How to output a value on every third result of a foreach statement in php?

Question

I have a foreach statement in my app that echos a list of my database results:

Answer 1

<?php

foreach ($featured_projects as $i => $fp) {
    echo '<div class="result' . ($i % 3 === 0 ? ' third' : '') . '">';
    echo $fp['project_name'];
    echo '</div>';
}
?>

Answer 2

add a counter in this loop and check if counter equals three and apply class.

Answer 3

This is the working version, sorry for my prev version:

<?php
$featured_projects[0]['project_name'] = "pippo";
$featured_projects[1]['project_name'] = "pippo2";
$featured_projects[2]['project_name'] = "pippo3";

$class[0] = "class1";
$class[1] = "class2";

$i=0;
foreach($featured_projects as $fp) {
  $i++;
  if ($i == 3) {
    $c = $class[1];
    $i=0;
  } else {
    $c = $class[0];
  }
  echo "<div class=\"$c\">";
  echo $fp['project_name'];
  echo "</div>\n";
}
?>

Produces:

<div class="class1">pippo</div>
<div class="class1">pippo2</div>
<div class="class2">pippo3</div>

Answer 4

You can add a counter in loop ...try the following...

 <?php 
 $i = 0; 
 foreach($featured_projects as $fp) {
 $i = ++$i;
 if(($i%3) == 0)
 {
  $class1 = 'test1';
 }
 else
 {
 $class1 = 'test2';
 }
       echo '<div class="'.$class1.'">';
       echo $fp['project_name'];
       echo '</div>';
 }
 ?>

Using a counter and modulo operator this is easy to implement
