我有两个数组，一个是小时数组列表，第二个是我的结果数组。我必须使用24小时元素填充$current_play数组。
首先，我将小时数组值搜索到具有$watch_hour值的第二个数组。如果值不匹配，则不填充零值，并添加零值的数组元素。
第一个数组：
$hoursArray=
['0','1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23'];
第二阵列：
$result = array(
array(
"code" => "BA",
"name" => "BARCA",
"current_play" => array(
array(
"whours" => "20",
"value" => "6"
),
array(
"whours" => "5",
"value" => "6"
),
array(
"whours" => "6",
"value" => "6"
),
array(
"whours" => "8",
"value" => "6"
),
array(
"whours" => "9",
"value" => "6"
)
)
)
);
我正在尝试下面的代码，但它不起作用;
for($i = 0; $i < count ( $hoursArray ); $i ++) {
foreach ($result as $t){
if($t['watch_hour'] == $hoursArray[$i]){
$result[$v['code']]['cplay'][] = array('whours'=> $hoursArray[$i],'value' => $v['value']);
} else{
$result[$v['code']]['cplay'][] = array('whours'=> $hoursArray[$i],'value' => "0");
}
}
}
必需的数组将是：
Array
(
[0] => Array
(
[code] => BA
[name] => BARCA
[current_play] => Array
(
[0] => Array
(
[whour] => 0
[value] => 0
)
[1] => Array
(
[whour] => 1
[value] => 0
)
[2] => Array
(
[whour] => 2
[value] => 0
)
[3] => Array
(
[whour] => 3
[value] => 0
)
[4] => Array
(
[whour] => 4
[value] => 6
)
[5] => Array
(
[whour] => 5
[value] => 6
)
[6] => Array
(
[whour] => 6
[value] => 6
)
and so on for each hours element....
)
)
)

我试图解决它的方法是使用array_column()将播放的小时数提取到索引数组中。然后每小时检查是否有值，如果没有找到则将其添加。然后取出结果并将其放回主数组（已排序）...
$currentPlay = array_column($result[0]['current_play'], null, "watch_hour" );
foreach ( $hoursArray as $hour ) {
if ( isset($currentPlay[$hour]) === false ) {
$currentPlay[$hour] = array(
"watch_hour" => "$hour",
"value" => "0"
);
}
}
sort($currentPlay);
$result[0]['current_play'] = $currentPlay;
print_r($result);
输出是......
Array
(
[0] => Array
(
[code] => CA
[name] => Canada
[current_play] => Array
(
[0] => Array
(
[watch_hour] => 0
[value] => 0
)
[1] => Array
(
[watch_hour] => 1
[value] => 0
)
[2] => Array
(
[watch_hour] => 2
[value] => 0
)
[3] => Array
(
[watch_hour] => 3
[value] => 0
)
[4] => Array
(
[watch_hour] => 4
[value] => 0
)
[5] => Array
(
[watch_hour] => 5
[value] => 6
)
[6] => Array
(
[watch_hour] => 6
[value] => 6
)
[7] => Array
(
[watch_hour] => 7
[value] => 0
)
[8] => Array
(
[watch_hour] => 8
[value] => 6
)
[9] => Array
(
[watch_hour] => 9
[value] => 6
)
[10] => Array
(
[watch_hour] => 10
[value] => 0
)
[11] => Array
(
[watch_hour] => 11
[value] => 0
)
[12] => Array
(
[watch_hour] => 12
[value] => 0
)
[13] => Array
(
[watch_hour] => 13
[value] => 0
)
[14] => Array
(
[watch_hour] => 14
[value] => 0
)
[15] => Array
(
[watch_hour] => 15
[value] => 0
)
[16] => Array
(
[watch_hour] => 16
[value] => 0
)
[17] => Array
(
[watch_hour] => 17
[value] => 0
)
[18] => Array
(
[watch_hour] => 18
[value] => 0
)
[19] => Array
(
[watch_hour] => 19
[value] => 0
)
[20] => Array
(
[watch_hour] => 20
[value] => 6
)
[21] => Array
(
[watch_hour] => 21
[value] => 0
)
[22] => Array
(
[watch_hour] => 22
[value] => 0
)
[23] => Array
(
[watch_hour] => 23
[value] => 0
)
)
)
)
<强>更新 为每个国家做这件事......
foreach ( $result as $key => $country ) {
// $currentPlay = array_column($country['current_play'], null, "watch_hour" );
$currentPlay = array();
foreach ( $country['current_play'] as $item ) {
$currentPlay[$item["watch_hour"]] = $item;
}
foreach ( $hoursArray as $hour ) {
if ( isset($currentPlay[$hour]) === false ) {
$currentPlay[$hour] = array(
"watch_hour" => "$hour",
"value" => "0"
);
}
}
sort($currentPlay);
$result[$key]['current_play'] = $currentPlay;
}

试试这个：
$currebt_hours = array_column($result[0]['current_play'], 'watch_hour');
$arrdiff = array_diff($hoursArray, $currebt_hours);
foreach ($arrdiff as $value) {
$entry = array();
$entry[watch_hour]=$value;
$entry[value]=0;
$result[0][current_play][]=$entry;
}
