URL rewriting with PHP

Question

I have a URL that looks like   url com picture php id 51   How would I go about converting that URL to   picture php Some-text-goes-here 51   I think WordPress does the same   How do I go about making friendly URLs in PHP

this is an  htaccess file that forward almost all to index php    if a directory or a file exists  use it directly RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -l RewriteCond   REQUEST URI   -l RewriteCond   REQUEST FILENAME      ico css png jpg gif js    NC    otherwise forward it to index php RewriteRule   index php   then is up to you parse   SERVER  REQUEST URI   and route to picture php or whatever

You can essentially do this 2 ways   The  htaccess route with mod rewrite  Add a file called  htaccess in your root folder  and add something like this   RewriteEngine on RewriteRule    Some-text-goes-here   0-9      picture php id  1   This will tell Apache to enable mod rewrite for this folder  and if it gets asked a URL matching the regular expression it rewrites it internally to what you want  without the end user seeing it  Easy  but inflexible  so if you need more power   The PHP route  Put the following in your  htaccess instead   note the leading slash    FallbackResource  index php   This will tell it to run your index php for all files it cannot normally find in your site  In there you can then for example    path   ltrim   SERVER  REQUEST URI                Trim leading slash es   elements   explode       path                     Split path on slashes if empty  elements 0                               No path elements means home     ShowHomepage      else switch array shift  elements                  Pop off first item and switch       case  Some-text-goes-here           ShowPicture  elements      passes rest of parameters to internal function         break      case  more                   default          header  HTTP 1 1 404 Not Found            Show404Error        This is how big sites and CMS-systems do it  because it allows far more flexibility in parsing URLs  config and database dependent URLs etc  For sporadic usage the hardcoded rewrite rules in  htaccess will do fine though

PHP is not what you are looking for  check out mod rewrite

If you only want to change the route for picture php then adding rewrite rule in  htaccess will serve your needs  but  if you want the URL rewriting as in Wordpress then PHP is the way  Here is simple example to begin with   Folder structure  There are two files that are needed in the root folder   htaccess and index php  and it would be good to place the rest of the  php files in separate folder  like inc    root    inc     htaccess   index php    htaccess  RewriteEngine On RewriteRule  inc     index php RewriteCond   REQUEST FILENAME   -f RewriteRule        index php  QSA L    This file has four directives    RewriteEngine - enable the rewriting engine RewriteRule - deny access to all files in inc  folder  redirect any call to that folder to index php RewriteCond - allow direct access to all other files   like images  css or scripts   RewriteRule - redirect anything else to index php   index php  Because everything is now redirected to index php  there will be determined if the url is correct  all parameters are present  and if the type of parameters are correct   To test the url we need to have a set of rules  and the best tool for that is a regular expression  By using regular expressions we will kill two flies with one blow  Url  to pass this test must have all the required parameters that are tested on allowed characters  Here are some examples of rules    rules   array        picture      gt    picture    text           id  d             picture some-text 51       album        gt    album    album   w -                        album album-slug       category     gt    category    category   w -                  category category-slug       page         gt    page    page about contact                  page about     page contact       post         gt       post   w -                               post-slug       home         gt                                                       Next is to prepare the request uri    uri   rtrim  dirname   SERVER  SCRIPT NAME             uri         trim  str replace   uri        SERVER  REQUEST URI              uri   urldecode   uri      Now that we have the request uri  the final step is to test uri on regular expression rules   foreach    rules as  action   gt   rule         if   preg match        rule    i    uri   params                  now you know the action and parameters so you can             include appropriate template file   or proceed in some other way                         Successful match will  since we use named subpatterns in regex  fill the  params array almost the same as PHP fills the   GET array  However  when using a dynamic url    GET array is populated without any checks of the parameters         picture some text 51      Array                0      picture some text 51          text     some text          1     some text          id     51          2     51            picture php text some text id 51      Array                text     some text          id     51         These few lines of code and a basic knowing of regular expressions is enough to start building a solid routing system   Complete source  define   INCLUDE DIR   dirname    FILE         inc        rules   array        picture      gt    picture    text           id  d             picture some-text 51       album        gt    album    album   w -                        album album-slug       category     gt    category    category   w -                  category category-slug       page         gt    page    page about contact                  page about     page contact       post         gt       post   w -                               post-slug       home         gt                                                       uri   rtrim  dirname   SERVER  SCRIPT NAME             uri         trim  str replace   uri        SERVER  REQUEST URI              uri   urldecode   uri     foreach    rules as  action   gt   rule         if   preg match        rule    i    uri   params                  now you know the action and parameters so you can             include appropriate template file   or proceed in some other way                       include  INCLUDE DIR    action     php                 exit to avoid the 404 message          exit                nothing is found so handle the 404 error include  INCLUDE DIR    404 php
