seems like you are using a windows-machine, so try '\r\n' instead of '\n'.

a little bit confusing with your interpunctation, maybe you can provide some
examples?
to your array: why not using a mono-dimensional array with your words as key
and the occurances as value?
$words = array(
'myWord1' => 5,
'myWord2' => 3,
...
);
or if you got your $word and $occurance in these vars:
$words[$word] = $occurance;

there are some articles about uploading files. if you got te file on your
server you can simply use the location in the next script:
$location = /path/to/my.file;
echo '<img source="'.$location.'" />';
(or: echo "<img source=\"$location\" />";)
