php – require,include,require_once和include_once之间的区别?

作者:互联网

PHP中:

>我什么时候应该使用require vs. include?
>我什么时候应该使用require_once vs. include_once?

解决方法:

还有require和include_once.

所以你的问题应该是……

>我什么时候应该使用require vs. include?
>我什么时候应该使用require_once vs. require

对于1的答案描述为here.

The require() function is identical to include(), except that it handles errors differently. If an error occurs, the include() function generates a warning, but the script will continue execution. The require() generates a fatal error, and the script will stop.

2的答案可以在here找到.

The require_once() statement is identical to require() except PHP will check if the file has already been included, and if so, not include (require) it again.
