PHP thunder, express, Tornado download dedicated link conversion code

Copy the code and save it as cs. php. To save it as another name, modify the line <form action = cs. php method = GET>.
Copy codeThe 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 :"){
$ 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 );}
