2.字符串截取類

*$start:從哪裏開始截取
*$len:截取長度
*/
function msubstr($str,$start,$len)//字符位置從0開始

//如果讀取的是雙字節字符，則一次要讀取兩個字節的長度，否則，會出現意外情況
if(ord(substr($str,$i,1))>0xa0)

$i++;
}
else｛
$tmpstr.=substr($str,$i,1);
｝
}
$tmpstr = (strlen($str) <= $len) ? $tmpstr : $tmpstr."...";
return $tmpstr;
}
?>
3.表單類
<?php
//////////////////////////表單類///////////////////////
class form
{
private $action;
private $method;
private $enctype;
private $id;
private $name;
private $sty; //表單樣式

4.文件上傳類
<?PHP

*
*/
class uploadfile

private $posarr = array(); //存放對應文件類型格式的數組

//php5構造函數

}
//目錄創建

}
//上傳文件

break;
}
}

if(is_array($va)){
foreach($this->filearr['error'] as $p => $error){
//沒有錯誤發生
if($error == UPLOAD_ERR_OK){

$pos = strrchr($name,".");
if(!in_array($pos,$this->posarr)){
echo "<script language='javascript'>alert('你上傳的文件格式不對吧？^-^');history.go(-1);</script>";
exit();
}
$rename = date("YmdHis").$p.$pos;
$path = $this->root.$rename;
move_uploaded_file($tmp_name,$path);
}
}
} else {
$tmp_name = $this->filearr['tmp_name'];
$name = $this->filearr['name'];
$pos = strrchr($name,".");
