Tipagem dinâmica significa que os tipos das variáveis são associadas à valores, e não à variáveis. Ou seja, o tipo de uma variável é inferido em tempo de execução, o que permite que ela seja variada no decorrer do código.

<?php
$foo = 'bar'; // tipo `string`
$foo = 123;   // agora é do tipo `integer`
$foo = 1.3; // agore é do tipo `double`
