<?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\n";
$fieldname = pg_field_name($res, $j);
echo "fieldname: $fieldname\n";
echo "printed length: " . pg_field_prtlen($res, $fieldname) . " characters\n";
echo "storage length: " . pg_field_size($res, $j) . " bytes\n";
echo "field type: " . pg_field_type($res, $j) . " \n\n";
}
?>
The above example will output:
column 0
fieldname: author
printed length: 6 characters
storage length: -1 bytes
field type: varchar
column 1
fieldname: year
printed length: 4 characters
storage length: 2 bytes
field type: int2
column 2
fieldname: title
printed length: 24 characters
storage length: -1 bytes
field type: varchar
