Use the ereg function to determine user permissions_PHP tutorial
Save user permissions in the following format:
$perm=user,author,admin
If you want to add permissions, you can use
$perm.=,XXXX;
to add permission strings, with special characters in between Characters are separated. This example uses ","
When you need to determine whether the user has $isperm permissions in the program, you can use the following code:
$isperm=user;
if(ereg("$ isperm", "$perm")){echo "
is an ordinary user";
}else{
echo "
is not an ordinary user"; }
$isperm=author ;
if(ereg("$isperm", "$perm")){echo "
is a moderator";
}else{
echo "
is not a moderator"; }
$isperm=admin;
if(ereg("$isperm", "$perm")){echo "
is the administrator";
}else{
echo "
Not an administrator";}
It must be pointed out that the names of different permissions cannot be inclusive of each other, such as:
admin and bbsadmin
It is recommended that each permission name be added with a unique prefix or Suffixes, such as:
bbsadmin, chatadmin, webadmin
are OK.

It allows users to perform more in-depth operations and customization of the system. Root permission is an administrator permission in the Android system. Obtaining root privileges usually requires a series of tedious steps, which may not be very friendly to ordinary users, however. By enabling root permissions with one click, this article will introduce a simple and effective method to help users easily obtain system permissions. Understand the importance and risks of root permissions and have greater freedom. Root permissions allow users to fully control the mobile phone system. Strengthen security controls, customize themes, and users can delete pre-installed applications. For example, accidentally deleting system files causing system crashes, excessive use of root privileges, and inadvertent installation of malware are also risky, however. Before using root privileges

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.

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.

The key to writing efficient and maintainable Java functions is: keep it simple. Use meaningful naming. Handle special situations. Use appropriate visibility.

1. The SUM function is used to sum the numbers in a column or a group of cells, for example: =SUM(A1:J10). 2. The AVERAGE function is used to calculate the average of the numbers in a column or a group of cells, for example: =AVERAGE(A1:A10). 3. COUNT function, used to count the number of numbers or text in a column or a group of cells, for example: =COUNT(A1:A10) 4. IF function, used to make logical judgments based on specified conditions and return the corresponding result.

The advantages of default parameters in C++ functions include simplifying calls, enhancing readability, and avoiding errors. The disadvantages are limited flexibility and naming restrictions. Advantages of variadic parameters include unlimited flexibility and dynamic binding. Disadvantages include greater complexity, implicit type conversions, and difficulty in debugging.

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.

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.
