Examples

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 will 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) } }
