PHP version: 4.3.7
PHP Bug Type: MSSQL related
Bug description: A SELECT statement returns instead of an empty value, a value
containing space
Description:
------------
A SELECT statement returns instead of an empty value for a varchar field,
a value containing a single space. Therefore using the empty() directive
will not work anymore.
Problem only happens with php_mssql.dll from year 2004 for PHP version
4.3.7 and 5.0.0. Using a previous dll from 3/13/03 (4.3.2-RC1) for
instance solves the problem ... but might cause others.
Reproduce code:
---------------
<?php
$db_host = 'localhost';
$db_user = 'sa';
$db_pass = '';
if ($dbh = mssql_connect($db_host, $db_user, $db_pass)) {
print ('<br><br>DB: "'.$db_name.'" connected');
} else {
print ("<br>DB NOK ");
exit;
}
$query = 'SELECT * FROM mydb WHERE id = 1';
$result = mssql_query($query, $dbh);
{
if ($row = mssql_fetch_array($result, MSSQL_ASSOC)) {
print_r($row);
print("\n<br>(" . $row['id'] . ')');
}
}
?>
Expected result:
----------------
...
()
Actual result:
--------------
...
