PHP 事务处理数据实现代码

public function insertuser ($userarray){
foreach ($userarray as $key => $value) {
@$field .= "$key,";
@$content .= "'$value',";
}
$field = ereg_replace(',$', '', $field);
$content = ereg_replace(',$', '', $content);

$db = db_connect(); //连接数据库

$db->autocommit(false); //设置为非自动提交——事务处理

$sql1 = "insert into t_user (".$field.") values (".$content.")";
$result1 = $db->query($sql1);

$sql2 = "insert into t_userpost (f_username) values ('".$userarray['f_username']."')";
$result2 = $db->query($sql2);

if ($result1 && $result2) {
$db->commit(); //全部成功，提交执行结果
echo '提交';
} else {
$db->rollback(); //有任何错误发生，回滚并取消执行结果
echo '回滚';
}
$db->close();
}
