Is it possible to exclude specified GET parameters in apache access logs?(by W7

Question

I want to control my log printing but also it will make the parameter replaced with *symbol, if I execute a url which not including security parameter such as: 
http://localhost/meeting/op.do,   access.log must record it, but if I input a url which incuding security parameter such as 
http://localhost/meeting/import.php?cmd=admin&password=pass&userName=hsh&meetingID=123,  then the regular expression replacement must work and it will sove: 
http://localhost/meeting/import.php?cmd=****&password=****&userName=****&meetingID=****,   into logs,What should I go to achieve? remind:My develop environment is W7.thanks!

Answer 1

正则查找，这个security parameter
若cmd或password等任一个可做参考
只要查有无所参数就行了或是
if(isset($_GET['cmd']){$bFlag=true;}//等等
以上识别后，若为无安全参数，直接存在log里,若有，把url再来个
$str = 'http://localhost/meeting/import.php?cmd=admin&password=pass&userName=hsh&meetingID=123,';
$patten="/=(\w+)[&|,]/iUs";
$replacement = "****";
print  preg_replace($patten,$replacement,$str);
再存log
