New Comment:
This does not warrant new functions. What you are trying to do should
be done with arrays:
/**************************/
$countries = array("England", "Spain", "France", "Italy");
print "There are " . count($countries) . " countries competing";
print "The " . count($countries) . " are:";
for ($i=0; $i<count($countries); $i++) {
print $countries[$i];
}
/***************************/
if you have an input string like:
$string = "England Spain France Italy";
you can make an array of it:
$countries = preg_split("/\s+/", $string);
Still, the proposed functions look like a good addition to the language
as people do not want to study regular expressions.

When I was coding the sample code with the $countries (above), I
realised that PHP also misses some other crucial functions for word
processing. These are basic word functions which I am used to having
in a powerful language.
Therefore, request changed to request words(), word(), wordindex(),
wordlength() functions.

Derek,
This function is EXTREMELY useful. The words() function is to strings
what the sizeof() function is to arrays! I cannot imagine living
without the sizeof() function when dealing with arrays; if I were
dealing with strings a lot I cannot imagine living without a words()
function.
Here's some example code which shows how elegant it can make string
use:
/**************************/
$countries = "England Spain France Italy";
print "There are " . words($countries) . " countries competing";
print "The " . words($countries) . " are:";
for ($i=0; $i<=words($countries); $i++) {
print word($countries, $i);
}
/***************************/
Of course, there are many other uses, but this I hope gives a flavour
for how handy and elegant such functionality is.

I wish to expand this request to suggest full support for word
processing in strings. This is something which is extremely useful (it
appears for example in REXX) when processing strings.
word (str, num)
Returns the num'th word from string str. If num is greater than the
number of words in str, the null string is returned.
wordindex (str, num)
Returns the character position of the first letter of the num'th word
in string str, or 0 if num is greater than the number of characters in
str.
wordlength (str, num)
Returns the length of the num'th word in string str, or 0 if num is
greater than the number of words in str.
words (str, num)
Returns the number of words in the string str.

In my opinion this function doesn't that much value to PHP.

I would strongly favour the name words() rather than word_count().
Though there might be arguments for consistency with other functions to
call it word_count(), I think that words() is the more natural name and
more easily rememebered.
if (words($mystring) > 1) do_something();
You talk abouts "words" in a string and not "word count" in a string.
