/* * include() require()。 * 这两种结构除了在如何处理失败之外完全一样。 * include() 产生一个警告而 require() 则导致一个致命错误。 * 换句话说，如果想在遇到丢失文件时停止处理页面就用 require()。 * include() 就不是这样，脚本会继续运行。 * * include_once() require_once() * 如果该文件中的代码已经被包含了，则不会再次包含。 * 错误处理方式和include() require() 相同。 */

We use the term function loosely, because require and include are not real functions but language constructs. 继续阅读 PHP各种读取文件的函数效率对比
