php - How can i display one link instead of multiple links? - 


<?php include 'precode.php'; include 'header.php'; echo '<body><div class="standardlayout">'; include 'systemmenu.php'; echo '<h4>all charges</h4>';  $user = unserialize($_session['user']);   $query = "select * billingitems  userid= ' ".$user->userid. " '   order deliverytimestamp desc";  $result = mysqli_query($db, $query); while($row = mysqli_fetch_array($result)) {     echo '<p>';      echo '<a href="billinghistory1.php?deliverytimestamp=' .$row["deliverytimestamp"]. '">'.    ' order delivered on' . '</a>' .$row['deliverytimestamp']  ; }  echo '</div></body></html>';  $_session['user'] = serialize($user); include 'footer.html'; ?>

output of above file:

  charges    order delivered on2015-05-06 13:26:50   order delivered on2015-05-06 13:26:50   order delivered on2015-05-06 13:26:50   order delivered on2015-05-03 22:11:23   order delivered on2015-05-03 22:11:23   order delivered on2015-05-03 22:11:23   order delivered on2015-05-03 22:11:23

if see output notice first 3 links same , last 4 same.

i need reduce multiple links one.

want display 2 links 1 each.

to that, need use if statement inside while loop. if deliveredtimestamp same don't display otherwise display it. please help.

why not try adding unique deliverytimestamps array , rendering links those?

$timestamps = array(); while($row = mysqli_fetch_array($result)){     if ( !in_array($row['deliverytimestamp'], $timestamps)) {         array_push($timestamps, $row['deliverytimestamp']);     } } foreach ($timestamps $timestamp) {     echo '<p>';     echo '<a href="billinghistory1.php?deliverytimestamp='.$timestamp.'">'.          ' order delivered on' . '</a>' .$timestamp  ;     echo '</p>'; }
