The difference between Local Value (local variable) and Master Value (main variable) in phpinfo()_php skills
Many parts of phpinfo() have two Column: Local Value and Master Value
1. Master Value is the content in the PHP.ini file.
2.Local value is the setting in the current directory. This value will overwrite the corresponding value in Master Value
Due to the settings of WEB Sever Config or .htaccess, or the settings of ini_set() in the program, the settings in the current directory will be different from the settings in the PHP.ini file
PS: The settings of php.ini can be overridden in the Apache configuration file, which may be in conf/httpd.conf or conf.d/***.conf, usually in conf.d/php.conf Medium

What is the difference between local variables and global variables of a C++ function?
Apr 19, 2024 pm 03:42 PM
The difference between C++ local variables and global variables: Visibility: Local variables are limited to the defining function, while global variables are visible throughout the program. Memory allocation: local variables are allocated on the stack, while global variables are allocated in the global data area. Scope: Local variables are within a function, while global variables are throughout the program. Initialization: Local variables are initialized when a function is called, while global variables are initialized when the program starts. Recreation: Local variables are recreated on every function call, while global variables are created only when the program starts.
C++ syntax error: When a function returns a pointer or reference, it cannot return a local variable or temporary object. What should I do?
Aug 22, 2023 am 09:22 AM
C++ is an object-oriented programming language, and its flexibility and power often provide programmers with great help. However, precisely because of its flexibility, it is difficult to avoid various small errors when programming. One of the most common mistakes is that when a function returns a pointer or reference, it cannot return a local variable or temporary object. So how to deal with this problem? This article will introduce the relevant content in detail. The cause of the problem is that in the C++ language, local variables and temporary objects are dynamically allocated during the running of the function. When the function ends, these local variables and temporary
Data competition analysis of global variables and local variables of Golang functions
May 21, 2023 am 08:19 AM
Golang is a strongly typed programming language with features such as efficiency, simplicity, and concurrency, so it is gradually favored by more and more developers. In the development of Golang, the global variables and local variables of functions often involve data competition issues. This article will analyze the data competition problem of global variables and local variables in Golang functions from the perspective of actual coding. 1. Data competition for global variables Golang global variables can be accessed in all functions, so if rigorous design and coding are not carried out
Local variable type inference in Java 10: How to simplify your code using var keyword
Jul 29, 2023 pm 07:32 PM
Local variable type inference in Java10: How to use the var keyword to simplify code Introduction: In Java10, the feature of local variable type inference is introduced. By using the var keyword, the code writing process can be simplified. This article will introduce the use of the var keyword and demonstrate its effect of simplifying the code through sample code. 1. What is local variable type inference? Local variable type inference means that when declaring local variables, you can use the var keyword instead of explicit type declaration. The compiler will express
Local variable type inference in Java 10: How to use final var keyword in switch statement
Jul 31, 2023 pm 12:31 PM
Local variable type inference in Java10: How to use finalvar keyword in switch statement As the Java language continues to evolve, each new version introduces some new features and improvements. In Java10, one of the important new features is local variable type inference. This feature allows developers to use the var keyword instead of explicit type declarations, making the code more streamlined and readable. This article will explore how to use the finalvar switch in a switch statement.
Local variable type inference in Java 10: How to use var keyword in foreach loop
Jul 29, 2023 pm 03:21 PM
Local variable type inference in Java10: How to use var keyword in foreach loop Introduction: Java10 is an important version after Java9, which introduces many new features and improvements. One of the highly anticipated features is local variable type inference. In Java10, we can use the var keyword to declare local variables and let the compiler automatically infer the variable type based on the expression on the right. In this article, we will explore how to use
What is the default value of local variables in Java?
Aug 20, 2023 pm 09:41 PM
Local variables can be declared within methods, codeblocks, constructors, etc. in Java. Local variables are created when program control enters a method, code block, constructor, etc., and are destroyed when program control leaves a method, code block, constructor, etc. In Java, local variables have no default value. This means that they can be declared and assigned before the variable is used for the first time, otherwise, the compiler will throw an error. Example publicclassLocalVariableTest{ publicvoidprint(){ &am
Local variable type inference in Java 10: How to use var keyword in lambda expression
Aug 02, 2023 pm 04:25 PM
Local variable type inference in Java10: How to use the var keyword in lambda expressions Introduction: Java10 introduces a new feature of local variable type inference, which allows us to use the var keyword to infer the type of a local variable when declaring it. While this feature may not be necessary in most cases, in some cases it can improve code readability and simplicity. This article will focus on how to use the var keyword in lambda expressions to implement local variable type inference.
