Description:
------------
I wanted to read all the files from a directory and split them in diferent variables.

./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-mysql=/usr/local/mysql' '--with-pgsql=/usr/local/pgsql/' 

Reproduce code:
---------------
<?php
$ali = `ls`;
$oficial = explode(" ", $ali);
echo "oficial[0]<br>";
echo "oficial[1]<br>";
echo "oficial[2]<br>";
echo "oficial[3]";
?>


Expected result:
----------------
I would expect to see the files in the directory listed one below the other. 

Actual result:
--------------
I am seeing all the files in one line.... not in diferent lines. Only $oficial[0] is listed, the rest of variables are empty
