I am trying to learn php on my own. Things were OK till i reach DB connection.
I am using NetBeans 8.1 and had installed xampp to set up mysql and apache server. But when i try to connect to DB using
$dbPassword = "PHPpassword";
$dbUserName = "PHPuser";
$dbServer = "localhost";
$dbName = "PHPFirstDB";
$connection = new mysqli($dbServer, $dbUserName, $dbPassword, $dbName);
print_r($connection);
Ideally i should be seeing $connection details but I am not able to see anything in the script output window. I have set runas : script(run in command line)
Can anyone help me here...
Try this code, it could be possible that the error is occurring but not being displayed.
ini_set('display_errors',1);
error_reporting(E_ALL ^ E_NOTICE);
$connection = new mysqli($dbServer,$dbUserName,$dbPassword,$dbName);
if (mysqli_connect_error()) {
die('Connect Error (' . mysqli_connect_errno() . ') '. mysqli_connect_error());
}
print_r($connection);

I have spent the last 2 hours trying to solve this problem. I keep getting this error when trying to connect my php script with mySqli that is all hosted on a WAMP local host.
https://pastebin.com/HrJsnspG
;extension_dir = "./"
; On windows:
extension_dir = "C:\PHP7\ext"
I have added my pastebin above that shows my php.ini file. I changed the extensions as people have suggested on stack overflow and removed the ';' but nothing has worked, i still get the error. I have also reinstalled my WAMP server.
Any further suggestions?
<?php
$servername = "localhost";
$username = "root";
$password = "";
//create connection
$conn = new sqli($servername, $username, $password);
//check fann_get_total_connections
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected Successfully";
?>
To connect properly with MySQLi you need to create an instance of mysqli class, enable error reporting and set the correct charset.
<?php
// Connection code
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$conn = new \mysqli('localhost', 'testuser', 'password', 'dbname');
$conn->set_charset('utf8mb4');
For more information see https://phpdelusions.net/mysqli/mysqli_connect#oop
here is the code that I am using:
$dbhost = "localhost:8080";
$dbuser = "root";
$dbpass = "";
$dbname = "test";
$conn = mysqli_connect($dbhost, $dbuser, $dbpass, $dbname);
if(! $conn){
die('Could not connect:'. mysql_error());
}
else{
echo "Connected Successfully";
}
?>
when I use include or require_once, I never get the echo "Connected successfully" I always receive the error.
This is for a university project, and in uni the windows computers connect right away, using the same code.
since i am using MacOSX is there anything i need to do?
My server is also running on bitnami MAMP
I've been trying to upload my PHP MySQL(in Dreamweaver) project to a free web-hosting site.
When I logged in, there is an error that appear in dbconn.php file.
The error is shown below:
and here's the code in my dbconn.php file:
<?php
/* php& mysqldb connection file */
$user = 1350048; //mysqlusername to db
$pass = "password"; //mysqlpassword to db
$host = "eskl.freeoda.com"; //server name or ipaddress
$dbname= 1350048; // db name in server freeoda
$dbconn= mysql_connect($host, $user, $pass);
if(isset($dbconn)){
mysql_select_db($dbname, $dbconn) or die("<center>Error: " . mysql_error() . "</center>");
}
else{
echo "<center>Error: Could not connect to the database.</center>";
}
?>
I would really appreciate if anyone can teach me how to solve this.. thanks in advance!
As Kerbholz already stated, don't use mysql_* functions, they are really outdated.
Instead use mysqli:
$servername = "eskl.freeoda.com";
$username = "1350048";
$password = "password";
$database = "1350048";
// Create connection
$conn = new mysqli($servername, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
For your error it got mostly something to do your host doesn't allow remote connections. Try to change the serverhost to localhost or 127.0.0.1
I've looked through StackOverflow for an answer to this and have so far come up empty handed. I know some have had a similar issue, but so far none of the responses to the issues have worked.
So I work on two sites, both of which are on the same host with the same PHP Admin set up (different accounts and domains, sites are not affiliated). One of them uses MySqli perfectly, without issues, while the other either gives a database selection failure, localhost access denied with password as "NO" or a blank page when I attempt to replace the MySql with MySqli.
The deprecated code:
$host = "LOCALHOST";
$usr = "USER";
$pwd = "PASSWORD";
$dbname = "DATABASE";
$connection = #mysql_connect($host,$usr,$pwd);
if(!$connection){
die("No connection.");
}
mysql_select_db($dbname,$connection);
The MySqli I am attempting (identical to the site that MySqli works perfectly on):
$host = "LOCALHOST";
$usr = "USER";
$pwd = "PASSWORD";
$dbname = "DATABASE";
$connection = mysqli_connect($host,$usr,$pwd);
if (!$connection) {
die("No connection.");
}
$db_select = mysqli_select_db($connection, $dbname);
if (!$db_select) {
die("Database selection failed: " . mysqli_error($connection));
}
So the PHP error codes did not work at all and it had nothing to do with the local host or port, so I first checked to make sure mysqli_connect was on. Next, I ran a simple test where I echoed a random word before each mysqli command.
echo 'Passed.';
global $c_mysqli;
$conn = new mysqli($host, $usr, $pwd, $dbname);
echo '<br>Passed global mysqli.';
I found that my second pass was not working, and then proceeded to do an error message. An error showed up then. However, nothing I did fixed the issue... then I realized that one of my files, the header file, is the meat and potatoes and if it were to fail then everything else would fail too.
Sure enough, one of my lines of code contained a mysql connection and not mysqli. Long story short, double check and triple check to make sure that all
$statement = mysql_query("STATEMENT");
$query = mysql_fetch_array($statement);
Appear as
$statement = $conn->query("STATEMENT");
$query = mysqli_fetch_array($statement);
I am very new to php. I am trying to make a sign up page with php. So simple but I can't. I've searched across google how to connect it. They said below.
<?PHP
$user_name = "root";
$password = "";
$database = "user";
$server = "127.0.0.1";
mysql_connect($server, $user_name, $password);
print "Connection to the Server opened";
?>
I've successfully created my user database with full set of data in phpmyadmin. And running Apache and Mysql in control panel. I set the password in phpmyadmin and I changed it in $password="mypassword";. But there is no print on my web page. I think the above code is correct and I am having problems before this state. Such as the location of my database, I don't where to put it or just created on myadmin is fine. Thank you for reading my problem and kindly advice me for the beginner course.
<?php
$user_name = "root";
$password = "";
$database = "user";
$server = "127.0.0.1";
// Create connection
$con=mysqli_connect($server, $user_name, $password, $database );
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
Try mysqli instead of mysql and here is why
no no . . sorry . My html path . . on desktop
PHP, in this context, is a server side programming language. You must request the script from a server that will pass it through a PHP interpreter before sending it to the browser.
Type http://localhost/etc/etc into the browser's address bar. Don't open the PHP program directly in your browser (e.g. by double clicking the file in Windows Explorer).
If you are going to use procedural style function calls with the mysqli interface:
$con = mysqli_connect('localhost','myuser','mypassword','mydb')
or die("Error " . mysqli_error($con));
If you are going to use object oriented style with mysqli interface:
$mysqli = new mysqli('localhost', 'myuser', 'mypassword', 'mydb');
Reference: http://php.net/manual/en/mysqli.construct.php
If you are going to use PDO interface
$dbh = new PDO('mysql:host=localhost;dbname=mydb', $user, $pass);
