Continuous array key in foreach loop outputs
0
I have two arrays (say, $arrayA and $arrayB) with numerous values in them.
I would like to fill a list of 8 divs with these values using a foreach loop which has has just 4 divs in it, with each div increasing an incremental key from their respective array.
The following should hopefully illustrate:
foreach ($values as $value) {
echo
'<div class="type-a">' . $arrayA[i] . '</div>
<div class="type-b">' . $arrayB[i] . '</div>
<div class="type-a">' . $arrayA[i+1] . '</div>
<div class="type-b">' . $arrayB[i+1] . '</div>';
}
<div class="type-a"> A1 </div>
<div class="type-b"> B1 </div>
<div class="type-a"> A2 </div>
<div class="type-b"> B2 </div>
<div class="type-a"> A3 </div>
<div class="type-b"> B3 </div>
<div class="type-a"> A4 </div>
<div class="type-b"> B4 </div>
Any suggestions would be great!

you can try to do loop based on len(array), then i:0 i+=2, then get the first and second array from a and b

After your comment regarding differences in length, you can count the size of each to determine which is bigger and then iterate over that one as the main array:
<?php
# Make sure each value is an array
$arrayA = (empty($arrayA))? : array_values($arrayA);
$arrayB = (empty($arrayB))? : array_values($arrayB);
# Determine which array is longer
if(count($arrayA) >= count($arrayB)) {
$arr_L = $arrayA;
$arr_S = $arrayB;
}
else {
$arr_L = $arrayB;
$arr_S = $arrayA;
}
# Iterate over the larger array
foreach($arr_L as $key => $value): ?>
<!-- Just echo the value here because you are iterating this array -->
<div class="type-a"> <?php echo $value ?> </div>
<!-- Use the current key from this array to fetch the value from the B array -->
<div class="type-b"> <?php echo $arr_S[$key] ?> </div>
<?php endforeach ?>

In actuality the arrays are not equal, in some cases ArrayA may have more values, and in other ArrayB may have more

You have to determine which array is larger and iterate over that one. See edit.
