I have this javascript array 

   <script>
$(function() {
 var foo= [ "one",
            "two",
            "three",
            "one",
            "final"];
</script>

Now, I am trying to replace the foo with a PHP array. 

<?php $array = array("sky","mac","rain","bob","sep","ion"); ?>

Now, I tried 

<script>
    $(function() {
     var foo= [<?php array("sky","mac","rain","bob","sep","ion"); ?> ];
    </script>

But, it seems not to be working

    You can't just echo an array. Commented Mar 3, 2013 at 12:45
  • This is the ideal use case for the json_encode function. Commented Mar 3, 2013 at 12:46

IN PHP you can use the method json_encode() to convert most PHP arrays into JSON, which is a legit object in JavaScript.

<?php $array = array("sky","mac","rain","bob","sep","ion"); ?>

<script>
// ...
var foo = <?php echo json_encode( $array ); ?>;
// ...
</script>

What is the benefit of this rather than the previous answer? @Sirko
See my comment below the previous answer.
@Simon Less verbose. Usage of a built-in-method almost always is better than reinventing the wheel. The same command can be used to transfer multi-level-arrays / objects. ...
@Sirko thanks, I've learned a new thing today. But, the I wanted to use this code for another project, and got another problem. I guess I'll ask a new question. Help if you can pls.

This does not guarantee the values being properly escaped/encoded for JavaScript. json_encode() should be used in stead as suggested in the other answer
For example, if the PHP array contains ', rest of the JavaScript will me messed up.
