sqlite_busy_timeout

SQLiteDatabase::busyTimeout

(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)

sqlite_busy_timeout -- SQLiteDatabase::busyTimeoutSet 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.

返回值

没有返回值。

范例

Example #1 过程化风格

<?php
$dbhandle 
sqlite_open('sqlitedb');
sqlite_busy_timeout($dbhandle10000); // set timeout to 10 seconds
sqlite_busy_timeout($dbhandle0); // disable busy handler
?>

Example #2 面向对象风格

<?php
$dbhandle 
= new SQLiteDatabase('sqlitedb');
$dbhandle->busyTimeout(10000); // 10 seconds
$dbhandle->busyTimeout(0); // disable
?>

The PDO equivalent of this function would be PDO::setAttribute(PDO::ATTR_TIMEOUT);
