php variable in html no other way then: <?php echo $var; ?>

Question

hi i work a lot in mixed html and php and most time i just want solid html with a fet php variables in it so my code look like this

<tr><td> <input type="hidden" name="type" value="<?php echo $var; ?>" ></td></tr>

wich is quite crap isnt there little code something like:

<tr><td> <input type="hidden" name="type" value="$$var" ></td></tr>

but then working?

this is possible to but you get stuck with the ""es (you have to replace them all with '') and the layout is gone

echo "<tr><td> <input type="hidden" name="type" value="$var" ></td></tr>"

anything better? thanks Matthy

Answer 1

There's the short tag version of your code

<tr><td> <input type="hidden" name="type" value="<?= $var ?>" ></td></tr>

which requires short tags be enabled in your php configuration. It functions exactly as the code you typed; these lines are literally identical in their internal implementation:

<?= $var1, $var2 ?>
<?php echo $var1, $var2 ?>

That's about it for built-in solutions. There are plenty of 3rd party template libraries that make it easier to embed data in your output, smarty is a good place to start.

Answer 2

Use the HEREDOC syntax. You can mix single and double quotes, variables and even function calls with unaltered / unescaped html markup.

echo <<<MYTAG
  <tr><td> <input type="hidden" name="type" value="$var1" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var2" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var3" ></td></tr>
  <tr><td> <input type="hidden" name="type" value="$var4" ></td></tr>
MYTAG;

Answer 3

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

Answer 4

I'd advise against using shorttags, see http://stackoverflow.com/questions/200640/are-php-short-tags-acceptable-to-use for more information on why.

Personally I don't mind mixing HTML and PHP like so

<a href="<?php echo $link;?>">link description</a>

As long as I have a code-editor with good syntax highlighting, I think this is pretty readable. If you start echoing HTML with PHP then you lose all the advantages of syntax highlighting your HTML. Another disadvantage of echoing HTML is the stuff with the quotes, the following is a lot less readable IMHO.

echo '<a href="'.$link.'">link description</a>';

The biggest advantage for me with simple echoing and simple looping in PHP and doing the rest in HTML is that indentation is consistent, which in the end improves readability/scannability.

I really think you should adopt Smarty template engine as a standard php lib for your projects.
