I have been trying to figure this out for a while now. Please any advice would be appreciated. I just need to access the array for ["Item"]. How do I gain access to this?
array(1) {
[0]=>
object(SimpleXMLElement)#16 (2) {
["#attributes"]=>
array(2) {
["Name"]=>
string(10) "AuthorList"
["Type"]=>
string(4) "List"
}
["Item"]=>
array(3) {
[0]=>
string(9) "Smith, Joe"
[1]=>
string(10) "Peter, Ann"
[2]=>
string(18) "Magoo, Mr"
}
}
}
Assuming this structure is in a variable called var1, you should be able to access Item using:
$var1[0]->Item // returns the array
I try to explain it.
Like you see, your first array index is an object.
If you see something like this in your var_dump than you can access it through deferencing the object.
It's the same like you would create an object and would like to access a public variable:
$var1 = new Object();
// when your Object variables are public so you could access them by deference the Object
echo $var1->myVariable; // will echo the public variable "myVariable"
So the answer from adam is the right one :)

I'm sending this JSON:
[{"tipo":""},{"activo":""},{"titulo":"Servicoasd B"},{"texto":"asdasdasd"}]
to a php file via post method.
There, i do
$obj = json_decode($_POST['sentJson']);
However, I seem to be unable to access the elements of the JSON.
var_dump(($obj));
Shows the object:
array(4) {
[0]=>
object(stdClass)#2 (1) {
["tipo"]=>
string(0) ""
}
[1]=>
object(stdClass)#3 (1) {
["activo"]=>
string(0) ""
}
[2]=>
object(stdClass)#4 (1) {
["titulo"]=>
string(9) "Servico B"
}
[3]=>
object(stdClass)#5 (1) {
["texto"]=>
string(6) "asdasd"
}
}
But if I try
$obj['texto'];
$obj->{'texto'};
$obj[0]['texto'];
$obj[0];
It shows "undefined index texto" or "trying to get property of non object in" and the last one "Object of class stdClass could not be converted to string in". I'm very new to PHP, but still I can't seem to notice what I'm doing wrong. Any help would be appreciated.
Your JSON is a serialized array of four completely different objects, so when you run json_decode, that's what you get: an array.
If you want to access your objects inside that array, access them like you would any other indexed array:
$list = json_decode(...);
foreach($list as $obj) {
var_dump($obj)
}
Or target them explicitly using plain old numerical access.
$list = json_decode(...);
$last = $list[3];
$text = $last->texto;
But really the question you should be asking is why this is the JSON you get. An array with completely different objects at each position is terrible data, and should be fixed.
I have finally managed to retrive data from mongoDB within PHP. How ever I am not able to retrieve single elements from this array looking. I can only vardump() the cursor. How is it possible to print single elements from this array that seems to be made up of objects?
object(stdClass)#11 (7) { ["_id"]=> object(MongoDB\BSON\ObjectID)#9 (1) { ["oid"]=> string(24) "5a4a2cf55ff0f310cbf1c3a4" } ["Category"]=> string(9) "Allgemein" ["DateAdded"]=> object(MongoDB\BSON\UTCDateTime)#10 (1) { ["milliseconds"]=> string(13) "1514810613331" } ["Name"]=> string(4) "Welt" ["Website"]=> string(11) "www.welt.de" ["Active"]=> bool(true) ["Country"]=> string(2) "DE" }
I couldnt find anything on goolgle or PHP/mongodb documentation. Why cant I just do $array["_id"]? And how can I retrieve _id for example?
The resource is an object of stdClass. So you need to use:
echo $array->_id;
In case, if you want to use arrays, use get_object_vars() function. That way:
$array = get_object_vars($array);
echo $array["_id"];
And then you can use objects as arrays.
I have a simple answer I just can't solution to:
var_dump(obj) =
object(stdClass)#15 (3) {
["properties"]=>
object(stdClass)#14 (2) {
["user_name"]=>
string(4) "somename"
["email_address"]=>
string(12) "test#test.com"
["arrays"]=>
object(stdClass)#17 (1) {
["sites[]"]=>
object(stdClass)#18 (4) {
["0"]=>
int(1)
["1"]=>
int(1)
["2"]=>
int(0)
["3"]=>
int(0)
}
}
}
How to call the 'sites[]' object in my 'obj'?
I tried the following:
obj->sites[]
obj->{'sites[]'}
Both options aren't working...
It might be better to clean up the code that generates that object, but you should be able to access the sites[] object via:
$sites = $obj->arrays->{'sites[]'};
However $sites will still be an object, so you would need to access its elements in a similarly awkward way:
echo $sites->{'0'};
It would be better to cast it to an array at that point:
$sites = (array) $obj->arrays->{'sites[]'};
Then you can access as an array:
echo $sites[0];
EDIT, seams you cannot access array elements indexed by a numerical string.
A better option (as discovered by a SO question i just posted about this) would be to use get_object_vars:
$sites = get_object_vars($obj->arrays->{'sites[]'});
Then you can access as an array:
echo $sites[0];
I cannot figure out to get these values from this array. I need to know the code and name so my application knows which one to go for but I can't get the values out of there. Can someone please help me out? It's the values in the #attributes.
I'm using PHP by the way.
Thanks

Using SimpleXML, you're able to access the attributes on an XML by using the elements as if it was an array ($xml->elementName['attributeName'], or using the ->attributes() method as previously given).
For example, given the following code:
$xml = new SimpleXMLElement('<root><item foo="bar"></item></root>');
If I wanted to access the foo attribute on the item element, I would access it like this:
echo $xml->item['foo'];
However, there's a catch: the value that is returned is actually an instance of SimpleXMLElement. To be able to store or use it, you will need to convert it to a primitive type:
echo (string)$xml->item['foo']; // now a string
echo (int)$xml->item['foo']; // now an integer
echo (bool)$xml->item['foo']; // now a boolean
I figured it out on my own.
$xmlResponse->AccessorialCharges->OtherAccessorialCharges[$i]['code'];
I got the following results in a object after I did a var_dump on that object, how can I access the individual elements and put them into a variable?
I tried:
$content["ID"];
$content->ID;
but no result :-(
["ID"]=>
string(5) "31655"
["Reference"]=>
string(7) "1899801"
["FullName"]=>
string(18) "Lennie De Villiers"
["Username"]=>
string(12) "lenniedg2000"
Try it on your end and see output
echo $content->ID;
$var=$content->ID;
echo $var;
Just take a look here I created an example
