In PHP, can i use put echo inside a variable?

Question

I wrote this:

<!DOCTYPE HMTL>
<html>
    <head>
    </head>
    <body>
        <?php
            $javascript = echo '<script type = "text/javascript">',
            'prompt("Hello");', '</script>';;
        ?>
    </body>
</html>

And it says:

Parse error: syntax error, unexpected 'echo' (T_ECHO) in C:\xampp\htdocs\h.php on line 7

You can't. Decide if you want to echo or assign to a variable. Or assign to the variable, the echo it out. — aynber, Dec 23 '16 at 17:10
Echo isn't a function and doesn't have a return value, so I'm not sure what the goal is here. — Devon Bessemer, Dec 23 '16 at 17:11

`= "string" ?>` == `` **since PHP v5.4** – Mihailo Dec 23 '16 at 17:23
@Mihailo That's supported way before 5.4, probably since the very beginning of PHP, except the `short_open_tag` option can disable it before 5.4 as `=` was recognized as a special short tags case as it's easy to distinguish from XML's ``: http://php.net/manual/en/language.basic-syntax.phptags.php – Ultimater Dec 23 '16 at 17:27
@Ultimater yup I know. I didn't feel like it was necessary to write the details. But sure now we have the details as well. – Mihailo Dec 23 '16 at 17:42

You can simply echo the script using echo (without even using the variable)

<?php
echo '<script type = "text/javascript">prompt("Hello");</script>';
?>

Or Using variable

<?php
echo $javascript = '<script type = "text/javascript">prompt("Hello");</script>';
?>

Or using shorthand

<?='<script type = "text/javascript">prompt("Hello");</script>'?>

In PHP, can i use put echo inside a variable?
