This article mainly introduces the example of PHP that does not require Recursion to implement unlimited classification. It is actually a way of thinking and explained with a simple example, for more information, see the following two tree array operators that do not require recursion.
The Code is as follows:

If you need to wake up all the threads waiting for a condition variable, you need to call:Pthread_cond_broadcast (pthread_cond_t * cptr);By default, blocked threads wait until they know that a condition variable is true. If you want to set the maximum blocking time, you can call:Pthread_cond_timedwait (pthread_cond_t * cptr, pthread_mutex_t *mptr, const struct TIMESPEC *abstime);If the time is up, the condition variable is still not true, and the return value is etime. 6.

MySql unlimited classification structureUnlimited classification is a very common application in our development, such as forum sections, CMS categories, and many applications.The most common and simple method is ID, parentID, and name in MySql. The advantage is simple and the structure is simple.The disadvantage is that the efficiency is not high, because the database needs to be queried every recursion, and hundreds of databases are not very fast!
