I keep recieving an "Warning: Illegal string offset " error when trying to iterate over an array.

My result after using var_dump ---> array(19) { ["id"]=> int(1) ["handle"]=> string(4) "test" ["blockname"]=> string(0) "" ["project"]=> string(0) "" ["document_description"]=> string(4) "test" ["project_id"]=> string(0) "" ["revision"]=> string(0) "" ["scale"]=> string(0) "" ["document_num"]=> string(9) "test-1557" ["drawn_by"]=> string(0) "" ["approved_by"]=> string(0) "" ["checked_by"]=> string(0) "" ["issued_by"]=> string(0) "" ["drawn_date"]=> string(0) "" ["approved_date"]=> string(0) "" ["checked_date"]=> string(0) "" ["issued_date"]=> string(0) "" ["purpose"]=> string(0) "" ["notes"]=> string(0) "" }

So I assume it is actually an array?

And then I also check that its an array before running the loop. The error is repeated for the number of times I expect the loop to run, so it seems to be 'iterating'. Im just not getting the expected result.
