Yes, you described that, which is why I posted a link describing how to do it.

You can use regular expressions or string functions.

String functions: http://us2.php.net/manual/en/book.strings.php
Probably the simplest way to go about it is to explode() the string into an array of words.

eg:

PHP Syntax (Toggle Plain Text)
$array = explode(" ", $string);
$array = explode(" ", $string);

Then loop each array values (each word) counting characters with strlen().

For an intro to regular expressions see: http://www.regular-expressions.info/

It also goes into it in depth after a while. Regex is a really useful tool to learn, and is implemented similarly across programming languages. The flavor PHP currently uses is PCRE. http://www.pcre.org/

The PHP docs: http://www.php.net/pcre

Try this:

php Syntax (Toggle Plain Text)
<?
$string='Sign up for Facebook to connect with Jean Profession';
$word=explode(' ',$string);
$b=(count($word)-1);
$b=mt_rand (0,$b);
echo $word[$b];
?>
<?
$string='Sign up for Facebook to connect with Jean Profession';
$word=explode(' ',$string);
$b=(count($word)-1);
$b=mt_rand (0,$b);
echo $word[$b];
?>
