Removing Duplicates from array

[bluto374]

I am trying to remove duplicate values from $headout, but when I var_dump it I get the duplicate values. Not sure why this is happening.

<?php
$in = fopen("./converted_files/corrected_with_options_msrp.txt", "r"); 
$out = fopen("./converted_files/EPA_options.txt", "w");

while(($line = fgetcsv($in, 0, '|')) !== false)
{
   $headout = array($line[8]);
   $headout2 = array($line[9]);
   $output = array_unique($headout);
}

fclose($in);
fclose($out);

?>

Perhaps you forgot to var_dump $output instead?
