This video is made for learning about Function with Reference Arguments in PHP in Hindi.
PHP functions are similar to other programming languages. A function is a piece of code which takes one more input in the form of parameter and does some processing and returns a value.
Function arguments
Information may be passed to functions via the argument list, which is a comma-delimited list of expressions. The arguments are evaluated from left to right.
PHP supports passing arguments by value (the default), passing by reference, and default argument values. Variable-length argument lists are also supported.
