I have a PHP standard class object converted from json_decode of a REST call on an API which looks like :
Array
(
[1437688713] => stdClass Object
(
[handle] => Keep it logically awesome.
[id] => 377748
[ping] => stdClass Object
(
[url] => https://api.me.com
[id] => 377748
[name] => web
[active] => 1
[events] => Array
(
[0] => data_new
[1] => data_old
)
So far i had no issues in parsing any of the PHP objects. However this one is failing because i can not access the nested object elements using a key since 1437688713 is not assigned to a key and accessing an object is failing if i try to do this:
$object->1437688713->handle
Is there a way to access these elements ?
Update: one more thing, i would never know this value (1437688713) in advance. Just like a key. All i get is a stdclass object which i have to parse.
The outer part of your data is an array, not an object. Try:
$array['1437688713']->handle;
or if you don't know the key, you can iterate over the array (handy if it may contain multiple objects too):
foreach ($array as $key => $object) {
echo $key; // outputs: 1437688713
echo $object->handle; // outputs: Keep it logically awesome.
}
Get the first item from $object array
$first_key = key($object);
Use it with your response array,
$object[$first_key]->handle;
Or, the first element of array
$first_pair = reset($object)->handle;

I am pulling an array from my DB that is saved in this format:
[categories] => [
{"category":"Exit Sign"},
{"category":"Leaving"},
{"category":"Illuminated"},
{"category":"Sign"},
{"category":"Red"},
{"category":"Warning Sign"},
{"category":"Above"}
]
How can I loop through each {} and get the category?
Edit: I have attempted passing each JSON array from my DB through json_decode() but I am getting the following error "json_decode() expects parameter 1 to be string, array given..." Any idea what would cause this?
Edit 2: Here is the var_dump output for just one row in my DB:
array(1) {
["categories"]=>
string(845) "[{"category":"Built Structure"},{"category":"The Americas"},{"category":"Sky"},{"category":"New York City"},{"category":"Manhattan - New York City"},{"category":"USA"},{"category":"History"},{"category":"Suspension Bridge"},{"category":"Brooklyn - New York"},{"category":"Brooklyn Bridge"},{"category":"Scenics"},{"category":"Skyscraper"},{"category":"River"},{"category":"Downtown District"},{"category":"East River"},{"category":"Cityscape"},{"category":"Bridge - Man Made Structure"},{"category":"City"},{"category":"Lighting Equipment"},{"category":"Arch"},{"category":"Urban Skyline"},{"category":"Architecture"},{"category":"Sunset"},{"category":"Night"},{"category":"Modern"},{"category":"Urban Scene"},{"category":"Tower"},{"category":"Famous Place"},{"category":"Gate"},{"category":"Outdoors"},{"category":"East"},{"category":"Travel"}]"
}
Got it! I had to pass $array['categories'] into json_decode and then it worked properly. Thanks everyone for your help!
Well, So you are new to this world. You are welcome.
Let your array value is names as $json. This value is a json format, so for access this value you need to decode them. You need to use a function called json_decode, which has two parameter, the first one is string where you pass your variable json, an second one is bool where you pass true or false.
You have to pass when you want your array as associative not object. Here i ignore the second option, so my return array is object.
After decoding your json string you have an array, now you have to use a loop foreach to browse all the elements of the array. As you can see in the resultant array below, the array is multi-dimensional so after applying a foreach loop you just reach the first depth. For getting the value of category you should need to use -> after $val which is the first depth array.
$json = '[{"category":"Exit Sign"},{"category":"Leaving"},{"category":"Illuminated"},{"category":"Sign"},{"category":"Red"},{"category":"Warning Sign"},{"category":"Above"}]';
$arr = json_decode($json); //Also you can pass $yourArr['categories'];
foreach($arr as $val){
echo $val->category."<br/>";
}
After decoding your array looks like:
Array
(
[0] => stdClass Object
(
[category] => Exit Sign
)
[1] => stdClass Object
(
[category] => Leaving
)
[2] => stdClass Object
(
[category] => Illuminated
)
[3] => stdClass Object
(
[category] => Sign
)
[4] => stdClass Object
(
[category] => Red
)
[5] => stdClass Object
(
[category] => Warning Sign
)
[6] => stdClass Object
(
[category] => Above
)
)
Result:
Exit Sign
Leaving
Illuminated
Sign
Red
Warning Sign
Above
I have this array called inputs:
Array ( [0] => InputValidation Object ( [array:InputValidation:private] => Array ( [Id] => demo1 [Required] => [MinLength] => 10 [MaxLength] => [RegexName] => [RegexMsg] => ) ) [1] => InputValidation Object ( [array:InputValidation:private] => Array ( [Id] => demo2 [Required] => [MinLength] => 20 [MaxLength] => [RegexName] => [RegexMsg] => ) ) )
I must get value Id, Required, MinLength, MaxLength, RegexName and RegexMsg. I have tried to foreach like this
foreach ($this->inputs as $input){
echo $input['Id'];
}
But it give me an error: Cannot use object of type InputValidation as array
How can I do? Thanks
inputs is an array in which the first element (index 0) is an object.
But in your loop, you try to echo an object property as if the object was an array.
Try:
foreach ($this->inputs as $input){
echo $input->Id;
}
Compared to JavaScript, objects in PHP cannot be accessed using the [] accessor, you have to use the -> accessor.
Yes I made a mistake.
Array inputs has 1st index with an object InputValidation.
This object also have a PRIVATE property named InputValidation (which is an associative array, where located the IdIindex you're looking for).
But this property is private. You won't be able to access it directly. You need a method on object InputValidation for that.
If that propery wasn't private but public, you woukd be able to access it as follow:
inputs [0]-> InputValidation-> InputValidation['Id'];
1st advice: avoid having an object which has a property with the same name than this object. That is confusing (I'd been trapped in it!)
2nd advice: read the doc about the objects you're using and PHP objects doc.
The advice from Comfreek looks like new feature in PHP or something that required well knowledge of it.
I can't seem to get specific data from an array inside an object.
$this->fields->adres gets the address correctly, but i can't get a level deeper.
I've tried:
$this->fields->province
$this->fields->province->0
$this->fields->province[0]
And: (edit)
$this->fields["province"][0]
$this->fields['province'][0]
$this->data->fields['province'][0]
But it does not return anything while it should return "Flevoland".
First part of the object print_r($this, TRUE) below:
RSMembershipModelSubscribe Object
(
[_id] => 2
[_extras] => Array
(
)
[_data] => stdClass Object
(
[username] => testzz
[name] => testzz
[email] => xxxx#example.com
[fields] => Array
(
[province] => Array
(
[0] => Flevoland
)
[plaats] => tesdt
[adres] => test
You can also use type casting.
$fields = (array) $this->data->fields;
echo $fields['province'][0];
As you can see by your output, object members are likely to be private (if you follow conventions, anyway you must prepend an underscore while calling them), so you're calling them the wrong way;
This code works:
$this->_data->fields['province'][0];
You can see it in action here;
I created a similar object, and using
$membership = new RSMembershipModelSubscribe();
echo $membership->_data->fields['province'][0];
outputs "Flevoland" as expected.
As fields is already an array, try this:
$this->fields['province'][0]
This assuming the [_data] object is $this.
Fields and province are both arrays, you should be trying $this->fields["province"][0]
$this->_data->fields['province'][0]
I have a stdclass object as shown below:
stdClass Object
(
[text] => Parent
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Laurence W. Lane Jr.
[url] => http://www.freebase.com/view/m/0c02911
)
)
)
I iterate over multiple such objects, some of which have
stdClass Object
(
[text] => Named after
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Stanford
[url] => SomeURL
)
)
)
I was wondering how I would access the "values" object if it comes after a "text" that has "Parent" as its value?
there are serveral ways to turn it to array:
First Solution:
$value = get_object_vars($object);
Second Solution:
$value = (array) $object;
Third Solution
$value = json_decode(json_encode($object), true);
to get value of converted array
echo $value['values']['0']['id'];
The alternate way to access objects var without convert the object, try
$object->values->{'0'}->id
Expanding (or rather minimalizing) upon answer by Somwang Souksavatd, I like accessing Object values like this:
echo get_object_vars($object)['values']['0']['id'];
I had the same issue, still not so sure why but I was able to get it working using this workaround:
$k2 ="1";
$elements = json_decode('{"id":"1","name":"User1"}');
//$elements['id'] == $k2; //****Not Working
$tmp = (object)$elements;
$tmp = $tmp ->id; //****Working
//$tmp =$elements['id'] ; //****Not Working
return $tmp == $k2;
I have to say that sometimes accessing the element as array works and some times not,(On PHP7 it worked for me but on PHP5.6 it didn't).
$elements can be Array to but I chose to demonstrate with json string.
I hope this helps somehow !!!
$Obj=stdClass Object
(
[text] => Named after
[values] => Array
(
[0] => stdClass Object
(
[id] => /m/0c02911
[text] => Stanford
[url] => SomeURL
)
)
)
$Values= $result->values;
$Item = $Values[0];
$id=$Item->id;
$text = $Item->text;
$url=$Item->url;
I'm doing the same thing and all I did was this;
<?php
$stdObject = json_decode($stdClassObject);
print $stdObject->values[0]->id;
this can help you accessing subarrays in php using codeigniter framework
foreach ($cassule['tarefa'][0] as $tarefa => $novo_puto_ultimos_30_dias) {
echo $novo_puto_ultimos_30_dias;
What you are looking for is the Object['values'][0]: 'values' is the keymap just like 'text', and [0] is the index inside that array you wish to access. so if you would like to get the id deep in the nest, you'd have to do something like
Object['values'][0]['id']
or
Object['values'][0]->id
which should give you /m/0c02911. But I have no idea how you are doing your loop, so you will have to adjust it to your needs and place proper variables where they need to go in that code in your loop. Not exactly sure which language you are working with.
I'm having a problem with SIMPLE XML. I seem to have an array with dumping the whole object. However, when I try to access the array, I get a single element of the array back.
Here is the full dump:
SimpleXMLElement Object
(
[#attributes] => Array
(
[type] => array
)
[person] => Array
(
[0] => SimpleXMLElement Object
(
..........................
),
[1] => SimpleXMLElement Object
(
..........................
)
)
)
when I try to access the person array through $xml->person, instead of getting the array, I get the first element back. Any ideas?
From the SimpleXML Basic usage documentation in the PHP Manual:
NOTE: Properties ($xml->movie in previous example) are not arrays. They are iterable and accessible objects.
So, in your case, $xml->person is not actually an array, just an iterable object. It can be easily converted to an array with:
$persons = array();
foreach ($xml->person as $person) {
$persons[] = $person;
}
