-Summary: @unserialize() throws E_NOTICE with custom handler
Reported By: lsole at maresme dot net
Status: Open
Bug Type: Output Control
Operating System: FreeBSD
PHP Version: 4.3.4
New Comment:
I think I've misunderstood what the error control operator was sending
to my custom error handling. I thought it was sending a zero error code
but what it does is to set error_reporting() to zero. Sorry!
Anyway, I wonder if it is not a bug that unserialize() throws an
E_NOTICE error if the input is not unserializable. The function
description says it should return FALSE but says nothing about throwing
errors. As an example, base64_decode() does not throw errors if the
input can't be decoded.

Description:
------------
@unserialize() throws E_NOTICE with custom handler
Reproduce code:
---------------
<?php
function myErrorHandler($errno, $errmsg, $filename, $linenum) {
if ($errno == 0) return;
$error_type = array(0 => 'No Error', 8 => 'Notice'); // just the ones
we need...
echo '<b>' . $error_type[$errno] . '</b>: ' . $errmsg . ' in <b>' .
$filename . '</b> on line <b>' . $linenum . '</b><br>' . chr(10);
}
$a = 'abc123';
error_reporting(E_ALL);
$b = unserialize($a); // throws error because $a is not unserializable
if ($b === false) {echo 'failed!<br>';} else {echo $b . '<br>';}
$b = @unserialize($a); // @ suppresses error
if ($b === false) {echo 'failed!<br>';} else {echo $b . '<br>';}
set_error_handler('myErrorHandler');
$b = unserialize($a); // throws error because $a is not unserializable
if ($b === false) {echo 'failed!<br>';} else {echo $b . '<br>';}
$b = @unserialize($a); // should throw nothing but throws Notice!
if ($b === false) {echo 'failed!<br>';} else {echo $b . '<br>';}
?>
Expected result:
----------------
E_NOTICE errors should not happen when prepending @: the custom handler
should receive $errno = 0
Actual result:
--------------
E_NOTICE error
