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);
?>
