PHP - Readdir Question
Sorry for the noobie question, I am just a beginner still. 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); } } Similar TutorialsHey 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?
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>'; } ?> 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? My 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?
Warning: readdir(): supplied argument is not a valid Directory resource in /home/customer/www/dunster.org.uk/public_html/include/toolbox.php on line 97

If not 2 goes to the next input statement. Here is code I was experimenting with: <html> <body> <form action="" name="test" method='POST'> <input type="radio" id="sex" value=1 checked><label>Male</label> <input type="radio" id="sex" value=2><label>Femaleale</label> <?php $result = "value"; if ($result == 2) echo "<input type='int' id='gradYear' size='3' required>"; else echo "Not a female!" ?> <input type="submit" value="GO"> </form> </body> </html> The code passes debug, however, Not a Female is displayed. My question is - Can I do this and if so, what value do I test against id='sex' or value. I tried each one but gave the same results. I realize that $_POST[sex] would be used after the submit button is clicked. But this has me stumped. Thanks for the assis in advance. Major breakthrough. utf8_encode() allows me to view utf-8 characters in the browser. Therefore, my source data file must be ISO-8859-1 encoded text, right? Am I understanding this correctly?
<?php
//mb_internal_encoding("UTF-8");
header('Content-type: text/html; charset=utf-8');
$file = fopen('some_csv_file_created_by_excel.csv', "r");
ob_start();
while (($spec = fgetcsv($file, 100000, ",")) !== FALSE){
echo($spec[0].' '.utf8_encode($spec[0]).'<br>');
}
$string=ob_get_clean();
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body>
<p><?php echo($string);?></p>
</body>

Edited by NotionCommotion, 11 January 2015 - 08:22 PM. i am trying to understand, how a site like ebay can display content and be case insensitive? for example: The original url: http://www.ebay.co.uk/itm/Toshiba-Satellite-C50-AMD-E-Series-1-4GHz-Dual-Core-15-6-Inch-500GB-2GB-Laptop/151458954958the above works fine and go to the intended page. user editing the browser url into lowercase : http://www.ebay.co.uk/itm/toshiba-satellite-c50-amd-e-series-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958random uppercase and lowercase. http://www.ebay.co.uk/itm/toshiba-sateLLite-c50-aMd-e-sERIes-1-4ghz-dual-core-15-6-inch-500gb-2GB-laptop/151458954958both the urls above also work fine and go to the intended page. How can such a thing can work? it is supposed to throw an error such as page not found and the like? any thoughts welcome. Code: [Select] <?php if ($News_1_Status=="Y") echo <div class="newstitle" align="left"><?php echo $News_1_Date;?> <a href="<?php echo $News_1_URL;?>"><?php echo $News_1_Name;?></a></div><br>; else echo "Have a nice day!"; ?> how do i get the above script working any clue? I am trying something simple, creating some horses and making them race using OOP, creating them is easy, how can i find out which one "won" based on the highest total. Here is what i got so far Code: [Select] <?php class Horse { public $strength; public $speed; public $agility; public function create($name,$age,$odds){ $this->name=$name; $this->odds=$odds; $this->strength=(rand(50,200) * $this->odds - $this->age); $this->speed=(rand(100,400) * $this->odds - $this->age); $this->agility=(rand(150,250) * $this->odds - $this->age); $all=array(0=>"$this->strength",1=>"$this->speed",2=>"$this->agility"); echo "<b>$this->name</b> has a strength of <b>$this->strength</b>, a speed of <b>$this->speed</b> and agility at <b>$this->agility</b>. --- <b>".array_sum($all)."</b><br>"; } } $mix=rand(2,6); $a=new Horse; $a->create("Dave", 2, $mix); $a->create("Dude", 3, $mix); $a->create("Evan", 3, $mix); $a->create("Jill", 15, $mix); $a->create("Flex", 10, $mix); ?> I cant figure out a way to find out who had the highest total, i would love to know what i am doing wrong. Hello, i am currently working on a project and i have been on google and nothing has helped i am trying to detect characters in the URL so for example XSS if someone typed in the URL:
home.php?=<script>document.cookie();</script>
OR
home.php?=<?php echo file_get_contents("document.txt", "a");
How would i be able to make a kind of firewall to detect this?
and if it does then redirect to another page.
Thanks.
i am looking for a way to write a php script to pull information from a html table and put that information in to the databases does any one have any idea who to do this I have been away from PHP for a long time and I was looking over my old scripts. I did PHP OOP at one time and I used a paticular method to connect all my methods up and load them. I have been looking at other peoples code and when I look at my code it does not even feel like OOP, I want to know how to you link all the methods (or is it called functions?) in a class up and return them? I use to do this: Code: [Select] <?php class quickFUNC { function note_pad() { // code for notepad } function quickAdminFunc() { // code for admin func $this->note_pad(); } } $quickFUNC = new quickFUNC; if(isset($_GET['id'])) { $act = $_GET['id']; } else { $act = NULL; } switch ($act) { case 1: //some random code to launch case 1 break; default: $quickFUNC ->quickAdminFunc(); ?> This was my code back in the days, as you can see the notepad was called in the admin function then made the admin function default in the case switch. I looked at all my script and the all are layed out like this :S.. Can I get some help please, thank you. hi php people, I am wondering will if the code below will work when I call $C->getafoo() will I get foo; I keep getting an error at this point return $this->A->a(); saying the method is not there Code: [Select] class A{ public function a(){ return "foo"; } } class B { public $A; function __construct($A) { $this->A = $A; } public function geta(){ return $this->A->a(); } } class C extends B{ public function getafoo(){ return geta(); } } $C = new C(new A()); echo $C->getafoo(); Looking at a forum like PHPbb or similar. Wondering if anyone can tell me how the system (or scripts) manages to pull all the user information when viewing a thread without a massive amount of database calls? For example, lets say 1 thread has 10 different users associated to it. When you view the thread, on the left you see the username, their avatar, when the membership was created, maybe even the users level or amount of interaction. So, for each thread view (or page view) does the program do a SQL Select back to the user database for each user's information or is the users information being pulled from cache somewhere? Any insight into the logistics is greatly appreciated! hello all, i am having a for each problem. im trying to get two post fields using the foreach function. here is what i have in my form.php: Code: [Select] <?php foreach($_POST['staff'] as $value) { echo "$value - <br />"; } ?> the name of the the fields coming in are Code: [Select] name='staff[]' and the second one is name='descr[]' fields += 1; Code: [Select] /*** a new dom object ***/ $dom = new domDocument; /*** load the html into the object ***/ @$dom->loadHTML($file); /*** discard white space ***/ $dom->preserveWhiteSpace = false; /*** the table by its tag name ***/ $tables = $dom->getElementsByTagName('table'); /*** get all rows from the table ***/ $rows = $tables->item(0)->getElementsByTagName('tr'); /*** loop over the table rows ***/ foreach ($rows as $row) { /*** get each column by tag name ***/ $cols = $row->getElementsByTagName('a'); /*** echo the values ***/ echo $cols->item(0)->nodeValue.'<br />'; } Hi, Is there a way to start to echo from 43? thanks. I'm considering getting a VPS, but I'm not entirely sure what this would be able the handle. The specs doesn't look that good to me, but my friend swears it will handle running apache/php/mysql handling large websites and databases without a problem. I want to run multiple databases that just store statistics and I'm a bit worried about the RAM and the company doesn't even mention a cpu. Here's the specs: 256MB RAM 300GB HDD 10Mbps unmetered 1 IP Address My friend runs two counter-strike: source servers off his VPS (same stats).. so I'm actually considering this, but it just seems like it's not powerful enough. Oh.. forgot the most important part.. it's only $9. Hey, I have a while that shows the rows(duh). What i want to do is: show 3 rows then echo float left or clear both. So basically 3 at a time, but it shows all the rows in a nice order. Can someone do this? Cheers. |
