An easy one

But for some reason I can't figure it out.

I have a field that people enter the hard drive size and I want the number stored in a float field. If they enter '40.0 GB' that obviously will not work, so how do I strip off everything but integeres and decimals first?

Thanks for the help.

[StupidScript]

floatval([mixed string]);

Like:

$thisvar="40.0 GB";

$clean=floatval($thisvar);

 echo $clean;

Note that float'ing 40.0 results in 40. Float'ing 40.1 results in 40.1. Also, it doesn't matter whether there is a space in the string or not ... as long as it begins with the numeric value.

Sweet. I knew there was something easy but I couldn't find it on the php site. Thanks!
