二款php文件上传程序-PHP源码

$sort=12;
$f_type=strtolower("swf,jpg,rar,zip,7z,iso,gif");//设置可上传的文件类型
$file_size_max=200*1024*1024;//限制单个文件上传最大容量
$overwrite = 0;//是否允许覆盖相同文件,1:允许,0:不允许
$f_input="files";//设置上传域名称
foreach($_files[$f_input]["error"] as $key => $error){
$up_error="no";
if ($error == upload_err_ok){
$f_name=$_files[$f_input]['name'][$key];//获取上传源文件名

$uploadfile=$uploaddir.strtolower(basename($f_name));

$tmp_type=substr(strrchr($f_name,"."),1);//获取文件扩展名
$tmp_type=strtolower($tmp_type);
if(!stristr($f_type,$tmp_type)){
echo "";
$up_error="yes";
}

if ($_files[$f_input]['size'][$key]>$file_size_max) {

echo "";
$up_error="yes";
}

if (file_exists($uploadfile)&&!$overwrite){
echo "";
$up_error="yes";
}
$string = 'abcdefghijklmnopgrstuvwxyz0123456789';
$rand = '';
for ($x=0;$x<12;$x++)
$rand .= substr($string,mt_rand(0,strlen($string)-1),1);
$t=date("ymdhis").substr($gettime[0],2,6).$rand;
$attdir="./file/";
if(!is_dir($attdir))
{ mkdir($attdir);}
$uploadfile=$attdir.$t.".".$tmp_type;
if(($up_error!="yes") and (move_uploaded_file($_files[$f_input]['tmp_name']

[$key], $uploadfile))){

$_msg=$_msg.$f_name.'上传成功 ';


}
else{
$_msg=$_msg.$f_name.'上传失败 ';
}
}

}
echo "";
?>

第二款文件上传代码

$destination_path = '../../upfile/jianjulogo/';//getcwd().directory_separator;

$result = 0;

$target_path = $destination_path . basename( $_files['myfile']['name']);

if(@move_uploaded_file($_files['myfile']['tmp_name'], $target_path)) {
$result = 1;
}
echo $target_path;
sleep(1);

?>
