PHP list files in directory

code:

// open this directory
$myDirectory = opendir(".");
// get each entry
while($entryName = readdir($myDirectory)) {
$dirArray[] = $entryName;
}
// close directory
closedir($myDirectory);
// count elements in array
$indexCount = count($dirArray);
//Print ("$indexCount files<br>\n");
// sort 'em
sort($dirArray);
// print 'em
print("<TABLE border=1 cellpadding=5 cellspacing=0 class=whitelinks>\n");
print("<TR><TH>Filename</TH><th>Filetype</th><th>Filesize</th><th>Created</th></TR>\n");
// loop through the array of files and print them all
for($index=0; $index < $indexCount; $index++) {
$checkExt = explode(".", $dirArray[$index]);
if (substr("$dirArray[$index]", 0, 1) != "." && $checkExt[count($checkExt)-1] != "php"){ // don't list hidden and php files
print("<TR><TD><a href=\"$dirArray[$index]\">$dirArray[$index]</a></td>");
print("<td>");
print(filetype($dirArray[$index]));
print("</td>");
print("<td>");
print(filesize($dirArray[$index]));
print("</td>");
print("<td>");
print(date("F d Y H:i:s.", filectime($dirArray[$index])));
print("</td>");
print("</TR>\n");
}
}
print("</TABLE>\n");
