Perl Basics In Pictures

• Basics
• Variables
• Numbers
• Subroutines
• Logic & Loops
• Files

Here's what the relevant lines in the script do:

• @AcmeCars = ("Ford","Dodge","Chevy");

  Creates the array variable @AcmeCars and places the “Ford”, “Dodge”, and “Chevy” values into the array.

• foreach $thisCar (@AcmeCars){

  foreach tells the Web server to “loop” through the @AcmeCars array, going through each value in the array, one by one.

  $thisCar is a scalar variable: it tells the Web server to pull out each separate element in the @AcmeCars array.
