These days need to use PHP to write a timed crawl Web server application. Search the online solution, find several solutions, now summarized as follows.Scheduled operation of the task for a site, is a more important task, such as the timing of the release of documents, scheduled cleanup spam, and so on, most of the current Web site is the use of PHP dynamic language development, and the implementation of PHP has decided that it does not have the conce

Shutdown notifies init by message, and requires init to switch runlevel to achieve the above purpose.
If it is halt, switch to run
