Definition and Usage
The join() function returns a string from the elements of an array.
The join() function is an alias of the implode() function.
Note: The join() function accept its parameters in either order. However, for consistency with explode(), you should use the documented order of arguments.
Note: The separator parameter of join() is optional. However, it is recommended to always use two parameters for backwards compatibility.
Syntax
join(separator,array)

<?php
