How to reference js in php file

#The introduction of js into php files is usually divided into two situations: the same file and external files.

1. In the same situation

You can use tags directly when introducing js in the same file, for example:

<?php
echo "<script>*********</script>";
?>

2. External files

php introduces external js files. You need to write the following content outside the body, for example:

<script src="****.js" type="javascript"></script>

The above content is for reference only!
