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。

我的问题是如何让邮政编码按升序排序？

我现在正在用它来排序。

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).');');
}

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。 我还假设包含这些数组的数组称为 

$data
，因此请替换其中的数组名称。

我相信你原来的数组是这样设置的。

$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>';

}

我认为这就是您正在寻找的：

MO Jackson 64014, 64015, 64029, 64050, 64052, 64055, 64056, 64057, 64058, 64063, 64064, 64081, 64082, 64086, 64133

这是可能对您有帮助的代码

$array = array(
    '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',
    ),
    'state' => array(
        'WA', 'CA', 'FL'
    ),
    'counties' => array(
        'Lake', 'King, Snohomish'
    )
);

foreach ($array as $key => $value) {
    sort($array[$key]); // sort array from lowest to highest http://nz.php.net/manual/en/function.sort.php
    // or reverse sort using arsort http://nz.php.net/manual/en/function.arsort.php
}

您可以使用 $key 来决定使用哪个排序函数

foreach ($array as $key => $value) {
    if ($key == 'zipcodes') {
        sort($array[$key]);
    } else {
        arsort($array[$key]);
    }
}
