Embedding PHP in HTML
You embed PHP code into a standard HTML page. For example, here’s 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 you can use to output data.
There are a few different ways to 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 coexist 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 them with semicolons: ...
