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

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");

Thanks for all your help on this guys.  

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?

binary mode only makes a difference when youstore 
carriage-returns in your file. i bet your "old" test did 
not have CR in the data.

i consider this problem "fixed"
