Personally I would just use something like explode(), eg:

$sentence = "I am a PHP newbie";

$split_sentence = explode(' ', $sentence);

You could then reference the words thus:

$split_sentence[0] -> I

$split_sentence[1] -> am

$split_sentence[2] -> a

$split_sentence[3] -> PHP

$split_sentence[4] -> newbie

Or add print_r($split_sentence) to see the output.

Each() works if you've already gotten the words into an array such as that above, but you need to get them there first.

Ahh ....



$foo = array("bob", "fred", "jussi", "jouni", "egon", "marliese");

$bar = each($foo);

print_r($bar);
