I'm running a mysql database (managed through phpmyadmin) on a lubuntu virtual machine, which itself is on a mac 10.6. Everything was working smoothly until earlier, (and I didn't touch any part of the login code!) when I got the following error on my pages:
Erreur : SQLSTATE[28000] [1045] Access denied for user 'www-data'@'localhost' (using password: NO)
I don't understand where this error is coming from as I don't have a user called www-data on phpmyadmin and my files are supposed to be using the root account on the database:
$dbname = 'name';
$dbuser = 'root';
$dbpass = '*****';
$dbhost = 'localhost';
try{
$linkpdo = new PDO('mysql:host='.$dbhost.';'.$dbname.', '.$dbuser.' , '.$dbpass);
$linkpdo -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (Exception $e) {
die('Erreur : '.$e->getMessage());
}
After some googling I saw that people modified their config.conf file, but I don't know how or why.
Use a double quoted string and the correct parameters for the connect, its easier to build using a double quoted string and $variable
expansion.
$linkpdo = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass);
$linkpdo -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
<?php
$dsn = 'mysql:dbname=name;host=localhost';
$user = 'root';
$password = '*****';
try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
?>
Try this code. Checkout this link for more details http://php.net/manual/en/pdo.connections.php
The user and password are separate parameters, http://php.net/manual/en/pdo.connections.php .
So take out the concatanation here-> .', '.$dbuser.' , '.$dbpass
.', '.$dbuser.' , '.$dbpass
.
Connection should be:
$linkpdo = new PDO('mysql:host='.$dbhost.';dbname='. $dbname, $dbuser, $dbpass);
尝试这个 :
$linkpdo = new PDO('mysql:host='.$dbhost.';dbname='.$dbname , $dbuser, $dbpass);
