$color_arr = array("red","green","white");
$list_arr_two = array("a","b","c","d","e","f");
for ex -: a = red;
b = green;
c = white;
d = red;
e = green;
f = white;
一旦所有陣列顏色重復完成，我只需要重復顏色。

請嘗試以下代碼：
<?php
$color_arr = array("red","green","white");
$list_arr_two = array("a","b","c","d","e","f","sd");
$i=0;
$color_length = count($color_arr) -1 ;
foreach($list_arr_two as $key=>$val)
{
echo $colorCode = $color_arr[$i];
echo "<br/>";
$i ;
if($i > $color_length)
{
$i =0;
}
}
?>

帶有條件的簡單回圈以重置索引以使用顏色陣列。
<?php
$c = ["red","green","white"];
$l = ["a","b","c","d","e","f"];
$r = [];
$j = 0;
for ($i = 0; $i < count($l); $i ) {
$r[$l[$i]] = $j === count($c) ? $c[$j = 0] : $c[$j];
$j ;
}
print_r($r);
/* output
Array
(
[a] => red
[b] => green
[c] => white
[d] => red
[e] => green
[f] => white
)
*/

使用此自定義函式獲取結果
$color_arr = array("red","green","white");
$list_arr_two = array("a","b","c","d","e","f");
print_r(ArrayMap($color_arr,$list_arr_two));
function ArrayMap($color_arr,$keyarray){
$newarr=array();
$total_array = count($color_arr);
foreach ($keyarray as $key => $value) {
$newarr[$value] = $color_arr[$key%$total_array];
}
return $newarr;
}
