Of course, there may be multiple root classes to implement different functions. in a well-designed system, each root class should have a useful interface that can be used by application code. if our application code is designed to work with the root

JSP uses JDBC for dynamic verification and MVC for data query. jdbcmvc This example describes how to use JDBC to perform dynamic verification and use MVC to query data. Share it with you for your reference. The details are as follows: I. Objectives:

Process ControlLet's turn to the process control and condition marking of JSTL. If you have used conditions and flow control statements in any language, theoretically there is nothing new here.C: test the if action processing Simple Condition

How to do the following {code ...}: $ Data = [, 3, [a, B, c]; the number in the foreach ($ data as & $ e) {// $ data array is unknown, one-dimensional arrays Add 1 and two-dimensional arrays splice m} var_dump ($ data); // [2, 3, 4, [am, bm, cm]

The object-oriented program is built through the hierarchical structure of classes. In a single re-inheritance language such as PHP, class inheritance is tree-like. A root class has one or more sub-classes, and then inherits one or more sub-classes

The control structure of php is mostly the same as that of other mainstream languages, such as C and Java.Here are some different and frequently-tested details:1> alternative Syntax of process control (pascal style)It is mainly used in if, while,

PHP two-dimensional array deduplication UDF. If we use one-dimensional data to repeat items, we should not say that there are direct functions, but php does not provide functions for two-dimensional data, the following small series will recommend
