PHP programming development How to improve the efficiency of programming PHP programming technology, programming development programming technology
Using single quotes instead of double quotation marks to contain strings can be faster. Because PHP will search for variables in a string surrounded by double quotes, single quotes will not, note: only echo can do this, it is a string can be used as a parameter
Simple implementation of PHP encryption technology and php encryption technology
1. MD5 Encryption
Take a logon page as an example:
I remember that MD5 is also used for comparison, so the password is saved when there is a database.

Fault symptom:Intel has stopped marketing and development for Intel wireless display technology and Intel PRO wireless display technology (Intel Pro WiDi) wireless display applications, as well as certification programs for related receivers, and takes effect immediately.Because Windows 10 and Windows 8.1 * support the Miracast * standard for wireless display and provide excellent user experience, Intel wil
developersApp developers if they want to monetize the app, the product manager has to look at the user's point of view when developing the app, think about what the user really wants, what the app does for them, and how easy it is for them to use the app software. App developers should return to the origin in the process of production, from the marketing 4P in the top three p: products, prices, channels, to explore the core competitiveness.Third, the user experience is the focus of app mobile c
In the previous blog post, I mainly described how to get and set the system's default printer, this article will describe how to monitor the status of the printer in real-time, recording the printed documents, the number of copies printed, as well as the printing time and other printing information.1. Printer Collapse Machine TechnologyBefore we formally introduce how to monitor the state of the printer in real time, we need to know about the printer collapse machine
Improvement of front-end programming (18th) ---- research on popular mobile web interaction technology solutions and web technology solutions
After my internship stops, the biggest change in my life is that there is no project pressure. You can explore technical implementation based on your interests. For individuals, this process is self-motivated and requires top-down control.

Speech Recognition ( SR Technology (or "voice technology") has become the biggest "hot spot" (or "focus point") of today's science and technology research has objective reasons. Why? In the domestic research, often like "trend", do not ask what objective conditions, like "reckless." We do things to understand the surrounding environment, to see the situation agai
Search market, expand the territory of the people, competition between each other to rise to "white-hot." This is because search has become the second largest application of the Internet, and is called "the cornerstone of E-commerce", "the strategic core of the Internet", and Google's fame and fortune demonstration effect, but also exacerbated the fanatical chase.

Quantum computing has always been confusing. You need to read a lot of technical materials to understand this technology. However, quantum technology may become a reality within ten years, which will have a huge impact on the industry.
Currently, most encryption algorithms (especially public and private keys) are feasible because their mathematics makes it difficult for conventional (non-quantum) computers

optical fiber channels, the reasonable cost is about 1 Gigabit or two thousand MB, which costs about 50 thousand to 60 thousand USD. From another perspective, although the new iSCSI-based SAN solution only costs about $20 thousand to $30 thousand, its performance cannot be compared with that of the fiber channel. The major difference in prices is that iSCSI technology uses a large number of production of gibit Ethernet hardware, while fiber channel
