Sort image files in recent order - php

Question

Asked this but still not getting the right code that fits in with this one. The reason why i don't want to change the code is because the pagination system works.
I've tried the arsort, rsort and many other sorting functions but the images still don't show the recent images that were in my directory.
<?php
$page = "";
$record_count = 100;
$dir = ('uploaded/');
$offset = ($page-1)*$record_count;
$files = glob("uploaded/*.*");
$files_filter = array(arsort($files,$record_count));//made sorting changes here
$images = array(arsort(glob($dir . '*.*', GLOB_BRACE)));
$latestimage = $images[0];
$large = '';
$allow = array('jpg','jpeg','gif','png', 'JPEG', 'JPG','GIF','PNG');
$i=0;
$open = opendir($dir);
// get each filename from directory
while (($file=readdir($open))!==false) {
// get extension
$ext=str_replace('.', '', strrchr($file, '.'));
// does it have a valid extension
if (in_array($ext, $allow))
$list[$i++]=$file; // store valid filename in array. use numerical indexing as makes it easier to display paginated images later
}
$perPage=20; // number of images to show per page
$total=count($list); // total number of images to show
$pages=ceil($total/$perPage); // number of pages is the number of images divided by how many per page
$thisPage=isset($_GET['pg'])?$_GET['pg']-1:0; // did user select a specific page? Note, pages on web are counted from 1 (not zero) so must subtract 1 for correct indexing
$start=$thisPage*$perPage; // calculate starting index into list of filenames
$perRow=2; // how many images to be shown on each row
// display quick index to pages. all pages except current page output as a link
print "Page ";
for ($i=0;$i<$pages;$i++)
if ($i==$thisPage)
print " ".($i+1);
else
print " <a href='?pg=".($i+1)."'>".($i+1)."</a>";
print "<tr>";
$imgCnt=0; // used to count number of images displayed and hence whether to wrap page. note, could use "for" index $i but this is computationally quicker
for ($i=$start;$i<$start+$perPage;$i++) {
// may be too few images to fill page, so check if we have a valid array index. if we don't output empty table cell so fussy browsers
// don't mis-display table due to missing cells
if (isset($list[$i]))
print "<td><a target='_new' href='$dir$large{$list[$i]}'><img style='height:180px;width:180px; border:2px solid black; margin:20px 0px 10px 10px; *margin:10px 0px 10px 20px;' style='border-color:#000000 ' border='1' src='$dir{$list[$i]}'></a></td>";
else
print "<td></td>";
$imgCnt+=1; // increment images shown
if ($imgCnt%$perRow==0) // if image count divided by number to show per row has no remainder than it's time to wrap
print "</tr><tr>";
}
print "</tr>";
closedir($open);
?>

You should index your list on modify time and slice your array when you want to show them.
Update: you should use krsort
// the paths
$dir = '/var/www/uploads/';
$urlPath = 'http://localhost/uploads/';
$allow = array('jpg','jpeg','gif','png', 'JPEG', 'JPG','GIF','PNG');
$open = opendir($dir);
while( $file = readdir( $open ) ){
$ext = strtoupper( pathinfo( $file, PATHINFO_EXTENSION ) );
if( in_array( $ext, $allow ) ){
$modifyTime = filemtime( $dir . $file );
$list[ $modifyTime ] = $file;
}
}
# reverse sort on key
krsort( $list );
$perPage = 20;
$total = count($list);
$pages = ceil($total/$perPage);
$thisPage = isset($_GET['pg'])?$_GET['pg']-1:0;
$start = $thisPage*$perPage;
echo "Page ";
// show pages
for ($i=0;$i<$pages;$i++):
if ($i==$thisPage) :
print " ".($i+1);
else :
print " <a href='?pg=".($i+1)."'>".($i+1)."</a>";
endif;
endfor;
// show images
$items = array_slice( $list, $start, $perPage );
foreach( $items as $image ){
echo "<br/> " . $image . "<br/>";
echo "<a target='blank' href='" . $urlPath . $image . "'><img width='100' height='100' src='" . $urlPath . $image . "'/></a>";
echo "<br/>";
}
closedir($open);
