In looking at the Sony/Ericsson user agents, I think changing it to 'erics' should work. Please let me know what you come up with also.

I just created a SQL Server function using C# and .NET to build a pre-screener before we hit WURFL and other device databases. This post directly influenced the final code. Thanks for the ideas! I can now do this right in a database query, thousands of user-agents in seconds.

Thanks!

detection for browsers in ASP(VBScript):

<%
str = Request.ServerVariables("http_user_agent")
if InStr(1, str, "msie", 1) 0 then
browserIE = "true"
elseif InStr(1, str, "firefox", 1) 0 then
browserFirefox = "true"
elseif InStr(1, str, "safari", 1) 0 then
browserFirefox = "true"
elseif InStr(1, str, "iphone", 1) 0 then
browserIPhone = "true"
end if

if browserIPhone "" then response.redirect ("index_iphone.asp")

%>

pretty long winded but effective none the less, hope it helps!!

Greg's Note: This is a browser "sniffer" looking for "Msie", "Firefox", "Safari", or "iphone" in the user_agent string and then setting a string related to that browser as true. You'll need to act upon whether browserIE, browserFirefox (which it sets to true for Firefox or Safari), or browserIPhone is true, not on whether a mobile browser has been detected. And if you base your action on just that, a lot of smaller browsers that are desktop-based, but don't use one of those 4 strings in their user_agent strings, will be treated as mobile browsers.

Also, unless you have a specific page for an IPhone at index_iphone.asp, you may want to take out the last line of code.

This is actually complex enough an answer to deserve its own post.

I'm just learning PHP.

Can you explain to me why you do the foreach loop -- rather than just formatting $uamatches directly in regex syntax?

Is this more efficient processing, or more organized for you, or avoids some possible error getting thrown?

Thanks!

Anyway, thank you from me aswell for this code snippet. Works like a charm

P.S.: it was interesting to find out that preg_match is actually faster than stripos. I always assumed it'd be the opposite

[Editor's Note: But in his follow-up, HeavyWave said he'd checked the script/demo with his phone, so it's a bit of a moot point.]

Sorry, i tried to digg ya. Great job man.

Nice script, thanks a lot.

Opera Mini (the java based version of Opera for mobile phones) is detected by the script.
