Question

I have a a FOR loop that lists all files within a certain directory. One of the results is also INDEX.PHP, a result which I don’t need. It’s the first result/entry of the loop…

Is there any way to skip this first result and start looping from the second one?
Please help.

    <?php
$myDirectory = opendir('.');

while($entryName = readdir($myDirectory)) 
{
    $dirArray[] = $entryName;
}

closedir($myDirectory);

$indexCount = count($dirArray);
echo '<h5>There are ' . $indexCount . ' files in the Media Center</h5>';

sort($dirArray);

echo '<table width="100%">';
echo '<tr>';
echo '<th width="33%" align="center" class="admin_th" style="border-radius: 10px 0 0 0">Download</th>';
echo '<th width="33%" align="center" class="admin_th">Filetype</th>';
echo '<th width="33%" align="center" class="admin_th" style="border-radius: 0 10px 0 0">Filesize (in bytes)</th>';
echo '</tr>';

for($index = 0; $index < $indexCount; $index++) 
{
    if (substr("$dirArray[$index]", 0, 1) != ".")
    {
        echo '<tr><td width="33%" align="center" class="admin_td-even"><a href="' . $dirArray[$index] . '">' . $dirArray[$index] . '</a></td>';
        echo '<td width="33%" align="center" class="admin_td-odd">';
        echo strtoupper(substr($dirArray[$index], -3));
        echo '</td>';
        echo '<td width="33%" align="center" class="admin_td-even">';
        echo filesize($dirArray[$index]);
        echo '</td>';
        echo '</tr>';
    }
}
echo '</table>';
?>

I see two ways of doing it:

• You can start one index later:

Instead of for($index = 0; $index < $indexCount; $index++) { ...},
do

for($index = 1; $index < $indexCount; $index++) { ...}

• You can also add a condition:

for example:

for ($index = 0; $index < $indexCount; $index++) {
  if ($dirArray[$index] == 'INDEX.PHP') continue;
  // rest of the loop
}

But they are a few ways you can improve your code. Instead of using opendir() and readdir(), you can just use scandir like this:

foreach (scandir('.') as $file) {

}

But it looks like you want to grab some media file and display them. So an even better solution would be to use the glob() function, like this:

foreach (glob("*{.mp3,.mp4,.jpg,.png}", GLOB_BRACE) as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
