Warning: trim() expects parameter 1 to be string, array given in C:\xampp\htdocs\application.php on line 34
not sure what is ambigous about this warning. it tells you that you pass an array where you should pass a string.

reason being, you declare Skills to be an input array, so the foreach() loop's $value will be an array (and not a string like the others) for the skills key.

the second error is caused by the first error. just fix that one and it should go away.
