Browser detection - Help...

[varmaa]

Hi,

In need of some help please. I am trying to write a script whereby some PHP will detect which version of MS Internet Explorer someone is using. If the version is lower than IE 5.0 they are redirected to a page. If not, then I need a statement to be echoed... and this is the part where I'm having the trouble! My else statement doesn't seem to be working...

Any help appreciated.

the variable you are looking for is HTTP_USER_AGENT ... php.net shows it being most commonly used in conjunction with get_browser()

The manual is great! 🙂 Always check there first. 😃

Have fun dude,

Thanks. That is what I used however, I can only get a part of it working.

The HTTP_USER_AGENT layer bit is okay but if someone is using a lower version of IE, I need a statement to be echoed -- this is the part I'm having problems with.

Here's what I have so far...

<?php

if (substr($HTTP_USER_AGENT,'>= MSIE 5.0'));{

header("302: Redirection");
header("Location:http://www.alocation.com");

}
else
{
	echo "Sorry, you need to upgrade";
}

?>

Thank you!!

im thinking the problem lies in you if() statement.

substr(string, start, stop) returns a string variable not a numeric variable. Therefore your if() would be more like...

if (substr($HTTP_USER_AGENT,3,4)=="MSIE 6.0")
{
header("302: Redirection");
header("Location:http://www.alocation.com");
}
elseif (substr($HTTP_USER_AGENT,3,4)=="MSIE 5.0" or substr($HTTP_USER_AGENT,3,4)=="MSIE 4.0")
{
echo "Sorry, you need to upgrade";
}

thats they way I would go about it... unless a more experience PHP user would know a better way... 😃

in any case i am at work and will check more later when I get home.
