Hi all,
I have a question and I can't seem to get around the problem or finding a
total solution.
I have a DB with a list of entries, one of the tables has fields and one of
the fields is called the lookup_string field.
This field is used to checkup values when users enter the site (explained
below).
So basically what happens is that the user will enter the site and I will
get their user agent from the $_SERVER variable.
What I want to do is to find out which entries in the DB are present in the
useragent string.
Eg:
lookup_string (in db): "Mozilla"
useragent: 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15)
Gecko/20080623 Firefox/2.0.0.15'
So what I did was I used the locate function in my mysql query which gives
me the correct result set.
Now what I need to do is to ensure that the lookup_string is in the
useragent string and the CASE is the same: IE: Mozilla and not MOZILLA or
mozilla etc...
I am using the following If (however it fails because its part of the
useragent string and not the whole complete string therefore providing a
mismatch).
if(strcmp($userAgent, $lookup_string)==0){
//matches
}
Else
{
//doesn't match
}
Which way could I accomplish searching for the lookup_string in the
useragent and that it's the correct case?
Thanks in advance.
Angelo
strpos(), ereg() or preg_match() should work, take your pick. strpos()
most likely faster for this simple match.
if (strpos($userAgent, $lookup_string) !== false) {
//matches
} else {
//no matchy matchy
}
