substr() explode() function_PHP tutorial
substr(string,start,length): This function extracts length characters from the start position of the string string. If start is a negative number, it starts from the end of the string. If the omitted parameter length exists but is a negative number, it means that the length character from the bottom is obtained.
$str = "abc|bck|fhq|nui";
print(explode("|",$srt)); //Output array([0]=>abc,[1]=>bck,[2]=>fhq,[3]=> ;nui)
?>

Tips for dynamically creating new functions in golang functions
Apr 25, 2024 pm 02:39 PM
Go language provides two dynamic function creation technologies: closure and reflection. closures allow access to variables within the closure scope, and reflection can create new functions using the FuncOf function. These technologies are useful in customizing HTTP routers, implementing highly customizable systems, and building pluggable components.
Considerations for parameter order in C++ function naming
Apr 24, 2024 pm 04:21 PM
In C++ function naming, it is crucial to consider parameter order to improve readability, reduce errors, and facilitate refactoring. Common parameter order conventions include: action-object, object-action, semantic meaning, and standard library compliance. The optimal order depends on the purpose of the function, parameter types, potential confusion, and language conventions.

What are the benefits of C++ functions returning reference types?
Apr 20, 2024 pm 09:12 PM
The benefits of functions returning reference types in C++ include: Performance improvements: Passing by reference avoids object copying, thus saving memory and time. Direct modification: The caller can directly modify the returned reference object without reassigning it. Code simplicity: Passing by reference simplifies the code and requires no additional assignment operations.
What is the difference between custom PHP functions and predefined functions?
Apr 22, 2024 pm 02:21 PM
The difference between custom PHP functions and predefined functions is: Scope: Custom functions are limited to the scope of their definition, while predefined functions are accessible throughout the script. How to define: Custom functions are defined using the function keyword, while predefined functions are defined by the PHP kernel. Parameter passing: Custom functions receive parameters, while predefined functions may not require parameters. Extensibility: Custom functions can be created as needed, while predefined functions are built-in and cannot be modified.
C++ Function Exception Advanced: Customized Error Handling
May 01, 2024 pm 06:39 PM
Exception handling in C++ can be enhanced through custom exception classes that provide specific error messages, contextual information, and perform custom actions based on the error type. Define an exception class inherited from std::exception to provide specific error information. Use the throw keyword to throw a custom exception. Use dynamic_cast in a try-catch block to convert the caught exception to a custom exception type. In the actual case, the open_file function throws a FileNotFoundException exception. Catching and handling the exception can provide a more specific error message.
