How can I echo HTML in PHP?
PhpHtmlTemplatesEchoPhp Problem Overview
I want to conditionally output HTML to generate a page, so what's the easiest way to echo multiline snippets of HTML in PHP 4+? Would I need to use a template framework like Smarty?
echo '<html>', "\n"; // I'm sure there's a better way!
echo '<head>', "\n";
echo '</head>', "\n";
echo '<body>', "\n";
echo '</body>', "\n";
echo '</html>', "\n";
Php Solutions
Solution 1 - Php
There are a few ways to echo HTML in PHP.
1. In between PHP tags
<?php if(condition){ ?>
<!-- HTML here -->
<?php } ?>
2. In an echo
if(condition){
echo "HTML here";
}
With echos, if you wish to use double quotes in your HTML you must use single quote echos like so:
echo '<input type="text">';
Or you can escape them like so:
echo "<input type=\"text\">";
3. Heredocs
4. Nowdocs (as of PHP 5.3.0)
Template engines are used for using PHP in documents that contain mostly HTML. In fact, PHP's original purpose was to be a templating language. That's why with PHP you can use things like short tags to echo variables (e.g. <?=$someVariable?>).
There are other template engines (such as Smarty, Twig, etc.) that make the syntax even more concise (e.g. {{someVariable}}).
The primary benefit of using a template engine is keeping the design (presentation logic) separate from the coding (business logic). It also makes the code cleaner and easier to maintain in the long run.
If you have any more questions feel free to leave a comment.
Further reading is available on these things in the PHP documentation.
NOTE: PHP short tags <? and ?> are discouraged because they are only available if enabled with short_open_tag php.ini configuration file directive, or if PHP was configured with the --enable-short-tags option. They are available, regardless of settings from 5.4 onwards.

Try it like this (heredoc syntax):
$variable = <<<XYZ
<html>
<body>
</body>
</html>
XYZ;
echo $variable;
Solution 3 - Php
You could use the alternative syntax alternative syntax for control structures and break out of PHP:
<?php if ($something): ?>
<some /> <tags /> <etc />
<?=$shortButControversialWayOfPrintingAVariable ?>
<?php /* A comment not visible in the HTML, but it is a bit of a pain to write */ ?>
<?php else: ?>
<!-- else -->
<?php endif; ?>
Solution 4 - Php
Basically you can put HTML anywhere outside of PHP tags. It's also very beneficial to do all your necessary data processing before displaying any data, in order to separate logic and presentation.
The data display itself could be at the bottom of the same PHP file or you could include a separate PHP file consisting of mostly HTML.
I prefer this compact style:
<?php
/* do your processing here */
?>
<html>
<head>
<title><?=$title?></title>
</head>
<body>
<?php foreach ( $something as $item ) : ?>
<p><?=$item?></p>
<?php endforeach; ?>
</body>
</html>
Note: you may need to use <?php echo $var; ?> instead of <?=$var?> depending on your PHP setup.
Solution 5 - Php
I am partial to this style:
<html>
<head>
<% if (X)
{
%> <title>Definitely X</title>
<% }
else
{
%> <title>Totally not X</title>
<% }
%> </head>
</html>
I do use ASP-style tags, yes. The blending of PHP and HTML looks super-readable to my eyes. The trick is in getting the <% and %> markers just right.
Solution 6 - Php
Another approach is put the HTML in a separate file and mark the area to change with a placeholder [[content]] in this case. (You can also use sprintf instead of the str_replace.)
$page = 'Hello, World!';
$content = file_get_contents('html/welcome.html');
$pagecontent = str_replace('[[content]]', $content, $page);
echo($pagecontent);
Alternatively, you can just output all the PHP stuff to the screen captured in a buffer, write the HTML, and put the PHP output back into the page.
It might seem strange to write the PHP out, catch it, and then write it again, but it does mean that you can do all kinds of formatting stuff (heredoc, etc.), and test it outputs correctly without the hassle of the page template getting in the way. (The Joomla CMS does it this way, BTW.)
I.e.:
<?php
ob_start();
echo('Hello, World!');
$php_output = ob_get_contents();
ob_end_clean();
?>
<h1>My Template page says</h1>
<?php
echo($php_output);
?>
<hr>
Template footer
Solution 7 - Php
$enter_string = '<textarea style="color:#FF0000;" name="message">EXAMPLE</textarea>';
echo('Echo as HTML' . htmlspecialchars((string)$enter_string));
Solution 8 - Php
Simply use the print function to echo text in the PHP file as follows:
<?php
print('
<div class="wrap">
<span class="textClass">TESTING</span>
</div>
')
?>

In addition to Chris B's answer, if you need to use echo anyway, still want to keep it simple and structured and don't want to spam the code with <?php stuff; ?>'s, you can use the syntax below.
For example you want to display the images of a gallery:
foreach($images as $image)
{
echo
'<li>',
'<a href="', site_url(), 'images/', $image['name'], '">',
'<img ',
'class="image" ',
'title="', $image['title'], '" ',
'src="', site_url(), 'images/thumbs/', $image['filename'], '" ',
'alt="', $image['description'], '"',
'>',
'</a>',
'</li>';
}
Echo takes multiple parameters so with good indenting it looks pretty good. Also using echo with parameters is more effective than concatenating.
Solution 10 - Php
echo '
<html>
<body>
</body>
</html>
';
or
echo "<html>\n<body>\n</body>\n</html>\n";
Solution 11 - Php
Try this:
<?php
echo <<<HTML
Your HTML tags here
HTML;
?>
Solution 12 - Php
This is how I do it:
<?php if($contition == true){ ?>
<input type="text" value="<?php echo $value_stored_in_php_variable; ?>" />
<?php }else{ ?>
<p>No input here </p>
<?php } ?>
Solution 13 - Php
Don't echo out HTML.
If you want to use
<?php echo "<h1> $title; </h1>"; ?>
you should be doing this:
<h1><?= $title;?></h1>
