offset : 留空 - 查找第一个出现的位置
int - 由该位置搜索出现的第一个位置
"r" - 查找最后一次出现的位置 (strrpos)
"a" - 将所有查找到的字储存为数组(返回 array)
string GB_replace(needle,str,haystack) -- 查找与取代字符串 (str_replace)
string GB_replace_i(needle,str_f,str_b,haystack) -- 不检查大小写查找与取代字符串
needle - 查找字母
str - 取代字母 ( str_f - 该字母前, str_b 该字母后)
haystack - 字符串
string GBsubstr(string,start,[length]) -- 从string提取出由开始到结尾或长度
length的字符串。
中文字只计一字母,可使用正负数。
string GBstrnear(string,length) -- 从 string提取最接近 length的字符串。
length 中 中文字计2个字母。
--- 注意 ---
如使用由 Form 返回的字符串前,请先替字符串经过 stripslashes() 处理,除去多余的 。
用法:在原 PHP 代码内加上:
include ("GB.inc");
即可使用以上工具函数。

Using the chrono library in C can allow you to control time and time intervals more accurately. Let's explore the charm of this library. C's chrono library is part of the standard library, which provides a modern way to deal with time and time intervals. For programmers who have suffered from time.h and ctime, chrono is undoubtedly a boon. It not only improves the readability and maintainability of the code, but also provides higher accuracy and flexibility. Let's start with the basics. The chrono library mainly includes the following key components: std::chrono::system_clock: represents the system clock, used to obtain the current time. std::chron

Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.

C code optimization can be achieved through the following strategies: 1. Manually manage memory for optimization use; 2. Write code that complies with compiler optimization rules; 3. Select appropriate algorithms and data structures; 4. Use inline functions to reduce call overhead; 5. Apply template metaprogramming to optimize at compile time; 6. Avoid unnecessary copying, use moving semantics and reference parameters; 7. Use const correctly to help compiler optimization; 8. Select appropriate data structures, such as std::vector.

The main steps and precautions for using string streams in C are as follows: 1. Create an output string stream and convert data, such as converting integers into strings. 2. Apply to serialization of complex data structures, such as converting vector into strings. 3. Pay attention to performance issues and avoid frequent use of string streams when processing large amounts of data. You can consider using the append method of std::string. 4. Pay attention to memory management and avoid frequent creation and destruction of string stream objects. You can reuse or use std::stringstream.

The application of static analysis in C mainly includes discovering memory management problems, checking code logic errors, and improving code security. 1) Static analysis can identify problems such as memory leaks, double releases, and uninitialized pointers. 2) It can detect unused variables, dead code and logical contradictions. 3) Static analysis tools such as Coverity can detect buffer overflow, integer overflow and unsafe API calls to improve code security.

To implement loose coupling design in C, you can use the following methods: 1. Use interfaces, such as defining the Logger interface and implementing FileLogger and ConsoleLogger; 2. Dependency injection, such as the DataAccess class receives Database pointers through the constructor; 3. Observer mode, such as the Subject class notifies ConcreteObserver and AnotherObserver. Through these technologies, dependencies between modules can be reduced and code maintainability and flexibility can be improved.

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.

C performs well in real-time operating system (RTOS) programming, providing efficient execution efficiency and precise time management. 1) C Meet the needs of RTOS through direct operation of hardware resources and efficient memory management. 2) Using object-oriented features, C can design a flexible task scheduling system. 3) C supports efficient interrupt processing, but dynamic memory allocation and exception processing must be avoided to ensure real-time. 4) Template programming and inline functions help in performance optimization. 5) In practical applications, C can be used to implement an efficient logging system.
