mysql_get_server_info — Get MySQL server info

Descrierea

string mysql_get_server_info ([ resource $link_identifier = NULL ] )

Retrieves the MySQL server version.

Parametri

link_identifier: Conexiunea MySQL. Dacă identificatorul legăturii nu este specificat, se presupune că este ultima legătură deschisă cu ajutorul mysql_connect(). Dacă nu este găsită nici o astfel de legătură, se va încerca crearea uneia prin apelul mysql_connect () fără argumente. În caz că nici o conexiune nu este găsită sau stabilită, se va genera o eroare de nivelul E_WARNING.

Valorile întoarse

Returns the MySQL server version on success sau FALSE în cazul eșecului.

Exemple

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());
?>

Exemplul de mai sus va afișa ceva similar cu:

MySQL server version: 4.0.1-alpha

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.

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;

?>
