Hi Richard,
to count the words and check its length you could use explode() to split the
string into an array by a space (' '):
$words = explode(' ', $input);
$allowedWordLength = 20;
$tooLongWord = false;
$checkChar = '!';
$tooManyChars = false;
// loop through the array and check each word's length and char occurrence
foreach ($words as $word) {
if (strlen($word) > $allowedWordLength) $tooLongWord = true;
// check the occurrence of a special character in the word
if (substr_count($word, $checkChar) > 1) $tooManyChars = true;
}
// print an error if one of the words is too long
if ($tooLongWord) echo 'Error: Your words are too long!';
// print an error if the checked char occurred too often in one of the words
if ($tooManyChars) echo 'You had too many ' . $checkCar . ' in your input!';
The above code is not tested but should work. Hope this helps.
Regards, Torsten
