[SOLVED] Validate that input string does not exceed word limit

Issue

I want to count the words in a specific string so that I can validate it and prevent users to write more than, for example, 100 words.

I wrote this function, but I don’t think it’s effective enough. I used the explode function with space as a delimiter, but what if the user puts two spaces instead of one? Can you give me a better way to do that?

function isValidLength($text , $length){
  
   $text  = explode(" " , $text );
   if(count($text) > $length)
          return false;
   else
          return true;
}

Solution

Maybe str_word_count could help

$Tag  = 'My Name is Gaurav'; 
$word = str_word_count($Tag);
echo $word;
