Embedding PHP in HTML
You embed PHP code into a standard HTML page. For example, hereâs how you can dynamically generate the title of an HTML document:
<HTML><HEAD><TITLE><?echo $title?></TITLE> </HEAD>...
The <?echo $title?>
portion of the document
is replaced by the contents of the $title
PHP
variable. echo
is a basic language statement that
you can use to output data.
There are a few different ways that you can embed your PHP code. As
you just saw, you can put PHP code between <?
and ?>
tags:
<? echo "Hello World"; ?>
This style is the most common way to embed PHP, but it is a problem
if your PHP code needs to co-exist with XML, as XML may use that
tagging style itself. If this is the case, you can turn off this
style in the php3.ini
file with the
short_open_tag
directive. Another way to embed PHP
code is within <?php
and
?>
tags:
<?php echo "Hello World"; ?>
This style is always available and is recommended when your PHP code
needs to be portable to many different systems. Embedding PHP within
<SCRIPT>
tags is another style that is
always available:
<SCRIPT LANGUAGE="php" > echo "Hello World"; </SCRIPT>
One final style, where the code is between <%
and %>
tags, is disabled by default:
<% echo "Hello World"; %>
You can turn on this style with the asp_tags
directive in your php3.ini
file. The style is
most useful when you are using Microsoft FrontPage or another HTML
authoring tool that prefers that tag style for HTML embedded scripts.
You can embed multiple statements by separating ...
