Absurd variable names in Javascript and PHP

absurd.js

// In javascript, object properties that are not valid for the dot syntax can be defined with square brackets. 
// Similar to PHP:
obj[' '] = 'foo';

// While there isn't a direct method to create a variable with a invalid name, 
// you can fake it using the document/window variable, or this
this[' '] = 'bar';

absurd.php

<?php

// In PHP, variables that are not valid like $var-name, can be defined as ${'var-name'}.
// Therefore:
${' '} = 'foo';

// Objects behave similarly:
$obj->{' '} = 'bar';

// Array keys don't have these issues, and behave like the ${} construct:
$array[' '] = 'baz';
