Question

这是我当前的数组

Array
(
    [0] => [10,13],
    [1] => [11,15],
    [2] => [12,7],
    [3] => [1,0],
    [4] => [2,0],
    [5] => [3,0],
    [6] => [4,0],
    [7] => [5,0],
    [8] => [6,0],
    [9] => [7,0],
    [10] => [8,0],
    [11] => [9,0]
);

我想按值（逗号前的值）对此数组进行排序结果应该是这样的：

Array
(    
    [1] => [1,0],
    [2] => [2,0],
    [3] => [3,0],
    [4] => [4,0],
    [5] => [5,0],
    [6] => [6,0],
    [7] => [7,0],
    [8] => [8,0],
    [9] => [9,0],
    [10] => [10,13],
    [11] => [11,15],
    [12] => [12,7]
);

是否可以在PHP中使用？

Answer 1

选项1：如果二维阵列尝试这一个

$data = array();
$data[0] = array(10, 13);
$data[2] = array(11, 15);
$data[3] = array(12, 7);
$data[4] = array(1, 0);
$data[5] = array(2, 0);
$data[6] = array(3, 0);
$data[7] = array(4, 0);
$data[8] = array(5, 0);
$data[9] = array(6, 0);
$data[10] = array(7, 0);
$data[11] = array(8, 0);
$data[12] = array(9, 0);


echo "<pre>";
//print_r($data);
array_multisort($data);
print_r($data);
echo "</pre>";
?>

输出

Array
(
[0] => Array
    (
        [0] => 1
        [1] => 0
    )

[1] => Array
    (
        [0] => 2
        [1] => 0
    )

[2] => Array
    (
        [0] => 3
        [1] => 0
    )

[3] => Array
    (
        [0] => 4
        [1] => 0
    )

[4] => Array
    (
        [0] => 5
        [1] => 0
    )

[5] => Array
    (
        [0] => 6
        [1] => 0
    )

[6] => Array
    (
        [0] => 7
        [1] => 0
    )

[7] => Array
    (
        [0] => 8
        [1] => 0
    )

[8] => Array
    (
        [0] => 9
        [1] => 0
    )

[9] => Array
    (
        [0] => 10
        [1] => 13
    )

[10] => Array
    (
        [0] => 11
        [1] => 15
    )

[11] => Array
    (
        [0] => 12
        [1] => 7
    )
)

选项2：如果一维阵列尝试这一个

$data = array();
$data[0] = "10,13";
$data[2] = "11,15";
$data[3] = "12,7";
$data[4] = "1,0";
$data[5] = "2,0";
$data[6] = "3,0";
$data[7] = "4,0";
$data[8] = "5,0";
$data[9] = "6,0";
$data[10] = "7,0";
$data[11] = "8,0";
$data[12] = "9,0";

echo "<pre>";
//print_r($data);
echo "</pre>";

function dataSort($data){
    $data_temp =array();
    foreach($data as $item){
        $data_temp[] = explode(",",$item);
    }
    array_multisort($data_temp);

    $data =array();
    foreach($data_temp as $item){
        $data[] = $item[0].",".$item[1];
    }
    return $data;
}
$data  = dataSort($data); 
print_r($data);

输出

Array
(
   [0] => 1,0
   [1] => 2,0
   [2] => 3,0
   [3] => 4,0
   [4] => 5,0
   [5] => 6,0
   [6] => 7,0
   [7] => 8,0
   [8] => 9,0
   [9] => 10,13
   [10] => 11,15
   [11] => 12,7
)

Answer 2

试试这个

function mSort($a,$b) {
    if ($a[0] == $b[0]) {
        return 0;
    }
    return ($a[0] < $b[0]) ? -1 : 1;
}

usort($arr, "mSort");

print_r($arr);

Answer 3

你可以使用usort（）函数或任何this list，你附近有什么。例如：

<?php

$array = array (
    array(10,13),
    array(11,15),
    array(12,7),
    array(1,0),
    array(2,0),
    array(3,0),
    array(4,0),
    array(5,0),
    array(6,0),
    array(7,0),
    array(8,0),
    array(9,0)
);

function mySort( $l, $r ) {
   return (( $l[0] == $r[0] ) ? 0 : ($l[0] > $r[0] ? 1 : -1) );
}

usort( $array, 'mySort' );

print_r( $array );

?>

Answer 4

这就是你想要的DEMO

 <?php


$yourArray = array(
    1 => array(
        10,
        13
    ),
    2 => array(
        11,
        15
    ),
    3 => array(
        12,
        7
    ),
    4 => array(
        1,
        0
    ),
    5 => array(
        2,
        0
    ),
    6 => array(
        3,
        0
    ),
    7 => array(
        4,
        0
    ),
    8 => array(
        5,
        0
    ),
    9 => array(
        6,
        0
    ),
    10 => array(
        7,
        0
    ),
    11 => array(
        8,
        0
    ),
    12 => array(
        9,
        0
    )
);

$array = array();

foreach ($yourArray as $key => $row) {
    $array[$key] = $yourArray['value'];
}
array_multisort($array, SORT_DESC, $yourArray);

$yourArray = array_combine(range(1, count($yourArray)), array_values($yourArray));

print_r($yourArray);

?>

Answer 5

你可以尝试

$new = array();
foreach($first_array as $key => $value) {
     $new[$key] = $value;
 }
array_multisort($new, SORT_ASC, $first_array);

Answer 6

您需要访问$value作为对$array中的条目的参考：

private function orderByKey(&$array) {
    ksort($array);
    foreach($array as &$value) {
        if (is_array($value)) {
            $this->orderByKey($value);
        }
    }
}

Answer 7

您可以对此

使用array_multisort（）函数

$arr = array([10,13],[11,15],[12,7],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0],[7,0],[8,0],[9,0]);

        array_multisort($arr);
        var_dump($arr);exit;

Answer 8

由于您正在处理的值是字符串（根据您对我的评论的回复），您需要隔离第一个数值，然后根据它进行排序。（请注意，这不支持相同“第一个数字”的倍数。）

示例：

$a = array("[1,10]", "[2,19]", "[6,13]", "[2,15]", "[4,16]");

$sortable = array();

foreach($a as $subject) {
    $start = strpos($subject, "[");
    $end = strpos($subject, ",");
    $ndx = substr($subject, $start, $end - $start);
    $sortable[$ndx] = $subject;
}

ksort($sortable);

var_dump($sortable);

var_dump将产生：

array(4) {
  ["[1"]=>
  string(6) "[1,10]"
  ["[2"]=>
  string(6) "[2,15]"
  ["[4"]=>
  string(6) "[4,16]"
  ["[6"]=>
  string(6) "[6,13]"
}

Answer 9

你需要使用usort功能：

$a = array([10,13],[11,15],[12,7],[1,0],[2,0],[3,0],[4,0],[5,0],[6,0],[7,0],[8,0],[9,0]);
print_r($a);
usort($a, "cmp");
print_r($a);
?>
