屬性

PDO::ATTR_* 常量中的一個。下列為應用到數據庫連接中的常量：

PDO::ATTR_AUTOCOMMIT
PDO::ATTR_CASE
PDO::ATTR_CLIENT_VERSION
PDO::ATTR_CONNECTION_STATUS
PDO::ATTR_DRIVER_NAME
PDO::ATTR_ERRMODE
PDO::ATTR_ORACLE_NULLS
PDO::ATTR_PERSISTENT
PDO::ATTR_PREFETCH
PDO::ATTR_SERVER_INFO
PDO::ATTR_SERVER_VERSION
PDO::ATTR_TIMEOUT

例1 取回數據庫連接屬性

<?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";
}
?>
