Fetch & Print Multidimensional Stdclass Object Values using foreach loop
Its like a normal class object iteration. Please refer below example for more understanding and learn how to iterate Stdclass object foreach in php with following example block of code.
You may try the following code and execute at your end for multilevel arrays.
Let's create first multidimensional stdClass object for foreach loop demonstration
$student1 = new stdClass();
$student1->name = "John";
$student1->id = 123;
$student2 = new stdClass();
$student2->name = "Peter";
$student2->id = 321;
$students = array(
"math" => $student1,
"science" => $student2
);
$objects = (object) $students;
$objects will be generated as
stdClass Object
(
[math] => stdClass Object
(
[name] => John
[id] => 123
)
[science] => stdClass Object
(
[name] => Peter
[id] => 321
)
)
Loop through php stdClass object $objects example as below.
foreach($objects as $obj => $student){
echo "Department : " . $obj. " => Name: ". $student->name . " | id:" . $student->id ;
echo "<br>";
}
Output:
Department : math => Name: John | id:123
Department : science => Name: Peter | id:321
How to get stdclass object value in php for single dimensional object
// Single Dimensional Array
$employees = array(
'name' => 'Peter',
'age' => '21',
'address' => '123, wall street'
);
//Convert array to object
$obj = (object) $employees;
Now we have stdClass object as $obj as below
stdClass Object
(
[name] => Peter
[age] => 21
[address] => 123, wall street
)
Next let's see How to print stdClass object in php
echo "Name: ". $obj->name . " | Age:". $obj->age ." | Address:".$obj->address ;
Output: Name: Peter | Age:21 | Address:123, wall street
Therefore as per above code sample we can fetch value using $obj->paramName
How to extract stdClass object values from Mixed type Array?
Lets understand with following example code.
Creating multidimensional stdClass object for demonstration purpose.
$student1 = new stdClass();
$student1->name = "John";
$student1->id = 123;
$student2 = new stdClass();
$student2->name = "Peter";
$student2->id = 321;
$students = array(
"math" => $student1,
"science" => $student2
);
$objects = (object) $students;
$mixedArray = array(
"user" => array(
array(
'name' => 'Henry',
'age' => '24'
)
),
"students" => $objects
);
$mixedObjects = (object) $mixedArray;
Above Code will generate stdClass object as:
stdClass Object
(
[user] => Array
(
[0] => Array
(
[name] => Henry
[age] => 24
)
)
[students] => stdClass Object
(
[math] => stdClass Object
(
[name] => John
[id] => 123
)
[science] => stdClass Object
(
[name] => Peter
[id] => 321
)
)
)
Loop through stdClass Object $mixedObjects->students and render values as below
foreach ($mixedObjects->students as $obj => $student) {
echo "Department : " . $obj . " => Name: " . $student->name . " | id:" . $student->id;
echo "<br>";
}
Output:
Department : math => Name: John | id:123
Department : science => Name: Peter | id:321
