title: MySQL and date() query
body: <p>Let's say I have records in a MySQL table that have a unix timestamp in it. How would I go searching, in a MySQL query, for a query that was posted on the current month?</p>
  
  <p>Here's what I have so far:</p>
  
  <pre><code>$sql = "SELECT * FROM `postings` WHERE `date_posted` = '".date("m-Y")."'";
  </code></pre>
  
  <p>Obviously -- not right. Help?</p>
