Answer 1

You can use echo , print_r or var_dump ;

Echo command printing only strings. (cannot convert array to string)

Print_r command printing strings and arrays (recursive).

Var_dump command printing string and arrays. (with variable type)

I think the best way for this code will be echo , because you wan't print string.

Example:

echo "Demux Format is empty\\n"

foreach ($errors as $error) { echo "$error[message]\\n"; }

\\n is new line
