php sort values of a array - php

Question

id love a little help with the sort function here, im trying to figure it out but cant.
<?php
if ($handle = opendir('uploads')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".."){
sort ($file);
$thelist .= '<li>'.$file.'<img src="uploads/'.$file.$media.'" width="25" height="25"</li>';
}
}
closedir($handle);
}
?>
<ul><?php echo $thelist; ?></ul>
so this doesnt sort...
and the following will, but wont display some files.
im only interested in the sort function for the top code, i paid a guy to write the following half to try to understand the function sort
from what i can figure were suggesting the $file displays for a list then for a photo using the various $.. im stuck with whats stopping the $file from getting alphabeticaly arranged before being told what to display, (the best i got to was a list of the number ones displaying alphabetical (numerical yes) but its not sorting)
function showDir($dir, $i, $lar, $lon, $lin)
{
print("<style>.box { border-style: outset ; border-width: 1px ; border-color: #A3C5CC ; border-radius: 8px ; -moz-border-radius: 8px }</style>") ;
print("<script language='JavaScript'>
<!--
function MM_openBrWindow(theURL,winName,features) { //v2.0
window.open(theURL,winName,features);
}
//-->
</script>") ;
$i++;
if($checkDir = opendir($dir))
{
$cFile = 0;
while($file = readdir($checkDir))
{
if($file != "." && $file != "..")
{
if(!is_dir($dir . "/" . $file))
{
$listFile[$cFile] = $file;
$cFile++;
}
}
}
if(count(#$listFile) > 0)
{
print("<table cellspacing='1' cellpadding='0' border='0'><tr>") ;
sort($listFile);
$x = 0 ;
for($k = 0; $k < count($listFile); $k++)
{
$spacer = "";
for($l = 0; $l < $i; $l++)
$spacer .= " ";
if($x % $lin == 0)
print("</tr><tr>") ;
$img = $listFile[$k] ;
$tmp = explode(".", $img) ;
$x++ ;
if($tmp[1] == 'jpg' OR $tmp[1] == 'bmp' OR $tmp[1] == 'gif' OR $tmp[1] == 'png'
OR $tmp[1] == 'tga' OR $tmp[1] == 'tif' OR $tmp[1] == 'eps')
{
print("<td>") ;
print("<table class='box' bgcolor='#9ABBC1' cellspacing='0' cellpadding='0' border='0' width='" . ($lon+10) . "' height='" . ($lar+27) . "'><tr>") ;
print("<td align='center'><small><b>" . ($k+1) . "</b></small></td></tr><tr>") ;
print("<td align='center'>") ;
$srcimg = $dir . "/" . $spacer . $img ;
list($width, $height, $type, $attr) = getimagesize($srcimg);
print("<a href='#' onClick=\"MM_openBrWindow('display.php?img=$srcimg&lon=$width&lar=$height','','width=" . $width . ",height=" . $height . ",left=100,top=100,scrollbars=no,toolbars=no')\">") ;
print("<img src='" . $srcimg . "' width='" . $lar . "' height='" . $lon . "' alt='" . $img . "' title='" . $img . "' border='0'></a></td>");
print("</tr></table>\n") ;
print("</td>") ;
}
else
$x-- ;
}
print("</tr></table>\n") ;
print("<br><small>" . $k . " Images displayed<b></b></small>") ;
}
closedir($checkDir);
}
}
}
?>

Answer 1

You should use scandir function instead of readdir.
sorting_order By default, the sorted order is alphabetical in
ascending order. If the optional sorting_order is set to
SCANDIR_SORT_DESCENDING, then the sort order is alphabetical in
descending order. If it is set to SCANDIR_SORT_NONE then the result is
unsorted.

<?php
if ($handle = opendir('uploads')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != ".."){
$files[] = $file;
}
}
sort ($files);
$thelist = '';
foreach ($files as $file) {
$thelist .= '<li>'.$file.'<img src="uploads/'.$file.'" width="25" height="25"</li>';
}
closedir($handle);
}
?>
<ul><?php echo $thelist; ?></ul>
