Hello,
I am attempting to remove all the ^M characters in a file in VI.
The command I am using is

Any ideas why?

<?php
$dbconn = pg_connect("dbname=publisher") or die("Could not connect");
$res = pg_query($dbconn, "select * from authors where author = 'Orwell'");
$i = pg_num_fields($res);
for ($j = 0; $j < $i; $j++) {
echo "column $j
";
$fieldname = pg_field_name($res, $j);
echo "fieldname: $fieldname
";
echo "printed length: " . pg_field_prtlen($res, $fieldname) . " characters
";
echo "storage length: " . pg_field_size($res, $j) . " bytes
