this way: $json->{'link'}->{'22'}[0]. In order to avoid this kind of issues and, when you decode your JSON to a PHP object, you can pass true as a second parameter to the function json_decode and that will convert the whole object into an array. That way, you don't need to worry about accessing elements as object's attributes, you can access them, always, as array items. So, in this case, it would be: $json["link"]["22"][0].
You're confusing the way you access objects and arrays.
Getting the title is correct via $json->title, but the link should be $json->link->{'22'}[0] - a mixture of objects and arrays.
FYI the {'name'} notation is the same as name - only required when you are including variables in your object name e.g. {$someVar . 'name'}
I suppose you use json_decode() function. Do you know that you can get an array instead of StdClass Object? So, you can use.
<?php
$php_array = json_decode($json_string, true);
I am using $this->db->get_where() to get data from database in codeigniter.
Its returning following which I got using print_r()
Its looks like array of stdClass object. Anyone who how to access values inside this array.
Array ( [0] =>
stdClass Object (
[id] => 1
[password321] => qwerty
[email123] => example#gmail.com
[username123] => xyz
)
)
It shows an array of objects. There is only one object in it.
If:
$var = $this->db->get_where();
Then:
echo $var[0]->id;
Access it like any other object.
echo $array[0]->id //1
echo $array[0]->username123 //xyz
And so on. If you have multiple objects inside the array, run it through a for loop to iterate the array.
For example:
for ($i=0;$i<sizeof($array);$i++) {
echo $array[$i]->[object property];
}
Array
(
[0] => Array
(
[price_id] => 1
[website_id] => 0
[all_groups] => 1
[cust_group] => 32000
[price_qty] => 2
[price] => 90.0000
)
[1] => Array
(
[price_id] => 2
[website_id] => 0
[all_groups] => 1
[cust_group] => 32000
[price_qty] => 5
[price] => 80.0000
)
.......
)
the array element maybe one or two or more, if i want to pass [price_qty] and [price] value to the jquery code. how should i do? could someone make me an example. thank you
you should consider using JSON strings in order to use key based arrays in JavaScript.
http://php.net/json
json_encode your php arrays to json
Use json_encode to convert your php array to json :)
A possible solution is to convert php array structures into JSON before passing the data to the client.
Have a look at php json.
And also have a look at this post.
Try with Json:
json_encode($array);
This will encode the array into a json object, that is friendly with javascript (and Jquery).
If you are passing it through an ajax request just echo it in the php and return that as response.
If it's in the same script you could do:
$object = json_encode($array);
echo "var myObject = $object;";
And for accessing the information in javascript/jquery you would do:
alert(myObject[0].price_id);
you use myObject[0] to access positions as in php arrays, and myObject[0].name to access what would be associative array key in an array.
For more information visit json documentation page
Well while you ask to move from [php]array to [javascript]array, this is how to. You should ue json_encode how the previous answer said, but in you javascript you can use the following code to convert a json into an array:
function json2Array = function(json){
var a = [];
for(var o in json){
a.push(json[o]);
}
return a;
}
var myArray = json2Array(youPhpJsonEncode);
and you will have your array in javascript
I have an array called $results, when I use function:
print_r($results);
I get the following.
Array
(
[0] => ProfileElement Object
(
[name] => John thomson
[email] => johnt#gmail.com
[Bio] => 20 years of engineering expertise
[url] => http://twitter.com
)
)
My goal is to echo [name] [email] [Bio] [url] values separately. But when I write the following code in php I don't get any values?
echo $results[0]["ProfileElement Objects"]["Bio"];
Does anyone know why? Isn't this an array inside an array?
It appears that the array element contains an object, not another array. To access the object property, use the -> operator:
echo $results[0]->Bio;
You were close.
echo $results[0]->bio;
Is probably what you want. $result[0] is an object.
Also, depending on visibility, you may need to use a getter method.
remove ["ProfileElement Objects"]
echo $results[0]->Bio;
Try doing:
$results[0]->name;
ProfileElement Object is the object type.
It's an object inside an array. It looks like you should be able to access it as $results[0]->name, $results[0]->email, etc.
It is an object. You can get the 'Bio' value using:
echo $results[0]->Bio;
