A Quick Review

• Perl is a server-side scripting language.
• Each Perl script must start with the shebang line, and must have the content-type line if it is going to produce HTML.
• We can use print to write HTML.
• Perl has three types of variables:
• scalar: starts with $
• array: starts with @
• hashes or associative arrays: start with %
• We can get data entered to a form and parse it ourselves, but the CGI.pm and cgi-lib libraries make life much easier.
• Now that we understand the basics of Perl, we'll look a little deeper into the language.
