Funcții PHP definite de utilizator în dezvoltarea WordPress

PHP defines a wide range of functions as reusable blocks of statements in the core language, and many are also available in various extensions. These functions are well documented in the online PHP documentation. Custom functions can be defined by the developer. A function will not run automatically when a page loads, it can be called from anywhere and anytime within the program. PHP supports type declarations on function parameters, which are applied at runtime.
