How Can I Access PHP Object Properties with Illegal Names Like 'todo-items'?

Accessing Properties with Illegal Names in PHP

Within PHP, accessing object properties with illegal names, such as those containing hyphens (-), can be challenging. Consider the following scenario:

Problem:

You have retrieved an object from an API call, and despite its var_dump revealing the presence of a "todo-items" property, you are unable to access it directly using $object->todo-items.

Solution:

There are several methods to access such properties:

1. Property Name Encapsulation:

   PHP allows you to encapsulate property names in curly braces to access them directly. This works even for illegal names:

   $object->{'todo-items'}

2. Variable Assignment:

   Assign the property name to a variable and access it using the variable within square brackets:

   $todolist = 'todo-items';
   $object->$todolist

3. Array Conversion:

   Convert the object to an array using a technique like the one employed by Zend_Config:

   public function toArray()
   {
       $array = array();
       foreach ($this->_data as $key => $value) {
           if ($value instanceof StdClass) {
               $array[$key] = $value->toArray();
           } else {
               $array[$key] = $value;
           }
       }
       return $array;
   }
