db2_commit — Commits a transaction

### 说明

function db2_commit(resource `$connection`): bool

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.

### 参数

`connection`
  A valid database connection resource variable as returned from db2_connect() or db2_pconnect().

### 返回值

成功时返回 `true`， 或者在失败时返回 `false`。
