从远程Web服务器连接到本地数据库

I am trying to connect to my local Database from the webserver but i get

Fatal error: Call to undefined function odbc_connect() 
             in -/-/-/7001238/web/s/sage2.php on line 15"

Any help on how to fix issue.

Here is the code i used to connect.

 $odbc['dsn'] = "Sage50";
 $odbc['user'] = "Peach";
 $odbc['pass'] = "XXXX";
 $mysql['host'] = "localhost";
 $mysql['user'] = "root";
 $mysql['pass'] = "";
 $mysql['dbname'] = "sagetest";
 $mysql['idfield'] = "id";
 $debug=true;
 // Step 1: Connect to the source ODBC and target mysql database
 if ($debug) echo "Connect to " . $odbc['dsn'] . ' as ' . $odbc['user'] . "
";
 $conn = odbc_connect($odbc['dsn'], $odbc['user'], $odbc['pass']);
 if (!$conn) {
    die("Error connecting to the ODBC database: " . odbc_errormsg());
 }
 $myconn = mysql_connect($mysql['host'], $mysql['user'], $mysql['pass']);
 if (!$myconn)
    die("Error connecting to the MySQL database: " . $mysql_error());
 if (!mysql_select_db($mysql['dbname'], $myconn))  die("Error selecting the database: " . mysql_error());
// Step 1.5: loop through each table with steps 2-7
$allTables = odbc_tables($conn);
$tablesArray = array();
while (odbc_fetch_row($allTables)) {
   if (odbc_result($allTables, "TABLE_TYPE") == "TABLE") {
      $tablesArray[] = odbc_result($allTables, "TABLE_NAME");
   }
}

Thank you for your time!
