Automagic

Automagic is a porte-manteau, merging automatic and magic. Some PHP operations are automagic, meaning that a lot more is process that what it appears.

Such operations are usually yielding surprise and confusion, or are a cherished feature.

Automagic is mostly used as an adverd, automagically.

<?php

var_dump(10 === '1e1');  // true
// PHP automagically converts the string into a number, and 1e1 yields 10.

$array = [null => 1, '33' => 2];
echo $array[0]; // 1
// PHP converts the NULL into 0
echo $array[33]; // 2
// PHP converts numeric strings to strings

?>
