Status: No Feedback
Bug Type: Arrays related
Operating System: Unix
PHP Version: 4.2.0
New Comment:
Tested with PHP 4.3.1, same problem:
Globalized arrays cannot be sorted using array_multisort, although the
functions returns TRUE!
Another short piece of code to test:
<?
function test() {
global $data;
$data= array("first", "fifth", "second", "forth",
"third");
$sort= array(1,5,2,4,3);
array_multisort($sort, $data);
print_r($data);
}
test();
?>
Without "global $data;" it works fine.

Works fine here with latest CVS head.
Please, try PHP 4.2.3. (4.2.0 is really too old..)

Sorry, try this with and without "global $row;"
<?
function t() {
global $row;
$row =
array(array("1","Php"),array(2,"I"),array(3,"Love"));
foreach ( $row as $value ) {
$sortarray[] = $value[1];
}
array_multisort($sortarray,$row);
print_r($row);
echo "<br>";
print_r($sortarray);
}
t();
?>

Please provide a short (!) complete and self-containing example script.
You should also try with the 4.2.3 release.

Using array_multisort in a function don't work if the array
is "global" (you can paste the following code) :
<HTML>
<HEAD>
<TITLE></TITLE>
</HEAD>
<body>
<?
function t() {
global $row;
$file = fopen("file.txt","r") or die;
while (!feof($file)) {
$row[] = fgetcsv($file,80,";");
}
/* $row[] like this
Array ( [0] => Array ( [0] => 406
[1] => xxxxxxxxxxxxxxxxxxxx
[2] => 5,72 )
[1] => Array ( [0] => 001
[1] => zzzzzzzzzzzzzzzzzzzzz
[2] => 5,77 )
[2] => Array ( [0] => 402
[1] => aaaaaaaaaaaaaaaaaaaaa
[2] => 13,71 )
[3] => Array ( [0] => 009
[1] => fffffffffffffffffffff
[2] => 7,61 )
)
I want to sort it on aaa.../fff.../xxx.../zzz...
*/
fclose($file);
foreach ( $row as $value ) {
$sortarray[] = $value[1];
}
/* $sortarray like this
Array ( [0] => xxxxxxxxxxxxxxxxxxxx
[1] => zzzzzzzzzzzzzzzzzzzz
[2] => aaaaaaaaaaaaaaaaaaaa
[3] => ffffffffffffffffffff
)
*/
// I try to use array_multisort($row,$sortarray); too
array_multisort($sortarray,$row);
print_r($row);
// no change for $row[], until i remove global for $row;
echo "<br>";
print_r($sortarray);
/* $sortarray[], now like this
Array ( [0] => aaaaaaaaaaaaaaaaaaaa
[1] => ffffffffffffffffffff
[2] => xxxxxxxxxxxxxxxxxxxx
[3] => zzzzzzzzzzzzzzzzzzzz
)
or no change if set to global too.
*/
}
t();
?>
</body>
</HTML>
