Bug description: Array Memory Allocation Error With register_globals set to "On"
Description:
------------
We fixed this bug by setting Register_Globals to "Off", but we were also
making other changes on the server to solve it, so that might not have
been the fix.
We are using the following code to store database entries in memory for
use later on in the page
When allocating memory for an array dynamically using a sql_query the
values came out as strings, rather than arrays.
I took all of the error checking out of the code below to make it more
clear. We use this code to dump an array to a select menu creation
function.
It should be noted that this bug doesn't always appear, but seems to be
produced for larger arrays (10 - 25) rather than arrays containing 2 or 3
entries.
It should also be noted that adding the statement "$ArrayVariable =
array()" before the following code also solves the problem.
Reproduce code:
---------------
$rslt = mysql_query("SQL....")
$i = 0;
while ($row = mysql_fetch_array($rslt)) {
$ArrayVariable[$i]['Value'] = $row['SQL_Text Value'];
$ArrayVariable[$i]['Label'] = $row['SQL_Text Label'];
$i++;
}
print_r($ArrayVariable);
Expected result:
----------------
Array
(
[0] => Array
(
[Value] => 145
[Label] => Adair, Kris
)
[1] => Array
(
[Value] => 20
[Label] => Bailey, Wayne
)
[2] => Array
(
[Value] => 22
[Label] => Bartos, Alan
)
[3] => Array
(
[Value] => 24
[Label] => Beatty, Marsha
)
)
Actual result:
--------------
Array
(
[0] => 1A
[1] => 2B
[2] => 2B
[3] => 2B
)
