range

The range() function creates an array containing a range of elements in PHP, however in Ruby the Range object is used to handle ranges of integers or strings.

PHP

$chars = range('a', 'c');
print_r($chars);
// => array(0 => 'a', 1 => 'b', 2 => 'c')

Ruby

chars = 'a'..'c'
chars.each {|item| print "#{item}, " } 
# => a, b, c,
