PHP simulated URLRewrite

Source: Internet
Author: User
PHP simulates URLRewrite $ _ SERVER ['path _ info'] for more convenience. I checked some information about $ _ SERVER ['path _ info, modified the simulated URL Rewrite again.

The purpose is the same, but the class is not used. Instead, the obtained information is directly written to the predefined variables $ _ GET and $ _ SERVER ["QUERY_STRING, like yesterday's practice, $ _ SERVER ["R_QUERY_STRING"] is added to store the simulated QueryString.

And added a solution for the existence of/symbols in the URL. curly brackets are automatically added to indicate the difference. The test uses the $ _ GET value and generates Rewrite normally.

The content of the code is as follows:

Function BuildRewriteURL ($ string, $ UrlStyle = 0 ){
If (strpos ($ string ,'? ')){
$ StrArray = explode ('? ', $ String );
$ Page = $ StrArray [0];
$ ParaString = $ StrArray [1];
}
Else $ ParaString = $ string;
$ ParaString = str_replace ('? ', '', $ ParaString );
If (! Strpos ($ ParaString, '&') return $ this-> ParaString;
$ URLArray = explode ('&', $ ParaString );
For ($ I = 0; $ I <count ($ URLArray); $ I ++ ){
$ Para = explode ('=', $ URLArray [$ I]);
If (! Empty ($ Para [1]) {
If (! Empty ($ UrlString) $ UrlString. = '/';
If (strpos ($ Para [0], '/') $ Para [0] = '{'. $ Para [0]. '}';
If (strpos ($ Para [1], '/') $ Para [1] = '{'. $ Para [1]. '}';
$ UrlString. = $ Para [0]. '/'. $ Para [1];
}
}
Switch ($ UrlStyle ){
Case 1: $ AddString = '/'; break;
Case 2: $ AddString = ''; break;
Default: $ AddString = '. html'; break;
}
Return str_replace ('//', '/', $ Page. '/'. $ UrlString. $ AddString );
}

$ QueryString =! Empty ($ _ SERVER ['path_info'])? $ _ SERVER ['path_info']: str_replace ($ _ SERVER ["SCRIPT_NAME"], '', $ _ SERVER [" REQUEST_URI "]);
$ QueryString = str_replace (array ('"'," '",' <','> '), array (' % 22', '% 27 ', '% 3C', '% 3E'), $ QueryString );
If (strrpos ($ QueryString, "&") & strrpos ($ QueryString, "&") {// when the URL is in the original state
$ ParaArray = explode ('&', $ _ SERVER ["QUERY_STRING"]);
For ($ I = 0; $ I <count ($ ParaArray); $ I ++ ){
If (strpos ($ ParaArray [$ I], '=') + 1! = Strlen ($ ParaArray [$ I]) {
$ Para = explode ('=', $ ParaArray [$ I]);
If (! Empty ($ Para [1]) {
If (strpos ($ Para [0], '/') $ Para [0] = '{'. $ Para [0]. '}';
If (strpos ($ Para [1], '/') $ Para [1] = '{'. $ Para [1]. '}';
$ RequestURL. = '/'. $ Para [0]. '/'. $ Para [1];
}
}
}
$ _ SERVER ["R_QUERY_STRING"] = $ RequestURL;
}
Elseif (strrpos ($ QueryString, "/") {// when the URL is a simulated URL Rewrite
$ QueryString = str_replace ('. html', '', $ QueryString );
$ _ SERVER ["R_QUERY_STRING"] = $ QueryString;
Preg_match_all ("/{(. *)}/U", $ QueryString, $ matches );
For ($ I = 0; $ I <count ($ matches [0]); $ I ++ ){
$ QueryString = str_replace ($ matches [0] [$ I], rawurlencode ($ matches [1] [$ I]), $ QueryString );
}
$ ParaArray = explode ('/', $ QueryString );
For ($ I = 0; $ I <count ($ ParaArray); $ I = $ I + 2 ){
If (! Empty ($ ParaArray [$ I + 1]) {
If (! Empty ($ RequestURL) $ RequestURL. = '&';
If (strpos ($ ParaArray [$ I + 1], '% 2F') $ ParaArray [$ I + 1] = rawurldecode ($ ParaArray [$ I + 1]);
If (strpos ($ ParaArray [$ I + 2], '% 2F') $ ParaArray [$ I + 2] = rawurldecode ($ ParaArray [$ I + 2]);
$ StrArray [$ ParaArray [$ I + 1] = $ ParaArray [$ I + 2];
$ RequestURL. = $ ParaArray [$ I + 1]. "=". $ ParaArray [$ I + 2];
}
}
$ _ GET = $ StrArray;
$ _ SERVER ['query_string '] = $ RequestURL;
}
Unset ($ QueryString, $ ParaArray, $ Para, $ StrArray, $ RequestURL, $ matches, $ I );
