I am running into problems accessing objects that I have nested within other objects. I am using PHP 5. My workstation is Windows XP, but I'm not sure about the details of the webserver where I work. It might be linux, it might be some version of windows, or some combination. I'm pretty sure the webserver runs Apache. (If the answers to those questions are critical, I will ask my boss whenever he comes back from sick leave.) Anyway, this is my problem. I first tried using subclasses but discovered that PHP does not allow this, so I included the files for the subclasses into the main class. That little workaround has allowed me to put objects within other objects, but now I can't get them back out! How do I access nested objects? I have tried searching Google and this site's archive, but I'm having trouble finding anything. I am currently trying something like this. I cannot get this approach to work. What am I doing wrong? file1.php <?php include_once( "file2.php" ); class SuperClass { $this->nestedObjects = array(); function addObject( $object ) { array_push( $this->nestedObjects, $object ); } function getObjectNumber( $n ) { return $this->nestedObjects[ $n ]; } } ?> file2.php <?php class SubClass { function __construct( $name ) { $this->name = $name; } function getName() { return $this->name; } } ?> file3.php <?php include_once( "file1.php"); $a = new SuperClass(); $b = new SubClass( "example" ); $a->addObject( $b ); $c = $a->getObjectNumber( 0 ); $c->getName(); ?> Basically, my problem is that the last line of code in file3, $c->getName(), does not work. I keep getting an error message like this one: [b]Fatal error: Call to a member function getName() on a non-object in file3.php on line 7[/b] I absolutely cannot figure out how to access the nested object! Please help. Is my approach wrong? Does PHP just not support this? Is there a workaround? Thank you all for your time.
