PHP stdClass

[tbirnseth]

I have a large class. The $this internal variable seems to be getting clobbered somewhere. On one line an echo "this->id=$this->id" works perfectly. The next line is a conditional statement and if that 'echo' line is inserted there it tells me that 'id' is an unknown property. Example:

$foo = 'bar';
echo "this->id=$this->id";  // works greate shows 'this->id=36'
if( isset($foo) ) {
  echo "this->id=$this->id";  // fails with unknown property 'id'
}

If I do a print_r of the object, I clearly see [id] = 36 listed. But I noticed at the end of the object there is an additional entry for stdClass of:

this:stdClass Object
(
    [invSupplierKeys] => Array
        (
            [1] => 30011
        )
}

I do not do a new stdClass anywhere. Where and how can this be being created and why is it in the context of $this?

Hope someone can shed some light....

This worked fine for me:

<?php
class Test
{
   var $id = 36;
   function Test()
   {
      echo "this->id=$this->id";
      echo "<br>";
      if(true)
      {
         echo "this->id=$this->id";
      }
   }
}
$test = new Test();

So, if you are still having a problem, we probably need to see the exact code you are using that results in this error (preferably reduced to the shortest, simplest code you can find that generates the error).

That's the problem, it's a BIG class and I don't know how to reproduce it. This class (emailClass) extends a docTemplate class which in turn utilizes a varInfo class which uses several classes (orderClass, orderItemClass, itemOptionClass, inventoryClass, invSupplierClass, etc....)

This just came up and I'm not sure why. I've had lots of run time on all of this without problems. All I know is that if I put the debugging output on one line (ahead of an if( isset(...) )) it's fine, but if I put it below the if() it fails...

Makes absolutely no sense to me... Note that most all of the classes utilize a globalObjectClass which returns a reference to a common object. I.e. I do
$Aobj =& newGlobalObject("Aclass.php"); and then maybe in a different function I do the same thing. It allows me to keep the class context rather than having separate instances of those classes.
