Question

I have a foreach in which I have three different arrays. I want to put the value – when running the foreach – in the different arrays every third time (look example below for better explanation).

Ex: arr = blue, red, green, yellow, brown

arr1 = blue, yellow arr2 = red, brown arr3 = green

I have this code (but dont work because the modulus doesn’t come down to the last if statement more then the first execution of the if).

$count = 0;
foreach($values as $value){
    if($count%2){
        $arrSecond[] = $value[img][url];
    }
    else if($count%3){
        $arrThird[] = $value[img][url];
    }
    else {
        $arrFirst[] = $value[img][url];
    }
    $count++;
}

How can I solve this?

You need to be using modulus 3 the whole time only with different offsets:

foreach($values as $value){
    $mod = $count%3;
    if($mod == 1){
        $arrSecond[] = $value['img']['url'];
    }
    // elseif, not else if!
    elseif($mod == 2){
        $arrThird[] = $value['img']['url'];
    }
    else {
        $arrFirst[] = $value['img']['url'];
    }
    $count++;
}
