Hello.
I received some code that has a section in which the variable $DB is established.
$DB =& new DB($db_username, $db_password, $db_dsn, false);
It does this by calling a function named DB, which is shown here below.
/**
* Constructor
*
* will set $DB->error and return false if login fails
*
* @param string $user
* @param string $password
* @param string $db_name
* @param bool $persistent Should this be a persistent db connection ?
* @param integer $int_mode
* @return bool
**/
function DB ( $user, $password, $db_name, $persistent=TRUE, $int_mode=OCI_COMMIT_ON_SUCCESS )
{
$this->_valid_connection = false;
$this->query_count = 0;
$this->debug = false;
$this->statement_handle = '';
$this->int_mode = $int_mode;
if ( $persistent )
{
$this->db_handle = OCIPlogon($user,$password,$db_name, 'AMERICAN_AMERICA.AL32UTF8');
} else {
$this->db_handle = OCIlogon($user,$password,$db_name, 'AMERICAN_AMERICA.AL32UTF8');
}
if ( !$this->db_handle )
{
$this->throwError(OCIerror());
Message::addAlert('Error: Unable to connect to Database');
return false;
}
return true;
}
/**
* Destructor
*
* this will only get called if you call it ( limitation of the current version of PHP )
* but don't worry... PHP cleans up after us anyway.
*
* @return void
**/
function _DB ()
{
OCILogOff($this->db_handle);
}
But I'm having trouble understanding exactly what it does and when run all I get is a blank page. Can somebody please explain why the DB function is not working correctly?
Thanks.
