2. Perl Unary Operators

An operation with only one operand (a single input). The following are the Perl unary operators: !, -, ~, +,�\, &, and *.

  • ! performs logical negation which is "not"
  • - performs arithmetic negation if the operand is numeric.
  • ~ performs bitwise negation, that is 1's complement.
  • + has no semantic effect whatsoever, even on strings.
  • \ creates a reference to whatsoever follows.
  • & Address of operator.
  • * Dereference address operator.

6. Perl File Extensions (.pl, .plex, and .aspl)

.pl is the traditonal default extension for Perl although some developers will change the default extension in an effort to add an additional security level and .cgi is still popular as a Perl associated extension as well as .plex and .aspl.

  • .pl - Perl
  • .cgi - Common Gateway Interface
  • .plex - Perl Executable
  • .aspl - Active Server Perl

7. Perl Variables ($x = 0;)

Perl is a loosely typed language with only three types of variables: scalars, arrays, and hashes. Use $ for a scalar variable, @ for an array, or % for a hash (an associative array). The scalar variable type is used for anytype of simple data such as strings, integers, and numbers. In Perl, you identify and use a variable with a $ even within strings

10. Perl Development Tools

Many developers just use a text editor but you have to be careful when developing on Windows and deploying to Unix/Linix. Some Windows text editors including Notepad, and Microsoft Expression Web save text files in UTF-8 which is not compatible with Unix/Linux.

There are many Perl editors available including ActivePerl Pro Studio, and the free Perl Express. I usually use Perl Express.

Quick Start: Install Perl to IIS or Apache, install Perl Express then configure to use Perl, then install MySQL. For IIS 7, you will likely have to configure Hangler Mappings and add %s %s.

8. Perl Constants (use constant)

In PHP, you declare constants using the define keyword:

define("CONST_NAME", "Value");

Constants in PHP are case sensitive. A common standard in PHP is to use all-uppercase letters, with underscores to separate words within the name.
