删除php中时间的毫秒数

Question

$t1 = '00:08:10.38474';$parts = explode(':', $t1);print_r($parts);电流输出Array ( [0] => 00 [1] => 08 [2] => 10.38474 )存储时间而不包含在字符串中的毫秒的好方法是什么？

Answer 1

如果不使用:爆炸，而是使用....

$parts = explode('.', $t1);

给...

Array

(

    [0] => 00:08:10

    [1] => 38474

)

或者

echo explode('.', $t1)[0];

给出

00:08:10

Answer 2

这只是一个技巧。如果有效，请告诉我。

$t1 = explode(".",'00:08:10.38474')[0];

$parts = explode(':', $t1);

print_r($parts);

Answer 3

尝试这个：

$t1 = '00:08:10.38474';

$parts = preg_replace('#\.[0-9]+$#', '', explode(':', $t1));

print_r($parts);

Answer 4

您可以使用一个简单的正则表达式：

$t1 = '00:08:10.38474';

if (preg_match('/^(\d{2}):(\d{2}):(\d{2})\.(\d{5})$/', $t1, $matches)) {

  [, $hours, $minutes, $seconds, $milliseconds] = $matches;

  var_dump($hours, $minutes, $seconds, $milliseconds);  // "00", "08", "10", "38474"

}
