我有几个这样的数组。

Array

我正在尝试按邮政编码排序，然后按州排序，然后按县排序。我遇到的问题是让邮政编码按字符串中第一个邮政编码的升序显示。所以顺序是

64055, 64056, ...

89002, 89009, ...

91381, 91384, ...

94530, 94804, ...

这是我目前的结果。

WA,TL-WA-150,150,King, Snohomish,98004, 98005, 98006, 98007, 98008, 98011, 98012, 98102, 98105, 98112, 98136, 98025, 98033, 98034, 98083

我的问题是如何让邮政编码按升序排序？

我现在正在使用它进行排序。

sortDataSet($difarray, 'zipcodes', SORT_DESC, SORT_NUMERIC, 'state', SORT_ASC, SORT_STRING,'counties', SORT_DESC, SORT_STRING); 

function sortDataSet(&$dataSet) {
$args = func_get_args();
$callString = 'array_multisort(';
$usedColumns = array();
for($i = 1, $count = count($args); $i < $count; ++$i) {
    switch(gettype($args[$i])) {
        case 'string':
            $callString .= '$dataSet[\''.$args[$i].'\'], ';
            array_push($usedColumns, $args[$i]);
            break;
        case 'integer':
            $callString .= $args[$i].', ';
            break;
        default:
            throw new Exception('expected string or integer, given '.gettype($args[$i]));
    }
}
foreach($dataSet as $column => $array) {
    if(in_array($column, $usedColumns)) continue;
    $callString .= '$dataSet[\''.$column.'\'], ';
}
eval(substr($callString, 0, -2).');');
}

最佳答案

所以我假设您有一个包含三个数组的数组，即州、县和邮政编码。 我还假设您的包含这些数组的数组称为 $data，因此请在此处替换您的数组名称。

我相信您的原始数组是这样设置的。

$data = array(
'state' => array
    (
     'WA',
     'CA',
     'CA',
     'NV',
     'MO',
     'CA',
     'CA',
     'CA',
     'CT',
     'FL',
     'FL',
     'ID',
     'ID',
     'IN',
     'MN',
     'MN',
     'NE',
     'NY',
     'TX',
     'TX',
     'WI'
),

'counties' => array
(
     'King, Snohomish',
     'Contra Costa',
     'Los Angeles',
     'Clark',
     'Jackson',
     'Tulare',
     'Sacramento',
     'Riverside',
     'New Haven',
     'Pinellas',
     'Lake',
     'Canyon',
     'Ada',
     'Tippecanoe, White, Carroll',
     'Crow Wing, Cass',
     'Blue Earth',
     'Douglas',
     'Rockland',
     'Webb',
     'Harris',
     'Waukesha, Milwaukee, Washington'


),

'zipcodes' => array
(
    '98004, 98005, 98006, 98007, 98008, 98011, 98012, 98102, 98105, 98112, 98136, 98025, 98033, 98034, 98083',
    '94530, 94804, 94805, 94803, 94806, 94564, 94547',
    '91381, 91384, 91354, 91355, 91321, 91387, 91351, 91390, 91350',
    '89002, 89009, 89011, 89012, 89014, 89015, 89016, 89128, 89048, 89052, 89053, 89060, 89061, 89074, 94588, 89102, 89105, 89108, 89109, 89111, 89112',
    '64055, 64056, 64057, 64052, 64064, 64050, 64058, 64014, 64015, 64029, 64063, 64081, 64082, 64086, 64133',
    '','','','','','','','','','','','','','','',''
));

所以，这是我的解决方案:

//make our own array with state, counties, and zips living together.
$sortData=array();
foreach($data['state'] as $key =>$thisState){

//first sort the zipcode string itself.
$zipcodeArray = explode(", ",$data['zipcodes'][$key]);
sort($zipcodeArray,SORT_NUMERIC);
$zipcodeString = implode(", ",$zipcodeArray);

$pusharray=array('state'=>$thisState,'county'=>$data['counties'][$key],'zipcode'=>$zipcodeString);
array_push($sortData,$pusharray);

}//foreach

$states=array();
$counties=array();
$zipcodes=array();
foreach ($sortData as $key => $row) {

    $states[$key] = $row['state'];
    $counties[$key] = $row['county'];
    $zipcodes[$key] = $row['zipcode'];

}//
$index=0;

array_multisort($zipcodes, SORT_NUMERIC, SORT_ASC, $states, SORT_ASC, $counties,  SORT_ASC, $sortData);


function blank($var)
{
 if (empty($var['zipcode'])){return true;}else{return false;}
}

function zipcodeString($var)
{
 if (!(empty($var['zipcode']))){return true;}else{return false;}
}


$noZipcodeChunk=(array_filter($sortData, "blank"));
$zipcodeChunk=(array_filter($sortData, "zipcodeString"));
$finalArray = array_merge($zipcodeChunk,$noZipcodeChunk);



foreach ($finalArray as $datum){
    echo $datum['state'].' '.$datum['county'].' '.$datum['zipcode'].'<br>';

}

我认为这就是您要寻找的:
