<?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";
}
?>

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
