PHP は特定の時刻のタイムスタンプと mktime() 関数を取得します

mktime() 関数は、日付の Unix タイムスタンプを返します。 Unix タイムスタンプには、Unix エポック (1970 年 1 月 1 日 00:00:00 GMT) と指定された時刻の間の秒数が含まれます。

文法:
mktime(時,分,秒,月,日,年);

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>

     * 得到开始和结束unix时间段
     */</span>

    {
        <span>if</span>(<span>$mark</span> == <span>'yesterday'</span>)
