ruby - Check if string contains one word or more -


when looping through lines of text, neatest way (most 'ruby') if else statement (or similar) check if string single word or not?

def check_if_single_word(string)    # code here end  s1 = "two words" s2 = "hello"  check_if_single_word(s1) -> false check_if_single_word(s2) -> true

since you're asking 'most ruby' way, i'd rename method single_word?

one way check presence of space character.

def single_word?(string)   !string.strip.include? " " end

but if want allow particular set of characters meet your definition of word, perhaps including apostrophes , hyphens, use regex:

def single_word?(string)   string.scan(/[\w'-]+/).length == 1 end

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
