1. DSN einrichten

2. Php.ini anpassen
mssql.secure_connection = ON

3. Beispiel:
<?
$dsn="server01";
$username="sa";
$password="passwort";

$sqlconnect=odbc_connect($dsn,$username,$password);
$sqlquery="SELECT Vorname FROM tbl_Mitarbeiter;";
$process=odbc_exec($sqlconnect, $sqlquery);

while(odbc_fetch_row($process)){
$Vorname = odbc_result($process,"Vorname");
echo "$Vorname<br>"; }
odbc_close($sqlconnect);
?>
