mysqli_get_server_version

mysqli->server_version

(No version information available, might be only in CVS)

mysqli->server_version — Returns the version of the MySQL server as an integer

说明

Procedural style:

int mysqli_get_server_version ( mysqli $link )

Object oriented style (property):

mysqli
int$server_version;

The mysqli_get_server_version() function returns the version of the server connected to (represented by the link parameter) as an integer.

参数

link

Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

返回值

An integer representing the server version.

The form of this version number is main_version * 10000 + minor_version * 100 + sub_version (i.e. version 4.1.0 is 40100).

范例

Example#1 Object oriented style

<?php
$mysqli = new mysqli("localhost", "my_user", "my_password");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

/* print server version */
printf("Server version: %d\n", $mysqli->server_version);

/* close connection */
$mysqli->close();
?>

Example#2 Procedural style

<?php
$link = mysqli_connect("localhost", "my_user", "my_password");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

/* print server version */
printf("Server version: %d\n", mysqli_get_server_version($link));

/* close connection */
mysqli_close($link);
?>

上例将输出：

Server version: 40102
