Convert content of file to JavaScript array

So I know file() returns every new line into an array.

$plugins = file("plugins.txt");
foreach($plugins as $plugin) {
    echo $plugin;
 }

Which returns

item1 item2 item3

In one line. Though, I know PHP thinks it's an array, JS doesnt, if I convert the above PHP script into a function and then do:

var pluginsList = <?php echo filetoArray(); ?>;

Which returns in console

var pluginsList = item1 item2 item3

While I was hoping for:

var pluginsList = [item1,item2,item3];

How would I make sure it reutns an array so JS can read?

EDIT: So thanks to the answers, I got an array finally. But it returns like this:

["item1\r\n","item2\r\n","item3\r\n","item4"]

Though, I want the \r\n to be removed. What I have so far: the str_replace doesn't do anything, it's the same.

    $plugins = file("plugins.txt");
    $plugins = json_encode($plugins);
    $plugins = str_replace("\n\r", "", $plugins);
    echo $plugins;

Easy as this:

$plugins = file("plugins.txt");
$plugins = str_replace(array("\r\n", "\r", "\n"), '', $plugins);
$output = json_encode($plugins);
print $output;
