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"}演示： https: //3v4l.org/1MUed
