PO(Apache Mod_Rewrite) Please help to condense my query
text
Body
copied!<p>I am trying to write a set of mod_rewrite rules to fulfill the following conditions:</p> <pre><code>1) /aaa (redirects to) --> /xxx_aaa.php 2) /aaa/ --> /xxx_aaa.php 3) /aaa?w=x&y=z --> /xxx_aaa.php?w=x&y=z 3) /aaa/?y=z --> /xxx_aaa.php?y=z 4) /aaa/bbb/ --> /xxx_aaa_bbb.php 5) /aaa/bbb/ccc/ --> /xxx_aaa_bbb_ccc.php 6) /aaa/bbb/cc12-34cc --> /xxx_aaa_bbb_cc12-34cc.php 7) /aaa/bbb/ccc/?y=z --> /xxx_aaa_bbb_ccc?y=z.php </code></pre> <p>The above list isn't exhaustive, but it gives you an idea of all the possible permutations I am aiming to cover. Namely, these are:</p> <p>1) Up to three subdirectory levels<br> 2) Works whether closing forward slash is present or not<br> 3) Pass GET query strings, if present</p> <p>This is that I use at the moment:</p> <pre><code>Options +FollowSymLinks RewriteEngine On RewriteBase / RewriteRule ^([0-9a-zA-Z\-]+)$ /xxx_$1.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/$ /xxx_$1.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/\?([0-9a-zA-Z\-=&]+)$ /xxx_$1.php?$2 [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)$ /xxx_$1_$2.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/$ /xxx_$1_$2.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/\?([0-9a-zA-Z\-=&]+)$ /xxx_$1_$2.php?$3 [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)$ /xxx_$1_$2_$3.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/$ /xxx_$1_$2_$3.php [L] RewriteRule ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-]+)/\?([0-9a-zA-Z\-=&]+)$ /xxx_$1_$2_$3.php?$4 [L] </code></pre> <p>And it seems to work just fine.</p> <p>But I can't help but think that there must be a much more elegant way of doing it - perhaps even condensing all the above into one single line.</p> <p>Any ideas? Any help much appreciated, thanks. :)</p>
