Object-oriented and process-oriented programming can only be used in many programming languages, but PHP is different from other programming languages, that is, we can freely choose orIf you are new to PHP, writing code in PHP's process-oriented style may be your only choice. However, if you often go to PHP forums and newsgroups, you should see articles about "objects. You may also see tutorials on How to Write object-oriented PHP code. Or you may have downloaded some ready-made class libraries

software similar to Nginx/lvs/haproxy, which is implemented at the software level, so it's very inexpensive.At present, the structure of the Web site architecture is generally more reasonable: the Web front-end uses nginx/haproxy+keepalived as the load balancer, and the backend uses the MySQL database as a master and read-write separation, using the lvs+keepalived architecture. Of course, according to the specific needs of the project plan.The following is the respective characteristics and app

1, Nginx advantages compared to Apache:Nginx lightweight, the same Web services, more than Apache occupy less memory resources;Anti-concurrency, Nginx processing request is asynchronous non-blocking type, Apache processing request is blocking type, so in dealing with high concurrency is nginx can keep low resource consumption and high performance;Highly modular design, relatively simple to write modulesHigh-performance modules produced quickly;The

implemented with LUA Apache is the most popular, why? Most people are lazy to update to nginx or learn new things # # ...12, for Nginx, I like it configuration file written very concise, regular configuration makes a lot of things easy to run high efficiency, less resources, powerful proxy, very suitable for the front-end response server# #看了一下, nginx configuration file is really more concise and easy to understand13. Apache in the processing of dynamic has

sample cardinality (up to 200), and some combine two sub models to handle both fast and slow updates. In fact, the selection of replaced samples to update the background model, in essence, is the sample life problem, the traditional way to use the first out of the replacement strategy. The probability of each sample being selected as a replacement sample is equal in the vibe background model, which is independent of the length of the sample's existence time, which guarantees that the sample lif

Brother even education in the long ago, answered a question about the back-end language selection, then what are the back-end language, what are the advantages and disadvantages? So brother even share with you a little bit of experience.Language Advantages and disadvantagesC + +C language is very close to the operating system of the language, and the operating sy

observedDisadvantages:1. The attributes we observe must be defined using strings. Therefore, the compiler will not appear warning and check;2. Refactoring the property will cause our observation code to be no longer available;3. Complex "IF" statements require that the object is observing multiple value http://www.pudncom.com/. This is because all the observation code is directed by a method;4. You do not need to remove the observer when releasing the Observer.Summarize:From the above analysis

many years, I once again met this ugly-looking colleague on the Internet and asked him how to win the game. His answer to my question is: the leaders get our conclusion and will almost only look at our "disadvantages". The advantages of most leaders will only take over or not at all. In fact, the advantages of many of my colleagues are complicated, and the

When multithreading technology is used and when to avoid it is an important topic we need to master. Multithreading is a double-edged sword. Its advantages and disadvantages must be fully considered during use.Multi-threaded processing can run multiple threads at the same time. Multi-threaded applicationsProgramDividing programs into multiple independent tasks can significantly improve performance in the fo
