“包括"和“包括"之间的区别和“要求"在php中 [英] Difference between "include" and "require" in php

问题描述

它们之间有什么区别吗?使用它们是偏好问题吗?使用其中一种会产生任何优势吗?哪个更安全?

Is there any difference between them? Is using them a matter of preference? Does using one over the other produce any advantages? Which is better for security?

推荐答案

您可以在 the要求的页面:

You find the differences explained in the detailed PHP manual on the page of require:

require 等同于 include 除非失败，它还会产生致命的 E_COMPILE_ERROR 级错误.换句话说，它会停止脚本，而 include 只会发出一个警告 (E_WARNING) 允许脚本继续.

require is identical to include except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include only emits a warning (E_WARNING) which allows the script to continue.
