如何打印出两个关联数组并使用循环来爆炸第二个数组值？问题是爆炸

数组属性将限制为3个值，值将限制为4个。

[attributes] => Array ( [0] => Array ( [attribute] => Colour ) [1] => Array ( [attribute] => Size ) )
[values] => Array ( [0] => Array ( [value] => Red,Green,Blue ) [1] => Array ( [value] => Large,Medium,Small ) )

如果有帮助我可以将值的密钥保存为属性名称：

Array ( [colour] => Red,Green,Blue )

代码：

foreach ($attributes as $k => $v)
{
    echo "<b>" .$v['attribute'] ."</b>"."<br>";

    foreach ($values as $val)
    {

        $value = $val['value'];
        $expld = explode(",", $value);
        foreach ($expld as $explval)
        {
            $qryString = array( 'search' => $search,
                                'attr' => $explval
                              );

            echo anchor('products/item_search?'. http_build_query($qryString), $explval) ."<br>";
        }
    }
}

Answer 1

 for ($i = 0; $i<count($attributes); $i++)
  {
    echo "<b>" .$attributes[$i]['attribute'] ."</b>"."<br>";


        $expld = explode(",", $values[$i]['value']);
        foreach ($expld as $explval)
        {
            $qryString = array( 'search' => $search,
                'attr' => $explval
            );

            echo anchor('products/item_search?'. http_build_query($qryString),$explval) ."<br>";
        }

}

你不想遍历内部循环中的所有$values，你只想爆炸与当前属性具有相同索引的那个并循环遍历那些。

foreach ($attributes as $index => $v) {
    echo "<b>{$v['attribute']}</b><br>";
    foreach (explode(',', $values[$index]['value']) as $explval) {
        $qryString = array( 'search' => $search,
                            'attr' => $explval
                          );
        echo anchor('products/item_search?'. http_build_query($qryString), $explval) ."<br>";
    }
}
