preg_split

• We split strings by a pattern in Ruby using the String#split method. As with String#gsub, we can also use this same method to split using a string instead of a regular expression. This means that split also performs the equivalent of the explode function in PHP.

  In this example, we create an array of the list of emails by splitting the string using the semi-colon and space as the delimiter.

  PHP

    $string = 'joe@example.com; walter@example.org';
    $result = preg_split('/;\s?/', $string);
   
    var_export($result);
    // array('joe@example.com', 'walter@example.org')

  Ruby

    string = 'joe@example.com; walter@example.org'
    result = string.split(/;\s?/)
   
    p result
    # => ["joe@example.com", "walter@example.org"]
