During development, we often use three design modes to help us solve the scalability of project code. In simple factory, factory method, abstract factory, the code is actually very simple, mainly to understand and use. Simple Factory: To put it bluntly, the switch is used for instantiation Based on the passed parameters. Factory method: The factory method is used to upgrade a simple factory with swicth added each time. Provide a factory class for each product. Abstract Factory: Abstract Factor

1. When you travel for a long distance in the rainy road at night, there is no rain in front of you. At this time, you may speed up your speed and think that there is no rain in front of you, the road surface should be dry. This is a bad judgment. Because the rain just stopped in front of the road will accumulate water on the road. If you speed up at this time, and the sight is not good at night, it will often cause the water on the ground to splash on your windshield, it will be very dangerous,

Windows kernel objects: The Windows kernel can process any event in an orderly manner, and how to arrange and run the internal mechanism (including the event mechanism, mutex lock mechanism, semaphore mechanism, and wait mechanism ). An example of "parking space in a car farm, parking space in a car" is used to explain the meaning of Windows kernel objects, 1. EventN (infinite) Car N (infinite) parking space. For manual event resetting, it is like a parking lot with infinite parking spaces. Whe

wheel is locked mechanically to prevent slipping. In addition, the automatic variable speed car is equipped with a gap to start the switch, so that the car can only start the engine in the "P" or "N, in this way, the car suddenly exists when it is mistakenly started in other gear positions. R (reverse) reverse: R is used for reversing. Unlike manual transmission cars, automatic transmission cars can use se

If you want to run the same code over and over again, and the values are different each time, it is convenient to use loops.document.write (Cars[0] + ");d ocument.write (cars[1] + ");d Ocument.write (cars[ 2] + ");d ocument.write (cars[3] + ");d ocument.write (cars[4] + ");d

If you want to run the same code over and over again and the values are different each time, it's convenient to use loops. Copy Code code as follows: document.write (Cars[0] + "document.write (Cars[1] + "document.write (cars[2] + "document.write (Cars[3] + "document.write (

The main purpose of this article is to explain the mixed use of JavaScript arrays and objects, because of the weak check characteristics of JS, so in the JS array can store different types of variables, such as you can put numbers, strings, characters, objects and other content in the same array. objects can do the same thing, except that an object can specify an alias for each member of the object, so that the data is easier to read when programming, such as: var arr1 = ["Flying Fish",

PHP-sorting functions for arraysIn this section, we will learn the following PHP array sorting functions:Sort ()-sorts an array in ascending orderRsort ()-sorts the array in descending orderAsort ()-sorts associative arrays in ascending order based on valuesKsort ()-Sorts the associative array in ascending order, based on the keyArsort ()-sorts associative arrays in descending order by valueKrsort ()-Sorts the associative array in descending order, based on the keySorting an array in ascending o

To achieve online war, you must have the support of the backend server. This article is based on a simple example To explore how to use Flash and the Java servlet combination to achieve the network between the station. It should be noted that this article readers need to have some knowledge of Flash and Java servlet progra

access global variables within functions. (To do this, use the Global keyword before (inside the function) variable)9.PHP Static KeywordsTypically, all variables are deleted when the function finishes/executes. However, sometimes I need to not delete a local variable. Achieving this requires a bit of further work.To do this, use the static keyword when you first declare the variable.10.PHP Echo and Print statementsThe difference between Echo and print:echo-capable of outputting more than one st

First go to the demo code (phalcon framework): {code ...} by listening to the underlying SQL generation of phalcon, the sample code above will be parsed into two SQL statements: {code ...} that is to say, when executing the update statement at the underlying layer of PHQL, the related records are first queried based on the conditions, and then based on the related records... first go to the demo code (phalcon framework ): $phql = "UPDATE Cars SET p
