在添加索引之前，htaccess不会加载索引

Question

I am trying to remove folder from the URL and I did that, but the problem is when i visit domain.com it shows error 500, but if i add domain.com/index.php it will work.

RewriteEngine On
RewriteBase /insta/member/

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteCond %{REQUEST_URI} !/$
RewriteRule (.*) $1\.php [L]

RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+insta/member/pages/([^\s]+) [NC]
RewriteRule ^ %1 [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (?!^insta/member/pages)^(.*)$ /insta/member/pages/$1 [L,NC]

Answer 1

In this set of rules, looks like the requests are considered to always be files and if the request file name is not a file, then it adds .php to it. It is not always the case though. In apache 2.2 mode_rewrite

REQUEST_FILENAME : The full local filesystem path to the file or script matching the request, if this has already been determined by the server at the time REQUEST_FILENAME is referenced. Otherwise, such as when used in virtual host context, the same value as REQUEST_URI

Therefore, the REQUEST_FILENAME may be resolved to files, folders or directories (this may vary in other web services or other apache versions). In case of files the rules work otherwise it fails. For example //domain.com will be resolved to the document root. But //domain.com/index.php will be resolved to the index.php file in the document root. To avoid these kind of confusions, all three possibilities should be considered, generally speaking. Also the REQUEST_FILENAME may be a file by itself without .php like //domain.com/my_styles.css. In that case the rules fail too. Following set of rules should work

    RewriteEngine On
    RewriteBase /insta/member/

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME}.php -f
    RewriteCond %{REQUEST_URI} !/$
    RewriteRule (.*) $1\.php [L]

    RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/+insta/member/pages/([^\s]+) [NC]
    RewriteRule ^ %1 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule (?!^insta/member/pages)^(.*)$ /insta/member/pages/$1 [L,NC]

Edit: Explanation for first set of rules is that it is checking if the resolved filename part of the request is not a directory, link or file and "filename.php" is a file and it is not ending with forward slash then add .php to the request.

Answering to the question in comment about pretty url:

To achieve pretty url you need to know the application routing. For removing a GET parameter from query string like ?checking=value rule should be like following

RewriteRule (.*)/checking/(.*)$ $1?checking=$2 [L]

It will be like following to combine with the above rules

    RewriteEngine On
    RewriteBase /insta/member/

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule (.*)/checking/(.*)$ $1\.php?checking=$2 [QSA,L]
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteCond %{REQUEST_FILENAME}.php -f
    RewriteRule (.*) $1\.php [QSA,L]

Then $_GET values for following examples would be

    http://localhost/insta/member/test
    array (size=0)
      empty

    http://localhost/insta/member/test?checking=value
    array (size=1)
      'checking' => string 'value' (length=5)       

    http://localhost/insta/member/test/checking/value
    array (size=1)
      'checking' => string 'value' (length=5)

    http://localhost/insta/member/test/checking/value?second=2
    array (size=2)
      'checking' => string 'value' (length=5)
      'second' => string '2' (length=1)

Finally, here is the specific rule for check/ig/value to check?ig=value going to check.php?ig=value

    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-l
    RewriteRule (.*)/(.*)/(.*)$ $1.\php?$2=$3 [QSA,L]

Sample output for GET

    http://localhost/insta/member/check/ig/value
    array (size=1)
      'ig' => string 'value' (length=5)
