JS <---> PHP Communication

Solution 1:

<script type="text/javascript">
var string = <?php echo $variable; ?>;
</script>

or AJAX

Solution 3:

You can create a js file with PHP.

For exemple

// My script php
var js_var = '<?php echo "toto"?>';

or use an AJAX framework and JSON

Solution 4:

What's the method you're using to communicate with PHP? If you're using AJAX you might want to checkout jQuery or a library of some sort and use JSON for communication.

Using these methods, like using getJSON, you can easily access the variables returned by the PHP-script.

Please provide some more details to your question so we can answer your question in more detail and provide some examples.

Solution 5:

You can assign php values to JavaScript like so:

var x = <?php echo $varible ; ?>;
