The main part of php's upgrade is to

..addresses a serious memory corruption problem within PHP concerning references. If references were used in a wrong way, PHP would often create memory corruptions which would not always surface and be visible.

Looking at the problems it refers to these functions :
| Quote: |
function &db_rowarr($result)
{
return mysql_fetch_row($result);
}
function &db_saq($q)
{
return mysql_fetch_row(q($q));
}
function &db_sab($q)
{
return mysql_fetch_object(q($q));
}

There is a php bug report on this issue here.
So the scope of what is returned by mysql_fetch_row / _object ends when the function ends. To my understanding then one way around this is to create a new variable in GLOBAL.php and edit the functions like so :
| Quote: |
./FUDforum/include/GLOBALS.php
$reference_result = "";
./FUDforum/include/theme/default/db.inc
function &db_rowarr($result)
{
$reference_result = mysql_fetch_row($result);
return $reference_result;
}
function &db_saq($q)
{
$reference_result = mysql_fetch_row(q($q));
return $reference_result;
}
function &db_sab($q)
{
$reference_result = mysql_fetchobject(q($q));
return $reference_result;
}
