php, pg_field_name, columns missing

[eric.chadbourne-Re5JQEeQqe8AvxtiuMwx3w at public.gmane.org (Eric Chadbourne)]

Hi All,

I'm trying to generate a report in CSV format.  I desire the column
names in the first row.  Oddly I'm outputing only the first few column
names.  Anybody in the mood to take a peak at my chicken scratch and
point out a mistake?  Many thanks.

<code>

    // do query
        $v_all_members_0 =3D "select * from members_50congress where
gym_name =3D '$v_gym_name';";
        $v_all_members_1 =3D pg_query($dbconn, $v_all_members_0) or
        die('Query failed: ' . pg_last_error());
        $rows =3D pg_num_rows($v_all_members_1);  // count up rows in que=
ry
        $rows =3D $rows -1;  // avoids an index not found error

    // write file
		$report_file_name =3D 'output_am_'.date("YmdHi").'.csv';
		$fp =3D fopen($report_file_name, 'w');
=09
	// get column names and write to file
	// TODO:  why the frack isn't this printing all column names?
		$i =3D 0;
		while ($i <=3D $rows) {
			fwrite($fp, pg_field_name($v_all_members_1,$i));
			$i++;
	=09
			if ($i <=3D $rows) {
				fwrite($fp, ',');
			} else {
				fwrite($fp, "\n");
			}
	=09
		}
=09
	// loop through rows and write to file
		$i =3D 0;
		while ($i <=3D $rows) {
			fputcsv($fp, pg_fetch_array($v_all_members_1,$i,PGSQL_NUM));
			$i++;
		}

		fclose($fp);

Many thanks!
