arrayaccess + Iterator + json_encode = :wtf:

[nicholasstephan]

Ok - a bit of a boggle for the mind here: I'm implementing arrayaccess and Iterator to create a class that mimics array functionality, and works in loops (http://us.php.net/manual/en/class.arrayaccess.php and http://us.php.net/manual/en/class.iterator.php).

 

This works great most of the time, you can traverse the tree with []'s and plug it into a foreach loop and control the output with rewind(), valid(), current()... functions.

 

Where the thing is falling over is when I try to encode it as JSON. Does anybody know how json_encode() is gathering it's data. It's not looping through the content the same way foreach does. What it ends up doing is giving me a json string representing all the public internal variables in my class, rather than the data the class is supposed to hold.

 

WTF

That's the way json_encode works on objects. Implementing arrayaccess adds some functionality to your class, but it doesn't make it an array.

 

You could add toArray() method to your class, that will return contents of the container as an array.

You can also cast your object to (array) and then json_encode it's container.
