Log: Fix for Bug #55582 mysqli_num_rows() returns always 0 for unbuffered, when
mysqlnd is used
------------------------------------------------------------------------
[2011-09-05 09:49:29] and...@php.net
Description:
------------
As the description says, there is wrong check in mysqli, which doesn't allow
the mysqlnd code to run. mysqli returns always 0 for num_rows() even if the
whole result set has been read. This bug exists since 5.3.0, which first
bundled mysqli with mysqlnd.
Test script:
---------------
./php -r
'$c=mysqli_connect("127.0.0.1","root","root","test");var_dump($c->real_query("SELECT
1"));var_dump($res=$c->use_result(), mysqli_num_rows($res),
$res->fetch_assoc(), mysqli_num_rows($res), $res->fetch_assoc(),
mysqli_num_rows($res));'
Expected result:
----------------
Warning: mysqli_num_rows(): Function cannot be used with MYSQL_USE_RESULT in
Command line code on line 1
Warning: mysqli_num_rows(): Function cannot be used with MYSQL_USE_RESULT in
Command line code on line 1
object(mysqli_result)#2 (5) {
["current_field"]=>
int(0)
["field_count"]=>
int(1)
["lengths"]=>
array(1) {
[0]=>
int(1)
}
["num_rows"]=>
int(1)
["type"]=>
int(0)
}
int(0)
array(1) {
[1]=>
string(1) "1"
}
int(0)
NULL
int(1) ----- here is the difference
Actual result:
--------------
Warning: mysqli_num_rows(): Function cannot be used with MYSQL_USE_RESULT in
Command line code on line 1
Warning: mysqli_num_rows(): Function cannot be used with MYSQL_USE_RESULT in
Command line code on line 1
object(mysqli_result)#2 (5) {

int(1)
["lengths"]=>
array(1) {

}

["type"]=>

}
int(0)
array(1) {
[1]=>
string(1) "1"
}
int(0)
NULL
int(0) --- should have been 1
