sqlite_busy_timeout

(PHP 5)

sqlite_busy_timeout

(no version information, might be only in CVS)

SQLiteDatabase->busyTimeout -- Set busy timeout duration, or disable busy handlers

说明

void sqlite_busy_timeout ( resource dbhandle, int milliseconds )

Object oriented style (method):

class SQLiteDatabase {

void busyTimeout ( int milliseconds )

}

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.

注: There are one thousand (1000) milliseconds in one second.

范例

例子 1. Procedural style

<?php
$dbhandle
= sqlite_open('sqlitedb');
sqlite_busy_timeout($dbhandle, 10000); // set timeout to 10 seconds
sqlite_busy_timeout($dbhandle, 0); // disable busy handler
?>

例子 2. Object oriented style

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