PHP connection to MS SQL - php

I'm trying to connect my PHP webpage with my MS SQL database. I've got this code from the internet, but have tried others. All seems to come back with a problem with "mssql_connect".
I have tried (I think) everything and can not find out why it won't work.
My code is:
<?php
$myServer = 'SQL5008.Smarterasp.net,1433';
$myUser = '*****';
$myPass = '*****';
$myDB = '*****';
//connection to the database
$dbhandle = mssql_connect($myServer, $myuser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");
//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");
//declare the SQL statement that will query the database
$query = "SELECT id ";
$query .= "FROM tblEmployees ";
$query .= "WHERE CompanyID=3";
//execute the SQL query and return records
$result = mssql_query($query);
$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";
//display the results
while($row = mssql_fetch_array($result))
{
echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

Why dont you try using PDO. I use it with SQL SERVER daily. You will need the php sqlsrv extenstion though.
// instantiate the pdo object
try {
$Server = "localhost";
$User = "username";
$Pass = "password";
$Database = "mydb";
$this->conn = new PDO("sqlsrv:Server=$Server;Database=$Database", $User, $Pass);
$this->conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);//allow for SQL query errors
}
catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}

Check using phpinfo() if mssql extension is loaded. According to PHP Manual:
This extension is not available anymore on Windows with PHP 5.3 or later.
If you find out mssql is unloaded, try to connect using sqlsrv extension. Here you can find a few examples http://php.net/manual/ru/function.sqlsrv-connect.php
Anyway it's a good idea to post here an error message you get from PHP.

PHP cannot connect to MS SQL Server 2008 IIS

I did an express install for MS SQL Server 2008 and created a database with a test table. I am running Windows Server 2008 and have IIS, PHP and MS SQL installed. I chose to go with SQL server authentication, where you would need credentials to modify or view the database. I try to print out a simple test table on a web page, but it keeps failing and only returns a white screen..
<?php
$server = "WS1\SQLEXPRESS";
$username = "sa";
$password = "password";
$db = "testdb1";
$dbhandle = mssql_connect($server, $username, $password)
or die ("Cannot connect to SQL Server on $server");
$selected = mssql_select_db($db, $dbhandle)
or die ("Could not open database $db")
echo "You are connected to the " . $db . "database on the " . $server . ".";
$query = "SELECT * FROM table1";
$result = mssql_query($query);
$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";
echo "<li>" . $row[""] . $row[""] . "</li>";
while ($row = mssql_fetch_array($result)) {
print_r($row);
}
mssql_close($dbhandle);
?>
Ah, the horrific white screen. Sometimes very hard to troubleshoot. Often times it's a simple missing semicolon ...
like the one here:
$selected = mssql_select_db($db, $dbhandle)
or die ("Could not open database $db")
Put a semicolon on the end of that statement and you are back in business.

"PHP Fatal error: Call to undefined function mssql_select_db() in c:\...appscript.php on line 16"

Folks, Im trying to run a basic php script in cmd prompt which connects to sql server 2012 on my local machine, its gives me the following error..."PHP Fatal error: Call to undefined function mssql_select_db() in c:...appscript.php on line 16"
Here is my script, im not very familiar with php but have been playing around with it and im unsure if my script is correct..
<?php
$Server = "";
$User = "";
$Pass = "";
$DB = "";
//$SQLKEY = "";
//connection to the database
//$dbconn = sqlsrv_connect($Server, $User, $Pass)
$connectionInfo = array("UID" => $User, "PWD" => $Pass, "Database" => $DB);
$conn = sqlsrv_connect( $Server, $connectionInfo);
//or die("Couldn't connect to SQL Server on $Server");
//select a database to work with
$selected = mssql_select_db($DB, $connectionInfo)
or die("Couldn't open database $myDB");
//declare the SQL statement that will query the database
$query = "SELECT name from test ";
//execute the SQL query and return records
$result = mssql_query($query);
$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";
//display the results
while($row = mssql_fetch_array($result))
{
echo "<br>" . $row["name"];
}
//close the connection
mssql_close($dbconn);
?>
Be great if someone could help or least give me a few pointers.
It seems you are using wrong functions. You should use only functions from http://www.php.net/manual/en/function.sqlsrv-begin-transaction.php
It seems there is no need to select db (there is no sqlserv_select_db function).
You should change your mssql_query to sqlsrv_query and the same for other functions and you should look at PHP manual because some functions may missing.
You need to enable the MSSQL extension.

Trying to connect database MySQL from PHP (Not Successful)

I'm following a tutorial on the net on PHP and MySQL.
I'm using Linux. I'm trying to establish a connection to a database but it is not working.
I have my database:
create database test;
create table user(name text, pass text);
insert into user values('john', '123');
and then my php:
<?php
$_host = "localhost";
$_dbuser = "root"
$_dbpass = "";
$_dbname = "test";
#mysql_connect("$_host", "$_dbuser", "$_dbpass") or die("could not connect");
#mysql_select_db("$_dbname") or die("no database");
echo "connection stablished";
?>
And the output of my file is just a blank tab on the browser.
What should I do to solve this? What am I doing wrong?
Thank you in advance. I'm very new to web programming.
$_host = "localhost";
$_dbuser = "root"
$_dbpass = "";
$_dbname = "test";
$link = mysqli_connect($_host, $_dbuser, $_dbpass, $_dbname);
if (!$link) {
die('Connect Error (' . mysqli_connect_errno() . ') '
. mysqli_connect_error());
}
echo "connection stablished";
Now...
Use mysqli_* functions as mysql_* are deprecated.
You will need $link variable later for queries.
As you're newbie read this: How can I prevent SQL injection in PHP?
Prepared statements FTW! Remember!

Php MSSQL(2012) giving error:Couldn’t connect to SQL Server

I am trying to fetch a set of fields from a Database on MSSQL Database on SQL Server 2012. This is a remote server and I am trying the following piece of code.
//MSSQL Server for retrieving the Member name from Member ID:
//mssql.secure_connection = On
// Need to upload ntwdblib.dll from net
$myServer = "IPAddress/SQLExpress "; // host/instance_name
$myUser = "ID"; // username
$myPass = "pass"; // paasword
$myDB = "dbname"; // database name
// connection to the database
$dbhandle = mssql_connect($myServer, $myUser,$myPass)
or die("Couldn’t connect to SQL Server on $myServer"). mssql_get_last_message();
// select a database to work with
$selected = mssql_select_db("sportsclub", $dbhandle)
or die("Couldn’t open database $myDB");
echo "You are connected to the " . $myDB . " database on the " . $myServer . ".";
$query = "SELECT first_name, last_name";
$query .= "FROM members ";
$query .= "WHERE member_id='".$row['member_id']."'";
// your database query
$result = mssql_query($query);
while($row = mssql_fetch_assoc($result))
{
echo "<td>" . $rows["first_name"] . $rows["last_name"] . "</td>";
}
// close the connection
mssql_close($dbhandle);
//Ended MSSQL Connection
It simply does not connect to the sql server. It gives the error: Couldn’t connect to SQL Server on IPAddress/SQLExpress
I tried checking all configurations like TCP/IP through SQL Server Config management.
Can someone please help?
Ensure remote connections over named pipes are enabled and make sure you're using a backslash before the instance name:
$myServer = "IPAddress\SQLExpress ";
If you'd like to enable connection over the default port (1433) this answer will help.

WebMatrix PHP mySQL

I am using WebMatrix Beta 3 which has support for php 5.2 and 5.3 I am able to run php pages but when I am trying to connect to mySql DB its not working.

$database = 'test';
$link = mysql_connect($hostname, $username, $password)
or die("Could not connect : " . mysql_error());
mysql_select_db($database) or die("Could not select database");
//Below function added to allow customized unescaping.
function mysql_unescape($sRet_VAL=""){
$sRet_VAL = str_replace('\"','"',$sRet_VAL);
$sRet_VAL = str_replace("\'","'",$sRet_VAL);
return $sRet_VAL;
}
?>
and I am using this file as follows
<?php
require_once( $_SERVER['DOCUMENT_ROOT'] . '/config/dbinfo.php');
