I am using following rewrite rule and its working fine :

1) RewriteRule ^([^/]*)/?([^/]*)/?([^/]*)/$ estates1.php?pageNum_Clusterb=$3&estname=$1&location=$2 [L]

but when add second code in my htaccess to use it , the second code not work :

2) RewriteRule ^([^/]*)/([^/]*)/$ estates1zone.php?pageNum_Clusterb=$2&zone=$1 [L]

if first code disable , second code work , but together not working second code .
appear any conflict , Can you guide How can fix it ?

Solution :

There is a conflict because the first rule matches the same pattern that the second rule matches against. ie. /foo/bar/ is matched by both rules.

Whilst you say the first rule is "working fine", it looks like it might be matching too much due to the optional slashes mid-pattern. It will match URLs of the form /foo/, /foo/bar/ and /foo/bar/baz/ - is that the intention?

The quick fix is to simply reverse these two directives, so the more specific rule (that matches exactly 2 path segments) is first. The "more generic" rule (that matches one, two or three path segments) would then follow.

However, I would also check that the first/original rule is working as intended. eg. Should a request for /foo/ be routed to estates1.php?pageNum_Clusterb=&estname=foo&location=?

Additionally, if you would like to do some further testing, give the htaccess tester tool a try. It allows you to specify a certain URL as well as the rules you would like to include and then shows which rules were tested, which ones met the criteria, and which ones were executed.
