PHP's Numeric & String Key Type Juggling

Arrays in PHP treat integer and string integers synonymously. If you set $a['1'] = '1' and access $a[1] you will get '1'. This is because php juggled your string key to an integer before assigning it; the assigment was actually made to an integer key. PHP also juggles in the process of accesssing too which means if you try to access [1] with ['1'] it will work. Therefore there is no real distinction between string integers and real integer, you can use them interchangably.

Remember that '1.0' does not equal '1' or 1 with strict comparison. This is true of array keys as well: you can have both ['1.0'] and ['1'] and they would be different elements but not [1] and ['1'].

PHP Testing if Two Variables are Referring to Same Data.

Adapted from this

PHP's strictest comparison operators still only go as far as indicating whether two variables have the same value but what if you want to be sure one variable is a reference to another, not just a container for a matching value?

PHP has no built in way to do this as of now but you can work around this by doing a test of your own. If you have this:

<?php
class Dynamic {
    public static $static_methods = array();
    // we can't have a $static_props because there is no __getStatic or __setStatic !!
    
    # $prop_defaults adds a property for all object (key) and provide a default value (value)
    # and is only in validating a new property on the object and not for storage.
    public static $prop_defaults = array();
    public $method = array();
