PHP Object to Array Conversion [With Example]

When it comes to building websites, PHP is among the most extensively used general-purpose scripting languages. It is a highly efficient and adaptable language for computer programming. Processing data types is the crux of working with PHP. Even though PHP has several different data types, objects and arrays are its composite data types. The focus of this essay is on using PHP to transform an object into an array.

Object-Oriented Programming (OOP) in PHP

PHP's object-oriented programming model, in which data is conceptualized as an object upon which functionality is built, is a major feature. One of the sophisticated PHP techniques that simplify the process is this. PHP allows for object-oriented programming, wherein objects execute according to the guidelines set forth by the PHP program. Classes are the name given to these types of regulations. If you need to change an object into an array in PHP, they are crucial.

Some OOP Concepts

First, we'll get familiar with some crucial PHP Object-Oriented Programming terminology before diving into the specifics of object conversion to arrays.

Class

Data types a programmer defines are referred to as "classes." There is a focus on localization, therefore it also takes into account local function and data. It is possible to create objects of the same type using the same class as a template.

Object

A data structure's instances are defined by classes. After declaring a class once, multiple instances of the class's objects can be created. When referring to an object, the term "instance" is also commonly used.

Example Defining a Class and its Objects

class Jobs {

   // Members of class Jobs

}

// Creating three objects of Jobs

$marketing = new Jobs;

$consulting = new Jobs;

$HR = new Jobs;

Array

When working with PHP, it is common to use arrays, which are a specific type of variable that can store many values.

Defining an Array

In PHP, the array is defined with the array function ‘array()’.

Example:

<?php

$letters = array(“a”, “b”, “c”);

echo count($letters);

?>

Object to Array PHP

In PHP, there are two major ways to transform an object into an array:

● Typecasting object to array PHP

● Implementing JSON Decode and Encode method

Example #1

PHP program to convert an object to an array using the typecasting method.

Code:

<?php

class hospital

{

var $n1;

var $n2;

var $n3;

function __construct( $dis1, $dis2, $dis3)

{

$this->item1 = $dis1;

$this->item2 = $dis2;

$this->item3 = $dis3;

}

}

// Creation of object for the class

$dis = new hospital("D", "S", "C") ;

echo "Items before conversion : " ;

var_dump($dis);

// convert object to array

$arr = (array)$dis;

echo "Items after conversion : ";

var_dump($arr);

?>

Explanation: In this code, we first construct an instance of the hospital class and then insert three subclasses, namely n1, n2, and n3 into it. An object's creation triggers the execution of the subsequently declared __construct() function. After this is done, the "new" keyword can be used to create an object, at which point the constructor can accept any number of arguments. As can be seen in the code, the first instance of the expression var dump causes the printing of objects (). However, in the second expression case, typecasting is used to convert an object into an array.

Example #2

PHP program to convert an object to an array using json encode and json decode.

Code:

<?php

class hospital

{

var $n1;

var $n2;

function __construct( $dis1, $dis2 )

{

$this->item01 = $dis01;

$this->item02 = $dis02;

}

}

// Creating object

$dis = new hospital(500, "C");

echo "Items before conversion: " ;

var_dump($dis);

// convert object to array

$arr = json_decode(json_encode($dis), true);

echo "Items after conversion: ";

var_dump($arr);

?>

Explanation: Again, the program begins by defining a class called "hospital," and then two components, n1 and n2 are added to the class. An object's creation triggers the execution of the subsequently declared __construct() function. Once this is accomplished, the constructor can accept the optional arguments sent in when creating an object with the new keyword. The first instance of the expression var_dump in the code prints an object (). In contrast, the second expression type uses the typecasting process to convert an object into an array. The object is converted into an array using the first method listed under the method sections.
