Generate the php code of the Xunlei address

Based on our needs, we wrote a php Tutorial to generate three Download software addresses for the Thunder Express tornado, which are probably implemented using base64 encryption programs. The code is as follows.

<? Php
Function zhuanhuan (){
$ Urlodd = explode ('/', $ _ get ["url"], 2); // divide the link into two sections. // The first section is the first section, followed by the second paragraph
$ Head = strtolower ($ urlodd [0]); // php is case sensitive, which is first converted to lowercase. Otherwise, http: or thunder: is not easy to handle.
$ Behind = $ urlodd [1];
If ($ head = "thunder :"){
$ Url = substr (base64_decode ($ behind), 2,-2); // base64 decryption, remove the preceding aa and the following zz
} Elseif ($ head = "flashget :"){
$ Url1 = explode ('&', $ behind, 2 );
$ Url = substr (base64_decode ($ url1 [0]), 10,-10); // base64 decryption, remove the previous [flashget]
} Elseif ($ head = "qqdl :"){
$ Url = base64_decode ($ behind); // base64 decryption
} Elseif ($ head = "http:" | $ head = "ftp:" | $ head = "mms:" | $ head = "rtsp: "| $ head =" https Tutorial :"){
$ Url = $ _ get ["url"]; // The regular address only supports the http, https, ftp, mms, and rtsp transmission protocols. It seems that few other addresses are supported, A network disk like xx is actually based on base64, but some cannot be downloaded even after decryption.
} Else {
Echo "this page does not support this protocol currently ";
}
Return $ url;
}
If ($ _ get ["url"]! = Null ){
$ Url = zhuanhuan ($ _ get ["url"]);
$ Url_thunder = "thunder: //". base64_encode ("aa". $ url. "zz"); // base64 encryption, the same is true for the following 2
$ Url_flashget = "flashget: //". base64_encode ("[flashget]". $ url. "[flashget]"). "& aiyh ";
$ Url_qqdl = "qqdl: //". base64_encode ($ url );
}
?>
<Form action = cs. php method = get>
For www.111cn.net, enter the normal link or the URL of the fast train or tornado link:
<Input type = text name = "url" size = "80">
<Input type = submit value = "conversion">
</Form>
<P> actual address: <a href = "<? Php echo $ url;?> "Target =" _ blank "> <? Php echo $ url;?> </A>
<P> Thunder Chain: <a href = "<? Php echo $ url_thunder;?> "Target =" _ blank "> <? Php echo $ url_thunder;?> </A>
<P> express chain: <a href = "<? Php echo $ url_flashget;?> "Target =" _ blank "> <? Php echo $ url_flashget;?> </A>
<P> tornado chain: <a href = "<? Php echo $ url_qqdl;?> "Target =" _ blank "> <? Php echo $ url_qqdl;?> </A>
