我需要链接到我的下拉菜单中的外部网站,该菜单中包含每周五更改文件名的pdf。我以前曾问过这个问题,但我是php的初学者,所以我很难实现它。任何帮助将不胜感激。

www.extranet.frostyacres.com/portal_resources/1/Market Report 06-14-13.pdf

我试图在html文件的下拉菜单中使用它,不确定是否可能。

$startingDate = strtotime('2013-06-07');
echo '<a href="https://www.extranet.frostyacres.com/portal_resources/1/Market Report ' . date('m-d-y', $startingDate) . '.pdf">Market Reports</a>';

您可以使用:

echo Date('m-d-y', strtotime("Last Friday"));

要显示上周五,然后添加您想要显示的周五数量的次数(-7),如下所示:

function display_last_fridays($n) {
    for ($i=0;$i<$n;$i++) {
        echo Date('m-d-y', strtotime($i*-7 . " days Last Friday")) . "<br/>";
    }
}
display_last_fridays(5);

<?php

    // all fridays from startingdate till NOW
    $display_only_the_most_recent_friday = false; // all fridays or most recent only
    $startingDate = strtotime('2013-01-01'); // lets test from start of 2013

    $start = time(); // now
    $end = $startingDate; // our loop will $start from now and scan back till the $end

    // we will check every day from $start to $end
    // in every loop we are going one day back -=(60 * 60 * 24)
    for($checkdate=$start;$checkdate>=$end; $checkdate -=(60 * 60 * 24))
    {
        if ( date('N', $checkdate) == "5" ) // and if this day is the fifth day we echo
        {
            echo '<a href="https://www.extranet.frostyacres.com/portal_resources/1/Market Report '.date('m-d-y', $checkdate).'.pdf">Market Reports</a>';
            if($display_only_the_most_recent_friday)
                break;
        }
    }

?>
