Description:
------------
I call two functions, the one after the other. The first one is doing
an output redirection using ob_start(). The second one is just modifying
a variable. It is like the second function is executed just after the
ob_start() without waiting for the end of the first function. The second
function is called on an arbitrary local variable, for which the
serialization becomes inconsistent.
This bug has been found on PHP 5.2.5, but also 5.2.4, on Linux, Windows
XP and Vista.
Reproduce code:
---------------
$Txt = '';
f_Action1($Txt);
f_Action2($Txt);
echo $Txt;
function f_Action1(&$Txt) {
$z = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ';
echo "value before={".$z."} <br>\r\n";
ob_start();
echo "value after={".$z."} <br>\r\n"; // Bug here : it is like
Action2() has been applied to $z
echo "serialize={".serialize($z)."} <br>\r\n"; // Bug here : the
serialization is inconsistent between size and value.
$Txt = ob_get_contents();
ob_end_clean();
}
function f_Action2(&$Txt) {
$Txt = str_replace('ABCDEFGHIJKLMNOPQRSTUVWXYZ','abc',$Txt);
}
Expected result:
----------------
value before={ABCDEFGHIJKLMNOPQRSTUVWXYZ}
value after={ABCDEFGHIJKLMNOPQRSTUVWXYZ}
serialize={s:26:"ABCDEFGHIJKLMNOPQRSTUVWXYZ";}
Actual result:
--------------
value before={ABCDEFGHIJKLMNOPQRSTUVWXYZ}
value after={abc}
serialize={s:26:"abc";}
