New Comment:
The empty string comes from libmysql, but also mysqlnd doesn't have a
solution as the data is not transfered with the meta-data for the
columns.
A comment in mysqlnd reveals more :
char *def; /* Default value (set by mysql_list_fields) */
mysql_list_fields uses COM_FIELD_LIST, from the C/S protocol. Only in
this case the default value is sent. If you want to get it, you need to
issue SHOW FIELDS FROM or a query against INFORMATION_SCHEMA.

This is very simple function which just wraps around the provided
libmysql function 'mysql_fetch_field' and pretty much can't be a bug on
the PHP side. What mysql version have you compiled PHP with?

Description:
------------
The object returned from MySQLi's fetch_field() does not ever aggregate
the ->def value.
Reproduce code:
---------------
(mysql database table definition)
CREATE TABLE foo (
some_value VARCHAR(50) DEFAULT 'blah'
);
(PHP Code)
<?php
$mysqli = new mysqli("localhost", "root", "", "test");
$query = "SELECT * from foo";
if ($result = $mysqli->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
printf("Default Value: %s\n", $finfo->def);
}
$result->close();
}
/* close connection */
$mysqli->close();
?>
Expected result:
----------------
Default Value: blah
Actual result:
--------------
Default Value:
------------------------------------------------------------------------
