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.
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
