大家好，我编写了一个类来连接 MSSQL/Azure 数据库并支持事务。
希望这对大家有所帮助！
<?php
class pdo_dblib_mssql{
private $db;
private $cTransID;
private $childTrans = array();
public function __construct($hostname, $port, $dbname, $username, $pwd){
$this->hostname = $hostname;
$this->port = $port;
$this->dbname = $dbname;
$this->username = $username;
$this->pwd = $pwd;
$this->connect();
}
public function beginTransaction(){
$cAlphanum = "AaBbCc0Dd1EeF2fG3gH4hI5iJ6jK7kLlM8mN9nOoPpQqRrSsTtUuVvWwXxYyZz";
$this->cTransID = "T".substr(str_shuffle($cAlphanum), 0, 7);
array_unshift($this->childTrans, $this->cTransID);
$stmt = $this->db->prepare("BEGIN TRAN [$this->cTransID];");
return $stmt->execute();
}
public function rollBack(){
while(count($this->childTrans) > 0){
$cTmp = array_shift($this->childTrans);
$stmt = $this->db->prepare("ROLLBACK TRAN [$cTmp];");
$stmt->execute();
}
return $stmt;
}
public function commit(){
while(count($this->childTrans) > 0){
$cTmp = array_shift($this->childTrans);
$stmt = $this->db->prepare("COMMIT TRAN [$cTmp];");
$stmt->execute();
}
return $stmt;
}
public function close(){
$this->db = null;
}
public function connect(){
try {
$this->db = new PDO ("dblib:host=$this->hostname:$this->port;dbname=$this->dbname", "$this->username", "$this->pwd");
} catch (PDOException $e) {
$this->logsys .= "Failed to get DB handle: " . $e->getMessage() . "\n";
}
}
}
?>
