Answer 1

$tok = strtok($string, " \n\t");

while ($tok !== false) {
    echo "<v>$tok</v>";
    $tok = strtok(" \n\t");
}

Answer 2

Use preg_replace to find words and replace them with wrapped version:

$string = preg_replace('/(\w+)/', '<v>\1</v>', $string);

Regular expression works as following:

• / is delimeter of regular exprtession, everything between /.../ is expression itself
• (...) - is capturing group which saves result of inner regexp into special array
• \w - means word character
• \w+ - means 1 or more word characters

In replacement \1 means value of first group saved in regexp.
