Question

在文字中，我有很多时间码，然后我想将小时改为另一个时区（+6），例如：

00:15 =＆gt; 6时15分

01:00 =＆gt; 07:00

......等等。我试过这个：

$result = str_replace(
  array("00:","01:","02:","03:","04:","05:","06:","07:","08:","09:","10:","11:","12:","13:","14:","15:","16:","17:","18:","19:","20:","21:","22:","23:"),
    array("06:","07:","08:","09:","10:","11:","12:","13:","14:","15:","16:","17:","18:","19:","20:","21:","22:","23:","00:","01:","02:","03:","04:", "05:"),
    $text
);
 echo $result;

但是18：将替换为04：因为php替换18：到22：然后继续替换22：到04：

如何解决这个问题，谢谢。

Answer 1

我认为最好是使用时间戳格式，添加时间并从中获取新的时间。

Answer 2

$time = array("00:","01:","02:","03:","04:","05:","06:","07:","08:","09:","10:","11:","12:","13:","14:","15:","16:","17:","18:","19:","20:","21:","22:","23:");

$required_time = array();
    
foreach($time as $t){
    $hour = $t."00"; // 00 appending 0 minites
    $hours_plus = 6; // adding 6 hours
    $required_time[] = date('H:', strtotime($hour)+($hours_plus*60*60));
}
echo "<pre>";
    print_r($required_time);
    echo "</pre>";

Answer 3

最佳方式如Medda86所示但是，您可以尝试这种方式

$array = ("00:","01:",....);
//Then you can loop over array and add the time 
for($i=0 ; $i < sizeof($array);$i++){
       $array[$i] = intval($array[$i]+6)%24;
       if($array[$i] < 10)
         $array[$i] = str_pad($array[$i],2,'0',STR_PAD_LEFT).':';
       else
         $array[$i] .= ':';
}

Answer 4

试试这个：

$yourArr = array('00:15','01:00','00:30');
foreach ($yourArr as $key => $value) {
    $timestamp = strtotime($value) + 60*60*6; // add hours as per your need.
    $time = date('H:i', $timestamp);
    $newArr[] = $time;
}
echo "<pre>";
print_r($newArr);

结果是：

Array
(
    [0] => 06:15
    [1] => 07:00
    [2] => 06:30
)

使用PHP将多个数字更改为另一个数字
