How do i use php to detect whitespace ?

How do i use php to detect whitespace and convert text before whitespace and text after whitespace into array ? for e.g.

when someone types "hello world" into a text box, it inserts the words "hello" and "world" into an array. so array[0] will be "hello" and array[1] will be "world"

[sinisake]

$word="Hey Hey and hey again";
$word_array=explode(" ",$word);
print_r($word_array);
