    A classe Thread

    (PECL pthreads >= 2.0.0)

    Introdução

    Quando o método start de um Thread é invocado, o código do método run será executado em Thread separado, em paralelo.

    Após a execução do método run, o Thread será encerrado imediatamente e será unido ao Thread de criação no momento apropriado.

    Aviso

    Depender do mecanismo para determinar quando um Thread deve ingressar pode causar um comportamento indesejável; o programador deve ser explícito, sempre que possível.
