there are same problem with VARBINARY, if you are forced to use existing database with such fields you can do it like this:
SELECT CAST(master.dbo.fn_varbintohexstr(VARBINARYFIELD) AS TEXT) FROM table;
mssql_field_length
(PHP 4, PHP 5, PECL odbtp >= 1.1.1)
mssql_field_length — Get the length of a field
Uyarı
Bu işlev PHP 7.0.0'da tamamen KALDIRILMIŞTIR.

Örnekler
Örnek 1 mssql_field_length() example
<?php
// Connect to MSSQL and select the database
mssql_connect('MANGO\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');
// Send a select query to MSSQL
$query = mssql_query('SELECT [name], [age] FROM [php].[dbo].[persons]');
// Print the field length
echo 'The field \'age\' has a data length of ' . mssql_field_length($query, 1);
// Free the query result
mssql_free_result($query);
?>

The field 'age' has a data length of 4
Notlar
Bilginize: Note to Windows Users
Due to a limitation in the underlying API used by PHP (MS DBLib C API), the length of
VARCHARfields is limited to 255. If you need to store more data, use aTEXTfield instead.
