按衣服尺寸排序数组(多维数组) - sort array on clothing sizes (multidimensional array)

我的数组是这样的:

    Array
     (
     [0] => Array
    (
        [id] => 613
        [kleur] => royalblauw/wit
        [maat] =>  maat XL
        [voorraad] => 100
        [sort] => 0
        [prijs] => 4.1320
    )
[1] => Array
    (
        [id] => 614
        [kleur] => royalblauw/wit
        [maat] =>  maat XXL
        [voorraad] => 100
        [sort] => 1
        [prijs] => 4.1320
    )
[2] => Array
    (
        [id] => 620
        [kleur] => zwart/wit
        [maat] =>  maat XL
        [voorraad] => 100
        [sort] => 2
        [prijs] => 4.1320
    ) 
       etc.etc.

我想要的是排序数组的'maat'(大小)。正如您所看到的，有多个条目具有相同的"maat"。

我已经试了几个小时了，但仍然没有一个好的结果。当然，我也一直在关注Stackoverflow。这是我到目前为止所拥有的。

功能:

function cmp($a, $b)
{
$sizes = array(
"116" => 0,
"128" => 1,
"140" => 2,
"152" => 3,
"164" => 4,
"XXS" => 5,
"XS" => 6,
"S" => 7,
"M" => 8,
"L" => 9,
"XL" => 10,
"XXL" => 11,
"XXXL" => 12,
"XXXXL" => 13,
"XXXXXL" => 14
);
$asize = $sizes[$a];
$bsize = $sizes[$b];
if ($asize == $bsize) {
    return 0;
}
return ($asize > $bsize) ? 1 : -1;
}
function aasort (&$array, $key) {
    $sorter=array();
    $ret=array();
    reset($array);
    foreach ($array as $ii => $va) {
        $sorter[$ii]=$va[$key];
    }
    uasort($sorter, "cmp");
    foreach ($sorter as $ii => $va) {
        $ret[$ii]=$array[$ii];
    }
    $array=$ret;
}

和调用函数aasort:

aasort($maatkleur_array,"maat");

你能帮帮我吗?

您想对数组的数组进行排序。父数组没有(命名的)键。ussort保留了你不需要的键，所以用ussort代替:

error_reporting(E_ALL);
ini_set('display_errors','on');
function cmp($a, $b)
{
    $sizes = array('s'=>0,'m'=>'1','l'=>2,'xl'=>3);
    if ($sizes[$a['maat']] == $sizes[$b['maat']]) {
        return 0;
    }
    return ($sizes[$a['maat']] < $sizes[$b['maat']]) ? -1 : 1;
}

$input = array(
array('id'=>1,'kleur'=>'blauw','maat'=>'xl'),
array('id'=>2,'kleur'=>'blauw','maat'=>'m'),
array('id'=>1,'kleur'=>'blauw','maat'=>'s'),
array('id'=>2,'kleur'=>'blauw','maat'=>'m'),
array('id'=>3,'kleur'=>'blauw','maat'=>'l')
);
usort($input, "cmp");
print_r($input);

我已经稍微改变了你的cmp功能，以实现你所期望的…

$sort = array();
// $arrayData is your main array 
foreach($arrayData as $key => $value)
{
   $sort[$key] = cmp(strtoupper(str_replace('maat ', '', $value['maat'])));
}
array_multisort($sort, SORT_ASC, $arrayData);  
function cmp($a)
{
$sizes = array(
"116" => 0,
"128" => 1,
"140" => 2,
"152" => 3,
"164" => 4,
"XXS" => 5,
"XS" => 6,
"S" => 7,
"M" => 8,
"L" => 9,
"XL" => 10,
"XXL" => 11,
"XXXL" => 12,
"XXXXL" => 13,
"XXXXXL" => 14
);

return $sizes[$a];
}

排序基于CMP函数的返回值。$arrayData将根据maat的大小对数组进行排序

EDIT:

使用这个回调。

<?php
function usort_callback($a, $b) {
        $sizes = array(
            "116" => 0,
            "128" => 1,
            "140" => 2,
            "152" => 3,
            "164" => 4,
            "XXS" => 5,
            "XS" => 6,
            "S" => 7,
            "M" => 8,
            "L" => 9,
            "XL" => 10,
            "XXL" => 11,
            "XXXL" => 12,
            "XXXXL" => 13,
            "XXXXXL" => 14
        );
        $value1 = $sizes[trim(str_replace('maat', '', $a['maat']))];
        $value2 = $sizes[trim(str_replace('maat', '', $b['maat']))];
        return ($value1 < $value2) ? -1 : 1;
    }
?>

原始文章:

试试usort():

<?php
    function usort_callback($a, $b) {
        return strcmp($a['maat'], $b['maat']);
    }
    usort($array, "usort_callback");
?>

现在你的数组应该按照键"maat"

进行排序
