Array_map fails

  array-map, arrays, php, transpose

I am using the function array_map to transpore arrays

The point is that it does work for small arrays, but with the arrays getting bigger the functions returns the following errors:

Warning: Only arrays and Traversables can be unpacked in /web/htdocs/www.mosaic-dev.it/home/IA/ia2.php on line 379

Warning: array_map() expects at least 2 parameters, 1 given in /web/htdocs/www.mosaic-dev.it/home/IA/ia2.php on line 379
