如何在PHP CGI上检查mod_rewrite

Question

I am on shared host and PHP is inatalled as CGI script and that is all the problem i am not able to find whether mod_rewrite if enable or not

Note: I don't have any root level access so i can't much do with Shell.

I have tried the following :
1) checked in phpinfo() where i came to know about that this is the wrong place to look for in PHP-CGI.

2) I have tried getting it from apache_get_modules which agi does not work in PHP-CGI :(
3) I have tried :

if (strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false) {
    // mod_rewrite is enabled
}

which is asking for path to apache and i dont have this info SHELL cant reply to me and $_SERVER has nothing.
4) I have checked with RewriteEngine On in .htaccess and after this my site is throwing 500 Internal server error may be because of RewriteEngine is not there, but i need this is written to show someone.

Any body has any idea how to check get this DONE.

Thanks

With PHP CGI there is no easy way to find out whether mod_rewrite is available or not on the server.

So, you need to find out it by making a test call to the server. You can use the following steps for this method,

1. Create a directory named mod_rewrite_test on the server.

2. Add .htaccess file in this directory with the following code,

   <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /mod_rewrite_test RewriteRule .* mod_rewrite_test.txt </IfModule>

   a. first line tells apache to execute the below code only if mod_rewrite is available,
   b. second line enables rewrite engine,
   c. third line sets rewrite base directory path which is from DOCUMENT_ROOT
   d. forth line returns the content of mod_rewrite_test.txt file to any request sent to mod_rewrite_test directory.

3. Create a file named mod_rewrite_test.txt in the same directory. Write ok in this file and save it.

4. Now, using CURL in your php script, call the URL similar to,

   http://www.your-domain.com/mod_rewrite_test/test.php and check the response.

   So, as per our .htaccess code, if mod_rewrite is active and working on the server, it will return the content of mod_rewrite_test.txt file ie ok even though the test.php file does not exists.

   Otherwise, it will return 404 - Page not found error.

To check if mod_rewrite module is enabaled, create a new php file in your root folder of your server. Enter the following

echo phpinfo();

And access file in your browser.
