- Spaceship operator in PHP7: How to compare the size of two expressions?
- Spaceship operator in PHP7: How to compare the size of two expressions? In PHP7, a new operator was introduced called the Spaceship operator (<=>). This operator compares the size of two expressions and returns the result suitable for sorting purposes. Traditionally, when comparing the size of two expressions in PHP, we use comparison operators (>, <, =). However, these operators can only compare the magnitude of two expressions and return a Boolean value

- 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

- 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
