Hello,

I was wondering how to get the first character of a varible. For expamle if the varible $var contained the value test. How would you strip that varible down t.

How do I check to make sure that the first character in a varible only a letter or a number?

Thanks for your help,
Matt

To pick up just the first letter, use

substr($var,0,1)

The first number is the position in the string, starting with position 0 and the second number is the length of the string.

To test whether that character is a letter or number, use

substr($var,0,1) =~ /[0-9a-zA-Z]/

If you were willing to allow underscores, too, you could shorten it to

substr($var,0,1) =~ /\w/
