[PHP] Re: Problems with patterns

[Jason Barnett]

What kinds of phrases are you looking for?  If you want to know whether 
an *exact* phrase is going to appear in a block of text, just use 
strstr() or strpos(), they tend to be faster than regexes anyway.

http://www.php.net/strpos

function valid_phrase ($phrase, $search = 'text to search for') {
    return strpos($phrase, $search);
}
If you really want to use ereg though, you'll need to search for 
whitespace characters (or maybe just spaces, depending on your need). 
But I think strpos() will be fine for what you want to do.
