如何将此数组存储到多个变量？

Question

嗨，我如何将这个数组存储到两个不同的变量而不是echo？

$countries = array();
foreach ($my_data as $node)
{
    foreach($node->getElementsByTagName('a') as $href)
    {
        preg_match('/([0-9\.\%]+)/',$node->nodeValue, $match);
        $countries[trim($href->nodeValue)] = $match[0]; 
    }
}    

foreach ($countries as $country => $percent) echo str_replace("Â","",(strip_tags($country))) . ' - ' . str_replace("Â","",(strip_tags($percent)));

这将输出

USA - 75%
UK - 65%
AU - 56%
UAE - 52%

我正在寻找的是我需要将这个数组存储在多个变量中

$datac = USA,UK,AU,UAE

$datap = 75%,65%,56%,52%

那样的想法吗？

Answer 1

$datac = array();
$datap = array();

foreach($countries as $country => $percent) {
    $datac[] = str_replace("Â","",(strip_tags($country)));
    $datap[] = str_replace("Â","",(strip_tags($percent)));
}

如果希望将它们作为字符串，则可以执行以下操作：

$datac = implode(',', $datac);
$datap = implode(',', $datap);
