本文实例讲述了php定义参数数量可变的函数用法。分享给大家供大家参考。具体分析如下:

php中的的函数参数可以不固定,甚至不用定义参数,在函数内部使用func_get_args()函数获得参数列表,调用时可以为函数指定任意参数,非常方便

<&#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;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
