Question

我想从第一句话和第二句话[括号内]获取时间，如下所示，结果一分钟即可看到差异。例如，在这种情况下，结果将是1分钟。

[04:38:41] Preflight started, flying offline
[04:39:29] Pushing back with 7512 kg of fuel

如果您能帮助我找出如何用PHP做到这一点，我表示感谢。

谢谢

Answer 1

您可以使用以下示例获取两者之间的秒数：

$datetime1 = strtotime('11:01:00');
$datetime2 = strtotime('11:00:01');

echo abs($datetime1-$datetime2);

Answer 2

您可以使用以下示例以秒为单位获取差异。

$string1 = '[04:38:41] Preflight started, flying offline';
$string2 = '[04:39:29] Pushing back with 7512 kg of fuel';

$datetime1 = substr($string1,4,6); // Getting the time of the first string
$datetime2 = substr($string2,4,6); // Getting the time of the second string

echo abs($datetime1-$datetime2); // Calculating the difference between the two values.

Answer 3

尝试

<?php
$time1 = explode(':', "04:38:41");
$time2 = explode(':', "04:39:29");
echo $result =  $time2[1] - $time1[1];
?>

或者，您可以阅读全文

<?php
$time1_string = "[04:38:41] Preflight started, flying offline";
$time2_string = "[04:39:29] Pushing back with 7512 kg of fuel";
$time1 = explode(':', $time1_string);
$time2 = explode(':', $time2_string);
echo $result =  $time2[1] - $time1[1];
?>

Answer 4

您也可以使用preg_match()

来获得所需的结果

示例：

from PIL import Image

im = Image.open("Picture2.png")
rgb_im = im.convert('RGB')
rgb_im.save('Picture2.jpg')
