PHP defines a function usage example with a variable number of parameters, PHP example

This article describes the usage of a PHP function definition with a variable number of parameters. Share it with everyone for your reference. The specific analysis is as follows:

The function parameters in php do not need to be fixed, and there is no need to even define parameters. Use the func_get_args() function inside the function to obtain the parameter list. You can specify any parameters for the function when calling, which is very convenient

<&#63;php
 function addanything (){
  $total = 0;
  $args = func_get_args ();
  for ($i = 0; $i < count ($args); $i++){
   if (is_int ($args[$i])){
    $total += $args[$i];
   }
  }
  return $total;
 }
 echo addanything (1,5,7,8,11) . "<br />";
&#63;>

I hope this article will be helpful to everyone’s PHP programming design.
