iwas的源代码INDEX.PHP处理所有的操作，和我平时的编程习惯不一致，觉得比较别扭，我不是很习惯一个大文件，上网找了找MVC分层的资料，感觉不错

用PHP开始你的MVC (一)整合你的站点入口
/*
     * 解析当前的访问路径，得到要进行动作
     */
    function _parsePath(){
     list($path, $param) = explode("?", $_SERVER["REQUEST_URI"]);
        $pos = strrpos($path, "/");
        $this->action = substr($path, $pos+1);
    }

我改为：

list($path, $param) = explode("?", $_SERVER["REQUEST_URI"]);
     $pos = strrpos($param, "=");
        $m=substr($param, $pos+1);

我一直使用正常，http://http://127.0.0.1/iwas/?action=img_show
但是现在有一个解析不正常了：http://127.0.0.1/iwas/?action=img_del&id=0&name=1124846170.bmp

看来看去，原来是 strrpos？！
strpos --  Find position of first occurrence of a string
int strpos ( string haystack, mixed needle [, int offset] )
Returns the numeric position of the first occurrence of needle in the haystack string. Unlike the strrpos(), this function can take a full string as the needle parameter and the entire string will be used.

strrpos --  Find position of last occurrence of a char in a string
int strrpos ( string haystack, string needle [, int offset] )
Returns the numeric position of the last occurrence of needle in the haystack string. Note that the needle in this case can only be a single character in PHP 4. If a string is passed as the needle, then only the first character of that string will be used.

最后索性改为 $this->action＝$action; 了事

This function takes in a string and a delimiter. It then builds an array of the data in between the delimiter then returns the array. I needed this function for something that I'm doing and thought it was somewhat useful.

function multiStrposArray($haystack, $needle){
  $array = array();
  $row  = 0;
  $var  = "";
  for ($i=0; $i<strlen($haystack); $i++) {
   if (substr($haystack, $i, 1)==$needle) {
     $array[$row] = $var;
     $row++;
     $var = "";
   } else {
     $var .= substr($haystack, $i, 1);
   }

  }
  if ($var) $array[$row] = $var;
  return $array;
}
