Question

我正在使用PHP lang处理数组。我通过旋转for循环获得了以下输出。现在想把它分成两个不同的数组。任何一个请指导我分成两个不同的数组...喜欢分为[0] = 810和b [0] = 44

以及，我试图在不改变值的情况下对其进行排序，例如排序最大值a [0] = 840＆amp; b [0] = 87

Array
(
    [0] => 810/44
    [1] => 0/280
    [2] => 73/279
    [3] => 0/278
    [4] => 0/277
    [5] => 0/276
    [6] => 840/87
    [7] => 0/275
    [8] => 0/274
    [9] => 0/273
    [10] => 6/271
    [11] => 0/272
    [12] => 0/269
    [13] => 3/267
    [14] => 0/268
    [15] => 3/259
    [16] => 124/108
    [17] => 82/239
    [18] => 221/238
    [19] => 30/160
    [20] => 3/161
    [21] => 65/168
    [22] => 73/169

    [25] => 192/226
    [26] => 209/222
    [27] => 80/223
    [28] => 273/182
    [29] => 79/183
    [30] => 73/184
    [31] => 73/185
    [32] => 6/186
    [33] => 73/187
    [34] => 0/188
    [35] => 48/270
    [36] => 138/190

    [53] => 0/288
    [54] => 73/289
    [55] => 0/290
    [56] => 76/291
    [57] => 76/292

    [62] => 0/297
    [63] => 3/298
    [64] => 0/299
    [65] => 0/300
    [66] => 3/301

Answer 1

怎么样：

$a = $b = array();

foreach ($array as $key => $value) {
    list($a[$key], $b[$key]) = explode('/', $value, 2);
}

编辑：要在之后处理排序，您可以使用：

array_multisort($a, SORT_DESC, SORT_NUMERIC, $b);

Answer 2

  foreach($array1 as $a){

 $a = (string)$a

 $pos = strpos($a, '/')

  $first[] = substr($a, 0, $pos);
 $second[] = substr($a, $pos);

 }

未经测试。。但是你可以尝试这些方面的东西

Answer 3

你可以这样做：

<?php 
$a = array();
$b = array();

$orig_array = array('810/44','0/280');

foreach($orig_array as $orig){
   $values = explode('/',$orig,2);
   $a[]=$values[0];
   $b[]=$values[1];
}
print_r($a);
print_r($b);
/*
Array
(
    [0] => 810
    [1] => 0
)
Array
(
    [0] => 44
    [1] => 280
)    
*/
?>
