Copy Code code as follows:
A helper is a PHP function defined by Symfony in a template. He outputs HTML code and is much faster than the actual HTML code we write ourselves. Using the Symfony helper, the output we get with the following code is the same as the usual HTML code above:

Transactional: atomicity, consistency, separation, persistenceA thing (transaction) is an execution unit that consists of a sequence of column operations, which are either done or not, and are an inseparable unit of work.Four basic properties of a Database Thing (ACID)1. atomicity (atomicity)It means that all the actions contained in the thing are either done entirely or not (all or none).For example, a bank withdrawal transaction is divided into 2 steps (1)
, clear all objects in the memory block in use, swap the two memory roles, and complete the garbage collection.
If there are many garbage objects in the system, the number of surviving objects that the replication algorithm needs to replicate is not too large. As a result, the efficiency of the replication algorithm is high at a time when garbage collection is really needed. And because objects are uniformly copied to the new memory space during garbage collection, you can ensure that the reclai
The four characteristics of database transactions ( acid) are:(1) atomicity (atomicity) The atomicity of a transaction is that the program contained in the transaction acts as a logical unit of work for the database, which either executes all of the data modification operations or does not execute at all. This characteristic is called atomicity.For example, a bank withdrawal transaction is divided into 2 steps (1) passbook reduction (2) to withdraw c
