Php quick url rewriting instance code

Php quick url rewriting instance code

Only versions later than 5.30 can be used. it inherits the features of fast redirection in the previous version (separate classes, all use static calls) and adds a very important feature and attribute, you can call modules in other URLs to simplify the sharing of functions between modules or between pages .. Htaccess file syntax: # --------------. Htaccess start --------------- RewriteEngine on RewriteRule !.
