php array is converted into Object methods

Method 1: Forced type conversion----Add the target type enclosed in parentheses before the variable to be converted

The PHP data types that are allowed to be converted are:

• (int), (integer): converted to integer

• (float), ( double), (real): Convert to floating point type

• (string): Convert to string

• (bool), (boolean ): Convert to Boolean type

• (array): Convert to array

• (object): Convert to object

Example: Convert array to object type

<?php
$arr=[&#39;a&#39;=>10,&#39;b&#39;=>100,&#39;c&#39;=>&#39;Hello&#39;];
$obj=(Object)$arr;
var_dump($arr); 
var_dump($obj); 
?>

Output:

Method 2: Use json_encode() and json_decode () Function

<?php
header(&#39;content-type:text/html;charset=utf-8&#39;);
$arr=[&#39;a&#39;=>10,&#39;b&#39;=>100,&#39;c&#39;=>&#39;Hello&#39;];
$arr0 = json_encode($arr);
$arr1 = json_decode($arr0,true);
$arr2 = json_decode($arr0);
var_dump($arr); 
var_dump($arr0); 
var_dump($arr1); 
var_dump($arr2); 
?>
