sqlite_busy_timeout -- SQLiteDatabase::busyTimeout — Set busy timeout duration, or disable busy handlers

### 说明

sqlite_busy_timeout ( resource `$dbhandle` , int `$milliseconds` ) : void

面向对象风格 (method):

public SQLiteDatabase::busyTimeout ( int `$milliseconds` ) : void

Set the maximum time, in milliseconds, that SQLite will wait for a `dbhandle` to become ready for use.

### 参数

`dbhandle`

  The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.

`milliseconds`

  The number of milliseconds. When set to 0, busy handlers will be disabled and SQLite will return immediately with a SQLITE_BUSY status code if another process/thread has the database locked for an update.

  PHP sets the default busy timeout to be 60 seconds when the database is opened.

  > Note:

  > There are one thousand (1000) milliseconds in one second.
