我正在尝试实施一种解决方案，以找出页数最多的MONTH。有谁知道如何循环访问此JSON数组，以便我可以提取每个月的$ total（$ total1，$ total2，$ total3，... $ total12），然后将它们添加到数组中，然后找到最大数量（意味着页面数最多的月份）？
这是到目前为止我一个月以来一直在尝试的方法：
foreach($my_array as $value){
foreach ($value->all_books as $all_book) {
foreach ($all_book->number_of_pages as $num_page) {
if ($num_page->number_of_books && $num_page->pages) {
$total += $num_page->number_of_books * $num_page->pages;
}
}
}
}
您可以像这样计算月份的页数：
$monthWisePageCount = array();
foreach($my_array as $value){
$month = date('M', strtotime($value->datetime_status));
if(!in_array($month, array_keys($monthWisePageCount))){
$monthWisePageCount[$month]['count'] = 0;
$monthWisePageCount[$month]['month'] = date('F', strtotime($value->datetime_status));
}
foreach ($value->all_books as $all_book) {
foreach ($all_book->number_of_pages as $num_page) {
if ($num_page->number_of_books && $num_page->pages) {
$monthWisePageCount[$month]['count'] += $num_page->number_of_books * $num_page->pages;
}
}
}
}
print_r($monthWisePageCount);
结果将如下所示
Array
(
[Mar] => Array
(
[count] => 900
[month] => March
)
[Dec] => Array
(
[count] => 558
[month] => December
)
[Oct] => Array
(
[count] => 280
[month] => October
)
)
您可以找到这样的最大物品：
$largestKey = '';
$largestCount = 0 ;
foreach($monthWisePageCount as $key => $item){
if($item['count'] > $largestCount ) {
$largestCount = $item['count'];
$largestKey = $key;
}
}
$monthWithLargestPageCount = $monthWisePageCount[$largestKey];
print_r($monthWithLargestPageCount);
结果将是这样
Array ( [count] => 900 [month] => March )
