如何格式化时间12:00:00或12:00：上午12:00至上午12:00？

Question

我正在使用strtotime（） 其工作正常$ time = '12：00：00'; 但

$time = '12:00:am'; 
echo date('h:i A ', strtotime($time)); 

交回下午4:00，但我想输出是12:00 AM

此功能可以帮助你。它需要一段时间，比如你的格式“12:00:00或12:00：am”，并输出它的需求，就像你这样的“上午12:00”。

function convert_time($the_time){ 
    $time_arr = explode(":",$the_time); 
    if($time_arr[2] != "am" || $time_arr[2] != "pm"){ 
     if($time_arr[0] >= "0" && $time_arr[0] <= 12){ 
      if($time_arr[0] == 12 && $time_arr[1] > 00){ 
       $time_arr[2] = "pm"; 
      } else { 
       $time_arr[2] = "am"; 
      } 
     } else { 
      $time_arr[2] = "pm"; 
     } 
     $new_time = $time_arr[0].":".$time_arr[1]." ".strtoupper($time_arr[2]); 
     return $new_time; 
    } 
    $new_time = $time_arr[0].":".$time_arr[1]." ".strtoupper($time_arr[2]); 
    return $new_time; 
} 

$time = '12:00:am'; 
echo convert_time($time);
