PHP Filtering Function
<p>I've built a blog similar to wordpress. On my home page, I take the entire blog post, throw it  through a function, and only display an excerpt of it. I want to go through and shrink my videos to a specific width/height. The code in the post could look like:</p>

<pre><code>[vimeo width="700" height="400"] // (the 700 &amp; 400 could be any values). 
</code></pre>

<p>I basically want to find that, then change it to:</p>

<pre><code>[vimeo width="300" height="200"] // this will be preset/hard coded.
</code></pre>
