Symfony templates are simple HTML embedded with PHP in them.
For this reason they present the following downsides:
* An extra amount of unneeded whitespace exists. Since you'd prefer to
have a readable file, you organize it nicely. However, the generates
files are needlessly bigger.
* There's a price for PHP going in and out of scripting mode by using
<?php and later ?>.
* There's a price for calling PHP's echo again and again instead of
once.
Though these prices may be negligible for some sites, I feel they are
becoming more and more costly for dynamic sites. Also, the template is
not that readable with <?php and ?> cluttering it everywhere.
Your opinions / insights are welcomed.
Here's a sample of two alternative:
Symfony style:
<ul>
<li><?php echo link_to('1', 'module/action');?></li>
<li><?php echo link_to('2', 'module/action');?></li>
<li><?php echo link_to('3', 'module/action');?></li>
<li><?php echo link_to('4', 'module/action');?></li>
<li><?php echo link_to('5', 'module/action');?></li>
<li><?php echo link_to('6', 'module/action');?></li>
</ul>
A more optimized PHP script could be:
<?php echo '<ul><li>'
.link_to('1', 'module/action')
.'</li><li>'
.link_to('2', 'module/action')
.'</li><li>'
.link_to('3', 'module/action')
.'</li><li>'
.link_to('4', 'module/action')
.'</li><li>'
.link_to('5', 'module/action')
.'</li><li>'
.link_to('6', 'module/action')
.'</li></ul>'
;
The second script, although looks less like HTML, produces a
whitespace-free output, uses a single echo command and doesn't force
PHP's parser to go back and forth. Of course in this small example the
differences are meaningless but I hope you understand my point.
