PHP - Curl Download Zip And Unzip It

This topic has been moved to Miscellaneous.

http://www.phpfreaks.com/forums/index.php?topic=342772.0

Basically I would like to place a link on my website and have the user download a file, but rather than just right clicking and choosing save target as, the link must be clicked, on the next page the file is fetched and then the client can download the file. How would I go about setting this up please?

When the download appears the link that is produced doesn't show the actual download either, so users can't leech of it.

Thanks

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

I look forward to your ideas.

I have made a Php program that downloads an Inno setup installation file for installing a program. However, if I for one or another reason want to make a new download of the same Inno setup installation file, the previous file will still be found in the Download folder. Each of the downloads get a number in parenthesis, setup(1), setup(2), setup(3) etc. However, I wondered if it is posible to erase the previous file in the same process as I download a new one, so that however many downloads I do, there will all the time only be one occurence of this file in the Download folder.

The download code is as follows:

$exe = "Inno script/Test_setup.exe";
	header("Content-Type: application/octet-stream"); 
	header("Content-Disposition: attachment; filename=\"Test_setup.exe\""); 
	header("Content-Length: " . filesize($exe)); 
	readfile($exe); 

Thanks in advance.

Sincerely

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

Little help please?

1. I tried downloading a .txt file on mywebsite but it turned out to be viewing the text file, works on .doc files though
2. Can i have a string variable saved to a file to be downloaded in textfile (.csv)

algorith would be like this
csv_value = "1,2,3,4,5,6,7,8,9,0";
downloadlink(csv_value,file_name.csv);


PS. I used output_buffering = true on my php.ini so i have a little problem if your to suggest to use the header() function. unless there is another loophole. thanks in advance yours truly

i need a php script for download the enire directory with the files . i need a script for that ..

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

I have a small program that is to be used to export data from some MYSQL tables into an Excel spreadsheet.

It does the export successfully, the first pass, but each subsequent download selection causes the browser to display the html code as text to the browser.

If I disable the excel output, the page redraws successfully un subsequent requests.

The header definition I have is ias follows:
Code: [Select]
$FileInfo = pathinfo(filename);
            // fix for IE catching or PHP bug issue
           
            header("Pragma: public");
            header("Expires: 0"); // set expiration time
            header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
            // browser must download file from server instead of cache
            // force download dialog
            header("Content-Type: application/force-download");
            header("Content-Type: application/octet-stream");
            header("Content-type: application/x-msexcel");
            header("Content-Type: application/download");
            // use the Content-Disposition header to supply a recommended filename and 
            // force the browser to display the save dialog.
            if ($download_filename == "")
                $download_filename = "download.xlm";
            header("Content-Disposition: attachment; filename=".$download_filename.";");
            header("Content-Transfer-Encoding: binary");
            header("Content-Length: ".filesize($filename));
            @readfile($filename);

I did not setup this header, because to be honest, these things confuse the heck out of me. Can anyone see what may be wrong with this? Can you give me some suggestions?

I can post more of the code if needed, but i believe that this is the area of interest for this issue.

Thanks in advance.

Hi Guys,

I'm putting together a project which requires members of a site to upload files(mostly word files) into a mysql db.
I can get the files uploaded successfully but when it comes to downloading them i do have a bit of trouble. When i click on the download link i just get a file called 'download.php' instead of the actual file in the database.

I have been working on this link for the past two weeks and think maybe its time for some help, here's my code if you wouldn't mind having a look?




upload.php:

<?php

if(isset($_POST['upload1']) && $_FILES['userfile']['size'] > 0)
{

$connect = mysql_connect ("localhost","root","") or die ("Couldn't connect!");

$fileName = $_FILES['userfile']['name'];
$tmpName  = $_FILES['userfile']['tmp_name'];

$content = addslashes($content);
fclose($fp);

if(!get_magic_quotes_gpc())
{
    $fileName = addslashes($fileName);
}

$query = "INSERT INTO upload (name, size, type, content ) ".
"VALUES ('$fileName', '$fileSize', '$fileType', '$content')";

mysql_query($query) or die('Error, query failed');

I'm thinking that it could be something to do with the bin_data on the download.php page.
Any help would be great.

Thanks

Hello,

I made that script for previewing all the images in the directory:


Code: [Select]
$dir = "../images";
$images = glob($dir . "*.jpg");
foreach($images as $image)
{
echo $image;
}
Now what i would like to do is to put checkbox to every image. And when i press download button, all the selected images are downloaded. (as .zip, .rar)

Thank you very much for your help

Hi,
I don't want to reveal the real download link to my users for some reason, so I place the file here, for example:
http://www.domain.com/download/secure-file.exe
Now I want to write a simple php code and link to this address, for example:
http://www.domain.com/download/download.php
Now this php script read that file and send it to user, without revealing the real file location to user.
Of course there is no resume download now, but I don't care.
Anyone knows a code snippet for that, or can help me to the right position?
I am a newbie in PHP.
Thank you.
