we have a directory with pics, that a user can associate with his data in a
form. we use opendir/readdir to show the directory contents. unfortunately,
this is not sorted. How can we achieve a listing in alphabetical order?
this is our code:
echo "<select name='image'>";
echo "<option value=''>please select</option>";
$fp = opendir("../pics/");
while ($file = readdir($fp)) {
$selectfile="/pics/".$file;
if ($file=="." OR $file=="..") { } else {
$string_image .= "<option value='/pics/".$file."'";
if ($selectfile==$image) { $string_image .= " SELECTED"; }
$string_image .= ">".$file."</option>";
}
}
echo $string_image;
echo "</select>";
