How to Access Invalid Properties in PHP Objects with Complex Syntax?

Accessing Invalid Properties in PHP Objects

Manipulating an object's properties often involves using familiar dot syntax, such as $object->property. However, accessing properties with invalid names (e.g., containing periods, hyphens, or other reserved characters) poses a challenge.

Invalid Property Name

As mentioned in the provided context, PHP syntax prohibits accessing properties with invalid names using the traditional dot syntax. For example:

<?php
$insertArray = new stdClass();
$insertArray->First.Name = "John Doe"; // Invalid syntax
?>

Solving the Problem: Complex Property Syntax

To overcome this issue, PHP offers complex property syntax, primarily suitable for dynamic property access. The syntax utilizes curly braces around the invalid property name:

<?php
$insertArray = new stdClass();
$insertArray->{"First.Name"} = "John Doe"; // Valid syntax
?>

By enclosing the invalid property name in curly braces, you instruct PHP to treat it as a string, thus allowing you to access the property despite its unconventional characters.

Example

In the provided code snippet, the property name "First.Name" is considered invalid due to the period (.). To access this property, use the complex property syntax:

$insertArray[0]->{"First.Name"} = $firstname;

By adhering to the complex property syntax, you can successfully assign values to properties with invalid names, accommodating the requirements of the external API.
