How do you call a variable in PHP?

For something seemingly so straight-forward, you would think that the information out there would be a bit better on this subject. Passing a variable from PHP to JavaScript is actually very easy! There are just a couple things you need to keep in mind and some ways to do it to ensure it actually works.

I find that putting the following code into the <head> section of my website is the most foolproof method:

<?php

$php_variable='string';//Define our PHP variable. You can of course get the value of this variable however you need.

That’s it! You just define the PHP variable first, then echo it into a basic JS variable declaration statement. I know there are lots of ways to define a JavaScript variable, but this is the one I find works in the most circumstances. I’m not an expert here, but most of the others seem to not work a lot of the time.

A few things to keep in mind for this:

1. The PHP variable needs to be defined before the JS one.
2. The JS variable needs to be defined before you actually use it anywhere. This seems obvious, but if you forget this fact and try to put this declaration into the footer of your site and then use it in the content, you’ll find it doesn’t work! That’s why I like to put this in the head section of my website. Or, if you were in WordPress or another CMS, make sure to place it in the header.php file of your active theme.

Additionally, you should be aware that if your variable is not a string and is instead a number, you would want to define it without the quotes around it, i.e.:

Note that as Sherri mentioned in the comments, if you have more complicated strings or any strings with quotes (“) in them, this will break. You’ll want to look into json encoding if needed. But for simple strings and variables, this should do the trick.

Hard to go wrong with any of this. There are of course more complicated ways to use this, but I’m not going to go into any of those here. Let me know if you have any problems!

</body>

<html>

Output:

<?php

setcookie($cookie_name, $cookie_value);

if(!isset($_COOKIES[$cookie_name])) {

print("Cookie created | ");

}

?>

<script type="text/javascript">

var x = document.cookie;

document.write(x);

</script>

</body>

<html>

Output:

PHP provides a method to set the cookie using the setCookie() method. Here, we can set the data or variable in PHP cookie and retrieve it from JavaScript using document.cookie.

Install local server like XAMPP server into your system.
Save the file in htdocs folder using the name geeks.php
Start Apache server.
