Bug Type: Documentation problem
Operating System: Linux RH 7.2
PHP Version: 4.2.0
New Comment:
I struggled with the $_SESSION problem for almost a week. When I read
this report, that is when reality hit me. In the comment written by
"[EMAIL PROTECTED]" saying that I'm not suppose to use the numberic value.
I'm using PHP 4.2.1 and AIX 4.3.3. Here's the example that work which
should not have work at all. See the "//This one work!! (Numberic
Value)".
Why do I have to spend almost a week struggling over it? I read many
documentation about $_SESSION vs. session_register() with the
register_global turned off, but they say nothing about the numeric
value that aren't allowed to be used?
Thanks,
FletchSOD

You're not supposed to do that. But it should indeed be documented.

Ok, that seems reasonable. (Even though I cannot find anything in the
manual that explicitly states that numerical indexes are unsupported)
However, the setting of a numerical index seems to silently break
something, since the other values in the example are affected as well.
Is this really the intended behavior?

Numerical indexes in $_SESSION are NOT supported.
(and never will be)
User error -> bogus.

what if you try :
<?
session_start();
session_register("foo");
session_register(4);
session_register("a");
session_register("counter");
print "<PRE>";
print "Current values:\n";
print '"foo"=' . $_SESSION["foo"] . "\n";
print '4=' . $_SESSION[4]."\n";
print '"a"=' . $_SESSION["a"]."\n";
$_SESSION["foo"] = "bar";
$_SESSION[4] = "four";
$_SESSION["a"] = "b";
if(!isset($_SESSION["counter"]))
$_SESSION["counter"] = 1;
else
$_SESSION["counter"]++;
print "Count = ".$_SESSION["counter"]."\n";
print "</PRE>";
?>
$_SESSION["foo"] and $_SESSION["counter"] should be working
$_SESSION[4] doesn't (I guess its because of the numerical key) and
$_SESSION["a"] neither (but works if "a" is changed to "ab").

I'm having problems using $_SESSION, it throws away some of my values
between page loads. The following code triggers the problem.
<?
session_start();
print "<PRE>";
print "Current values:\n";
print '"foo"=' . $_SESSION["foo"] . "\n";
print '4=' . $_SESSION[4]."\n";
print '"a"=' . $_SESSION["a"]."\n";
$_SESSION["foo"] = "bar";
$_SESSION[4] = "four";
$_SESSION["a"] = "b";
if(!isset($_SESSION["counter"]))
$_SESSION["counter"] = 1;
else
$_SESSION["counter"]++;
print "Count = ".$_SESSION["counter"]."\n";
print "</PRE>";
?>
The first run, it prints this:
Current values:
"foo"=
4=
"a"=
Count = 1
Which is what is expected, since the values haven't been set yet,
except for the counter.
Now the second run, this is where the problem show up:
Current values:
"foo"=bar
4=
"a"=
Count = 1
This seems to be wrong! The first value has been set, but none of the
others. The counter should have been incremented also. The expected
result of the second run would be
Current values:
"foo"=bar
4=four
"a"=b
Count = 2
