recursive array merge

[c-holtermann]

Nested get var values get lost if array merge is not recursive.

I have a form. The results get transmitted via POST. I can access date[startdate] using

###EXPRESSION.gp:date|startdate###

in extension https://extensions.typo3.org/extension/templatedisplay/
If I submit the same data using GET (something like http://mytypo3usingrealurl/?date[startdate]=XYZ) I can't access the value. When debugging I found that the values get lost during the array merge of get and post vars. Doing the merge recursively solved the problem for me.

I'm still running 6.2 but the mechanism looks the same in this recent version. It's still array_merge. But I haven't tested it.
