Function arguments – PHP

In PHP, a function argument is a value or variable that is passed to a function when it is called. The purpose of function arguments is to allow the function to receive input values that can be used to perform operations or calculations within the function’s code. Arguments can be passed by value or by reference, and functions can have multiple arguments with different data types. Function arguments in PHP are enclosed in parentheses following the function name, and multiple arguments are separated by commas. The values of the arguments can be accessed within the function using the variable names specified in the function declaration.
