New Comment:

Actually, I have error_reporting set to E_ALL, no error suppression
operators, all variables carefully initialized. I get the error on
occasion on one server, not on others. In a very simple situation, I
get the same error on code like this

$var['idx'] = '';
$var['idx'] .= "more string";

Others who have had the error seem to have had goodluck fixing it
simply by changing to

$var['idx'] = $var['idx'] . "more string";

which should change nothing.

You have some problem in your script. Get rid of '@' and set
error_reporting(E_ALL); and you'll most likely find out what is wrong.
There is no bug here, this is expected behaviour.

Description:
------------


$USER['TEMP'] .= "!";

When I run this some servers (Programmed on Redhat Linux 9 with PHP
4.3.3 and it works fine, tested on another Linux server using PHP 4.3.3
and it returns the error) it returns the following error message:

Fatal error: Cannot use assign-op operators with overloaded objects
nor
string offsets in
(FILE PATH) on line (LINE NUMBER)

I have asked many different programmers about it and nobody has an
answer as to why it causes an error on code that is correct. According
to PHP do***entation the syntax of it is correct.

Another person who has had this problem has do***ented it here:
http://www.faqchest.com/prgm/php-l/php-02/php-0205/php-020581/php02052416_25320.html.
I distribute the script for free and I have had at least 4 different
users report that they are having this problem.

The variable $USER['TEMP'] has been defined before and is not null.

Reproduce code:
---------------
$q = DoQuery("SELECT * FROM $SERVER[TBL_PREFIX]users WHERE
username='$USER[NAME]'");
$USER['TEMP'] = $row[13];
$k = 1; $i = 0; $s = 0; $r[0] = "";
$USER['TEMP'] .= "!";
while($k){
$sub = substr($USER['TEMP'],$i,1);
if($sub == "!"){
$k = 0;
break;
}
if($sub == ","){
$s++;
}else{
@$r[$s] .= $sub;
}
$i++;
}

Expected result:
----------------
I would expect it to add "!" to $USER['TEMP'] every time it goes
through the while loop, on some servers it does but on others it
returns the error even if they are the same type of server running the
same version of PHP.

Actual result:
--------------
On some servers it works correctly and on others it says:

Fatal error: Cannot use assign-op operators with overloaded objects
nor
string offsets in
(FILE PATH) on line (LINE NUMBER)
