I have this so far trying to only display the current days tide info so I can output it. What am I doing wrong. Look at the xml file and I want only the current days "Events"

$url = 'http://tides.obinet.net'; 
$xml = simplexml_load_file($url);



echo '<b>Tide Data </b><br />'; 
echo $xml->Date, '<br />'; 
echo $xml->Activity, '<br />'; 
echo $xml->Time, ' <br />';
echo $xml->Height, ' <br />';

<?php
$url = 'http://tides.obinet.net';
$xml = simplexml_load_file($url);
foreach($xml->Tidedata->Day as $day)
{
   if($day->Date == date('Y-m-d'))
   {
      echo "<table>\n";
      foreach($day->Event as $event)
      {
         printf("<tr><td>%s:</td><td>%s%s</td></tr>\n",
                $event->Time,
                $event->Activity,
                (isset($event->Height)) ? " ({$event->Height})" : '');
      }
      echo "</table>\n";
      break;
   }
}
?>

Thanks this works great. one more question.

What is I only wanted the high and low tide for the day not the sunrise, sunset, moonrise, moonset info. These are events so I dont know how you could seperate them from the tide events.

Thanks

You could just use an if/continue within the inner foreach loop, something like this (making sure the two activity names in the array $activities are correct):

<?php
$url = 'http://tides.obinet.net';
$xml = simplexml_load_file($url);
// add this:
$activities = array('High Tide', 'Low Tide');
foreach($xml->Tidedata->Day as $day)
{
   if($day->Date == date('Y-m-d'))
   {
      echo "<table>\n";
      foreach($day->Event as $event)
      {
         // and add this:
         if(!in_array($event->Activity, $activities))
         {
            continue; // go to next event
         }
         printf("<tr><td>%s:</td><td>%s%s</td></tr>\n",
                $event->Time,
                $event->Activity,
                (isset($event->Height)) ? " ({$event->Height})" : '');
      }
      echo "</table>\n";
      break;
   }
}
?>
