PHP清除HTML代码、空格、回车换行符的函数

 清除HTML代码、空格、回车换行符的函数如下

function DeleteHtml($str)  {   
         $str = trim($str);   
         $str = strip_tags($str,"");   
         $str = ereg_replace("	","",$str);   
         $str = ereg_replace("
","",$str);   
         $str = ereg_replace("
","",$str);   
         $str = ereg_replace("
","",$str);   
         $str = ereg_replace(" "," ",$str);   
          return trim($str);   
        }  

函数本身并没什么，有时候，会用就行。
