PHP - Filter Directory Jpg's Using Readdir() And Timestamp
Hi all,
I have a PHP function that reads JPG's from a folder that contains over 100,000 files. The problem I have is that the READDIR() function takes a while to list the contents due to the large number of files. I'm trying to speed up the process by using a filter and listing only the files I need. Example: list files with a timestamp for an entered date period. Code: [Select] $file >= '2012-04-02 OR $file <= '2012-03-04' This lists the JPG files but my modification to list files using a timestamp does not work nor can I find a way of seeing why it does not work. This has me stuck. Thank you in advance to anyone who can post some pointers. Code that lists JPGS only Code: [Select] <?php $path = 'imgs/'; function directory($dir,$filters) { $handle=opendir($dir); $files=array(); if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}} // 'all' filter is if you set to list ALL files and folders. if ($filters != "all") { $filters=explode(",",$filters); while (($file = readdir($handle))!==false) { for ($f=0; $f < sizeof($filters); $f++): $system=explode(".",$file); if ($system[1] == $filters[$f]){$files[] = $file;} endfor; } } closedir($handle); return $files; } $files = directory($path, "jpg"); //for multiple file types just separate the file extensions by commas foreach ($files as $value) { echo $value.'<br>'; } ?> I have added the filter Code: [Select] && filemtime($file) >= strtotime('2010-04-12') but it does not work. Code: [Select] <?php $path = 'imgs/'; function directory($dir,$filters) { $handle=opendir($dir); $files=array(); if ($filters == "all"){while(($file = readdir($handle))!==false){$files[] = $file;}} // 'all' filter is if you set to list ALL files and folders. if ($filters != "all") { $filters=explode(",",$filters); while (($file = readdir($handle) && filemtime($file) >= strtotime('2010-04-12'))!==false) { for ($f=0; $f < sizeof($filters); $f++): $system=explode(".",$file); if ($system[1] == $filters[$f]){$files[] = $file;} endfor; } } closedir($handle); return $files; } $files = directory($path, "jpg"); //for multiple file types just separate the file extensions by commas foreach ($files as $value) { echo $value.'<br>'; } ?> Similar TutorialsMy new host (Siteground) cloned and moved my html/php site (built by the previous owner) from Heart Internet server. All of the site works except for the sidebar, I get these 2 errors. Anyone shed any light on these at all?

I am trying to use the readdir function to echo back all the contents of a folder. The directory that I want to read back has 31 empty folders. I am able to get them to read back, but they are in a random order and there are two additional files at the top named "." and ".." -- any idea how to fix these? Here is my code and pictures: Quote $path = "c:/test/"; if(is_dir($path)) { if($dir_handle = opendir($path)) { while($filename = readdir($dir_handle)) { echo "filename: {$filename}<br>"; } closedir($dir_handle); } } Hey guys basically with a simple script that I made I need some help with it's doing my head in. What i'm trying to do is allow multiple filetypes to be shown by readdir, i want both .zip and .rar to be in the list, not just .zip how would i add .rar in this method as well to be visible on readdir? <?php $dirname = "/home/test/"; $dir = opendir($dirname); $extension = array_pop(explode(".", $file)); ?> <?php while(false != ($file = readdir($dir))) { if ($file != "." && $file != ".." && array_pop(explode(".", $file)) == "zip") { echo(" <b>» <a href='$dirname$file'>$file - Download</a> <br /> </b> "); } } ?> Hi folks, First time posting here and a bit of a novice at PHP, but am learning.... I am fiddling with a small bit of code to create a very basic php gallery (I'm sure everyone has at some point). I started off with a mysql intergrated one then thought I would try a new one without the mysql. Its working fine but I am just having one very strange problem. Basically, I started of with just /mygallery/index.php?w=... where ... = the location (physical folder) of photos. I use opendir to open the contents of w= and parse whether it is a directory or a file (then narrow it down to just images). If it is a dir, then I present it as a link to that folder (sub-album) if it is a photo, I present a thumb link to the image. Now I have added a mod_rewrite rule to allow my urls to be of the form 'mygallery/album/subalbum' this gets ocnverted into 'mygallery/index.php?w=album/subalbum' Now the funny bit. If I create a new folder in one of the subalbum, e.g. : mygallery/album/subalbum/<b>New Folder</b> the code works. i.e. when I point my browser at 'mygallery/album/subalbum' I get a link showing 'New Folder' But if I create a new folder of any other NAME it does not appear in the list!! So if I just rename 'New Folder' to 'New Folde' it drops of the web page!!! Now I am really not sure what the hell is going on... Hope someone can help. I will post my code if necessary. Thanks in advance! Jon Reynolds Hi all I hope I have come to the right place. My system reads files stored on a drive and lists them to users through plain HTML, I made it 11 years ago and have to refresh my memory. My problem is that filenames seem to come in different formats, to how to decode/encode them is an issue...
My users use Scandinavian letters (æøåäöüõ) and it seems like one filename is in one format and another in another format. There is no logic to what format the filenames comes it. All files are ok and downloads as they should, they just dont list well. Any idea how I can handle this issue?
I've had a bit of a search around to see if this is possible but have yet to find something. I'm looking to be able to offset the results from opendir or similar function without returning all the files/folders. In other words i'd like to display the file/folder results over multiple pages when there are a lot of files/folders to display. Is this at all possible? Hi guys, I've been working on a script for a while now, and I'm sure it doesn't look great and all, and it's probably really messed up.. But right now I've finally got it working! There's only 1 thing I'd really like to add.. Searching through & listing of remote directories! The directories I'm trying to list have directory listings enabled, and I think it *should* be possible. I just have no clue how. Here's my current code in a beautiful mix of HTML and PHP: <? $border_size = "0"; function returner($what) { $what=explode("/",$what); $tps=count($what); $what=$what[$tps-1]; return $what; } $page_url= ""; $home_url=returner(__FILE__); if(isset($_GET['q'])) { $qtext=$_GET['q']; } else { $qtext=""; } function getdirsize($directory, $format=FALSE) { $size = 0; if(substr($directory,-1) == '/') { $directory = substr($directory,0,-1); } if(!file_exists($directory) || !is_dir($directory) || !is_readable($directory)) { return -1; } if($handle = opendir($directory)) { while(($file = readdir($handle)) !== false) { $path = $directory.'/'.$file; if($file != '.' && $file != '..') { if(is_file($path)) { $size += filesize($path); } elseif(is_dir($path)) { $handlesize = getdirsize($path); if($handlesize >= 0) { $size += $handlesize; } else { return -1; } } } } closedir($handle); } if($format == TRUE) { if($size / 1048576 > 1) { return round($size / 1048576, 1).'

Thanks in advance. Edit; It might help if you know what the site currently looks like. *Click* i have made an delete files script which works for only one directory but not sub directory so i want to delete files of same extention from directory and subdirectory. My current code is Code: [Select] <? $dir = 'hmm/'; function scanr($dir){ $arr = glob($dir.'/*.jpg'); foreach($arr as $vv){ //check if $vv is a file if(is_file($vv)){ //if file, get the filename $vx=explode('/',$vv); $file=$vx[count($vx)-1]; // if no extension delete the file unlink($vv); // print the deletion message echo $vv." deleted!<br>";}else{ // if $vv is a dir then scan it again for files scanr($vv); }} } scanr($dir); ?> I'm trying to echo the directory and sub directory only. I am not looking to show the files contained - only folders. What is the proper way to turn a date that is in "m/d/Y" format, into a correct timestamp. When I try strtotime, then try to change it back to a date, it shows up incorrectly (defaulting to the 1969 date that it does when it messes up. I just need to be able to turn $date = '10/15/2011'; to and from a timestamp correctly. Any advice? Hi, I have in my DB a column with a timestamp as definition. Now I would like to have only the month and year of that column for further use in a form. How can I achieve that? Thanks! I have this date in database I must convert it to Unix Timestamp How ? 2010-11-11 09:04:44 I try this echo mktime($mydate); but its not work its return wrong Timestamp becase if I convert back it I have wrong date 2011-02-16 21:01:33 I have a update query that should be updating the timestamp when a "month" field is changed. I have the following code:
$month_update->bindParam(':timestamp', strtotime (date("Y-m-d H:i:s")), PDO::PARAM_INT);
The result that is returned is 1403198033. I need it to look like this 2014-03-26 07:09:06. I know I am missing something and I would greatly appreciate your help.
Thank you so much!
How do i correctly update a timestamp? Code: [Select] $date = date("Y-m-d H:i:s"); mysql_query("UPDATE mmembers set time=now() where email=$myusername"); $epocTime = $math.newInt($math.divide("$today.getTime()", "1000"))) Hey there, Thanks for taking the time to read my thread. I've encountered a problem that I cannot figure out a way to solve. I need to calculate the remaining days until a specified unix timestamp. I haven't yet figured out how to get the amount of days until the timestamp. If anybody could tell me how to get the remaining days until a unix timestamp I would be grateful, thanks. I have a timestamp field in my mySQL table and need to check if it's 14 day or older. What's the best way to do this? Any help will be appreciated I've been having problems displaying the correct time when extracting timestamp for a graph. Wasted a lot of time trying to adjust for timezone and then finding that it didn't help. Now trying to add 2 hours to the timestamp and not sure how. Here is the line that needs to be changed I believe.
$Date=substr(mysql_result($result,$i,"Date"),11,5); Can someone help me?
hey guys I wanting some information on the best way to store a timestamp and how I would convert that timestamp to another timezone please?
im guessing I would firstly store all timestamps to the database in GMT OR BST then convert after according to users timezone preference?
Is there a good website for this please on how this is possible...thank you
any one know of any scripts to archive news items by timestamp? google searches just show tonnes of news archives.. not what i want! obviously using php, all news items have a timestamp, how would i go about this? very open ended question but ANY help would really be appreciated. Thanks! |
