Return Value

This built-in function returns TRUE if every character in the text creates some sort of whitespace, otherwise FALSE. Apart from the blank character, this also includes tab, vertical tab, line feed, carriage return and form feed characters.


Try out the below example -

   $strings = array('\n\r\t', '\test123' );
   foreach ($strings as $test) {
      if (ctype_space($test)) {
         echo "$test consists of all whitespace characters. \n";
      }else {
         echo "$test does not have all whitespace characters. \n";


When the above code is executed, it will produce the following result -

\n\r\t does not have all whitespace characters.
\test123 does not have all whitespace characters.
