# PHP Variable Arguments

If we need to pass n number of arguments in a PHP function,  3 ellipses or dots are used inside the parenthesis and before the argument. In this way, PHP specifies a variable length argument function.

Example : Code for adding n numbers in PHP.

<!DOCTYPE html> <html> <body>   <?php function sum(...$num) {$sum = 0; foreach ($num as$x) { $sum +=$x; } return \$sum; } echo sum(12, 2, 38, 4); ?>   </body> </html>

Output
