如何在php中嵌套的foreach循环中解决重置变量的问题

Question

我有已转换为数组的字符串，但想在列表中显示它们。如何重置循环以避免重复？我试过将变量设置为空白，通常用于单个foreach语句$SEAT = "1A,4A";$NAME = "John Doe, Jane Doe";$PHONE_NUMBER = "123456856,1235668";$SEAT_USSD_STRING_VALUE = explode(",", $SEAT);$NAME_USSD_STRING_VALUE = explode(",", $NAME);$PHONE_USSD_STRING_VALUE = explode(",", $PHONE_NUMBER);$seat_value = "";foreach ($SEAT_USSD_STRING_VALUE as $seat_key => $seat_value) {    $name_value = "";    foreach ($NAME_USSD_STRING_VALUE as $name_key => $name_value) {        $phone_number_value = "";        foreach ($PHONE_USSD_STRING_VALUE as $phone_number_key => $phone_number_value) {            echo "$seat_value: $name_value - $phone_number_value<br/>";        }    }}我期望得到1A: John Doe - 123456784A: Jane Doe - 87654321但是我得到这个1A: John Doe - 123456781A: John Doe - 876543211A: Jane Doe - 123456781A: Jane Doe - 876543214A: John Doe - 123456784A: John Doe - 876543214A: Jane Doe - 123456784A: Jane Doe - 87654321

Answer 1

您只需要使用第$seat_key一个可访问的键（）foreach

用这个foreach代替你所有的foreach

foreach ($SEAT_USSD_STRING_VALUE as $seat_key => $seat_value) {

        echo "$seat_value: $NAME_USSD_STRING_VALUE[$seat_key] - $PHONE_USSD_STRING_VALUE[$seat_key]<br/>";

}
