pg_meta_data

(PHP 4 >= 4.3.0, PHP 5)

pg_meta_data --  Get meta data for table.

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)
  }
}
