PHP - Php File (size) Download Limit?
Hi Chaps,
I'm using readfile to force the download of a file: set_time_limit(0); $file = 'monkey.gif'; if (file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename($file)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); exit; } flush(); And this works fine, however, I do have some software installation files that could be downloaded (these are in excess of 280Mb). I have checked php.ini: Quote memory_limit = 128M post_max_size = 300M But Internet Explorer hangs and then crashes. Is there a way to allow big files to download using this method, or is there another way of forcing the download, without php 'reading' the file first? I'm guessing that the problem lies with the memory_limit being smaller than the file size. Is it a good idea to increase the memory_limit to eg. 280Mb? Cheers Similar TutorialsI have a simple script which records search terms and writes them to an external file. I would like to limit this file size. The Use: I have a search page where people can search for PDF files. I would like to have a 'cloud tag' or list of the most recent terms searched at the bottom of the page. Here is my script which works beautifully: <?php $pattern = "/filetype:(\w+)/"; // filteype:(wildcard for word) to grab the file extension along with the word filetype: if ( $_GET['q'] == "" ) { $term = ""; } else { $term = preg_replace("$pattern", '', $_GET['q']); // get rid of the filetype parameter } $searched = $term . ", "; $fopen = fopen("searched.html", "a"); fwrite($fopen, $searched); fclose($fopen); ?> The above code grabs the search term when the SERP page is opened, and writes it to a file. I will later use phpInclude to put the contents of that file on the bottom of my search engine page. The problem is that after a million searches, this file will be huge! Question: How can I limit the file size and organize these search terms so that the most recent ones appear on the page? Hi guys, with code below i can upload pictures to database, however i need to limit the file upload. I have this code done with help of php freak forum and i am a newbie so can u help me please? thanks in advance if (isset($_POST['register']) && $_POST['register']){ //image1 $nameone=$_FILES['myfileone']['name']; if ($nameone) { $dst_filename = resize_upload_image($_FILES['myfileone'], "images/"); if ($dst_filename !== false) { extract($dst_filename); $image1 = mysql_query ("INSERT INTO img SET image='$img_filename', thumb='$thumb_filename', refimage='$reference'"); } } } ?> <form action='' method='POST' enctype='multipart/form-data'> <p>File: <input type='file' name='myfileone'> I'm trying to add a file size limit to my upload form-code (below) Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved.... I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP? I am currently using PHP 5.3.2 on IIS 7 and I am wondering how can I write a download script with resume and speed limit. After looking for a while, I found this script that works on speed limit: Code: [Select] <?php $local_file = 'file.zip'; $download_file = 'name.zip'; // set the download rate limit (=> 20,5 kb/s) $download_rate = 20.5; if(file_exists($local_file) && is_file($local_file)) { header('Cache-control: private'); header('Content-Type: application/octet-stream'); header('Content-Length: '.filesize($local_file)); header('Content-Disposition: filename='.$download_file); flush(); $file = fopen($local_file, "r"); while(!feof($file)) { // send the current file part to the browser print fread($file, round($download_rate * 1024)); // flush the content to the browser flush(); // sleep one second sleep(1); } fclose($file);} else { die('Error: The file '.$local_file.' does not exist!'); } ?> Though there is a big problem that the download file comes without extension. For example if the original file is file.ext then the client will receive it as file without any extension. I just want to use octet-stream since I have no interest in streaming or other things, but I really want the client to have the extension also. So could you please tell me what is wrong with the above script, and please show me a way to do resume download. Thank you very much for your help. I have a form which has a variable size, depending on the number of rows in a table. For each row there are about ten fields, and I simply show them all for each row. I've recently started having a trouble in that if I create a form with more than 400 elements, then the $_POST variable is truncated at 400. Is this normal? Do I have to limit the size of the $_POST array? Not by MB, which must be trivial for me, but for the number of array elements? Hi, I wanted to realize an upload form for a max. file size of 5GB. Don't ask me why, but my friend needs that. Now I set up a webserver with ISPConfig and this interface provides a lot of features including openbasedir. Uploading files up to 80MB is no problem but choosing bigger files causes the following errors: [Mon Sep 12 23:39:03 2011] [warn] [client XX.XX.XXX.XXX] mod_fcgid: stderr: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 97477678 bytes) in Unknown on line 0, referer: hxxp://www.mydomain.com/kontakt-upload.html [Mon Sep 12 23:39:03 2011] [error] [client XX.XX.XXX.XXX] Premature end of script headers: file-uploader.php, referer: hxxp://www.mydomain.com/kontakt-upload.html [Mon Sep 12 23:39:03 2011] [warn] [client XX.XX.XXX.XXX] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: hxxp://www.mydomain.com/kontakt-upload.html [Mon Sep 12 23:39:03 2011] [error] [client XX.XX.XXX.XXX] Premature end of script headers: index.php, referer: hxxp://www.mydomain.com/kontakt-upload.html As I see the upload get's buffered in the PHP Memory area instead directly to the harddrive. How could I fix that? Hello I already know this is possible with php <?php $file = 'monkey.gif'; if (file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename($file)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); exit; } ?> But I am wondering is it possible to just send over a string of data stored in like $data and create a file clientside (nothing server side). So i'm guessing readfile() has to be replaced with something Dear PHPFreak members, I have been searching a solution for serving a file download via my website. The file to be downloaded is actually on a remote server. What i need is a code that serves as a download medium without actually downloading the file to my web server. Something like masking file url Can anyone help me with it ??? Have been trying this since days. But no solution till date. I have this code which uploads fine but I am trying to limit the type of files users can upload. For some reason this code still let any file type to be uploaded being very new to php any help would be Appreciated. Quote Code: [Select] <?php if ((($_FILES["image"]["type"] == "image/gif") || ($_FILES["image"]["type"] == "image/jpeg") || ($_FILES["image"]["type"] == "image/pjpeg")) && ($_FILES["image"]["size"] < 20000)) { if ($_FILES["image"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["image"]["name"] . "<br />"; echo "Type: " . $_FILES["image"]["type"] . "<br />"; echo "Size: " . ($_FILES["image"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["image"]["tmp_name"]; } } $target = "testimages/"; $target = $target . basename( $_FILES['image']['name']); // $company=$_POST['company']; $image=($_FILES['image']['name']); mysql_connect("localhost", "user", "pass") or die(mysql_error()) ; mysql_select_db("testupload") or die(mysql_error()) ; mysql_query("INSERT INTO `table` (company, image) VALUES ('$company', '$image')") ; if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; } else { echo "Sorry, there was a problem uploading your file."; } ?> Hello! I have this validation script that seems to work great until I add the size validation. I'm ready to pull my hair out! Can someone tell me what I'm doing wrong? Code: [Select] if (isset($_POST['Submit'])) { $user_id = $userdata[user_id]; $number_of_file_fields = 0; $number_of_uploaded_files = 0; $number_of_moved_files = 0; $uploaded_files = array(); $max_filesize = 5242880; // Maximum filesize in BYTES (currently 5MB). $upload_directory = dirname(__file__) . '/'.$user_id.'/'; //set upload directory if (!is_dir($upload_directory)) { mkdir($upload_directory, 0777, true); } for ($i = 0; $i < count($_FILES['images']['name']); $i++) { $number_of_file_fields++; if ($_FILES['images']['name'][$i] != '') { //check if file field empty or not $number_of_uploaded_files++; if($_FILES['images']['size'] > $max_filesize){ echo "<b class='red'>Max file size is 5MB.</b><br/>"; $sz = true; } $ext = validate_extension($_FILES['images']['name'][$i]); if (($ext == true) && ($sz == true)){ $uploaded_files[] = $_FILES['images']['name'][$i]; if (move_uploaded_file($_FILES['images']['tmp_name'][$i], $upload_directory . $_FILES['images']['name'][$i])) { $number_of_moved_files++; } }else { echo "<b class='red'>File extention error. Only .doc, .pdf, .jpg and .gif files are allowed. </b><br/>"; } } } if ($number_of_uploaded_files >= 1){ echo "Number of files submitted:<b class='red>".$number_of_uploaded_files."</b><br/>"; echo "Number of successfully uploaded files:<b class='red>".$number_of_moved_files."</b><br/><br/>"; echo "Uploaded File Name(s):<br/>" . implode('<br/>', $uploaded_files); } } As of now it results in every uploaded file returning the error "Max file size is 5MB." I've written the following code: Code: [Select] <?php echo '<img src="Sheph.png" />'; function Wad(){ if (file_exists("Sheph.png")) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename("Sheph.png")); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate'); header('Pragma: public'); header('Content-Length: ' . filesize("Sheph.png")); ob_clean(); flush(); readfile("Sheph.png"); exit; } } Wad(); ?> What I want to do is show the image AND show a file download window. The problem is that it shows the download window but the image doesn't appear. and if I comment the function and keep the echo part only,the image appears normally. What's wrong ? Hello! I'm making a interface in a website do manage files in a ftp hosted on other server. I'm using the function ftp_get() to download a file but I've tried different aways but I dosent seem do be able to download the file directly from the FTP server do the user the only way it works is if I download the file to the website server first then to the client. Is there any way that I can download the file directly to the user without have to hosting it permanently on the website server? Thank you Hi all, I'm trying to make a PHP script that downloads a file off a remote FTP server and serves the file to the visitor with a limited download speed. Right now I'm using fopen() like this: Code: [Select] $path = "ftp://".$username.":".$password."@".$server."/"; $fullPath = ($path.$fileName); $speed = 400; // 400 kb/s download rate header("Cache-control: private"); header("Content-Type: application/octet-stream"); //header("Content-Length: ".filesize($fullPath)); header("Content-Disposition: filename=\"".$fileName."\""); flush(); $fd = fopen($fullPath, "r"); while(!feof($fd)) { echo fread($fd, round($speed*1024)); flush(); sleep(1); } fclose ($fd); The file does download but with the wrong speed (8kb/s), does anyone know why? When I run the same code with a local file instead of a file on FTP it works fine and downloads at the speed I set it to.. Thanks The following code works fine when using chrome or firefox, but fails with IE. Error: Requested site is either unavailable or cannot be found. Question: Does anyone see anything here that is a known bug with IE that I don't know about? Code: [Select] public function download(){ if($this->validateFile()){ if(!headers_sent()){ header('Content-type: '.$this->getType()); header('Content-Disposition: attachment; filename="'.$this->name.'"'); readfile($this->file); } else{ echo 'Headers have already been sent and are preventing the file download from taking place.'; } return true; } return false; } //I felt this function might be relevant to the issue. I know, it's kind of a ghetto function, I'll improve on it some other time though. private function getType(){ $types=array( 'txt' => 'text/plain', 'mp3' => 'audio/x-mp3', 'jpg' => 'image/jpeg', 'jpeg' => 'image/jpeg', 'gif' => 'image/gif', 'png' => 'image/png', 'doc' => 'application/msword', 'swf' => 'application/x-shockwave-flash', 'flv' => 'video/flv', 'mpg' => 'video/mpeg', 'mpeg' => 'video/mpeg', 'avi' => 'video/x-msvideo', 'rtf' => 'application/rtf', 'pdf' => 'application/pdf', 'zip' => 'application/zip', 'exe' => 'application/octet-stream', 'xls' => 'application/msexcel', 'xlsxl' => 'application/msexcel'); if(!$types[$this->getExt()]==''){ return $types[$this->getExt()]; } return 'application/octet-stream'; } Hiya guys After getting everything else working how I expected, I'm sort of struggling on the last step. Downloading I have an upload.php file that allows me to upload a file to Mysql, the fields available a upid - Primary id - Need to link this to the logged on user id name type size content The upload works perfectly Can anyone help with implmenting it to the profile.php (1st page after login) On profile page I have: Welcome "username" from Session Dynamic Table display his user id, username and password at the moment, this will be changed as not needed tho. I am using the sessions MM_Username to pass from the login The table for Login looks like: id - primary username password I assume that if I can copy the ID from login and put it in ID in Upload and add colums to dynamic table to show the upload file, will this make that file only available to logged in user? Cheers Hello everyone! I'm somewhat of a newb in this so anyways I have this script and I try to force a browser to download a file when someone hits a download button. here is what I'm trying: header('Content-Type: application-download'); header('Content-Disposition: attachment; filename=' .basename($dl_id)); readfile($dl_id); It seems to work in Chrome, Firefox, but it doesn't work in IE Any suggestions? Hi there, I have a cronjob for PHP which generates a table with dynamic data and this table is exported to excel when run. When i have one table it downloads one excel file. I want to download multiple excel files using a for loop. Please Help... Any suggestions will be helpful.. Thank you, Regards, Rohit I'm wanting to have users able to download a file, but I'm wanting it to be a file that only users who are logged in can download. Basically, I don't want a user to be able to enter the URL and download it while not being logged in. Does anyone know what I would use to do this? Thanks. Hi PHP freaks!!
I have manage to make a script to upload file in database and its working. I will share to you the codes so for other viewers and readers to use also.
if($result){
if($_FILES['LRCard']['name'] != ""){
$filename = $_FILES['LRCard']['name'];
$ext = strrchr($filename,".");
$LRCardname = $student_id;
$LRCardname .="_". $filename;
if($ext ==".jpg" || $ext ==".jpeg" || $ext ==".JPG" || $ext ==".JPEG" || $ext ==".gif" || $ext ==".GIF"){
$size = $_FILES['LRCard']['size'];
if($size > 0 && $size < 5000000){
$archive_dir = "LRCards";
$userfile_tmp_name = $_FILES['LRCard']['tmp_name'];
if(move_uploaded_file($userfile_tmp_name, "$archive_dir/$LRCardname")){
/*
if LRC is successfully uploaded then LRC is stored in database.
*/
mysql_query("update student_information set LRCard='$LRCardname' where student_id='$student_id'", $link_id);
$flag = "success";
if(mysql_error()!=null){
die(mysql_error());
}
}
else{
if(file_exists('LRCard/' . $LRCardname)) {
unlink('LRCards/' . $LRCardname);
}
rollbackData();
}
}
else{
if(file_exists('LRCards/' . $LRCardname)) {
unlink('LRCard/' . $LRCardname);
}
rollbackData();
die("You can upload LRCard of 5 MB size only. Please, try again.");
}
}
else{
if(file_exists('LRCards/' . $LRCardname)) {
unlink('LRCards/' . $LRCardname);
}
rollbackData();
die("You can upload LRCard of .jpg, .jpeg, .gif extensions only. Please, try again. ");
}
}
}
else{
$flag="error";
}
if($flag == "success"){
mysql_query(" COMMIT ");
$flag="success";
if(mysql_error() != null){
die(mysql_error());
}
}
Now, my problem is how to make a Php script to DOWNLOAD this uploaded file considering the
1. file path
2. file name
3. file extension.
4. student_id (to determine the specific file from a specific student)
My plan is to make a download button which hyperlink to download.php and after clicking that button the specified file to a specific student id will automatically be downloaded by the browser.
