str_shuffle

  • There is no native function to shuffle the characters of a string in Ruby, but this can be accomplished easy enough by performing the following:

    1. String#split the string on every character
    2. Array#sort_by the characters at random
    3. Array#join the characters back into a single string

    PHP

    $result = str_shuffle('Hello');
var_export($result);
// => 'llHoe'

    Ruby

    p "Hello".split("").sort_by { rand }.join
# => "loHle"
