PHP is used to generate HTML. So anything you can type into your HTML file, PHP can output instead. However, your base assumption, that it's possible to guess reliably how many pixels wide a text string will be, is incorrect. Different people use different browsers and have different fonts installed, and get different results. The best you can do is test in multiple environments and average the results - or use GD to create GIFs containing the text, in which case you can control the size precisely because it's using the fonts on your server instead of on someone else's client. miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
