lt  php phpinfo      gt    Look under Configuration in the apache2handler in the Loaded Modules row     This is simple and works    lt  php foreach  apache get modules   as  module   echo   module lt br   gt       gt

Actually  just because a module is loaded  it does not necessarily mean that the directives has been enabled in the directory you are placing the  htaccess  What you probably need is to know  Does rewriting work  The only way to find out for sure is to do an actual test  Put some test files on the server and request it with HTTP  Good news  I created a library for doing exactly this  detecting various  htaccess capabilities   With this library  all you need to do is this  require  vendor autoload php   use HtaccessCapabilityTester HtaccessCapabilityTester    hct   new HtaccessCapabilityTester  baseDir   baseUrl   if   hct- gt rewriteWorks                 rewriting works     instead of  baseDir and  baseUrl  you must provide the path to where the test files are going to be put and a corresponding URL to where they can be reached  If you just want to know if the module is loaded  you can do the following  if   hct- gt moduleLoaded  rewrite                 mod rewrite is loaded  tested in a real  htaccess by using the  quot IfModule quot  directive     The library is available here  https   github com rosell-dk htaccess-capability-tester

For IIS heros and heroins   No need to look for mod rewrite   Just install Rewrite 2 module and then import  htaccess files

I like Christian Roy s solution         htaccess   lt IfModule mod rewrite c gt         Tell PHP that the mod rewrite module is ENABLED      SetEnv HTTP MOD REWRITE On      RewriteEngine on     RewriteCond   REQUEST FILENAME   -f     RewriteCond   REQUEST FILENAME   -d       The rest of your rewrite rules here   lt  IfModule gt    Then  you can check in your PHP code for      array key exists  HTTP MOD REWRITE     SERVER     No idea if this works also with IIS  I have no way to check  but the odds are good

If you re using mod php  you can use apache get modules    This will return an array of all enabled modules  so to check if mod rewrite is enabled  you could simply do  in array  mod rewrite   apache get modules       Unfortunately  you re most likely trying to do this with CGI  which makes it a little bit more difficult   You can test it using the following  though  strpos shell exec   usr local apache bin apachectl -l     mod rewrite       false   If the above condition evaluates to true  then mod write is enabled

Another idea  indeed more a dirty hack  regarding mod rewrite is server dependend an not necessary a php issue  Why not  if you have the possibillity  create a test directory put a  htaccess in it rewriting to test php  call the directory via http and check if you get the expected result you put in test php   Indeed  dirty

This is my current method of checking if Mod rewrite enabled for both Apache and IIS         --------------------------------------------------------------     MOD REWRITE CHECK    --------------------------------------------------------------                                           - By A H Abid    Define Constant for MOD REWRITE        Check if server allows MOD REWRITE  Checks for both     Apache and IIS          if  function exists  apache get modules    amp  amp  in array  mod rewrite  apache get modules           mod rewrite   TRUE  elseif  isset   SERVER  IIS UrlRewriteModule           mod rewrite   TRUE  else      mod rewrite   FALSE  define  MOD REWRITE    mod rewrite     It works in my local machine and also worked in my IIS based webhost  However  on a particular apache server  it didn t worked for Apache as the apache get modules   was disabled but the mod rewrite was enable in that server

Upload a file called info php with this code and run it    lt  php  phpinfo      Search for mod rewrite on the page  and see if you can find it under Loaded Modules

You can get a list of installed apache modules  and check against that  Perhaps you can check if its installed by searching for its  dll  or linux equivalent  file
