Hi, I'm still new to PHP (I've just got over the excitment of how the include statement works, its excellent it really is). Anyway, I need to create a PHP script. I have an input from a user (for arguments sake called $inputstring). Once the varible is in $inputstring, I need the script to decide whether its a numeric entry (e.g. 54) or whether its something else like text. If it's a number then I want it to stay in the varible $inputstring, and then it'll run some code I create, if its anything else like text or symbols I want $inputstring set to 1. I know this is probably easy to do, however I am new to PHP. Also if any of you could recomend good (interesting) books for training or websites that would be handy. Thanks in advance!

if (is_numeric ($inputstring)) { echo $inputstring . ' is a number'; } else { die (); } --- Site of the Day

ah sorry didnt read to the end. if (is_numeric ($inputstring)) { // do stuffs } else { $inputstring = 1; } For PHP learning, do googlesearch on phpfreaks, php.net, phpbuilder, sitepoint, computing.net, etc., like this. --- Site of the Day

thats fantastic - many thanks!

Shorthand version: $inputstring = (is_numeric($inputstring)) ? "$inputstring" : "1"; Do whatever with $inputstring now OnlyJC www.purple-fire.com
