We use the database configuration in the Laravel or CI framework and then take the data out of each controller. This is not with each native PHP single page write a mysql_contact, that is, each page to connect to the database once. The essence is different, that is, the PHP framework can be configured for us to configure a persistent data connection, reduce the database duplicate connection cost per page? Some people say that the frame is also connected to each page once, and does not reduce the

Connect to the network driveDo not use a directed drive for scheduled jobs that need to access the network. The scheduler service may not be able to access these redirected drives, or the redirected drives may not appear if other users log on when the scheduled task is running. Therefore, use the UNC path for scheduled jobs. For example:

First, obtain the parameters of the namespace method through arguments, divide them into arrays by dots, and recursively assign values to empty objects. The namespace built in the system is used.
The Code shows that if the input string parameter is separated by ".", multiple objects will be created, for example:Ext. namespace ('System. Corp ');
Two objects will be created, which is equivalent to executing the following code:System = {};
