MSSQL DATABASE CONNECTION WITH PHP - php

Question

Please i am trying to connect to an mssql database on a different machine. Below is my code but i just keep getting a blank page.
I dont know what the issue may be. i have installed php and the mssql drivers.
<?php
$uid = "******";
$pwd = "***\$\$****";
$DB = "***********";
$serverName = "192.***.**.***";
$connectionInfo = array("UID" => $uid, "PWD" => $pwd, "Database"=> $DB, "ReturnDatesAsStrings" => true);
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>

Answer 1

I would suggest that you display the connection error using sqlsrv_errors().
Load the PHP drivers in php.ini file and restart the server.
extension=php_pdo_sqlsrv_54_ts.dll
extension=php_sqlsrv_54_ts.dll
Please see the following example:
<?php
$serverName = "serverName\sqlexpress"; //serverName\instanceName
// Since UID and PWD are not specified in the $connectionInfo array,
// The connection will be attempted using Windows Authentication.
$connectionInfo = array( "Database"=>"dbName");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>

This is for Server 2019 and PHP 7.4.
Download SQLSRV 5.8.0 Drivers here
Have this in your php.ini: (depending on hardware 32 vs 64)
extension=pdo_sqlsrv_74_ts_x64
extension=sqlsrv_74_ts_x64
Use this to create a mssql connection:
Function connect_db() {
$this->connectionInfo = Array("UID" => DB_USER, "PWD" => DB_PASSWORD, "Database" => DB_NAME);
$this->conn = SQLSRV_CONNECT(DB_SERVER, $this->connectionInfo);
if ($this->conn){ return; }
else {echo "Error";die( print_r( sqlsrv_errors(), true ));}
}
