passing php values to js file

simple jquery document ready and then I need some value from php to be alerted for example remote address. 

$(document).ready(function() {
    string1="<?= $_SERVER['REMOTE_ADDR'] ?>";
    alert(string1);

When I write like this result is 

<?= $_SERVER['REMOTE_ADDR'] ?>

What's wrong ? no way to pass some php inside js file ?

Make sure that your web server allows tags, maybe try . Secondly rather than trying to write to a .js file. You should use a .php file and write the JavaScript inside the HTML within tags.

PHP code cannot be executed in files with extensions other than .php/.php5 (you might have used .js or .html)

Try this

<?php echo "<script type=''text/javascript>"; ?>
$(document).ready(function() {
    string1="<?php echo $_SERVER['REMOTE_ADDR']; ?>";
    alert(string1);
});
<?php echo "</script>"; ?>

Save the file as .php

Try using the normal tags and print with an echo.

The file has to be run through the PHP pre-processor. This is usually done by giving the file a .php file extension (although you can configure webservers so that isn't needed).

If you are serving up something that isn't HTML, then make sure you specify the content type.

header("Content-Type: application/javascript");

From what I know you can't, because JS is client based and PHP is server based.
