PHP loop modulo - php

Question

I would like to make this in a loop:
<div class="global">
<div class="left">1</div>
<div class="right">2</div>
</div>
<div class="global">
<div class="left">3</div>
<div class="right">4</div>
</div>
<div class="global">
<div class="left">5</div>
<div class="right">6</div>
</div>
<div class="global">
<div class="left">7</div>
<div class="right">8</div>
</div>
<div class="global">
<div class="left">9</div>
<div class="right">10</div>
</div>
I know do something link this :
for($i=0;$i<4;$i++){
if($i %2){
$classe='class="right"';
}
else{
$classe='class="left"';
}
echo "<div ".$classe." >".$i."</div>";
}
which result:
<div class="left">1</div>
<div class="right">2</div>
<div class="left">3</div>
<div class="right">4</div>
How Can I integrate the div "global" between ?
Thanks a lot for your help

Answer 1

Iterate two by two:
for ($i = 1; $i <= 4; $i += 2) {
echo '<div class="global">';
echo '<div class="left">' . $i . '</div>'
echo '<div class="right">' . ($i+1) . '</div>'
echo '</div>';
}

Answer 2

You just need a little extra...
echo '<div class="global">'; //start the first global div
for($i=0;$i<4;$i++){
if($i %2){
$classe='class="right"';
}
else{
$classe='class="left"';
}
echo "<div ".$classe." >".$i."</div>";
if($i %2)
{
//after each "right" div, close and open a new global div
echo "</div>\n<div class=\"global\">";
}
}
echo '</div>'; //close the final global div
You can also compact the whole thing a bit:
echo '<div class="global">'; //start the first div
for($i=0;$i<4;$i++)
{
if($i %2)
{
echo "<div class=\"right\" >$i</div>\n</div>\n<div class=\"global\">";
}
else
{
echo "<div class=\"right\" >$i</div>";
}
}
echo '</div>'; //close the final global div

I like printf.
$i=1;
while ($i < 8) {
printf('<div class="global"><div class="left">%d</div><div class="right">%d</div></div>', $i++, $i++);
}
Edit:
Although this doesn't really answer the OP question, and none of the other answers (yet) use modulus as per the question title. So, here is another far more ugly way :)
echo '<div class="global">';
for($i=0;$i<8;$i++){
if ($i %2) {
$classe='right';
$sep='</div><div class="global">';
}
else{
$classe='left';
$sep='';
}
printf('<div class="%s">%d</div>%s', $classe, $i+1, $i<7?$sep:'');
}
echo '</div>';

Answer 4

This code works :
echo '<div class="global">'; //start the first global div
for($i=0;$i<7;$i++){
if($i %2){
$classe='class="right"';
}
else{
$classe='class="left"';
}
echo "<div ".$classe." >".$i."</div>";
if($i %2)
{
//after each "right" div, close and open a new global div
echo "</div>\n<div class=\"global\">";
}
}
echo '</div>';
