PHP 8.1 Count issue
-
I'm testing my old PHP code with PHP 8.1 (code is working fine with PHP 7.4). Following line is not working on PHP 8.1
$total += count($row[0]);
I tried with strlen but it gives totally wrong result because this count is counting messages, size of inbox.
if (!defined("_COMMON_")) {echo "stop";exit;}
include_once($ld_engine_path."inc_connect.php");
$m_result = mysqli_query($conn,"select new_mails from ".$mysql_table_prefix."users where id=$is_regist") or die("database error
".mysqli_error($conn));
if (mysqli_num_rows($m_result))
list($new_board_messages) = mysqli_fetch_array($m_result, MYSQLI_NUM);
if (!isset($new_board_messages)) $new_board_messages = "0";
mysqli_free_result($m_result);$m_result = mysqli_query($conn,"select concat(subject,body) from ".$mysql_table_prefix."board where user_id=$is_regist") or die("database error: cannot retrieve mail-messages
".mysqli_error($conn));
$total = 0;
while ($row = mysqli_fetch_array($m_result, MYSQLI_NUM))
$total += count($row[0]); // This line is not working on PHP 8.1$percentage = round($total / $max_mailbox_size *100);
mysqli_free_result($m_result); -

mysqli_free_result($m_result);You haven't explained what "not working" means. The only notable difference documented in that function between v7 and v8 is:
Prior to PHP 8.0.0, if the parameter was neither an array nor an object that implements the Countable interface, 1 would be returned, unless value was null, in which case 0 would be returned.
So either you're now getting a
TypeErrorwhere previously you were just counting the number of rows; you're now getting the sum of the string lengths, whereas previously you were counting the number of rows; or something else is happening, which you haven't explained.

You are correct, previously it was counting number of rows, now it's counting string lenghths which is not the requirement. Please suggest me a solution
Replace:
$total += count($row[0]);
with:
$total += 1;
