Connecting to MySql

Postby Murph » 05. December 2008 18:32

Excuse me that i don't speak German. I have one question. I am trying to use MySql for the first time. I have the following:

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_close($con);
?>
But when i run it shows HTTP 500 Internal server error. I have XAMPP installed on my PC so it should allow me to run MySql. But the PHP program shows error. I have used the example from W3C PHP tutorials http://www.w3schools.com/PHP/php_mysql_connect.asp

Hope someone can help.

Kind Regards,
Murph

Error 500 is not related to PHP (normally). Look inside this file:

xampp\apache\logs\error.log

there you will find the reason for this error.

Hi,
the log shows
[Fri Dec 05 17:10:19 2008] [error] [client 127.0.0.1] PHP Fatal error: Call to undefined function mysql_connect() in C:\\xampp\\htdocs\\testmysql.php on line 2

But surely mysql_connect() is a valid function. What could i be doing wrong. Hope you can help and thanks.

Open this file:

Code: Select all
C:\xampp\apache\bin\php.ini


and search for this line:

Code: Select all
;extension=php_mysql.dll


then remove the ; at the beginning, save the file and restart your Apache Server. Then try again your script.

Hi thanks for reply.
It had no ; on front of that line in the file. So what can i do. Just to say i can connect to mdb database and it works fine.
I have for that:
<?php
$dbq = str_replace("/", "\\", $_SERVER["DOCUMENT_ROOT"]) . "Database3.mdb";
if (!file_exists($dbq)) { echo "<br />No such file as $dbq"; }

$db_connection = odbc_connect("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$dbq", "ADODB.Connection", "password", "SQL_CUR_USE_ODBC");

$result = odbc_tables($db_connection);

# query the users table for name and surname
$query = "SELECT name, surname FROM table";


# perform the query
$res = odbc_exec($db_connection,"SELECT * FROM table ORDER BY name DESC");


?>

I would like to learn MySql and hope i can connect to a database that way. Hope you can help. Thanks again.

Which "php.ini" is your PHP using?

XAMPP allready include PHP. So there is no need for an other PHP installation. (only confusion)

Hi,
just to say that it shows
Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: YES) in C:\xampp\htdocs\mywebsite\indexMYSQL.php on line 126
Could not connect: Access denied for user 'root'@'localhost' (using password: YES)

The php is:
<?php
$con = mysql_connect("localhost","root","newpassword");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}if (mysql_query("CREATE DATABASE my_db",$con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}mysql_close($con);



?>

I changed the password using the localhost/security but it won't allow me to connect.

I understand if you can't help anymore.
