示例1: raise
/**
* Sets the PHP time limit to a number of seconds from now.
*
* This function will always extend the time limit (in other words, if the time
* limit has already been set further in the future, it will do nothing).
*
* In order to support front-end servers which may time out silently if no
* output is displayed, you should ideally only call this function if you expect
* some output to be displayed at the same time. (I.e. if you call this function
* each time around a loop, also display some output each time around the loop,
* such as a progress bar update.)
*
* @param int $newlimit Limit in seconds from now (0 = infinite)
