I'm in troubles...
I have a web server apache/php under linux, also i have another server with SQL Server database under windows. I need to get access to SQL Server database from my apache/php.
What do i need, please help. I have no idea how to start.
**sorry for my english.
Could do with a bit more clarification but I'll try my best..
If you mean through the code, you would do it like this:
Create a new php file called "connect.php" and insert all of this code, replacing the tags like USERNAME with the correct details.
<?php error_reporting(E_ALL); ini_set('display_errors', 1);
// Create connection
$con = mysqli_connect("HOST","USERNAME","PASSWORD","DATABASE");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$select_db = mysqli_select_db($con, 'DATABASE');
if (!$select_db){
die("Database Selection Failed" . mysqli_error($con));
}
?>
Next, EVERY file that requires a connection to the database, simply add
include("connect.php"):
To it at the start of the page and it should be fine :)
I seriously recommend you read up a bit more though as you seem like a bit of a newb (we all started somewhere)!
Hope this is what you were after!
Look for dblib, you will need to add that driver.

I instal wamp server locally on my PC.I create a user registration form using php and mySQL database for pratice.I was able to connect to my mySQl data server and if i input data on the form and submit is work successfully.I normal experience at time when i access the user registration form it lost connection to my SQLdata server even though my wamp server is on.I will troubleshoot by changing some of the parameter by using mysqli_connect() to check if i will be prompted unsuccessful connection still nothing will show.When i check some other time it will work successfully.Please what may be causing this issue?
Run wampserver as administrator by right clicking wampserver.exe file. It may help.
Edit:
With the type of english you are using to produce the problem and giving no code is making it difficult to predict what the problem actually is. But I think there is something wrong with your mysqli connection file.
Add this code bit to the top of your registration.php file like this:
<?php
$connection = mysqli_connect('localhost','root','');
if(!$connection) {
die("Failed to connect" . mysqli_error($connection));
}
else {
echo "Connection Established";
}
$select_db = mysqli_select_db($connection, 'db2');
if(!$select_db) {
die("Database selection failed" . mysqli_error($connection));
}
else {
echo "Database selected";
}
?>
<?php
////rest of ur registration code goes here
Hello I've been making a site on my local server and I finished it so I'm moving everything over to my live server. I've made a database in phpmyadmin on it and I would like to connect to it. I feel like I have the wrong inputs though because it gives me this error.
This is my code for my database connection.
<?php
return $conn = mysqli_connect('localhost', 'gener105_nate', '(Password)', 'user_data');
if (!$conn) {
die("Connection Failed: " . mysqli_connect_error);
}
I didn't actually enter password I just think I shouldn't show it anyway I think I just have something mixed up since I'm new at this.
Oh and the database is located within a database grouping should i input the path to it?
You need to tell it to connect to gener105_user_data instead of just user_data
return $conn = mysqli_connect('localhost', 'gener105_nate', '(Password)', 'gener105_user_data');
I currently have a very big problem with PHP and mySQL. I moved a System I coded to a new Server. And while everything worked fine on the old Server, I had some problems on the new Server. Especially with mySQL. While I solved nearly all of them, I have one which I can't seem to get a hold on. And after 2 hours of trying i searched on the Internet for another two hours and updated my Syntax several times. But nothing seems to work. So now I'm here. I get a Connection to the database without a problem, but I can't update the values. I hope you can help me.
//Connect to mySQL Database
$verbindung = mysql_connect($server, $username, $passwort);
if (!$verbindung) {
echo "Couldn't connect: " . mysql_error();
}
$name=$_POST['fuehrer'];
$ident=$_POST['id'];
//Debugging
echo $name;
echo $ident;
$sql_befehl_0="UPDATE 'olgatermine' SET fuehrer = '".$name."' WHERE ID = '".$ident."';";
if (!mysql_query($verbindung, $sql_befehl_0)){
echo "Couldn't write to database";
}
//Close connection
mysql_close ( $verbindung );
What version of php use? Because in the newest versions of php the mysql functions are deprecated/removed, use instead mysqli.
Try to echo a mysqli_error at the end of the code, also mysql_error if your version of php accepts mysql functions.
If not version of php is the problem check this:
Wrong things what i see in your code..:
$sql_befehl_0="UPDATE 'olgatermine' SET fuehrer = '".$name."' WHERE ID = '".$ident."';"; // wrong
should be:
$sql_befehl_0="UPDATE `olgatermine` SET `fuehrer` = '".$name."' WHERE ID = '".$ident."';";
You need to run mysql_select_db('dbname') below line you do the mysql connection.
You can set at the first line of file:
ini_set('display_errors',1);
error_reporting(E_ALL);
to show all errors.
I've been scouring this site for 5 hours now trying to get this sorted, I rarely ask for help but this is one of the weirdest and most annoying things I've encountered.
First of all I'd like to say that this DID work fine, I have limited examples of what the cause is but I'll list them anyway.
Here's the full error message:
Fatal error: Call to undefind function mysqli_connect() in C:\wamp\www\game\connect.php on line 3
And here's the code
<?php
// Create connection
$con=mysqli_connect("localhost","root","","game");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$select_db = mysqli_select_db($con, 'game');
if (!$select_db){
die("Database Selection Failed" . mysql_error());
}
?>
Weird thing is, it was working completely fine and just suddenly stopped, this has happened more than once.
Here's what I've tried:
Checking the extensions are enabled -
Rebooting various times -
Setting the correct php path -
Using many example codes that "work" -
I also had some code that inputted data straight from phpdesigner into the database, which successfully worked, but that no longer works and I've made literally 0 changes.
The last time it stopped working, I filled out a registration form on my site as a test (that doesn't work either) and it suddenly went off. When filling in the form I click register and nothing happens besides a refresh.
Bit extra: In my httpd file the pfp and pfpinidir are as follows
php5_module"c:/wamp/bin/php/php5.5.12/php5apache2_4.dll"
PHPIniDir "C:\wamp\bin\apache\apache2.4.9\bin\php.ini"
Your mysqli extension might not be enabled. so u need to enable that.
You have two PHP binaries on your machine. One is connected to the Apache, and is the one u use when you surf to a web page.
The phpinfo() shows you which php.ini file is used by the web php binary. u need to edit this file and in it activate the mysqli extension
You're trying to connect to DB twice, plus you're mixing MySQL APIs with mysql_error(), they do not mix together.
The 4th parameter is the DB name which is what you've done in the first example.
Use either:
<?php
// Create connection
$con=mysqli_connect("localhost","root","","game");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>
or omit ,"game" from mysqli_connect() - while mysqli_error() requires DB connection parameter.
<?php
// Create connection
$con=mysqli_connect("localhost","root","");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$select_db = mysqli_select_db($con, 'game');
if (!$select_db){
die("Database Selection Failed" . mysqli_error($con));
}
?>
Probably been covered but I keep getting "connecting to the Wordpress database" which isn't what I'm after. In a nutshell I have a perfectly fine Wordpress site, I also have a MySQL database on another server which has some data I'm after. The code works fine on phpfiddle (is this the standard?) but whenever I try to use it on the Wordpress site, either with shortcodes or in the header.php it keeps hanging, throwing errors and won't connect to the DB, any ideas why?
Edit: To make things clearer, it's a meteorological database I want to connect to in order to pull things like Temperature from. Nothing native or related to Wordpress.
<?php
// Create connection
$con=mysqli_connect("ip","user","pass","db");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_close($con);
?>
Gives me this
Warning: mysqli_connect(): (HY000/2003): Can't connect to MySQL server on...
You should probably be looking at the WordPress WPDB class - https://codex.wordpress.org/Class_Reference/wpdb
For example:
<?php
$wpdb_dbconnect = new wpdb(user, pass, db_name, localhost);
$wpdb_dbconnect->show_errors();
$object = $wpdb_dbconnect->get_results("SELECT * FROM table_name");
foreach ($object as $person) {
echo $person->name . ', ';
}
?>
To connect to a second (and third, and forth...) database, I recommend HyperDB plugin.
