[!--quoteo(post=363513:date=Apr 10 2006, 08:33 PM:name=heckenschutze)--][div class=\'quotetop\']QUOTE(heckenschutze @ Apr 10 2006, 08:33 PM) [snapback]363513[/snapback][/div][div class=\'quotemain\'][!--quotec--] When your pointing to variables in your class, you shouldn't be including the $ (only for $this->x), since your not initializing the classes with any values, we don't need to call them as "functions". You can also save resources, by creating a reference to the class. WRONG: [code]$this->$imageModifier = new ImageModifier(); $this->$testHelpers = new TestHelpers();[/code] RIGHT: [code]$this->imageModifier = & new ImageModifier; $this->testHelpers = & new TestHelpers;[/code] Fix up the rest of your code and give it a try :) [/quote] Awesome thanks heckenschutze, you actually answered two questions for the price of one :) I was trying to figure out how to do references.

Ok all im having a few problems and for the life of me cant figure this out. Im trying some object oriented php for the first time. Specifically a image manipulation library. At the same time im trying to write it in a test driven fashion. Im calling the function in my class from a function in my test class and getting an error. The weird thing is i have a third class for test utilities and i use that the SAME way and it works. THat said heres the code: ImageModifierTest.php [code] <? include("TestLib.php"); ?> <? include("ImageModifier.php"); ?> <?   class ImageModifierTest //implements ITest   {     var $imageModifier;     function __construct()     {     }     function TestOpenBinaryStream()     {       $streamToSend = "111010001010001";       $this->$imageModifier = new ImageModifier();       $this->$testHelpers = new TestHelpers();       return $this->$imageModifier->OpenBinaryStream($streamToSend);       //return $this->$testHelpers->AssertAreEqual($binaryStream, $streamToSend);     }     function ExecuteTests()     {       $success = $this->TestOpenBinaryStream();       if ($success == true)       {         return "Success";       }       else       {         return "Failure";       }     }   } ?> <?   $imageModifierTests = new ImageModifierTest();   echo $imageModifierTests->ExecuteTests(); ?> [/code] ImageModifier.php [code] <? //include("ITest.php"); ?> <?   class ImageModifier   {     //MEMBERS     var $mImage = "";     var $mModifiedImage = "";     var $mBinaryImageStream = "";     function __construct()     {     }     function SetImageFile($image)     {         $mImage = $image;     }     function OpenBinaryStream($stream)     {       $this->$mImage = $stream;       $this->$mBinaryImageStream = $stream;       return $this->$mImage;     }   } ?> [/code] TestLib.php [code] <? //TEST Helpers class TestHelpers {   function AssertAreEqual($lhs, $rhs)   {     return $lhs == $rhs;   } } ?> [/code] You might notice i have some commented out code in there. I was going to write this with interfaces and a few other features but then found out they are php5 only and im using php4 on my server. The error message i get is : [!--quoteo--][div class=\'quotetop\']QUOTE[/div][div class=\'quotemain\'][!--quotec--] Fatal error: Call to undefined function: openbinarystream() in /home/flyerweb/public_html/imagelibrary/ImageModifierTest.php on line 16 [/quote] [b]Any ideas?[/b] Thanks Note: Seeing how i commented out the AssertEquals above i should let you all know when that is uncommented it works fine. But the one above it doesnt.
