Use $row['dateposted'] directly, what is displayed is:
Source code processed by functions date() and strtotime():
<code><span>echo</span><span>"<i>In <a href="viewcat.php?id=%22</span>.<span>%24row</span>%5B<span>" cat_id>].<span>"'>"</span>.<span>$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>

The above introduces the "date" processing of PHP_SQL_database reading, including the relevant aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
