Submitted: 2005-09-13 13:59 UTC Modified: 2005-09-13 16:06 UTC
From: cd_gk at gmx dot de Assigned:
Status: Closed Package: MySQLi related
PHP Version: 5.0.5 OS: Red Hat Enterprise Linux
Private report: No CVE-ID: None
 [2005-09-13 13:59 UTC] cd_gk at gmx dot de
Description:
------------
AMD Opteron x86_64 GNU/Linux

Apache/1.3.33 (Unix) PHP/5.0.4 or PHP/5.0.5

call mysqli_fetch_array with an resulttype craches.
without resulttype works fine.

Reproduce code:
---------------
<?php
$link = mysqli_connect("localhost", "user", "password", "database");

$query = "SELECT * FROM table";
$result = mysqli_query($link, $query);

$row = mysqli_fetch_array($result, MYSQLI_BOTH); # failed
printf ("1. %s (%s)\n", $row[0], $row['name']);

#$row = mysqli_fetch_array($result, MYSQLI_NUM); # failed
#printf ("2. %s (%s)\n", $row[0], $row[0]);

#$row = mysqli_fetch_array($result, MYSQLI_ASSOC); # failed
#printf ("3. %s (%s)\n", $row[0], $row['name']);

#$row = mysqli_fetch_array($result); # ok
#printf ("4. %s (%s)\n", $row[0], $row[0]);
?> 

Expected result:
----------------
A row like this:

1. 2 (Hello World)


Actual result:
--------------
##[MYSQL_BOTH]
