[RESOLVED] How can I get this to sort?

[adamata]

Been bugging me for a while.

Its just a little script to display the JPG and BMP files in a dir. But I just cannot get it to sort by filename

<?php

$main = ".";
$ftype1 = 'jpg';
$ftype2 = 'bmp';
$dir = opendir($main);
$j = 1;

while($filename = readdir($dir))
{
$ext = strpos($filename, $ftype1);
$ext2 = strpos($filename, $ftype2);

if ($ext == true || $ext2 == true)
{
echo '<td width="115" height="100"><a href="'.$filename.'"><img src="'.$filename.'" height="70" border="0" /></a><br />
<font size="2" face="tahoma" color=white>'.$filename.'<br /></font></td>';

if ( $j % 4 == 0 )
   {
   echo '</tr><tr>';
   }
$j++;
}
}

closedir($dir);
exit;
?>

It does exactly what I want, except for the sort part

Any ideas? I have tried a bunch of different things but with no success.

Thanks!

in the while loop, remove the echo statement. Put your filenames into an array and then use sort(). Then you can loop the array and echo your images.

yup, that did it.

Here it is, working like a charm 🙂

<?php

$main = ".";
$ftype1 = 'jpg';
$ftype2 = 'bmp';
$dir = opendir($main);
$file_list = array();
$j = 1;

//while($filename2 = readdir($dir))
while (false !== ($filename2 = readdir($dir)))
{
$ext = strpos($filename2, $ftype1);
$ext2 = strpos($filename2, $ftype2);

if ($ext == true || $ext2 == true)
{
$file_list[] = $filename2;
}
}

closedir($dir);
asort($file_list);

foreach($file_list as $one){
echo '<td width="115" height="100"><a href="'.$one.'"><img src="'.$one.'" height="70" border="0" /></a><br />
<font size="2" face="tahoma" color=white>'.$one.'<br /></font></td>';

if ( $j % 4 == 0 )
   {
   echo '</tr><tr>';
   }
$j++;
}

exit;
?>
