mysql_get_proto_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.
mysql_get_server_info
(PHP 4 >= 4.0.5, PHP 5, PECL mysql:1.0)
mysql_get_server_info — Get MySQL server info
Description
string mysql_get_server_info
([ resource $link_identifier
] )
Retrieves the MySQL server version.
Parameters
- link_identifier
-
The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an E_WARNING level error is generated.
Return Values
Returns the MySQL server version on success, or FALSE on failure.
Examples
Example #1 mysql_get_server_info() example
<?php
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
printf("MySQL server version: %s\n", mysql_get_server_info());
?>
The above example will output something similar to:
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()

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;
?>
