[PHP] Howdy (new in here)
Hi everyone! I'm just starting out with PHP so I'm looking for a good place to ask some questions, have my code critiqued (read: visciously ripped apart), and generally BS about PHP and programming in general (if that's OK). I know that PHP sometimes has a reputation for having (some) lousy developers, and I'd like to avoid becoming one of those people. To that end, I've subscribed here because I've always found mailing lists to have much higher-quality discourse than the average online foum. Looking forward to participating! - BW P.S, The rules page on the web (http://us2.php.net/reST/php-src/README.MAILINGLIST_RULES) is currently broken, but this one works: http://us2.php.net/reST/php-src/trunk_README.MAILINGLIST_RULES. Just a heads up to whoever is in charge of that. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Rate my (really) simple template class
So I decided to write a template class in order to get myself going on
learning PHP. Of course I wrote the simplest thing possible:
class Template
{
protected $template;
protected $vars;
public function __construct($template)
{
$this->template = $template;
}
public function __set($name, $value)
{
$this->vars[$name] = $value;
}
public function __get($name)
{
return $this->vars[$name];
}
public function __toString()
{
ob_start();
eval('?>' . $this->template);
return ob_get_clean();
}
}
Which you can use, quite simply like this:
$tpl = new Template(file_get_contents('index.tpl.php'));
$tpl->title = 'Here\'s the title';
$tpl->text = 'Blah blah blah...';
echo $tpl;
I have a few questions though.
- First, I'm storing the template as an actual string, instead of just
a path to a template file, which means I'm using eval() instead of
require() in my __toString(). My thinking was that this would avoid
reading the template file twice in the case that __toString() gets
called multiple times. But will PHP handle this automagically if I do
in fact decide to store a path to a file, and call require() instead?
- Secondly, I noticed that in the constructor, it's not necessary to
initialize $vars to an empty array, and I haven't done so. I guess PHP
automatically initializes it the first time I set one of its elements
to a value. Is this okay, or is there a better way in the name of best
practices?
- Finally, I'd like to be able to limit what things can be accessed
from the scope of the template file. As it stands, if you have a
function named blowUpTheComputer() or a gobal variable called
$dontTouchThis, a template author can easily cause trouble. They can
also access any methods and properties of the Template class. How
would you go about restricting this?
Thanks a lot!
- BW

I didn't mean to suggest anything. Nor do I necessarily subscribe to the idea (that PHP has some lousy developers). It's just something I've heard bouncing around - probably on those noisy internet forums. - BW P.S: On Tue, Feb 15, 2011 at 11:51 AM, tedd wrote: > PS: We seldom point out spelling errors, but it's good to review what you > post.

Of course, that's a ridiculous reason to choose one language over another. But to augment what you're saying, sometimes certain languages are chosen because of the availability of libraries and tools, and, more importantly, because of the availability of skilled programmers. That's especially important if a client has to expand and modify a solution in the future. - BW PS, Once again, tedd, apologies for backchanneling you... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm used to statically-typed languages. Normally I never would have passed a large structure like that on the stack. But then again, in those languages, large structures are usually passed by reference, by default. In C, the only way to pass a string or array by value is to wrap it in a struct, and in Java, objects are passed by reference (if I recall correctly). Guess that's something to get used to. - BW -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
