Two questions

I got two questions both about php, is there a way to turn numbers into percents, like .21910 = 22%? Is there a way to check for posting fields, like if someone makes an html form and has 2 fields in it, the script will store the info of these 2 fields to 2 vaiables witout having to manually put $_POST[name] in the script?

To turn to percent:-

$number = 0.21910;
$percent_number = round($number*100);

question2:
what exactly do u want? the script should handle the $_POST[name] itself and write it to file without u having to code?
well, nice idea for research work to make a device that is attached to the brain and it writes the code for everything u think. cool stuff!!!

With the rounding is there a way to round to a certain place like .2919 = .292?

Yes. To round .2919 to .292 you'd use
round(.2919, 3);

how would I format the output of a number, like if it = 0.75 then it outputs .750?

Maybe this will be of help to you:

PHP: number_format

printf("%0.3f",$number) can also do it
