Once thing that happened to me was that the mysqld.pid file was deleted even though nothing happened to the server. This was an annoyance since it caused nagios to go critical because the pid was missing.

I assume that /etc/init.d/mysql would have had a fit had I tried to use it (i.e. server running but not pid file for the server).

Version I was using: Ver 5.1.56 for pc-linux-gnu on x86_64

Copy the following code into “mysql_test.php” and click save. (Make sure to replace the MYSQL_PASS constant with the MySQL Password you specified during the MySQL installation).

# Define MySQL Settings
define("MYSQL_HOST", "localhost");
define("MYSQL_USER", "root");
define("MYSQL_PASS", "password");
define("MYSQL_DB", "test");

$conn = mysql_connect("".MYSQL_HOST."", "".MYSQL_USER."", "".MYSQL_PASS."") or die(mysql_error());
mysql_select_db("".MYSQL_DB."",$conn) or die(mysql_error());

$sql = "SELECT * FROM test";
$res = mysql_query($sql);

while ($field = mysql_fetch_array($res))
{
$id = $field['id'];
$name = $field['name'];

echo 'ID: ' . $field['id'] . '’;
echo ‘Name: ‘ . $field['name'] . ”;
}

?>
Open up Internet Explorer and type in “http://localhost/mysql_test.php”. If the “mysql_test.php” page returns something similiar to:

ID: 1
Name: John

after run on broser:

Fatal error: Call to undefined function mysql_connect() in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\mysql_test.php on line 9

why given error in line no-9
plz help

Yup. I think the problem might be with your configuration. I use Mysql version 5.0.
and I get following message, I am not use of the warning message. Can you help

Hm. I think it worked for MySQL 4.1
I tested it with MySQL 5.0

It would,

Though I honestly do not expect little things as these to be given a lot of priority

I believe the proper way is to submit a feature request on bugs.mysql.com and ask them to add special options, say, –check_config to mysqld
