Update drupal6's imagecache presets to Drupal7's image styles_PHP tutorial

Because the imagecache preset in drupal6 has been integrated into the core of drupal7, the next solution was proposed by Vladimir. You need to create a php file under your drupal root directory and copy the following code into it, execute this File.

[php]
define('DRUPAL_ROOT', getcwd()); 
require_once 
 
DRUPAL_ROOT . '/includes/bootstrap.inc'; 
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL); 
/////////////////////////////////////////////////

$result = db_query('SELECT * FROM {imagecache_action} where presetid = '.$preset['presetid'].' order by weight' ); 
    foreach ($result as $row ) { 
    $row=(array)$row; 
      $row['data'] = unserialize($row['data']); 
      $actions_cache[$preset['presetid']][] = $row; 
    }

$actions_cache[$preset['presetid']]) ? $actions_cache[$preset['presetid']] : array();
