How would I access a value from PHP, retrieve it, and store it in my JavaScript variable?

Example:

<?php
   $name = "john"
?>

JavaScript: 

var name = john

  • If you want to pass string you need to add quotes. – jcubic May 12 '16 at 07:55
  • can we perform it without echo? – Ajay Dude May 12 '16 at 07:56
  • @AjayDude You can't, unless it's with an ajax call and an appropriate php function to return it which is an overkill to display a variable – Ralph Melhem May 12 '16 at 08:00
  • @AjayDude as mentioned above, check this answer: http://stackoverflow.com/questions/23740548/how-to-pass-variables-and-data-from-php-to-javascript If you have any trouble after trying to work on it alone, post another question and i'm sure we'll all help you – Ralph Melhem May 13 '16 at 05:52

try:

You can echo the PHP variable into your javascript while your page is created.

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

OR

<script type="text/javascript">
    var name = "<?=$name;?>";
</script>

Of course this is for simple variables and not objects.

Generate part of your JavaScript by PHP:

<?php
   $name = "john";

   echo "<javascript>var name = \"" . $name . "\";</javascript>";
?>

Eg.

<?php
   $name = "john"
?>

 <script>

 var myJSVar = <?php echo $name; ?>

 alert(myJSVar);

 </script>

In the above case, Your PHP variable must have defined before being accessed by JavaScript.

Why don't you set the PHP variable inside a hidden <div> like this: 

<div id="myvar" class="hidden"><?php echo $myphpvar; ?></div>

CSS:

.hidden {display: none; visibility: hidden;}

JavaScript:

var phpvar = document.getElementById('myvar').innerHTML;
