how do I use a function to cross merge two arrays?
wrote a method that I don't know if it is what the landlord wants, as follows:
function jiaochaArray($arr1, $arr2)
{
$arr1 = array_values($arr1);
$arr2 = array_values($arr2);
$count = max(count($arr1), count($arr2));
$arr = array();
for ($i = 0; $i < $count; $iPP) {
if ($i < count($arr1)) $arr[] = $arr1[$i];
if ($i < count($arr2)) $arr[] = $arr2[$i];
}
return $arr;
}function mergeArr(arr1, arr2) {
let arr = arr1.slice(0)
arr2.forEach((item, index) => {
arr.splice(2 * (index + 1) - 1, 0, item)
})
return arr
}array_intersect ()
If thesystem is ready-made, don't write it yourself
