What is the Ruby equivalent of PHP substr ()?

Question

What is the Ruby equivalent of a PHP expression

<?php echo substr("abcdefghijklm", 0, 5); ?>

Answer 1

Use parenthesis notation with the same two arguments as for substr .

 substring = bigstring[0,5] 

I usually recommended http://railsforphp.com/substr as a great way to find the Ruby / Rails equivalents for regular PHP functions, but it seems to no longer work online. This is unfortunate: /

Answer 2

Use the byteslice method

 "abcdefghijklm".byteslice(0, 5) => "abcde"
