I realized in the explode example I had omitted the call to count (idea being if you didn't find any comma's, maybe you need to handle those situations differently): if (count($sections = explode($delimiter = ',', $string = $your_string)) > 1) echo $sections[0]; Although, if it doesn't matter, you could just do: echo current(explode(',', $your_string)); And, as mentioned above, strstr() is one simple call if you won't need the other sections: echo strstr($your_string, ',' true); Adam -- Nephtali: PHP web framework that functions beautifully http://nephtaliproject.com
