PHP_SQL_数据库读取的“日期”处理

<code><span><span><?php </span><span>require</span>(<span>"header.php"</span>);

    <span>$sql</span> = <span>"SELECT entries.*, catetories.cat FROM entries, catetories
        WHERE entries.cat_id = catetories.id
        ORDER BY dateposted DESC
        LIMIT 1;"</span>;
        <span>//数据库知识，$sql构建查询语句（排序后，最新日期的数组为第一个，limit 1指只取一个）</span><span>$result</span> = mysql_query(<span>$sql</span>);
    <span>//把查询语句$sql通过mysql_query()语句发送到数据库，并把结果（表）存在$result中</span><span>$row</span> = mysql_fetch_assoc(<span>$result</span>);
    <span>//把$result中的表通过mysql_fetch_assoc()方法一个个存在$row数组中</span><span>echo</span><span>"<h2><a href="viewentry.php?id=%22</span>.<span>%24row</span>%5B<span>" id>].<span>"'>"</span>.<span>$row</span>[<span>'subject'</span>].<span>"</span></a></h2>
<br>"</span>;
    <span>echo</span><span>"<i>In <a href="viewcat.php?id=%22</span>.<span>%24row</span>%5B<span>" cat_id>].<span>"'>"</span>.<span>$row</span>[<span>'cat'</span>].<span>"</span></a> - Posted on "</i></span>.<span>$row</span>[<span>'dateposted'</span>].<span>""</span>;
    <span>//date("D jS F Y g.iA",strtotime($row['dateposted']))</span><span>echo</span><span>"<p>"</p></span>;
    <span>echo</span> nl2br(<span>$row</span>[<span>'body'</span>]);
    <span>//这个函数将$row['body']的内容里面的空行转换成html的<br>，最后一行关闭段落标签</span><span>echo</span><span>""</span>;
    <span>//以上涉及html代码格式，以php读取数据的方式构建html</span><span>//viewentry.php 和 viewcat.php是另外的php网页，与本次测试无关</span><span>require</span>(<span>"footer.php"</span>);
    <span>?></span></span></span></code>

直接使用$row[‘dateposted’]，显示的是：

通过函数date()和strtotime()处理后的源代码：

<code><span>echo</span><span>"<i>In <a href="viewcat.php?id=%22</span>.<span>%24row</span>%5B<span>" cat_id>].<span>"'>"</span>.<span>$row</span>[<span>'cat'</span>].<span>"</span></a> - Posted on "</i></span>.date(<span>"D jS F Y g.iA"</span>,strtotime(<span>$row</span>[<span>'dateposted'</span>])).<span>""</span>;
</code>

效果截图：

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });
