call_user_func

  • In Ruby we use Object#send to invoke a method by name at runtime. The first argument is the name of the method we’re calling, and the rest is a variable list of arguments to send to that method similar to call_user_func in PHP.

    PHP

    function titleize($value, $delim='-')
{
    return strtolower(str_replace(' ', $delim, $value));
}
 
$result = call_user_func('titleize', 'my post title', '-');
var_export($result);
// => my-blog-post

    Ruby

    def titleize(value, delim='-')
  value.gsub(' ', delim).downcase
end
 
send(:titleize, "my post title", '-')
# => my-blog-post
