What Are Language Tags?

The Language Tags are used to be recognized by the language parser or compiler.

Example 17:

<?php

PHP code goes here;

?>

<?php……?> is PHP language tags, which means all PHP code should be put in here.

Example 18:

<script>

JavaScript code goes here;

</script>

<script>……</script> is JavaScript language tags, which means all JavaScript code should be put in here.

Note:  Many languages have no language tags, they use other instructions to mark the beginning and ending of the program.
