This is a bug in MySQL extension.
The mysql_fetch_assoc() function is supposed to take
only one argument. And you found this bug by passing
the $dblink variable which holds (after running opendir)
number 2 as value. The actual bug is in php_mysql_fetch_hash() function (in
php_mysql.c) as there
should be a check for the second possible argument, that it's one of MYSQL_ASSOC,
MYSQL_NUM or MYSQL_BOTH.

<?php
// If the opendir call is before the connect, an associative array
// is NOT returned from mysql_fetch_assoc() - the closedir does not
// seem to have any effect on this phenomena.
//
// It does NOT matter if the code is contained within the if() or
// not. If the opendir() call occurs before the mysql_connect()
// call, I get a farkled array from mysql_fetch_assoc().
//
// Changing the database and/or tables queried does not seem to
// make a difference to the bug.
// Change the 0 to 1 below to see this bug
if (1) {
$bizarrevar = opendir("/etc/");
closedir($bizarrevar);
unset($bizarrevar);
}
$dblink = mysql_connect("localhost","user","password");
mysql_select_db("dbname", $dblink);
$qresult = mysql_query("SELECT * FROM comment", $dblink);
while ($rx = mysql_fetch_assoc($qresult, $dblink)) {
while (list($k,$v) = each($rx)) {
print(" $k = $v<BR>n");
}
