如果install.php存在，则访问install.php，否则访问index.php

Question

Before accessing my php script, user needs to access install.php and configure the script. The install.php will delete itself after completion. After install.php is deleted, user must be able to access index.php

What I have tried:

RewriteEngine On
RewriteBase /myscript/
RewriteRule ^ install.php [E]

I am able to redirect the user to install.php but not to index.php if install.php is not present.

I dont know the RewriteCond to check if install.php is present:

RewriteEngine On
RewriteBase /myscript/
RewriteCond ?? ??
RewriteRule ^ install.php [E]

Any help is appreciated. BTW I am not at all good with .htaccess configurations.

UPDATE :

Thank you for comments and replies. Yes I know that I can redirect through my php script like:

if(file_exists('install.php')){
     header('Location: http://'.$domain.'/install.php');
}

But can we do the same with .htaccess ?

Answer 1

Try adding this to an .htaccess file in the myscript folder:

RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}/myscript/install.php -f
RewriteRule ^ install.php [L]

Explanation

• The condition checks if the file install.php exists in the myscript folder
• If the condition is met, the rule will rewrite any request (since the beginning of string anchor ^ will match any file) to install.php
