Get the Length of a Word or String in Perl

To get the length of a word or string in Perl:

$dr="This is a short sentence";

$ft=length($dr);

print $ft;

Which prints:
24


-We create a variable and name it $dr because we are lazy typers.
-We use Perl's built-in length function on our variable $dr and store it in our newly created variable $ft.
-We print $ft.


We could have also done:

$ft=length("Hiyas");

print $ft;

Which prints:
5


-This time we just put the word/sentence right into the length function.
-Since our word/sentence is not a variable, we must enclose it in quotation marks.



Copy and Paste Perl Code:

#!/usr/bin/perl

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

$dr="This is a short sentence";

$ft=length($dr);

print "$ft ";

$ft=length("Hiyas");

print $ft;

exit;
