PHP 8.4.2 Released!

    mysql_stat

    (PHP 4 >= 4.3.0, PHP 5)

    mysql_stat — Get current system status

    Warning

    This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

    Description

    mysql_stat(resource $link_identifier = NULL): string

    mysql_stat() returns the current server status.

    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() had been called with no arguments. If no connection is found or established, an E_WARNING level error is generated.

    Return Values

    Returns a string with the status for uptime, threads, queries, open tables, flush tables and queries per second. For a complete list of other status variables, you have to use the SHOW STATUS SQL command. If link_identifier is invalid, null is returned.

    Examples

    Example #1 mysql_stat() example

    <?php
    $link     = mysql_connect('localhost', 'mysql_user', 'mysql_password');
    $status = explode(' ', mysql_stat($link));
    print_r($status);
    ?>

    The above example will output something similar to:

    Array
(
    [0] => Uptime: 5380
    [1] => Threads: 2
    [2] => Questions: 1321299
    [3] => Slow queries: 0
    [4] => Opens: 26
    [5] => Flush tables: 1
    [6] => Open tables: 17
    [7] => Queries per second avg: 245.595
)

    Example #2 Alternative mysql_stat() example

    <?php
    $link     = mysql_connect('localhost', 'mysql_user', 'mysql_password');
    $result = mysql_query('SHOW STATUS', $link);
    while (    $row = mysql_fetch_assoc($result)) {
    echo     $row['Variable_name'] . ' = ' . $row['Value'] . "\n";
    }
    ?>

    The above example will output something similar to:

    back_log = 50
basedir = /usr/local/
bdb_cache_size = 8388600
bdb_log_buffer_size = 32768
bdb_home = /var/db/mysql/
bdb_max_lock = 10000
bdb_logdir =
bdb_shared_data = OFF
bdb_tmpdir = /var/tmp/
...

    The following script can be used to clearly print out the results of mysql_stat().

    <?php
    mysql_connect    ("localhost", "username", "password");
    $array = explode(" ", mysql_stat());
    foreach (    $array as $value){
    echo     $value . "<br />";
    }
    ?>

    Outputs something similar to:

    Uptime: 698
    Threads: 1
    Questions: 4
    Slow queries: 0
    Opens: 19
    Flush tables: 1
    Open tables: 12
    Queries per second avg: 0.5

    if you need the complete status as outputted by the "show status" command. Try this function.
    <?
    function mysql_status($db=NULL) {
    if(!mysql_ping($db))
    $db=mysql_connect("localhost","user","password");
    $res=mysql_query("show status",$db);
    while (list($key,$value)=mysql_fetch_array($res))
    $sql[$key]=$value;
    return $sql;
    }
    ?>
