Bug description: mysqli_more_results does not play well with
mysqli_multi_query()
Description:
------------
mysqli_more_results() will always return false after
mysqli_multi_query() for both SELECT and non SELECT queries
Therefore I can not use the loop while (mysqli_more_results()) in
combination with mysqli_next_result() to iterate through result sets
produced by SELECT queries
mysqli_multi_query($conn, $query);
while (mysqli_more_results($conn))
{
mysqli_next_result($query);
/* store first result set */
if ($result = mysqli_store_result($conn)) {
}
}
Code example in http://php.net/manual/en/mysqli.multi-query.php is
outdated because it causes E_STRICT in PHP 5.3.1. It requires
mysqli_more_results() to be called before mysqli_next_result()
There is a workaround
if (mysqli_multi_query($link, $query)) {
do {
/* store first result set */
if ($result = mysqli_store_result($link)) {
while ($row = mysqli_fetch_row($result)) {
printf("%s\n", $row[0]);
}
mysqli_free_result($result);
}
// print divider => will never work
if (mysqli_more_results($link)) {
printf("-----------------\n");
}
} while (mysqli_more_results($link) && mysqli_next_result($link));
}
but mysqli_more_results() seems to do nothing related to result sets
here
Reproduce code:
---------------
<?php
$link = mysqli_connect("localhost", "root", "123456", "test");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT 1";
/* execute multi query */
if (mysqli_multi_query($link, $query)) {
var_dump(mysqli_more_results($link));
}
/* close connection */
mysqli_close($link);
?>
Expected result:
----------------
bool(true)
Actual result:
--------------
bool(false)
