strtotime makes a date string into a timestamp. You want to do the opposite, which is <a href="http://us.php.net/manual/en/function.date.php" rel="noreferrer">date</a>. The typical mysql date format is <code>date('Y-m-d H:i:s');</code> Check the manual page for what other letters represent.

If you have a timestamp that you want to use (apparently you do), it is the second argument of <code>date()</code>.

Use PHP's <a href="http://php.net/date"><code>date()</code></a> function.

Example:

<pre><code>echo date('m/d/Y', 1299446702);
</code></pre>

If you are using PHP <code>date()</code>, you can use this code to get the date, time, second, etc.

<pre><code>$time = time(); // you have 1299446702 in time
$year = $time/31556926 % 12; // to get year
$week = $time / 604800 % 52; // to get weeks
$hour = $time / 3600 % 24; // to get hours
$minute = $time / 60 % 60; // to get minutes
$second = $time % 60; // to get seconds
</code></pre>

If anyone wants timestamp conversion directly to a DateTime object, there's a simple one-liner:
<pre><code>$timestamp = 1299446702;
$date = DateTime::createFromFormat('U', $timestamp);
</code></pre>
Following @sromero comment, timezone parameter (the 3rd param in DateTime::createFromFormat()) is ignored when unix timestamp is passed, so the below code is unnecessary.
<pre><code>$date = DateTime::createFromFormat('U', $timestamp, new DateTimeZone('UTC'); // not needed, 3rd parameter is ignored
</code></pre>

How can I convert that to a readable date/time in PHP? I have tried srttotime, etc. to no avail.
