mktime() 函數傳回日期的 Unix 時間戳記。 Unix 時間戳包含 Unix 紀元（1970 年 1 月 1 日 00:00:00 GMT）與指定時間之間的秒數。

語法：
mktime(hour,minute,second,month,day,year);

實例 :

<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>
