Question

说我有这3个阵列：

Product(milk,candy,chocolate)
Colors(white,red,black)
Rating(8,7,9)

如何创建一个循环来绑定这些数组，以便在每个循环中得到3个变量：$product $color $rating

因此，通过示例，我将输出如下：

牛奶白色且评分 8 / 10

糖果红色且评分 7 / 10

巧克力 黑色且评分 9 / 10

由于

Answer 1

E.g。使用SPL的MultipleIterator

<?php
$Product=array('milk','candy','chocolate');
$Colors=array('white','red','black');
$Rating=array(8,7,9);

$it = new MultipleIterator;
$it->attachIterator(new ArrayIterator($Product));
$it->attachIterator(new ArrayIterator($Colors));
$it->attachIterator(new ArrayIterator($Rating));

foreach( $it as $e ) {
  echo join(' - ', $e), "\n";
}

打印

milk - white - 8
candy - red - 7
chocolate - black - 9

Answer 2

我不知道我是否做对了。但是你想要这样的东西吗？

$products = array("milk", "candy", "chocolate");
$colors = array("white", "red", "black");
$ratings = array(8, 7, 9);

 for($i = 0; $i < sizeof($products); $i++) {
    $product = $products[$i];
    $color = $colors[$i];
    $rating = $ratings[$i];

    echo $product . ' is ' . $color . ' and has a rating of ' . $rating . '/10 <br/>';
 }

输出将是：

milk is white and has the rating of 8/10
candy is red and has the rating of 7/10
chocolate is black and has the rating of 9/10
