所以你的问题应该是……

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.
