PHP, like several other web languages, uses a pair of tags to include the PHP code part to distinguish it from the HTML code. PHP has a total of 4 tag styles.
1.xml style
echo "This is an xml style tag";
?>
XML-style tags are commonly used tags and recommended tags. The server cannot disable them. This style of tags can be used in both xml and xhtml.
2.Script style
echo'This is a script-style tag';
3. Short style
4.asp style
<%
echo'This is an asp style tag';
%>
