Ilia,
this is probably what you meant in the first place, but I'll elaborate
a little more:
MS SQL support on Win32 is implemented using the DbLib C API by
Microsoft, which has this limitation. Use TEXT fields instead.

Don't think so ...
He's using Microsoft SQL Server, which has VARCHAR fields of up to 8000
characters (or bytes, not sure)
I'll have a look at this ...

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions.
Thank you for your interest in PHP.
You're dealing with VARCHAR maximum length limitation of 255
characters. This is not a PHP bug.

Description:
------------
Then I try to read value of VARCHAR field I get only 255 characters,
but VARCHAR is 8000 bytes long.
MSSQL v. 7.0
ntwdblib.dll v. 2000.80.194.0
PHP v. 4.3.2
Apache v. 2.0.43 / IIS 6
Reproduce code:
---------------
$myVar = str_repeat("*", 500);
mssql_query("DELETE FROM myTable");
mssql_query("INSERT INTO myTable (myField) VALUES ('".$myVar."')");
$query = "SELECT LEN(myField), myField FROM myTable";
list($realLength, $myVar) = mssql_fetch_row(mssql_query($query));
echo "DB length: ".$realLength."; PHP length: ".strlen($myVar);
Expected result:
----------------
$myVar must be equal $realLength
Actual result:
--------------
strlen($myVar) == 255 (always)
