Match a string from a "string"

Hi, i have a question here.

If i store a long string, how can i check if there are a word which i want to match.....

Hello..
to find an specific block of text or word within the value of a variable you can try this

let's say we have the following:

<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre> $browser = getenv("HTTP_USER_AGENT"); [/code]
you can use preg_match() func. to search for "MSIE" within $browser, like this:
<BLOCKQUOTE><font size="1" face="Verdana,Arial,Helvetica">code:</font><HR><pre> preg_match("/MSIE/i", "$browser"); [/code]
the "i" tells the script to match any instances, uppercase and lowercase etc...
