How to find the length of a string

Just out of being bored I decided to share some really basic source code. Here’s how to find the lenght of a text in my three favorite languages:


$s = "simple php programming";
$length = strlen($s);


var s = "simple javascript programming";
var length = s.length;

(Visual) Basic

dim s as string
dim length as integer

s = "simple basic programming";
length = len(s);

    The JavaScript version has a trivial bug. It should be «var length = s.length». length is a straightforward property, not a method to be invoked.
