preg_split problem

[OBCENEIKON]

Hello, I am having a problem with preg_split. Here is my code

<?php
	$Results = file("output.txt");

// Remove spaces, put each entry in it own variable
$Final = preg_split("/[\s]+/", $Results);

echo "Results array<br>";
print_r($Results);
echo "<br>Final array<br>";
print_r($Final);
?>

The $Results array prints the file contents.
But the $Final array prints:
Final array
Array ( [0] => Array )
I have tried using preg_split("/\s+/", $Results); as well.
Any idea why its doing this?

Because preg_split results in a multidimesional array.

If all you're doing is splitting on words, you could use [man]str_word_count[/man].
