Question

I do this to get file content into array:

$array = file('sample.txt', FILE_IGNORE_NEW_LINES);

How to reverse this? If I have the array already how to write it to a file, each value in a seperate line.

Answer 1

It would not make sense to put each value on a different row. You’re probably looking for serialize.

If you really want each element on it’s own line, you could use implode:

$str = implode("\n", $array);
file_put_contents($file, $str);
