I have this array out put now i need to reverse the array but without changing its keys. i like to start the foreach loop from last array to first. thanks

Answer 1

array array_reverse ( array $array [, bool $preserve_keys = FALSE ] )

preserve_keys If set to TRUE numeric keys are preserved. Non-numeric keys are not affected by this setting and will always be preserved.

e.g.

array_reverse($input, true);
