PHP Foreach循环 - 为什么返回相同的结果？

Question

这一次反复出现同样的价值。它调用三个依赖于数组中变量的函数 - 我缺少什么？

$arr = array('LGW','LHR');


foreach ($arr as $airportcode) {


$result1 = fhrxml($airportcode);
$result2 = parkingquotexml($airportcode);
$result3 = holidayextrasxml($airportcode);

$result4 = array_merge($result1, $result2, $result3);


sort($result4, SORT_NUMERIC);
$result5 = reset($result4); // First Element's Value


$price01 = array_splice(explode('<br>',$result5),0,1);  
$price = implode('<br>',$price01);

$name01 = array_splice(explode('<br>',$result5),1,2);  
$name = implode('<br>',$name01);

echo $name;

}
