Use PHP implode to convert your Array to a string that you can echo. Using echo on an array will just display the data type.
return implode[' ', $errors];
If you want to separate the errors with a delimiter other than a space, just replace the space in the first parameter:
return implode[' :: ', $errors];
For example, if your errors array contained three values:
[ "Invalid data" , "404" , "Syntax error" ]
then your
string, if you used the ::, would look like this when you run echo on the result:
Invalid data :: 404 :: Syntax error
See the reference link I included for another example.

it should be noted that an array with one or no elements works fine. for example:
