Ausführliche Beschreibung
The main "DB" class is simply a container class with some static methods for creating DB objects as well as some utility functions common to all parts of DB.
Definiert in Zeile 101 der Datei adodb-pear.inc.php.
Dokumentation der Elementfunktionen
| apiVersion | ( | ) |
Return the DB API version
- Rückgabe:
- int the DB API version number
Definiert in Zeile 199 der Datei adodb-pear.inc.php.
{
return 2;
}
| assertExtension | ( | $ | name | ) |
Load a PHP database extension if it is not loaded already.
public
- Parameter:
-
$name the base name of the extension (without the .so or .dll suffix)
- Rückgabe:
- bool true if the extension was already or successfully loaded, false if it could not be loaded
Definiert in Zeile 361 der Datei adodb-pear.inc.php.

$dlext = (strncmp(PHP_OS,'WIN',3) === 0) ? '.dll' : '.so';

return false;

| connect | ( | $ | dsn, |
| $ | options = false |
||
| ) |
Create a new DB object and connect to the specified database
- Parameter:
-
$dsn mixed "data source name", see the DB::parseDSN method for a description of the dsn format. Can also be specified as an array of the format returned by DB::parseDSN. $options mixed if boolean (or scalar), tells whether this connection should be persistent (for backends that support this). This parameter can also be an array of options, see DB_common::setOption for more information on connection options.

| factory | ( | $ | type | ) |
Create a new DB object for the specified database type
- Parameter:
-
$type string database type, for example "mysql"
Definiert in Zeile 112 der Datei adodb-pear.inc.php.
{
include_once(ADODB_DIR."/drivers/adodb-$type.inc.php");

}
| isError | ( | $ | value | ) |
Tell whether a result code from a DB method is an error
- Parameter:
-
$value int result code
- Rückgabe:
- bool whether $value is an error
Definiert in Zeile 211 der Datei adodb-pear.inc.php.
{
if (!is_object($value)) return false;
$class = strtolower(get_class($value));
return $class == 'pear_error' || is_subclass_of($value, 'pear_error') ||
$class == 'db_error' || is_subclass_of($value, 'db_error');
}
| isWarning | ( | $ | value | ) |
Tell whether a result code from a DB method is a warning. Warnings differ from errors in that they are generated by DB, and are not fatal.
- Parameter:
-
$value mixed result value
- Rückgabe:
- bool whether $value is a warning
Definiert in Zeile 229 der Datei adodb-pear.inc.php.
{
return false;
/*
return is_object($value) &&
(get_class( $value ) == "db_warning" ||
is_subclass_of($value, "db_warning"));*/
