Apache重写URL-修复附加字符串URL

Question

我在apache中有以下规则。

RewriteRule ^employees$ /all.php?fitler=employees  [L,QSA]

此页面有分页。

因此，第一页要正确，但是当我点击第2页（在分页按钮中）时，它将＆amp; p = 2添加到URL中，然后对于3rd Page im for of tot of tot &p=2&p=3

Then the 4th page is &p=2&p=4

Not sure how do I fix this 。

Update1:

Requested URL

https://example.com/empolyee

To be redirected

https://example.com/all/php?filter=employee

with pagination(let's say when I check page 3)

https://example.com/all/php?filter=employee&p=3
