Example #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);

mssql_free_result($query);

### Notes

> Note: Note to Windows Users

> Due to a limitation in the underlying API used by PHP (MS DBLib C API), the length of VARCHAR fields is limited to 255. If you need to store more data, use a TEXT field instead.
