参考php上传

<?php

// 判断是否有同名文件存在,存在就重命名
// 用 . 分割文件名,譬如 test.gif
// 取后缀名 gif
// 取后缀名长度 3
// 后缀名长度 + . 的长度 4
// 文件名长度 8
// 取不含后缀的文件名长度 8 - 4
// 取不含后缀的文件名 test
// 文件名 + 时间 + 随机数 + 后缀名 test10789937739057.gif
// 复制文件
// 删除系统生成的临时文件

if (file_exists("temp/" . $userfile_name)) {
$arr = explode(".", $userfile_name);
$last = end($arr);
$last_len = strlen($last) + 1;
$all_len = strlen($userfile_name);
$clip_len = $all_len - $last_len;
$file_name = substr($userfile_name, 0, $clip_len);
mt_srand((double)microtime()*1000000);
$userfile_name = $file_name . mt_rand() . "." . $last;
}
if (copy($userfile, "temp/" . $userfile_name)) {
echo "<h1>上传文件成功!</h1><hr>";
}
else {
echo "<h1>上传文件失败!</h1><hr>";
}
unlink($userfile);

echo "文件路径:" . $userfile . "<br>\n";
echo "名称:" . $userfile_name . "<br>\n";
echo "大小:" . $userfile_size . " kb<br>\n";
echo "类型:" . $userfile_type . "<br><br>\n";

?>
