Question

I want to save current path information in an Array and one field is a part of another. Can I access a field of the same array during initialization?

$this->path = array
(
     'rel_image' => '/images',
     'document_path' => '/a/file/path',
     'path' => $this->path['document_path'].$this->path['rel_images']
);

or do I have to initial them one by one?

The array still is undefined while you’re defining it. However you can define other (temporary) variables to do so on the fly:

$this->path = array
(
     'rel_image' => $r = '/images',
     'document_path' => $p = '/a/file/path',
     'path' => $p.$r
);

However that normally should not be needed, as you’re duplicating data within the array. Just saying, you can do whatever you want 🙂
