Help comparing conditions and returining multiple results

I wnat to evaluate the date in Wordpress and give multiple answers

Hello,

I am trying to insert a PHP snippet in a wordpress post. I am using the execphp to allow the running of php code.

I have the following code working and displaying. I would like to create a snippet that would allow me to echo multiple responses if multiple conditions are met. Any suggestions on how to this.

Please note, I am not an educated coder. I merely cobble together things that look like they may work.

Here's my code: (Wordpress uses "the_date()" to retrieve the date the post was made.)

<p>Publication was on <?php echo the_date('Y-m-d'); ?>

<? function dateDiff ($d1, $d2) {
// Return the number of days between the two dates:
 return round(abs(strtotime($d1)-strtotime($d2))/86400);
} // end function dateDiff
?>

<?php 
 $date_01 = get_the_date('U');
 $date1 = date('Y-m-d', $date_01);
 $date2 = '2011-12-15';
 echo (dateDiff($date1, $date2));
?>

<?php
if ((dateDiff($date1, $date2)) > 30)
 echo '<p>If the post was over 30 days ago, they get this and the prior messages';
elseif ((dateDiff($date1, $date2)) > 20)
 echo '<p>If the post was over 20 days ago, they get this and the prior message';
else
 echo '<p>If the post was made under 20 days ago, they get this message only';
?>

if ... else if .... else
This structure allows only one of them to be met at a time.

if ((dateDiff($date1, $date2)) > 30) {
echo '<p>If the post was over 30 days ago, they get this and the prior messages';
}

if ((dateDiff($date1, $date2)) > 20) {
echo '<p>If the post was over 20 days ago, they get this and the prior message';
}

The above code, for example, allows you to return two separate message if the two conditions are met. I hope you see where this is going.

Umm . . slight mod. :-)

$msg = null;

if ((dateDiff($date1, $date2)) > 30) {
$msg .= ' some over 30 day message';
}

if ((dateDiff($date1, $date2)) > 20) {
$msg .= ' some over 20 day message';
}

if ($msg) { echo "<p>$msg</p>"; }
