بإستخدام javascript:

function wordsCount (){
    var string = "this is a sample string for example";
    var words = string.split(" ");
    var length = words.length;
    return length;
}
wordsCount();

بإستخدام الـ PHP :

function countword($text) {
    $ct = explode(" ", $text);
    for($i = 0;$i <= count($ct);$i++){
        if($ct[$i] != "") {
            $ctn = $ctn + 1;
        }
    }
return $ctn;
}

echo countword("Hello World Hello World Hello World     ");

يمكن تجربة الكود هنا :

باستخدام ruby:

text = "this is a sample string for example"
text_array = text.split
print "#{text_array.length} words"

python

wordCount = lambda s : len([p for p in s.split() if p!= ""])

js

wordCount = function (s) { return (s.split(" ").filter(function(v) {return v!= ""})).length }

C#

delegate int D(string s);
....
D wordCount =  s => s.Split(' ').Count(p => !p.Equals(String.Empty));

Haskell

wordCount :: String -> Int
wordCount = length . words

Ruby

def wordCount(s)
    s.split.select{|p| p if p != ""}.length
end

طريقة أفضل عبر الـ PHP ، بإستخدام دالة ()str_word_count :

echo str_word_count("Hello World Hello World Hello World     ");

-

لتجربة :

Python 3

Number_Word= lambda words : len(words.split())

print(Number_Word(" hello  word   "))
