Built with:  
(edited config template to remove uneccessary sybase libs that are not included with freetds -lsybtcl -lcomn -lcs )

./configure --prefix=/home/username/php --with-sybase-ct=../../freetds --with-pgsql=/home/postgres/pgsql --with-apache=../../apache_1.3.22 -enable-track-vars --with-imap=../../imap
make
make install

FreeTDS verified functional using test scripts, and functional through Perl to same DB that PHP is connected to.

Problem: Text type returns only first 255 chars
Expected: >540 chars  (can retrieve through FreeTDS/Perl)

php.ini contains uncommented lines:
mssql.textlimit=8192
mssql.textsize=8192

Query to MSSQL Server:
SELECT @@TEXTSIZE
Returns: 4096
Expected: 8192  (due to php.ini settings?)

Query to MSSQL Server:
SET TEXTSIZE 8192 SELECT @@TEXTSIZE
Returns: 8192
Expected: 8192

Suspect: php.ini not being read
But: other setting changes show up on php_info()
Suspect: mssql settings not being read properly from
         php.info?

Query to MSSQL Server:
SET TEXTSIZE 8192 SELECT our_col FROM our_table;
Returns: only first 255 chars of our_col 
Expected: all 500+ chars in field

When you use subase-ct and FreeTDS you are not using the mssql extension, and all the settings in the ini file for mssql is not used.

The settings you are refering to works when you use the mssql extension, though that extension is only available on Win32 platforms.

Then there still exists a problem with the sybase-ct support for mssql, in that there is no way to specify a TEXTSIZE that allows PHP to support MSSQL 7.0's TEXT type.
Is there not?

I have 4.1.2 and It's still not fixed.

Running my .php  that has a query "SELECT sometexttypefield FROM sometable"; with /usr/bin/php4 results in ;FATAL:  emalloc():  Unable to allocate -2147483648 bytes.

So it's definately some a bug and it probably can be solved if we know where this mailloc is called.

As of version 4.2.1, this issue has still not been corrected. Perhaps the problem lies with FreeTDS.
Apparently neither the CT-Lib and DB-Lib for Sybase have no use for this property (MSSQL TEXT SIZE).

If you must connect to MS SQL Server from PHP, I would suggest creating an include file that is included at the top of any PHP script that needs to access the MS SQL Server. Let the include file open a connection and call a query to "set textsize 65536" or to whatever limit you want.

e.g.

<?php

// include file for MS SQL server

$HOSTNAME = "SQLServer70";
$USERNAME = "sa";
$PASSWORD = "??";

$conn = mssql_pconnect($HOSTNAME, $USERNAME, $PASSWORD);

if ($conn) {
  mssql_query("SET TEXTSIZE 65536");
  mssql_select_db("whatever", $conn);
}

?>

Make sure you set TDS Version to 7 or 8. You can do this in freetds.conf where you define your server connection.
