1、upload.php
复制代码 代码如下:
2、uploadProcess.php
复制代码 代码如下:
//接收
$username=$_POST['username'];
$fileintro=$_POST['fileintro'];
//echo $username.$fileintro;
//获取文件信息
/* echo "
";";
print_r($_FILES);
echo "
*/
//获取文件的大小
$file_size=$_FILES['myfile']['size'];
if($file_size>2*1024*1024){
echo "";
exit();
}
//获取文件类型
$file_type=$_FILES['myfile']['type'];
if($file_type!="image/jpeg" && $file_type!="image/pjpeg"){
echo "文件类型只能是 jpg 格式";
exit();
}
//判断上传是否OK
if(is_uploaded_file($_FILES['myfile']['tmp_name'])){
//得到上传的文件 转存到你希望的目录
$upload_file=$_FILES['myfile']['tmp_name'];
//防止图片覆盖问题，为每个用户建立一个文件夹
$user_path=$_SERVER['DOCUMENT_ROOT']."/file/up/".$username;
if(!file_exists($user_path)){
mkdir ($user_path);
}
//$move_to_file=$user_path."//m.sbmmt.com/m/".$_FILES['myfile']['name'];
//防止用户上传用户名相同的问题
$file_true_name=$_FILES['myfile']['name'];
$move_to_file=$user_path."//m.sbmmt.com/m/".time().rand(1,1000).substr($file_true_name,strripos($file_true_name,"."));
//echo $upload_file.$move_to_file;
//中文要转码
if(move_uploaded_file($upload_file,iconv("utf-8","gb2312","$move_to_file"))){
echo $_FILES['myfile']['name']."上传成功";
}else{
echo "上传失败";
}
}else{
echo "上传失败";
}
?>
3、封装：
复制代码 代码如下:
class Upload{
public $upload_name; //上传文件名
public $upload_tmp_path; //上传文件保存到服务器的temp路径
public $file_size;
public $file_type;
public $file_save_path;
function __construct(){
$this->upload_name=$_FILES['myfile']['name'];
$this->upload_tmp_path=$_FILES['myfile']['tmp_name'];
$this->file_size=$_FILES['myfile']['size'];
$this->file_type=$_FILES['myfile']['type'];
$this->allow_file_type = array('jpeg','jpg','png','gif','bmp','doc','zip','rar','txt','wps','xlsx','ppt');
$this->file_save_path=$_SERVER['DOCUMENT_ROOT']."/file/up/";
}
public function upload_file($username){
//判断文件大小
if($this->file_size>2*1024*1024){
echo "";
exit();
}
//获取文件类型
/* if($this->file_type!="image/jpeg" && $this->file_type!="image/pjpeg"){
echo "文件类型只能是 jpg 格式";
exit();
}
*/ //获取文件的扩展名
$file_type=$this->getFileExt($this->upload_name);
if(!in_array($file_type,$this->allow_file_type)){
echo "上传文件类型格式错误";
exit();
}
//判断上传是否OK
if(is_uploaded_file($this->upload_tmp_path)){
//防止图片覆盖问题，为每个用户建立一个文件夹
$user_path=$this->file_save_path.$username;
if(!file_exists($user_path)){
mkdir ($user_path);
}
//$move_to_file=$user_path."//m.sbmmt.com/m/".$_FILES['myfile']['name'];
//防止用户上传用户名相同的问题
//$file_true_name=$_FILES['myfile']['name'];
$move_to_file=$user_path."//m.sbmmt.com/m/".time().rand(1,1000).substr($this->upload_name,strripos($this->upload_name,"."));
//echo $upload_file.$move_to_file;
//中文要转码
if(move_uploaded_file($this->upload_tmp_path,iconv("utf-8","gb2312","$move_to_file"))){
echo $this->upload_name."上传成功";
}else{
echo "上传失败";
}
}else{
echo "上传失败";
}
}
//获取文件的扩展名
public function getFileExt($filename){
$fileExt=pathinfo($filename);
return $fileExt["extension"];
}
}
?>
