• Pass a PHP string to a JavaScript variable (and escape newlines) [duplicate] 14 answers

I need to echo a PHP variable into JavaScript. But I have no experience about JavaScript, I did some research but nothing worked for me.

The code

 function hide() {
   document.getElementById("myDiv").style.display="none";
   <?php echo $myVar; ?>
 }

And the $myVar looks like:

$myVar = "Hi there";

</div>

Answer 1

you can do like this in js :

var php_val = '<?php echo $myVar; ?>';
 alert(php_val);
