This is mainly determined by the stateless nature of the HTTP protocol.3. poor security and confidentiality. because most of the web objects are Internet users, security and confidentiality of information are an important issue on the internet. Although various technologies are trying to solve these problems, it is undeniable that security is always a relative concept. the inherent deficiency of HTTP brings a considerable security risk.To sum up, we should

Php frontend and backend separation technology when writing PHP programs, some code is used to process some transactions, such as database operations and mathematical operations, some other code is only the result of transaction processing, for example, some PHP code that uses echo statements to display results in HTML format on a Web browser and the HTML code that directly embeds the PHP program.

When writing a PHP program, some code is used to process some transactions, such as database operations and mathematical operations. Other code is only displayed as the result of transaction processing, for example, some PHP code that uses echo statements to display results in HTML format on a Web browser and the HTML code that directly embeds the PHP program. First, we should clearly distinguish the two types of code, the former is called the background program, and the latter is called the fro

Use GDB to debug programs and gdb to debug programs
GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compile
To use GDB for debugging, you must add the
