1.产生随机字符串函数
function random($length) {
$hash = ”;
$chars = ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz’;
$max = strlen($chars) – 1;
mt_srand((double)microtime() * 1000000);
for($i = 0; $i $length) {
if($sss){
$length=$length – 3;
$addstr=’ …’;
}
for($i = 0; $i 127) {
$wordscut .= $string[$i].$string[$i + 1];
$i++;
} else {
$wordscut .= $string[$i];
}
}
return $wordscut.$addstr;
}
return $string;
}
3.取得客户端IP地址
function GetIP(){
if (getenv(”HTTP_CLIENT_IP”) && strcasecmp(getenv(”HTTP_CLIENT_IP”), “unknown”))
$ip = getenv(”HTTP_CLIENT_IP”);
else if (getenv(”HTTP_X_FORWARDED_FOR”) && strcasecmp(getenv(”HTTP_X_FORWARDED_FOR”), “unknown”))
$ip = getenv(”HTTP_X_FORWARDED_FOR”);
else if (getenv(”REMOTE_ADDR”) && strcasecmp(getenv(”REMOTE_ADDR”), “unknown”))
$ip = getenv(”REMOTE_ADDR”);
else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], “unknown”))
$ip = $_SERVER['REMOTE_ADDR'];
else
$ip = “unknown”;
return($ip);
}
4.创建相应的文件夹
function createdir($dir=”)
{
if (!is_dir($dir))
{
$temp = explode(’/',$dir);
$cur_dir = ”;
for($i=0;$i”;
if(!empty($url))
$html .=””;
$html .=””;
$html .=”
”;
$html .=”
”;
$html .=”
| ”.$title.” |
”;
$html .=”
”.$message.”
”;
if (!empty($url))
$html .=”系统将在3秒后返回
如果您的浏览器不能自动返回,请点击[这里]进入”;
else
$html .=”[返回]“;
$html .=” |
|
”;
$html .=”
