What the?!

In real life, I'm a java programmer for hire, and in my secret life, I'm a beginning PHP enthusiast. I'm working on a piece of code that simply iterates through image files in a directory, creates objects out of them, and then stores them in an array. All very straightforward shit. The one piece of trickery that occurs is that I delegate the creation of the image objects to a factory. However, the factory is not returning the same object I had it create...when I examine the properties on the returned object, the data isn't there... The property values are empty strings, or more specifically, whatever the class had defined as the default value for that property. Furthermore, when I call an accessor method, it's returning me a weird and seemingly random number. I've attached the code and the output below. If anyone has any insight into what I'm doing wrong, please be so kind as to share it! Thanks!



# Code

getImage("$path/$file");
$fullpathmethod = $image->getFullPath();
$fullpathprop = $image->m_fullPath;
/* This line prints, but $fullpath is blank. */
echo "getFullpath() from getDir(): $fullpathmethod", "\r\n";
echo "fullpath property from getDir(): $fullpathprop", "\r\n";
$images[$i] =& $image;
$i++;
}
closedir($dir);
}
else
{
die("Not a valid filename");
}
}

$this->$m_fullPath = $fullPath;
}

function getFileName()

/* This line prints just fine*/
echo "getFullPath from ImageFactory.getImage(): ", $newImage->getFullPath(), "\r\n";
$newImage->setFileName($baseFilename);
$newImage->setTimestamp($timestamp);
return $newImage;
}
else

# return new NullImage();

function parseTimestamp($baseFilename)
{
$day = substr($baseFilename, 0, 2);
