I really don't know why these functions are not deprecated yet. There isn't even a built-in way to escape your values, let alone use parameterized queries.

On Windows servers, you should use SqlSrv (http://php.net/sqlsrv), an alternative driver for MS SQL is available from Microsoft: ? http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

On Linux servers, you should use PDO_DBLIB (http://php.net/pdo-dblib).

I made this wrapper a few years ago to handle mssql -> sqlsrv_pdo migrations. It's a drop-in include that provides the mssql_ functions using a sqlsrv_pdo implementation.

Here is version 3.0 of the MSSQL PHP driver.
1.1 is severely deprecated.

Using the new MS driver I have come across a difference between the array that I get back compared to mssql.

Example is here (both return types are associative arrays:

sqlsrv_fetch_array($resource, SQLSRV_FETCH_ASSOC)
"same as" sqlsrv_fetch($resource), as this returns by default an associative array, by default sqlsrv_fetch_array returns both an associative and a numeric array.

returns...

array(6) { ["yaxis"]=> object(DateTime)#58 (3) { ["date"]=> string(19) "2010-09-29 00:00:00" ["timezone_type"]=> int(3) ["timezone"]=> string(19) "Australia/Melbourne" } ["xaxis"]=> string(7) "Inbound" ["tt"]=> int(280345) ["ht"]=> int(297219) ["wt"]=> int(16874) ["calls"]=> int(1539) } string(8) ""

mssql_fetch_assoc($resource)

returns

array(6) { ["yaxis"]=> string(19) "2010-09-29 00:00:00" ["xaxis"]=> string(7) "Inbound" ["tt"]=> int(280345) ["ht"]=> int(297219) ["wt"]=> int(16874) ["calls"]=> int(1539) } string(8) ""

it would be much too difficult to change a large number of applications to compensate for this.

Found my answer...
add this to your connection objects parameters on instantiation

"ReturnDatesAsStrings"=>true

Found it buried in this article: http://msdn.microsoft.com/en-us/library/ee376928(SQL.90).aspx

this function get inserted ident like function mysql_insert_id()

<?php function mssql_insert_id() { $id = 0; $res = mssql_query("SELECT @@identity AS id"); if ($row = mysql_fetch_array($res, MYSQL_ASSOC)) { $id = $row["id"]; } return $id; } ?>

As of October 2009, the new name is "SQL Server Driver for PHP 1.1"

Go to Microsoft Download Center http://www.microsoft.com/downloads and search
for "SQL Server Driver for PHP" which should take you to the following link:

http://www.microsoft.com/downloads/details.aspx?displaylang=en
&FamilyID=ccdf728b-1ea0-48a8-a84a-5052214caad9

But I wouldn't trust it to stay there. Microsoft has been moving a lot of download links lately.

i struggled with sqlsrv_connect for some time, first i had to get native client 2008 to get it to work, 2005 was not enough.

then i got som note that dll was compiled with wrong version, so i had to use test version 1.1 istead of 1.0 of the client and pick the version called php_sqlsrv_53_ts_vc6.dll

but still no success with connect.

finally i spent 7 hours testing things before i found out:

$serverName = "(local)"; ERROR for me

$serverName = "localhost\myinstansofdatabase"; //WOHOOOO

Microsoft has issued in nearly past Native SQL driver for PHP.
This driver works with MSSQL 2000, 2005 and 2008 servers. Driver is issued as PHP extension. Source codes also available.

The driver supports native conversion to UTF-8, scrollable cursors and other features which this (old) library does not.

For more information and extension download please see
http://www.codeplex.com/SQLSRVPHP
They have also blog on http://blogs.msdn.com/sqlphp/

Im running PHP 5.3 and used the php development ini and when I use the Microsoft SQL for PHP driver, I get the following error:

[15-Aug-2009 07:48:13] PHP Warning: PHP Startup: sqlsrv: Unable to initialize module

Hi, i was need some short and simple script to list all tables and columns of MSSQL database. There was nothing easy to explain on the net, so i've decided to share my short script, i hope it will help.

<?php $all = MSSQL_Query("select TABLE_NAME, COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS order by TABLE_NAME, ORDINAL_POSITION"); $tables = array(); $columns = array(); while($fet_tbl = MSSQL_Fetch_Assoc($all)) { // PUSH ALL TABLES AND COLUMNS INTO THE ARRAY $tables[] = $fet_tbl[TABLE_NAME]; $columns[] = $fet_tbl[COLUMN_NAME]; } $sltml = array_count_values($tables); // HOW MANY COLUMNS ARE IN THE TABLE foreach($sltml as $table_name => $id) { echo "<h2>". $table_name ." (". $id .")</h2><ol>"; for($i = 0; $i <= $id-1; $i++) { echo "<li>". $columns[$i] ."</li>"; } echo"</ol>"; } ?>

After extensive research trying to get PHP on Linux communicating with SQL Server 2005 and 2008 including support for all Unicode, MAX and XML data types I could not find any open source solutions...yes, I spent a lot of time trying to get FreeTDS to work to no avail.

I found one free solution that runs on Windows which is to use the "SQL Server Driver for PHP" provided by Microsoft (http://sql2k5php.codeplex.com). The driver relies on the Microsoft Native Client ODBC drivers for SQL Server 2008 (part of the "Microsoft SQL Server 2008 Native Client" which is downloadable from Microsoft) which is why this solution will not work on anything except Windows.

I did find a solution that works for PHP on Linux but it's not free...use the standard PHP::ODBC lib (free) and the Easysoft ODBC driver for SQL Server (not free, but reasonable by Enterprise standards). You can check out the ODBC driver by going here http://www.easysoft.com/products/data_access and looking for "Easysoft ODBC-SQL Server Driver"

I got a serious problem with Unicode data when working with PHP and MSSQL. I have to say the PHP and MSSQL doesn't seem to be a good combination.

MSSQL is really complicated to work with since the whole server uses a single character encoding[ucs-2]. In order to store unicode information, the column data types must be specified as one of the national character types, NVARCHAR, NCHAR or NTEXT.

In order to retrieve data saved in unicode format, M$ suggest users to cast columns to binary data.Unfortunately php_mssql extension doesn't support binary data to be returned in string columns.

My advice is to use FreeTDS driver [it's just an php extension]. This driver seems to handle unicode data better. I can put and receive unicode with casting or change encoding.

A good tutorial "Using freeTDS" can be found here

http://docs.moodle.org/en/Installing_MSSQL_for_PHP

However, freeTDS is not a perfect solution for unicode data. I'm not able to execute stored procedures with mssql_bind, mssql_bind without having my text changed.

On windows, do not use this for mssql 2005 of later. The methods of access are deprecated.

Use the Microsoft SQL Server 2005 Driver for PHP instead.
Current link is.
