本函数是实验性的。本函数的行为,包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随
PHP 以后的发布而改变。使用本函数风险自担。  | 
   Commits an in-progress transaction on the specified connection resource and
   begins a new transaction. PHP applications normally default to AUTOCOMMIT
   mode, so db2_commit() is not necessary unless AUTOCOMMIT
   has been turned off for the connection resource.
  
注: 
    If the specified connection resource is a persistent connection, all
    transactions in progress for all applications using that persistent
    connection will be committed. For this reason, persistent connections are
    not recommended for use in applications that require transactions.
