When i use the php and js separately it is working correctly
<script> var test = 'asdasdasd'; </script> <?php $id =
"<script>document.write(test)</script>"; echo $id; ?>
But when I use the php inside the js function it is not working correctly
<script> var test = 'asdasdasd'; <?php $id =
"<script>document.write(test)</script>"; echo $id; ?> </script>
How can make work my second code?
The second code produces wrong HTML/JS:
<script> var test = 'asdasdasd'; <script>document.write(test)</script> </script>
- see for yourself in the generated page.
Since everything between <script> and </script> is considered to be JS code, it will try to parse the inner <script> as Javascript code...and fail.
I think the inner other of <script>...</script> tags (those that are in PHP markup) is not needed at all, just get rid of them and it will work.
You can insert any value from php to absolutely everywhere in your file. Literally everywhere.
While writing client-side code, in the right place open php tag <?php and echo what you need. Don't forget to write a closing tag ?> afterwards.
Here, you are echoing the opening script tag, which you already wrote before. That results in a syntax error:
<script>
<script>
...
</script>
