Self is bound to a because it's defined in a ' s implementation of The first method, whereas static is bound to the called Class (also see Get_called_class ()).classA { Public
0x00 backgroundFor PHP code audit needs, we certainly need a good PHP code Audit analysis Tool--rips, which uses static analysis technology, can automatically mining PHP source code potential security vulnerabilities such as XSS, SQL injection, sensitive information disclosure, file inclusion and other common vulnerabilities ; You can also scan your code to disco
It is very important to know some knowledge about static routing configuration commands. So I have studied the detailed analysis of the configuration commands. Here, I will share with you. I hope this will be helpful for your reference.
Configure or delete static route configurations
[No] ip route ip-address{Mask | mask-length} {interfacce-name| Gateway-address}
differs from static methods is that static methods are loaded into memory when the script is interpreted, and the singleton is loaded into memory only when new is available (provided the code for both is loaded into the memory code area)
Auto Load:
There is an explanation of the automatic loading in front (AutoLoad implementation Mechanism in PHP)
When we

PHP generates static page analysis templates, caches, and writes files. I. INTRODUCTION in terms of speed, static pages are much faster than dynamic pages, such as php. this is without a doubt, but due to the poor flexibility of static pages, if you do not use the database or other settings

Recent games into the tail, has been on-line operation, the demand is relatively small, can have time to organize the optimization of the code, but the optimization without a standard, it is difficult to have a practical effect, so first from the simple code
The examples in this article describe the use of static variables in C # classes. Share to everyone for your reference. The specific analysis is as follows:Take a look at the code first: The code is as follows:Using System; Namespace Param { Class Class1 { static int i = Getnum (); Int J = Getnum (); static int num = 1
/ifup-post, which has a line:/etc/sysconfig/network-scripts/ifup-routes ${realdevice} ${devname}-Finally Analysis/etc/sysconfig/network-scripts/ifup-routes, this script is used to start the static route script, there are two functions: Handle_file () and Handle_ip_file (), are used to add routes, but they do not have the same file format, that is, static route fi
or abstract classes, the factory class needs to decide when to create the kind of product, which is confused with the products that create the kind of product, violating a single duty, resulting in loss of flexibility and maintainability of the system. And more importantly, the simple factory model violates the "open closure principle", which violates the "system open to expansion, to modify the" principle, because when I add a new product must modify the factory class, the corresponding factor
Generating static pages is a good choice for php to reduce server load and seo website optimization. Therefore, the php static page generation function is a knowledge point that almost all php programmers must understand and master, next, I will introduce you to the Analysis of the Principle of generating static pages
: Returns the import struct, containing the introduced class name, the package name
Parsingproperty.swift: Parses the defined attribute property information
Parsinginterface.swift: According to this analysis of the number of categories defined in a file, the structure of the class Object class name, the parent class name, the class name will be resolved here.
Parsingprotocol.swift: The parsed protocol is set to the Object structure body.
/* * * static and extern modifiers local and global variables //Static can modify local variables //Effects: 1) The scope of the variable defined by static will be extended //2) The statement of the variable defined by static will only be executed once extern is not able to decorate the
reference case analysis). For the function name of the dynamic array, the result is 4 whenever the sizeof operation is performed.
Third,New also need you delete, is in the heap allocation space, the efficiency is low, and [] directly on the stack allocation, will automatically release, high efficiency, but the stack space is limited .

Generating HTML principle Analysis
We write the label to be generated as a template file, and then use PHP read to replace the specified label with the content we want to replace it, now the mainstream of the DEDECMS system is also doing so
Generate static page code.
The template is not yet populated with the content HTML file. For example:
The code is as follows

Suppose you have a class like this:public class Utils { Static { LOG.I ("Static", "isload!"); }Public static void Staticcode () {}public int value;public void Nostaticcode () {}}When will the static code block be loaded when the whole program is running?1. When instantiating the class. Column: New Util
Before formally entering the test, it is helpful to do some static code analysis and code review to improve the quality and the system, the above is the data proofPMD It is a Java source code parser based on a static rule set that identifies potential problems such as:– Possible bug--empty try/catch/finally/switch blocks.– Useless codes (Dead code): Useless local
