I am having a user enter a phrase into a textbox, and then I need to
seperate the words he has typed into variables so I can use each one
in an sql statement. I know I will use the explode() function to do
this,
but how will I know how many variables I've created. For instance, if a
user types in 3 words seperated by spaces, how will I know i'll have
var[0] through var[2]? how about when they type in 2 words or 4 words?
How will I know how many words they have typed in? The only way I can
think of to do this is:

Use count() http://www.php.net/count
Counts the array ...
$arrayFoo = explode(" ", $theLine);
$countFoo = count($arrayFoo);
for($i = 0; $i < $countFoo; $i++){
echo $arrayFoo[$i];
}
