PDO::getAttribute — Retrieve a database connection attribute
This function returns the value of a database connection attribute. To retrieve PDOStatement attributes, refer to PDOStatement::getAttribute().
Note that some database/driver combinations may not support all of the database connection attributes.
One of the PDO::ATTR_* constants. The constants that apply to database connections are as follows:
A successful call returns the value of the requested PDO attribute. An unsuccessful call returns null.
Beispiel #1 Retrieving database connection attributes
<?php
$conn = new PDO('odbc:sample', 'db2inst1', 'ibmdb2');
$attributes = array(
"AUTOCOMMIT", "ERRMODE", "CASE", "CLIENT_VERSION", "CONNECTION_STATUS",
"ORACLE_NULLS", "PERSISTENT", "PREFETCH", "SERVER_INFO", "SERVER_VERSION",
"TIMEOUT"
);
foreach ($attributes as $val) {
echo "PDO::ATTR_$val: ";
echo $conn->getAttribute(constant("PDO::ATTR_$val")) . "\n";
}
?>
The Oracle driver seems to not support PDO::getAttribute():
ociPHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[IM001]: Driver does not support this function: driver does not support getting attributes' in ...
If you want to retreive the Database type connection you can use the constant:
ATTR_DRIVER_NAME
$pdo_connection->getAttribute(constant("PDO::ATTR_DRIVER_NAME"))
Although i do not know if all drivers support this contant
