How can I check to see if a string var holds a number? Is regex the
only way to do this? For example I have code where the var could hold
"10" or "ten". If the string is a number, do one thing, if it isn't
do something else. is_int doesn't work, intval converts "ten" to a
number so that doesn't work....
Thanks!
