How to rebuild this array?

Question

PHP

Good afternoon.
There is an array of objects. In the layout, the rows are separated by row-blocks, 2 or 3 elements each, depending on whether one of the objects has the "large block" parameter set.
As an option - to correct the layout, yes, but there is no desire to dig it up.
How to rebuild the array in such a way that the main keys are the same rows, and the elements inside them are objects, of course, given that there may be an object with a large block

Answer 1

This is usually done in js: https://masonry.desandro.com/
But if you are not looking for easy ways, you can rebuild the array, but where is the example of the array?
