The difference instance code between JS and PHP passing variable parameters to a function

# JS Call function method for passing variable parameters

<script> function Test () {for (var i = 0;i < Arguments.length; i++) {alert (arguments[i]); }}//Call function Test (1, 2, 3, ' abc '); </script>

How PHP calls functions to pass mutable parameters

<?php//Method One//receive a series of parameters and output function Show_params () {//Get the number of pass parameters $count = Func_num_args (); 　　　　　　Traverse parameters and output each for ($i = 0; $i < $count; $i + +) {//get parameter $param = Func_get_arg ($i); Echo $param. 　　　　Php_eol; 　　}}//Call function Show_params (1, 2, ' Apple ', 3.14); 　　　　Method 2 function Show_params () {//defines an array of stored pass parameters $params = Array (); 　　　　Get all parameters $params = Func_get_args (); 　　　　$count = count ($params); 　　　　　　Iterate and output parameters for ($i = 0; $i < $count; $i + +) {echo $params [$i]; 　　　　Echo Php_eol; }}//Note: Method 2 performs slower than Method 1
