Reversing the PHP file() function

Question

I converted a .php file to an array using the file() function.
Now I modified the array and I want to put all it contents back to the file (keeping line endings)...
Someone can tell me if there is a function that does the opposite of file()?
I want to bypass the annoying "array to string conversion" way...

Thanks in advance!

Answer 1

Use file_put_contents() and implode():

file_put_contents('/your/file.php', implode(PHP_EOL, $fileArray));
