DB::isError() -- Determines if a variable is a DB_Error object
Description
   Checks whether a result code from a DB method is a
   DB_Error object or not.
  
   You're generally better off using
   PEAR::isError()
   instead of the DB specific isError().
  
Parameter
   
- mixed
      $value
 
       Variable to check
      
 
  Return value
   boolean - TRUE if $value
   is a DB_Error object
  
Note
This function should be called
statically.
Example
Example 33-1. Using isError() <?php
require_once 'DB.php';
$db =& DB::connect('pgsql://usr:pw@localhost/dbnam');
if (PEAR::isError($db)) {
    die($db->getMessage());
}
?> |
