PHP file_put_contents new line issue

Question

I'm unable to write array to text file in new lines. My code:

echo '<pre>';
print_r($final_result);
echo '</pre>';

Output:

Array

(
    [0] => Something1
    [1] => Something2
    [2] => Something3
)

Then:

file_put_contents($file, trim($final_result . "\n"), FILE_APPEND);

Output:

Something1Something2Something3Array

My goal is:

Something1
Something2
Something3

Any ideas? :)

How about

file_put_contents($file, implode(PHP_EOL, $final_result), FILE_APPEND);
