PHP erhält einen bestimmten Zeitstempel und die Funktion mktime()

Die Funktion mktime() gibt den Unix-Zeitstempel eines Datums zurück. Ein Unix-Zeitstempel enthält die Anzahl der Sekunden zwischen der Unix-Epoche (1. Januar 1970, 00:00:00 GMT) und der angegebenen Zeit.

Syntax:
mktime(Stunde, Minute, Sekunde, Monat, Tag, Jahr);

Beispiel:

<code><span><span><?php</span><span>$d</span>  = mktime(<span>9</span>, <span>12</span>, <span>31</span>, <span>6</span>, <span>10</span>, <span>2015</span>);
    <span>echo</span><span>"创建日期是 "</span> . date(<span>"Y-m-d H:i:s"</span>, <span>$d</span>);
<span>?></span></span></code>

Das Obige stellt PHP vor, um einen Zeitstempel einer bestimmten Zeit und die Funktion mktime() zu erhalten, einschließlich des relevanten Inhalts. Ich hoffe, dass es für Freunde hilfreich sein wird, die an PHP-Tutorials interessiert sind.
