PHP Variable Parameters

php can also declare functions that accept a variable number of parameters. Through three helper functions, func_num_args(), func_get_arg() and func_get_args().

<?php
function var_args(){
    $args = func_get_args();
    foreach($args as $arg){
        echo $arg,&#39;<br/>&#39;;
    }
    echo &#39;the num arguments of function is:&#39;,func_num_args();
}
var_args(&#39;hahah&#39;,&#39;lala&#39;,&#39;ddd&#39;);
