PHP循环模数

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>';
}
