Example 1. Getting informations about fields

<?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 would produce the following 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

Note: This function used to be called pg_fieldname().
