有一个PHP数组，我想按日期和时间对其进行排序，但是事情没有按预期进行。如何根据递增的日期和时间排序此数组？
原始数组：

PHP代码：
按时间排序
usort($Ledgers, function( $a, $b ) {return strtotime($a["Create_time"]) - strtotime($b["Create_time"]);});
明智地排序日期
usort($Ledgers, function( $a, $b ) {return strtotime($a["Create_date"]) - strtotime($b["Create_date"]);});
答案 0 :(得分：0)
您只需先连接日期和时间
usort($Ledgers, function( $a, $b ) {
$create_a = strtotime($a["Create_date"].$a["Create_time"]);
$create_b = strtotime($b["Create_date"].$b["Create_time"]);
return $create_a - $create_b;
});
并使用usort函数一次。
另一个解决方案是使用strcmp对字符串进行排序
usort($Ledgers, function ($a, $b) {
return strcmp($a['Create_date'].$a['Create_time'], $b['Create_date'].$b['Create_time']);
});
