$conn =mysql_connect ($host, $user, $pwd);
mysql_query ("SET
character_set_connection=gb2312,
character_set_results=gb2312,
Character_set_client=binary ", $conn);

if ($conn ==false)
{
echo " Server Connection Failed!
Please refresh and try again. ";
return true;
}
$databasename = "database";//DB name

Do
{
$con =mysql_select_db ($databasename, $conn);
}while (! $con);

if ($con ==false)
{
echo " Failed to open database!
Please refresh and try again. ";
return true;
}

?>

2.upload.php

3.uploadclass.php
Copy CodeThe code is as follows:
$uploaddir = "upfiles/";//Set File save directory note include/
$type =array ("JPG", "gif", "BMP", "JPEG", "PNG");//Set the type of file allowed to upload
$patch = "upload/";//path where the program is located

Get file suffix name function
function Fileext ($filename)
{
Return substr (STRRCHR ($filename, '. '), 1);
}
Generate Random file name function
function Random ($length)
{
$hash = ' cr-';
$chars = ' abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz ';
$max = strlen ($chars)-1;
Mt_srand (Double) microtime () * 1000000);
for ($i = 0; $i < $length; $i + +)
{
$hash. = $chars [Mt_rand (0, $max)];
}
return $hash;
}

$a =strtolower (fileext ($_files[' file ' [' name ']));
Determine file type
if (!in_array (Strtolower (fileext ($_files[' file ' [' name '])), $type))
{
$text =implode (",", $type);
echo "You can only upload the following types of files:", $text, "
";
}
Generate file name for target files
else{
$filename =explode (".", $_files[' file ' [' name ']);
Do
{
$filename [0]=random (10); Set the length of a random number
$name =implode (".", $filename);
$name 1= $name. " MCNCC ";
$uploadfile = $uploaddir. $name;
}

while (File_exists ($uploadfile));

if (move_uploaded_file ($_files[' file ' [' Tmp_name '], $uploadfile))
{
if (is_uploaded_file ($_files[' file ' [' Tmp_name ']))
{

echo "Upload failed!";
}
Else
{//Output picture preview
echo " Your file has been uploaded upload picture preview:
