joinPath() - Combines Multiple Path Fragments

This function will combine all the path fragments provided as the argument and return the result. joinPath() will use the correct path separator for the current platform.

Arguments

Each argument is a fragment of the result path. You can provide as many arguments as needed.

Example

joinPath("/var/", "www", "html", "index.php");
Returns /var/www/html/index.php
joinPath("/var/", "/www/", "html/", "index.php");
Returns /var/www/html/index.php - excess '/' are not an issue
joinPath("/var/", "/www/", "", "html/", "", "index.php");
Again, returns /var/www/html/index.php - empty fragments are handled correctly
