Here's a way to tackle this kind of thing in the future:
Divide and Conquer.
print_r($foo) prints out a BUNCH of stuff.
Focus only on the outer layer:
> i have an array, i can do a print_r($foo) and get the following:
> Array
> (
> [bookmark] => 1
> [facets] => Array
..
..
..
Then simply do:
print_r($foo['facets']);
Now you can ignore a bunch of crap you don't care about.
Focus on the outer layer and begin again:
Array
(
[0] => Array
(
[lastname] => <form id="facet-lastname">
<input type="hidden" name="list" value="" />
<input type="hidden" name="offset" value="0" />
<input type="hidden" name="orderBy" value="username" />
<input type="hidden" name="sort" value="asc" />
<strong>Name:</strong>
<input type="text" name="_lastname" value="" style="width: 125px" />
<input type="submit" value="Search" />
</form>
}
Okay, now we have:
print_r($foo['facets'][0]);
Array
(
[lastname] => <form id="facet-lastname">
<input type="hidden" name="list" value="" />
<input type="hidden" name="offset" value="0" />
<input type="hidden" name="orderBy" value="username" />
<input type="hidden" name="sort" value="asc" />
<strong>Name:</strong>
<input type="text" name="_lastname" value="" style="width: 125px" />
<input type="submit" value="Search" />
</form>
}
Finally, print_r($foo['facets'][0]['lastname'] is your answer.
It won't always be [] -- If you are using objects you might need -> in
there somewhere.
Figuring out where gets a lot easier if you focus on the Big Picture --
only the outer layer of your data structure, and drill down.
If at some point you know you need *ALL* the elements of an array, that's
easy enough.
That's the point at which you put in a loop to walk through them.
BUUUUUT
During your development, write the loop, see that it dumps out all the
elements, or at least a whole lot of stuff, and then stick an "exit;" at
the end, and focus on JUST the first element to tear that apart.
You can take the exit; out when you are all done, and it will work for all
the elements, assuming your data is well-formed.
In the meantime, focus on the outer layer, and focus on just ONE element
at a time, to avoid confusing yourself.
I do this all the time, especially when I'm dealing with somebody else's
structured data, and I don't really know what they've done.
