can be written to each page when the workload is low, but imagine how much effort you will spend when there are more than 100 pages and you need to change all of their headers or bottoms? How tedious and boring is manual changes on one page! Therefore, we should write PHP headers and bottom files for these pages, and then we just need to reference them in each HTML page. The include and require functions contain a PHP code file. regardless of the file extension, the file is treated as a PHP fil

database governance. If you have a website for selling books, you may have a list of authors, a list of book prices, and a list of current inventory and orders. As your business continues to increase, orders will continue to increase, and a lot of disk visits are required to process each order. It is very likely that you will put all the orders in an accounting system one day. Now, place the order in an independent database. Because the inventory is updated through the order, the inventory is a

This article describes the risks and solutions of using the. inc file in php. one of the main issues that need to be paid attention to when using the database is access permissions, that is, exposure of user names and passwords. For convenience in programming, a db. inc file is usually used for storage, such: The code is as follows: $ Db_user = 'myuser ';$ Db_pass = 'mypass ';$ Db_host = '2017. 0.0.1 ';

This article mainly introduces the static variable of PHP introduction, has a certain reference value, now share to everyone, the need for friends can refer to 1 static variables within a functionOnly works inside the function, and after each call, the value of the static variable is changed on the basis of the last call. When defined, if the initial value is given, then the statement executes only onceFor example: No matter how many times the GetData () function is called static $c 2 = 0; This

Using the monotone queue to find the maximum minimum value of row J of line I to row j+n-1 of line I, and then use this to find the maximum minimum value of row J of line I to column i+n-1 j+n-1.
