Warning: date_format() expects parameter 1 to be DateTime

I am using the following script to pull the calendar info out of the mysql database and display it on the page. I am trying to re format the date from the standard Mysql date format , but when retrieving it from the database am getting the following error :

Warning: date_format() expects parameter 1 to be DateTime, string given in C:\easyphp\www\twinfocus\managecalendar.php on line 24

Warning: date_format() expects parameter 1 to be DateTime, string given in C:\easyphp\www\twinfocus\managecalendar.php on line 24

Warning: date_format() expects parameter 1 to be DateTime, string given in C:\easyphp\www\twinfocus\managecalendar.php on line 24

Warning: date_format() expects parameter 1 to be DateTime, string given in C:\easyphp\www\twinfocus\managecalendar.php on line 24


The Database (as you can see the dates are stored correctly):
enter image description here

The script :

<?php
$sql2 = <<<SQL
SELECT *
FROM `calendar`
SQL;
if(!$result2 = $db->query($sql2)){ die('There was an error running the query [' . $db->error . ']');}
echo '<table class="admintable"> <thead>';
echo '<tr><th>Client Names</th><th>Email</th><th>Tel</th><th>Wedding Date</th><th>Date Created</th><th>Start Time</th><th>End Time</th><th>Price</th><th>Location</th><th>Other Info</th><th>Edit</th><th>Delete</th></tr></thead>';
while($row2 = $result2->fetch_assoc()){
$weddingdate = $row2['weddingdate'];
$formattedweddingdate = date_format($weddingdate, 'd-m-Y');
echo '<tr><td>'.$row2['name'].'</td><td>'.$row2['email'].'</td><td>'.$row2['tel'].'</td><td style="min-width:70px;">'.$formattedweddingdate.'</td><td style="min-width:70px;">'.$row2['datecreated'].'</td><td>'.$row2['starttime'].'</td><td>'.$row2['endtime'].'</td><td>&pound;'.$row2['price'].'</td><td>'.$row2['location'].'</td><td style="min-width:400px;">'.$row2['otherinfo'].'</td><td><a href="managecalendar.php?&key='.$key.'&editwedding='.$row2['id'].'">Edit</a></td><td><a href="calenderdelete.php?&key='.$key.'&delwedding='.$row2['id'].'">Delete</a></td></tr>';}
echo '</table>';

?>

Answer

Best way is use DateTime object to convert your date.

$myDateTime = DateTime::createFromFormat('Y-m-d', $weddingdate);
$formattedweddingdate = $myDateTime->format('d-m-Y');

Note: It will support for PHP 5 >= 5.3.0 only.
