  1. POHow could you create a "content_for" equivalent in PHP?
    text
    copied!<p>I've been working on a small page in PHP, one that doesn't need the power of a full-fledged framework behind it. One thing that I'm really missing from previous work in Ruby-on-Rails is the ability to effectively pass content up the page using "content_for".</p> <p>What I was wondering is, how could you create a page lifecycle that would accomplish this same effect in PHP?</p> <p>So, here's a simple example:</p> <p>Let's say you have a template that defines an index page, just a recurring header and menu you want to use on all your pages. So your <code>index.php</code> file looks basically like this:</p> <pre><code>...header stuff... &lt;body&gt; &lt;?php include $file.'.php'; ?&gt; &lt;/body&gt; ...footer stuff... </code></pre> <p>EDIT: Thanks for the tips on URL security, but let's just assume I'm getting the user request safely :)</p> <p>Now, lets say in the header you want to put this:</p> <pre><code>&lt;head&gt; &lt;title&gt;&lt;?php echo $page_title; ?&gt;&lt;/title&gt; &lt;/head&gt; </code></pre> <p>It would be nice to be able to specify the title in the included file, so at the url <code>http://example.com/index.php?p=test</code> you're loading <code>test.php</code>, and that file looks like this:</p> <pre><code>&lt;?php $page_title = 'Test Page'; ?&gt; ... rest of content ... </code></pre> <p>Now, obviously this doesn't work, because the including page (index.php) is loaded before the variable is set.</p> <p>In Rails this is where you could pass stuff 'up the page' using the <code>content_for</code> function.</p> <p><strong>My question is this: What would be the simplest, leanest way that you all can think of to effect this kind of 'content_for' functionality in PHP?</strong></p> <p>Ideally I'd like suggestions that don't involve strapping on some big framework, but some relatively light boilerplate code that could be used in a lot of different applications.</p>
