    An object is an instance of a class. It is simply a specimen of a class and has memory allocated. Array is the data structure that stores one or more similar type of values in a single name but associative array is different from a simple PHP array. An array which contains string index is called associative array. It stores element values in association with key values rather than in linear index order.
    Method 1: Using json_decode and json_encode method: The json_decode function accepts JSON encoded string and converts it into a PHP variable on the other hand json_encode returns a JSON encoded string for a given value.
    Syntax: 
     

    $myArray = json_decode(json_encode($object), true);

    Example: 
     

    php

    <?php

    class sample {

        var $var1;

        var $var2;

        function __construct( $par1, $par2

        {

            $this->var1 = $par1;

            $this->var2 = $par2;

        }

    }

    $myObj = new sample(1000, "second");

    echo "Before conversion: \n";

    var_dump($myObj);

    $myArray = json_decode(json_encode($myObj), true);

    echo "After conversion: \n";

    var_dump($myArray);

    ?>

    Output:

    Before conversion: 
    object(sample)#1 (2) {
      ["var1"]=>
      int(1000)
      ["var2"]=>
      string(6) "second"
    }
    After conversion: 
    array(2) {
      ["var1"]=>
      int(1000)
      ["var2"]=>
      string(6) "second"
    }

    Method 2: Type Casting object to an array: Typecasting is the way to utilize one data type variable into the different data type and it is simply the explicit conversion of a data type. It can convert a PHP object to an array by using typecasting rules supported in PHP.
    Syntax: 
     

    $myArray = (array) $myObj;

    Example: 
     

    php

    <?php

    class bag {

        var $item1;

        var $item2;

        var $item3;

        function __construct( $par1, $par2, $par3

        {

            $this->item1 = $par1;

            $this->item2 = $par2;

            $this->item3 = $par3;

        }

    }

    $myBag = new bag("Mobile", "Charger", "Cable");

    echo "Before conversion : \n";

    var_dump($myBag);

    $myBagArray = (array)$myBag;

    echo "After conversion : \n";

    var_dump($myBagArray);

    ?>

    Output:

    Before conversion : 
    object(bag)#1 (3) {
      ["item1"]=>
      string(6) "Mobile"
      ["item2"]=>
      string(7) "Charger"
      ["item3"]=>
      string(5) "Cable"
    }
    After conversion : 
    array(3) {
      ["item1"]=>
      string(6) "Mobile"
      ["item2"]=>
      string(7) "Charger"
      ["item3"]=>
      string(5) "Cable"
    }
