PHP User Defined Functions
A function is a block of statements that can be used repeatedly in a program. It will not execute immediately when a page loads but will be executed by a call to the function. A user-defined function declaration starts with the word function. Syntax: function functionName() { code to be executed; }.
PHP Function Arguments
Information can be passed to functions through arguments. An argument is just like a variable. Arguments are specified after the function name, inside the parentheses.
PHP Returning Value
There might be cases where a user defined function, called by the main function returns a value to the main function. To let a function return a value, use the “return” statement.
