Description

array pg_meta_data ( resource connection, string table_name)

pg_meta_data() returns table definition for table_name as an array. If there is error, it returns FALSE

Example 1. Getting table metadata

<?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); $meta = pg_meta_data($dbconn, 'authors'); if (is_array($meta)) { echo '<pre>'; var_dump($meta); echo '</pre>'; } ?>
The above example would produce the following output:
array(3) { ["author"]=> array(5) { ["num"]=> int(1) ["type"]=> string(7) "varchar" ["len"]=> int(-1) ["not null"]=> bool(false) ["has default"]=> bool(false) } ["year"]=> array(5) { ["num"]=> int(2) ["type"]=> string(4) "int2" ["len"]=> int(2) ["not null"]=> bool(false) ["has default"]=> bool(false) } ["title"]=> array(5) { ["num"]=> int(3) ["type"]=> string(7) "varchar" ["len"]=> int(-1) ["not null"]=> bool(false) ["has default"]=> bool(false) } }
