URL重写或.htaccess无法正常工作

Question

I am trying to rewrite the url like http://test.com/1234 to http://test.com/index.php?a=1234

and my .htaccess file

    RewriteEngine On

    RewriteRule     /^[a-zA-Z0-9]/?$    index.php?key=$1    [NC,L]

but nothing is happening it simply shows object not found error, .htaccess file is already in the root directory so help needed P.S. I am a beginner in rewriting.

Answer 1

Try this rewrite rule:

RewriteEngine On
Options +FollowSymlinks
RewriteRule ^([a-zA-Z0-9]+)/?$ index.php?key=$1 [NC,L]

• You need the brackets to group characters and re-use them as the $1 parameter.
• You don't need the /
• If you have a pattern like [0-9] you need a * or + if you want to match more than one character.

Btw, if the key parameter only accepts numbers, use:

RewriteEngine On
Options +FollowSymlinks
RewriteRule ^([0-9]+)/?$ index.php?key=$1 [NC,L]
