Maybe learn PHP first? AbraCadaver already told you how to solve the problem: Thanks AbraCadaver that did solve this issue...

I changed the variable name to $_this Then I get an error (Fatal error: Call to a member function createUnique() on a non-object in) in this line $new = $this->createImage($width,$height);

I am trying to convert a php4 app to php5 and am getting this error (Fatal error: Cannot re-assign $this in ) when I call this class. $this = $this->createUnique($new); is the line that generates the error. I try to rename $this to $_this but it does not help. I think I lose the reference to the object later on in the code. Then I will get an error like (Fatal error: Call to a member function createUnique() on a non-object in) Is there another way to reference the current instance of an object in php5? Any help appreciated... Code Example: class imageobject{ var $handle; var $height=0; var $width=0; var $directory; var $filename; //constructor function imageobject($directory,$filename,$width=0,$height=0,$color="FFFFFF") { $this->directory = $directory; $this->filename = $filename; if ($filename=="" && $width>0 && $height>0){ $new = $this->createImage($width,$height); $this = $this->createUnique($new); }elseif (file_exists($directory.$filename)){ $size = GetImageSize($directory.$filename); if ($size) $this->handle = $this->getHandle($directory.$filename,$size[2]); $this->width = $size[0]; $this->height = $size[1]; } function createUnique($imgnew) { $this->type = substr($this->output,0,3); $unique_str = $this->uniqueName(); switch ($this->type){ case "png": imagepng($imgnew,RES_DIR.$unique_str); break; default: imagejpeg($imgnew,RES_DIR.$unique_str,$this->quality); break; } $this->handle && imagedestroy($this->handle); $newobject = new imageobject(RES_DIR,$unique_str,$this->type); return $newobject; } )//end class
