I would need this matrix represented by a 2d field
Array
(
[0] => Array
(
[0] => .
[1] => .
[2] => .
[3] => .
)
[1] => Array
(
[0] => .
[1] => X
[2] => X
[3] => .
)
[2] => Array
(
[0] => .
[1] => X
[2] => X
[3] => .
)
)
on a string in the form.
'.... \n
.XX. \n
.XX.\n
....'
Thank you in advance for any advice.

Use array_map()
to call implode()
on each element to get an array of strings. Then implode that to get a single string separated by \n
.
$result = implode('\n', array_map('implode', $array));
