New features of PHP functions include: fn anonymous function, which defines functions without using the function keyword. Arrow function syntax defines anonymous functions as one line of code. Inline closures define closures inline in function call expressions. Parameter destructuring, directly destructuring arrays or objects in function parameters. These new features allow PHP to integrate with other languages, such as executing embedded JavaScript code through the eval() function.
Guidelines for integrating new PHP function features with other programming languages
With the continuous development of the PHP language, new function features are constantly being introduced. These new features greatly expand the functionality of PHP, allowing it to be seamlessly integrated with other programming languages.
