php script that displays last uploaded jpg in a directory

[robinpg.SHU@gmail.com]

As title really, does anyone know of (or could write?) a php file which
in a directory of .jpg files display the most recent added to that
/dir?

Can anyone help?

<?php
$ctime = 0;
foreach (glob('*.jpg') as $file)
{
if ($ctime > filectime($file ))
{
$match = $file;
$ctime = filectime($file );
}
}

print $file;
?>

I noticed that Message-ID:
<1107711381.614 337.85260@f14g2 000cwb.googlegr oups.com> from
robinpg.SHU@gma il.com contained the following:

I think i'll have to elaborate on my original question a little
further, when I say display I mean literally display the image in an
img src HTML tag.

Cheers

Well then, instead of:

print $file;

... then ...

print '<img src="' . htmlentities($f ile) . '" alt="whatever"> ';

Hmm, I still cant get it to work. It doesnt appear to like the $ in
line16.

With the code from Andy you get the file name. What else do you need?

Re: php script that displays last uploaded jpg in a directory

Well, ive got a random php script (below) which I can literally have it
as an image:

<img src=http://whatever.com/random.php>

and I want a similar thing to instead display the last updated image
from the dir.

[code:

<?php
$fileList = array();
$folder = ".";
$handle = opendir($folder );
while (
false !== ( $file = readdir($handle ) )
) {
if (
substr($file, -4) == ".gif" ||
substr($file, -4) == ".jpg"
) {
$fileList[count($fileList )] = $file;
}
}
closedir($handl e);
$randNum = rand( 0, (sizeOf($fileLi st) -1) );
if (
substr($fileLis t[$randNum], -4) == ".gif"
) {
header ("Content-type: image/gif");
} elseif (
substr($fileLis t[$randNum], -4) == ".jpg"
) {
header ("Content-type: image/jpeg");
}
readfile($fileL ist[$randNum]);
?>

[end code]

Re: php script that displays last uploaded jpg in a directory

I have managed to find a solution, and for anyoen who may want
something similar, thanks to all above:

<?php

$path = './';
// with trailing slash, for images in other dirs: $path =
'./foldername/'



unset($fpath, $time, $time, $ext, $type);

$type = array
(
// ---------------------------
// ext mime type

'png' => 'image/png',
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
'jpe' => 'image/jpeg',
'gif' => 'image/gif',
'tiff' => 'image/tiff',
'tif' => 'image/tiff',
);

if ( is_dir($path) )
{
if ( $dh = @opendir($path) )
{
while ( ($file = readdir($dh) ) !== false )
{
if ( $file == '.' or $file == '..' )
{
next;
}
// echo $file . " :";

// Var with full path+name
$fpath = $path.$file;

// Skip if dir
if ( is_dir($fpath) )
{
next;
}

// echo $fpath . " ::";

// Get file extension
$ext = substr ( $fpath, strrpos($fpath, '.') + 1 );

// Should get most recent file
if ( isset($type[$ext]) )
{
$mtime = filemtime($fpat h);

if ( $mtime > $time )
{
$img = array ( 'fpath' => $fpath, 'name' => $file, 'ext' => $ext
);

$time = $mtime;
}
}
}
}

closedir($dh);

if ( $img['name'] != '' )
{
if ( $fh = @fopen($img['fpath'], "rb") )
{
@header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT'); //
Date in the past
@header( 'Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); //

@header( 'Cache-Control: no-cache, must-revalidate'); //

@header( 'Pragma: no-cache'); //

@header( 'Content-Disposition: inline; filename="'.$im g['name'].'"'
);
@header( 'Content-transfer-encoding: binary');
@header( 'Content-Length: '.(string)(file size($img['fpath'])) );
@header( 'Content-Type: '.$type[ $img['ext'] ] );

// @header( 'Content-Type: '.$type[ $img['ext'] ] );
// @header( 'Content-Disposition: inline;
filename="'.$im g['name'].'"' );
// @header( 'Content-Length: '.(string)(file size($img['fpath'])) );

while ( ! feof($fh) )
{
echo fread($fh, 8192);
}
@fclose($fh);

exit;
}
}
}




$filedata =
base64_decode(' R0lGODlhAQABAIA AAMDAwAAAACH5BA EAAAAALAAAAAABA AEAAAICRAEAOw== ');
$filesize = strlen($filedat a);

@header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date
in the past
@header( 'Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); //

@header( 'Cache-Control: no-cache, must-revalidate'); //

@header( 'Pragma: no-cache'); //

@header( 'Content-disposition: inline; filename=blank. gif');
@header( 'Content-transfer-encoding: binary');
@header( "Content-Length: $filesize");
@header( 'Content-type: image/gif');

echo $filedata;
exit;
