strtr

  • Translating certain characters in a string in Ruby works pretty similar in Ruby to that in PHP. Ruby uses the String#tr method to perform translations. The Ruby method does not accept an array as an argument like it does in PHP.

    PHP

    $result = strtr("cat", "abc", "zyx");
var_export($result);
// => 'xzt'

    Ruby

    p "cat".tr("abc", "zyx")
# => "xzt"
