Undefine an Array in Perl

To undefine an array in Perl:

@jiji=("Hi","Hello","Hiya");

undef(@jiji);

-We create an array named jiji because typing jiji is easy. (Arrays start with @)
-We undefine @jiji with Perl's built-in undef function.

NOTE: You might think: why not just say @jiji=""; But that will not truly clear the array. When you put items back into that array, you will have an extra item at the beginning.



Copy and Paste Perl Code:

#!/usr/bin/perl

print "Content-type:text/html\n\n";

@jiji=("Hi","Hello","Hiya");

undef(@jiji);

print @jiji;

exit;
