trim

  • Stripping whitespace from the beginning and end of a string is done in Ruby using the String#strip method.

    PHP

    $result = trim(" \nhello world \n");
var_export($result);
// => 'hello world'

    Ruby

    p " \nhello world \n".strip
# => "hello world"

    PHP’s trim function has a second argument to specify the characters to strip. We can do this in Ruby using the String#gsub method.

    PHP

    $result = trim(" /Users/joe/work/ ", " /");
var_export($result);
// => 'Users/joe/work'

    Ruby

    chars = " /"
p " /Users/joe/work/ ".gsub(/^[#{chars}]+|[#{chars}]+$/, '')
# => "Users/joe/work"
