Below is a helpful function that will return the allowed values list for a Drupal CCK Integer Field as an Array.

Export Database to File

So today I wanted to learn how to export a Drupal database to a file quickly. Back in the day I would've logged in through cPanel and navigated to PHPMyAdmin, then manually select an export of the database and have to choose where to save the file. Not to mention all the previous steps listed would need to be preceeded by a Drupal cache flush (I don't like the cache inside a database backup). Typically this would've taken me about 5 minutes to complete, well my friends, no longer is that the case.

Drupal 7

Drupal 7

$header[] = array("data" => "Column Header Title 1");
$header[] = array("data" => "Column Header Title 2");

$row = array();
$row[] = "Row Column 1 Data"; 
$row[] = "Row Column 2 Data";

$rows = array();
$rows[] = $row;

$html = theme('table', array('header' => $header, 'rows' => $rows));

Drupal 6

Fatal error: Allowed memory size of # bytes exhausted (tried to allocate # bytes) in includes/database.mysqli.inc

To fix this problem, I opened my sites/default/settings.php and added the following php ini setting:
