It is probably the meaning of a pure-handed taxi. It is best to put the data out and test it:

Function array_unzip_rescursive ($ arr) {$ res = array (); if (array_key_exists ('name', $ arr) $ res [] = $ arr; else foreach ($ arr as $ item) $ res = array_merge ($ res, array_unzip_rescursive ($ item); return $ res ;}

Foreach ($ arr ['1'] as $ row) {$ res [] = $ row ['0'];}
