- The new null coalescing operator in PHP7: How to simplify the null detection operation of the code?
- The new null coalescing operator in PHP7: How to simplify the null detection operation of the code? When developing PHP applications, you often encounter situations where you need to check for nulls, such as obtaining form data entered by the user, obtaining data from database query results, etc. The previous writing method often required the use of the ternary operator or isset() function for judgment, and the code looked lengthy and not concise enough. In PHP7, a new null merge operator?? is added, which can simplify the null detection operation of the code and improve the readability and maintainability of the code. Specifically

- New scalar type declarations in PHP7: How to detect potential type errors in advance?
- PHP7 is an important version of the PHP programming language, which introduces a noteworthy new feature - scalar type declaration. Scalar type declarations allow developers to specify the required data types on the parameters and return values of functions and methods, allowing potential type errors to be discovered during the compilation phase. This article will introduce the new scalar type declaration feature in PHP7, and use specific code examples to illustrate how to detect potential type errors in advance. Before PHP7, PHP was a weakly typed language, and the parameters and return values of functions and methods were

- Type Hinting feature in PHP7: How to clarify the parameter type of a function?
- The TypeHinting feature was introduced in PHP7, which allows developers to explicitly specify the type of parameters in the function declaration. During the development process, we often encounter bugs caused by parameter type errors. TypeHinting can help us find these errors earlier and provide better type safety during the compilation phase. The use of TypeHinting is very simple. You only need to add the corresponding type before the parameters of the function declaration. Here is an example: functioncalcu

- The new null coalescing operator in PHP7: How to simplify the logical judgment of the code?
- A very practical operator has been added to PHP7: nullcoalescingoperator. This operator can be used to simplify logical judgments in the code, making the code more concise and readable. Traditional logical judgments are usually implemented using ternary operators or if-else statements. For example, if we want to get the value of a variable, if the variable exists, the value of the variable will be used, otherwise the default value will be used. Before PHP7, we might write code like this

- How to use PHP7's anonymous class to implement a simple factory pattern?
- How to use PHP7's anonymous class to implement a simple factory pattern? Factory pattern is a common design pattern that achieves the goals of high cohesion and low coupling by separating the instantiation process and usage process of objects. In PHP7, we can use anonymous classes to implement the factory pattern more concisely. In PHP7, we can use the new keyword "newclass" to define an anonymous class without explicitly defining a separate class. Definition and use of anonymous classes
