When using fopen(), it don't read the file itself, you need to loop through
the whole file in a similar way as when fetching rows from the database (see
my previous post) and you will read one line at the time.

You can choose to process the rows at the same time you fget() it or store
into an array. IMHO it's better to process one line at the time, as if the
uploaded file is a big one, then you will use more RAM if you store it in an
arrya.

This would be the case if you had loaded the whole file into one variable,
remember that this will consume twice as much ram as the file is big, one in
$my_text_from_uploaded_file and one in $myarray

$fp = @fopen("/path/to/uploaded/file/inputfile.txt", "r");
/*We check that we can open the file*/
if ($fp) {
/* we can read the file, let loop one row/line at the time */
while (!feof($fp)) {
$text_line = fgets($fp, 4096);
/*Do something with the $text_line which contains one line of the text*/
mysql_query("INSER INTO table VALUE('$text_line')");
}
/* we are at the end of the file, we close it */
fclose($fp);
echo "File has been stored in the database!<br>\n";
} else {
/* Error message as we couldn't open the file */
echo "We couldn't open the file!!!<br>\n";
}

No, you don't need an array, see the example above, it shows how you read one
line and inserts the date directly into the database. The examples this far
hasn't included much of error handling, I do suggest you do check at each step
that everything went okey, some problems you may be able to fix in the code,
others may not and you could make the script to mail you all errors, this way
you can manually insert those error lines.

Looking at your posts header it seems that could be quite expensive for you,
I'm living on east shores of the Lake Atlantic.
