PHP Array convert from object and class
From w3cyberlearnings
create php object
<?php $employee_obj = new stdClass(); $employee_obj->name = 'Jamy Jo'; $employee_obj->age = 58; $employee_obj->address->street = '240 Lake Rd'; $employee_obj->address->apartment = '240'; $employee_obj->address->state = 'Tx'; $employee_obj->address->city = 'Houston'; $employee_obj->address->zip = '77300'; $employee_obj->role = 'PHP Developer'; print_r($employee_obj); ?>
Display Result
stdClass Object
(
[name] => Jamy Jo
[age] => 58
[address] => stdClass Object
(
[street] => 240 Lake Rd
[apartment] => 240
[state] => Tx
[city] => Houston
[zip] => 77300

[role] => PHP Developer

convert the php object to array
<?php $employee_obj = new stdClass(); $employee_obj->name = 'Jamy Jo'; $employee_obj->age = 58; $employee_obj->address->street = '240 Lake Rd'; $employee_obj->address->apartment = '240'; $employee_obj->address->state = 'Tx'; $employee_obj->address->city = 'Houston'; $employee_obj->address->zip = '77300'; $employee_obj->role = 'PHP Developer'; // convert to an array $my_array = (array) $employee_obj; print_r($my_array); ?>
Display Result
- The object converted to array, as you can see the address object is still PHP object.
- In order to convert all the objects within another object to array, you need to write a function to convert the object to array recursively.
Array
(
[name] => Jamy Jo
[age] => 58
[address] => stdClass Object
(
[street] => 240 Lake Rd
[apartment] => 240
[state] => Tx
[city] => Houston
[zip] => 77300
)
[role] => PHP Developer
)
php function to convert the object to array recursively
function objectToArray($d) {
if (is_object($d)) {
// Gets the properties of the object
$d = get_object_vars($d);
}
if (is_array($d)) {
return array_map(__FUNCTION__, $d);
}
else {
// Return array
return $d;
}
}
return array from object recursively
<?php
$employee_obj = new stdClass();
$employee_obj->name = 'Jamy Jo';
$employee_obj->age = 58;
$employee_obj->address->street = '240 Lake Rd';
$employee_obj->address->apartment = '240';
$employee_obj->address->state = 'Tx';
$employee_obj->address->city = 'Houston';
$employee_obj->address->zip = '77300';
$employee_obj->role = 'PHP Developer';
print_r(objectToArray($employee_obj));
function objectToArray($d) {
if (is_object($d)) {
// Gets the properties of the object
$d = get_object_vars($d);
}
if (is_array($d)) {
return array_map(__FUNCTION__, $d);
}
else {
// Return array
return $d;
}
}
?>

from array to object with simple array
<?php
$my_experience = array('work', 'life', 'happy');
$obj = (object) $my_experience;
print_r($obj);
?>
Display Result
stdClass Object
(
[0] => work
[1] => life
[2] => happy
)
complex array or multiple array to object
<?php
$my_experience = array(
'work', 'life', 'happy',
'happy2'=>array('go out','race car','programming'),
'programming'=>'php'
);
$obj = (object) $my_experience;
print_r($obj);
?>
display result
As you can see, multiple array is not converted to the object.
stdClass Object
(
[0] => work
[1] => life
[2] => happy
[happy2] => Array
(
[0] => go out
[1] => race car
[2] => programming
)
[programming] => php

$obj = arrayToObject($my_experience);
print_r($obj);
function arrayToObject($d) {
if (is_array($d)) {
//recurse function
return (object) array_map(__FUNCTION__, $d);
} else {

php class
<?php
class myinfo {
public $name;
public $age;
public $salary;
public function __construct($name, $age, $salary) {
$this->name = $name;
$this->age = $age;
$this->salary = $salary;
}
public function display() {
echo 'My name is ' . $this->name . '<br/>';
echo 'My age is ' . $this->age . '<br/>';
echo 'My salary is ' . $this->salary . '<br/>';
}
}
$mpersonal = new myinfo('Jammy', 24, 54000);
print_r($mpersonal);
?>
Display Result
myinfo Object
(
[name] => Jammy
[age] => 24
[salary] => 54000
)
convert the php class to array
<?php
class myinfo {
public $name;
public $age;
public $salary;
public function __construct($name, $age, $salary) {
$this->name = $name;
$this->age = $age;
$this->salary = $salary;
}
public function display() {
echo 'My name is ' . $this->name . '<br/>';
echo 'My age is ' . $this->age . '<br/>';
echo 'My salary is ' . $this->salary . '<br/>';
}
}
$mpersonal = new myinfo('Jammy', 24, 54000);
// convert class to array
$mypersonal_aa = (array)$mpersonal;
print_r($mypersonal_aa);
?>
Display Result
Array
(
[name] => Jammy
[age] => 24
[salary] => 54000
)
how to convert php array to class
<?php
class myclass {
public function __construct($array_class) {
foreach ($array_class as $key => $value) {
$this->{$key} = $value;
}
}
}
$array_class = array(
'Basic'=>'PHP',
'Advanced'=>'Object Oriented in PHP',
'Business'=>'Business System'
);
$computer_class = new myclass($array_class);
echo $computer_class->Basic; // display: PHP
echo $computer_class->Advanced; // display: Object Oriented in PHP
?>
a better method to convert array to class variable
<?php
class MyClass {
private $_myvariable;
public function __construct($properties) {
$this->_myvariable = $properties;
}
// magic methods!
public function __set($property, $value) {
return $this->_myvariable[$property] = $value;
}
public function __get($property) {
return
array_key_exists(
$property, $this->_myvariable) ? $this->_myvariable[$property] : null
;
}
}
$array_class = array(
'Basic'=>'PHP',
'Advanced'=>'Object Oriented in PHP',
'Business'=>'Business System');
$class1 = new MyClass($array_class);
echo $class1->Basic; // display: PHP
$class1->php_salary = 70000;
echo $class1->php_salary ; // display: 70000
?>
