Question

我有一个名为threads的文件夹，在该文件夹中还有其他文件夹。我无法将这些文件夹读入数组，然后将它们放入选择框中。这是我的代码。

<select value="Please Select a Genre" >
<?php
$threads = array();
if ($handle = opendir('/Threads/')) {
    while (false != ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {

            array_push($threads,"$file");
            print_r ($threads);


        }
    }
    sort($threads);
    print_r ($threads);
    for ($i = 0; $i < count($threads); $i++) {

        print "<option value=\"$threads[$i]\">$threads[$i]</option>";
    }


    closedir($handle);
    ?>

</select>
<br />
<input type=\"submit\" name=\"submit\" value=\"Submit\" />
</form>
</center>
</body>
</html>

您在源代码中有错误。

你错过了关闭}

    <select value="Please Select a Genre" >
<?php
$threads = array();
if ($handle = opendir('/Threads/')) {
    while (false != ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {

            array_push($threads,"$file");
            print_r ($threads);


        }
    }
}
    sort($threads);
    print_r ($threads);
    for ($i = 0; $i < count($threads); $i++) {

        print "<option value=\"$threads[$i]\">$threads[$i]</option>";
    }


    closedir($handle);
    ?>
    </select>
<br />
<input type=\"submit\" name=\"submit\" value=\"Submit\" />
</form>
</center>
</body>
</html>
