Rewrite Rule To Detect Numbers Only

Question

I am trying to create a rewrite rule which will detect numbers only and forward them accordingly. I want the rewrite rule to be ignored if anything but numbers appears.

• /index.php - OK
• / - OK
• /42365 - rewrites to view.php?id=42365

What I have so far:

RewriteEngine on
RewriteRule ^([0-9]+)?$ view.php?id=$1 [L]

Answer 1

Remove the ? from the end of the ([0-9]+) group, which makes it optional. You must have numbers for the rewrite to occur:

RewriteEngine on
RewriteRule ^([0-9]+)$ view.php?id=$1 [L]
