How can we access PHP variables in JavaScript or jQuery rather than php echo variable

How do I access PHP variables in JavaScript or jQuery?

<?php echo $variable1 ?>
<?php echo $variable2 ?>
<?php echo $variable3 ?>
...
<?php echo $variablen ?>

I know I can store some variables in cookies, and access these values via cookies, but values in cookies are relatively stable values. Moreover, there is a limit, you can not store many values in cookies, and the method is not that convenient. Is there a better way to do it?

Hello @kartik,

You can also use json_encode for more complex things like arrays:

<?php
    $simple = 'simple string';
    $complex = array('more', 'complex', 'object', array('foo', 'bar'));
?>
<script type="text/javascript">
    var simple = '<?php echo $simple; ?>';
    var complex = <?php echo json_encode($complex); ?>;
</script>

Other than that, if you really want to "interact" between PHP and JavaScript you should use Ajax.

Using cookies for this is a very unsafe and unreliable way, as they are stored clientside and therefore open for any manipulation or won't even get accepted/saved. Don't use them for this type of interaction. 

Hope this works!!
