PHP 5.6.0 released

mysql_get_server_info

(PHP 4 >= 4.0.5, PHP 5)

mysql_get_server_info取得 MySQL 服务器信息

说明

string mysql_get_server_info ([ resource $link_identifier ] )

mysql_get_server_info() 返回 link_identifier 所使用的服务器版本。如果省略 link_identifier,则使用上一个打开的连接。

Example #1 mysql_get_server_info() 例子

<?php
    mysql_connect
("localhost""mysql_user""mysql_password") or
        die(
"Could not connect: " mysql_error());
    
printf ("MySQL server version: %s\n"mysql_get_server_info());
?>

以上例子将产生如下输出:

MySQL server version: 4.0.1-alpha

An alternative to mysql_get_client_info() is to use the VERSION() function in MySQL language like:

<?php
$query
= mysql_query("SELECT VERSION() as mysql_version");
?>

The output is the same as mysql_get_client_info()

Here is something I put together because I needed a way to pull the MySQL version number from the server without actually having a connection.  This was due to being part of a server info screen prior to installation of a cms.  Users need to know if their MySQL is supported or not prior to installation right? :)

This will scrape the phpinfo page looking for the MySQL row that says Client API version and return the version number after it.  This could also be used to scrape just about anything from the phpinfo page. :)

ob_start();
phpinfo(INFO_MODULES);
$info = ob_get_contents();
ob_end_clean();
$info = stristr($info, 'Client API version');
preg_match('/[1-9].[0-9].[1-9][0-9]/', $info, $match);
$gd = $match[0];
echo 'MySQL:  '.$gd.' <br />';

This will output:
MySQL: 4.1.22 (which is the version on my server)

I know this is crude but it's the only thing I could come up with and there isn't anything like this info available online so here it is.  I suck at preg_match and it would be helpful if someone could modify the string here to stand the test of time.

That's better:

<?php
mysql_connect
('localhost', 'user', 'password') or
   die(
'Could not connect: ' . mysql_error());
$a = mysql_get_server_info();
$b = substr($a, 0, strpos($a, "-"));
echo
$b;
?>
