User Update by: btanner@home.net
Status: Open
Bug Type: Scripting Engine problem
Operating system: Win32 (Win 2k)
PHP Version: 4.0.6
Description: Unserialize dies with Apache Module but is FINE with CGI
After changing all my reads and writes to forced binary reads and right, all is well with Win32
Apache module.
IMHO, this is still a bug. If the behaviour is this for the module, it should also be the same for
the CGI.
Why did this work?

Bingo.. got it down to a reasonable amount of code.
I'll provide the code here (its still 65 lines). I have kept the "save" method,
although it is not used in this example. Reason being is that I am loading an object that I
previously saved, so its possible that the save method is the offender.
Here you go. I'll also reply to this message in php-dev (if the list ever starts working) --
with the datafile attached.
--Code starts--
<?
class Module_Variable{
var $Type;
var $Name;
var $Value;
function Module_Variable($Name,$Value,$Type="S"){
$this->Name=$Name;
$this->Value=$Value;
$this->Type=$Type;
}
} //end of module_variable class
class Module {
var $Variables; // Array of Configuration Variables for this Module
var $Inclusions; // Array of Inclusions in case of newuser,deleteuser,etc,etc
var $Path; // Path from Root to get to this module
var $Name;
var $Loaded; // Has this module been loaded, or not?
function Module($Name,$Path){
$this->Name=$Name;
$this->Path=$Path;
$this->Loaded=0;
$this->Variables="";
}
function Save(){
$ModCode=serialize($this);
$FileLocation=__DATAPATH."mod_data/".$this->Name.".mod";
$FilePointer=fopen($FileLocation,"w");
$WriteCheck=fwrite($FilePointer,$ModCode);
if(!$WriteCheck)
die("Error writing output...");
fclose($FilePointer);
}
function Load(){
$FileLocation=$this->Name.".mod";
$FilePointer=@fopen($FileLocation,"r");
if(!$FilePointer)
$this->HandleError($FileLocation);
$EncodedString=fread($FilePointer,filesize($FileLocation));
fclose($FilePointer);
$VarObject=unserialize($EncodedString);
$this->Variables=$VarObject->Variables;
$this->Loaded=1;
}
}//end the class
$MyModule=new Module("login","");
$MyModule->Load();
print("<hr><Br>Good so far");
?>

Please include a short example of both script and the class
you get this with.

I've been running fine on CGI for a while now, jumping between 4.04, 4.07-dev, 4.05
When I tried to switch from 4.05 CGI to 4.05 4.05-Apache ... one of my files does not unserialize
properly. The error message is:
Warning: unserialize() failed at offset 487 of 2797 bytes in c:program filesapache
groupapachehtdocsgt2librariesclassesmodule.class on line 189
If you guys know something about this, please let me know, as soon as possible. In the mean time, I
am going to make a script that saves a serialized object to disk. I will save it to a file using
CGI and then Apache modules. Then, I will try to load em both using Apache and CGI modules... see
what turns up.
