Why Do Common Methods Fail to Convert stdClass to Array in PHP?

PHP stdClass to Array Conversion

When attempting to convert a stdClass object into an array in PHP, various approaches might not yield the desired results. This article explores why some common methods fail and offers an alternative solution that preserves the object's data.

Ineffective Methods

The following methods may result in an empty array due to incorrect usage or limitations:

• Casting the object with (array)
• Using json_decode($booking) without specifying an associative array option
• Implementing a recursive objectToArray() function

The Lazy One-Liner Method

To efficiently convert a stdClass object to an array, we can utilize the JSON encoding and decoding methods in PHP. Here's the one-liner solution:

$array = json_decode(json_encode($booking), true);<br>

This approach avoids the performance overhead of iterating through the object recursively while preserving all the object's data.

Requirements

The json_encode and json_decode methods are built-in functions in PHP versions 5.2.0 and above. If using an older PHP version, the PECL library is required.

$stdClass = json_decode(json_encode($booking));<br>

Converting stdClass to Array

The json_decode method allows us to specify an "assoc" argument, which indicates whether to convert objects into associative arrays. By setting this value to true, we can convert the stdClass object into an array:

$array = json_decode(json_encode($booking), true);<br>

This solution offers a convenient and efficient way to handle stdClass to array conversions in PHP.
