Question

我正在尝试构建一个多维数组。

public function saveRateTemplateData($RateTemplateInfo)
{
    $RateTemplateID = $RateTemplateInfo['id'];
    $Zones = $RateTemplateInfo['premium_zones'];
    //$ZoneZipCodeIDs[] = array();
    for ($n = 1; $n <= $RateTemplateInfo['premium_zones']; $n++) {
        $ZoneNum = 'zone' . $n;
        $ZipCodeArray = explode(",",$_POST[$ZoneNum]);
        $ZipCodeIDs=array();
        foreach ($ZipCodeArray as $v) {
            $v = intval(trim($v));
            if (strlen($v) == 5) {
                array_push($ZipCodeIDs, $this->addZipCode($v));  
            } else {
                echo "it isnt 5";
            }
        }
    }
}

所以我想做的是创建一个数组的数组。所以这就是它应该看起来的样子

Array
(
  [1] => Array
    (
        [0] => 34
        [1] => 31
        [2] => 23
    )

  [2] => Array
    (
        [0] => 18
        [1] => 4
        [2] => 35
        [3] => 1
    )
)

我尝试了很多不起作用的方法基本上我想要这种格式VarName [ZoneNumbers] [ZipCodeID]

所以我可以稍后循环播放它。所以我可以像这样打印$ VarName [$ n]然后所有zipcodeID的数组将打印为区号1，在这种情况下它将打印34,31,23

public function saveRateTemplateData($RateTemplateInfo)
{
    $RateTemplateID = $RateTemplateInfo['id'];
    $zones = array(); // you weren't using this so I'll use it to hold the data

    for ($n = 1; $n <= $RateTemplateInfo['premium_zones']; $n++) {
        $ZoneNum = 'zone' . $n;

        // create an array under the zone number for holding the IDs
        $zones[$n] = array();

        $ZipCodeArray = explode(",",$_POST[$ZoneNum]);
        foreach ($ZipCodeArray as $v) {
            $v = (int) trim($v);
            if (strlen($v) == 5) {
                $zones[$n][] = $this->addZipCode($v);
            } else {
                // use exceptions for exceptional circumstances
                throw new RuntimeException(sprintf('Invalid zone ID "%s"', $v));
            }
        }
    }

    return $zones;
}
