mysqli::options

mysqli_options

(PHP 5)

mysqli::options -- mysqli_options — Set options

说明

面向对象风格

bool mysqli::options ( int $option , mixed $value )

过程化风格

bool mysqli_options ( mysqli $link , int $option , mixed $value )

Used to set extra connect options and affect behavior for a connection.

This function may be called multiple times to set several options.

mysqli_options() should be called after mysqli_init() and before mysqli_real_connect().

参数

link

仅以过程化样式：由 mysqli_connect() 或 mysqli_init() 返回的链接标识。

option

The option that you want to set. It can be one of the following values:

Valid options
Name Description
MYSQLI_OPT_CONNECT_TIMEOUT connection timeout in seconds (supported on Windows with TCP/IP since PHP 5.3.1)
MYSQLI_OPT_LOCAL_INFILE enable/disable use of LOAD LOCAL INFILE
MYSQLI_INIT_COMMAND command to execute after when connecting to MySQL server
MYSQLI_READ_DEFAULT_FILE Read options from named option file instead of my.cnf
MYSQLI_READ_DEFAULT_GROUP Read options from the named group from my.cnf or the file specified with MYSQL_READ_DEFAULT_FILE.

value

The value for the option.

返回值

成功时返回 TRUE， 或者在失败时返回 FALSE.

范例

See mysqli_real_connect().

注释

Note:

MySQLnd always assumes the server default charset. This charset is sent during connection hand-shake/authentication, which mysqlnd will use.

Libmysql uses the default charset set in the my.cnf or by an explicit call to mysqli_options() prior to calling mysqli_real_connect(), but after mysqli_init().

Example on using mysqli_options to increase size of max_allowed_packet for working with big blobs.

function dbConnect()
{
   $user = 'jomama';
   $pass = 'cartoon';
   $dbName = 'LifeCycle';
   $host = 'localhost';

   $mysqli = mysqli_init();
   mysqli_options($mysqli,MYSQLI_READ_DEFAULT_GROUP,
                                    "max_allowed_packet=50M");
   mysqli_real_connect($mysqli,$host, $user, $pass,$dbName)
                  or die ('<P>Unable to connect</P>');

   return $mysqli;
}

Here es little example to create a SSL Connection

<?php

$db = mysqli_init();

/*
When you want so use a separate cnf
$test = $db->options(MYSQLI_EAD_DEFAULT_FILE,'myother.cnf');
*/

$db->ssl_set('server-key.pem','server-cert.pem',
'cacert.pem',NULL,NULL);

$db->real_connct('localhost','root','','mydb');

//Here some query

$db->close();

?>
