PHP - Moved: Download Starting Problem

I am using a script for users to download a file, however after the download I want to be able to
redirect the user or display a message etc... but I cannot get it to work.

My download code is below;

if($do_download){

 $filename = 'file.zip';
 $itemfile = ('/abc/123/htdocs/bin/'.$filename);
 $filelength = filesize($itemfile);

 $fp = @fopen($itemfile, "rb");

ob_start();
  Header("Pragma: public");
  Header("Expires: 0");
  Header("Cache-control: private");
  Header("Content-Type: application/x-zip-compressed");
  Header("Content-Transfer-Encoding: binary");
  Header("Content-Length: $filelength");
  Header("Accept-Ranges: bytes");
  Header('Content-Disposition: attachment; filename="'.$filename.'"');
  Header("Connection: close");
ob_end_clean();
  while(!feof($fp)){
  print stream_get_contents($fp); // for PHP 5+ else use fread
 }
 fclose($fp);

 header('Location: page2.php');
}

It doesn't seem to matter what I do whether a redirect or just an echo command nothing continues after the file is downloaded????

Hi,

I have one webhost (A) that supports no PHP and has unlimited bandwidth.
I have a second webhost (B) that does support PHP, but has limited bandwidth.

The website is on host A and contains a 5mb file that people can download and I'd like to count the downloads. But now I need to use host B to count the downloads.

I'm using this small script on host B to count the downloads.

<?php 
$hits=file("count.txt");
$hits[0]++;$fp=fopen("count.txt","w");
fputs($fp,$hits[0]);
fclose($fp);
header("Location: http://webhost-A.com/files/download.zip");
?>

The download link people see on my website is: http://webhost-B.com/download.php

Generally this works fine, but I found out that people can still find the direct link with download managers and then put that direct link on their website, which prevents me from counting those downloads.

A solution I found is to use ReadFile. But the problem is that when using ReadFile, host B first downloads the file from host A and then sends it to the user and that's exactly what I don't want.

Is it possible to let people download the file directly from host A without showing the direct download link in any way and also count the downloads?

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

started learning php yesterday at w3schools was looking for a great forum to ask questions as i go along. bumped into phpfreaks. looking forward to mastering the art

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

 

I can't for the life of me understand how to perform this so I need some professional help here.

I have a large array that contains some garbage every Nth and Nth + 1 element that needs to go away. array_filter doesn't work with keys but anyhow, i wouldn't know how to design the function.

My keys are numeric, starting from 0. The keys I want to remove are part of this sequence: 8, 9, 18, 19, 28, 29 ...

Can someone help me design a generic function to remove these keys?

function filter_keys($array, $n, $offset) {}

$new_array = filter_keys($array, 10, 8 );

I would maybe have to run this function twice, once for 8 offset and once for 9 offset.

So I started learning how to code php with usercake. I then went to use different things like fileNice for directory listing and I went to make a music lister with music player running mainly (EDM) .mp3's. I have uploaded a copy of my music.php file and I would love some help on how to develop my site further!   https://github.com/3...aster/music.php   This is the part I need help developing:

<?php

  function getUploadedFiles($directory){
    $folder = opendir($directory);
    while ($file = readdir($folder)) {
    if($file !== '.' && $file !== '..')
    {
        $filename = $directory.''.$file;
        $file_array[] = array('filename' => $file);
    }
}
return $file_array;
  }

$music = getUploadedFiles('../Music/EDM');

foreach($music as $value)
{
	echo '<div class="well well-sm">';
	echo '<li class="list-group-item list-group-item-success"><div class="alert alert-success" role="alert"><a href="../Music/EDM/'.$value['filename'].'"title="Play .$value" class="sm2_button"></a> '.$value['filename'].'</div></li>';
	echo '<p><a href="../Music/EDM/'.$value['filename'].'"><button type="button" class="btn btn-sm btn-primary"><span class="glyphicon glyphicon-headphones"> </span>&nbsp; Listen</button></a>&nbsp;';
	echo '<a href="../Music/EDM/'.$value['filename'].'" download><button type="button" class="btn btn-sm btn-success"><span class="glyphicon glyphicon-cloud-download"></span>&nbsp; Download</button></p></br></a></p>';
	echo '<p><a class="btn btn-default" href="#" role="button">View details &raquo;</a></p>';
	echo '</div>';
	}

  ?>

I would love to figure out how to use "echo '<p><a class="btn btn-default" href="#" role="button">View details &raquo;</a></p>';" to show time of when song was added, so Time last modified ?  Hopefully I can learn how to set individual counters instead of them being the same for all the songs :/     Here is a link to the site with everything running: http://thebatcave.x10.mx/dev/music.php Tell me what you think ?

I am starting a project that will encompass the following-

A forum script that will later be tied into it's own custom content management system.

But I have some questions before I get too deep into starting:

1. What is the "most" secure way to code a forum system?
2. Shall I rely on 1 person to code or open it to the public to help too (open source)?
3. Which features of forum scripts do you like and why?
4. How should the plugin system (hooks) be designed?
5. Template system - what is the easiest way to make theming simple?

These are just some of the basics that I am pondering at the moment. I know these may sound noobish but I would rather start this project the right way, instead of having it coded wrong etc.....and having to re-do everything down the road.

But I need help in an issue I have been having for awhile now. Some reason when I try to call for online status it does not work sometimes i can get it to show the default code 1 which means online. But I am trying to get it to say Online and Offline and so on. I do not get what I am doing wrong my website using mysql so not sure if its having trouble reading the database or what.  here is the code...

            break;

        }

        return $state;

    }
?>

This is basically my entire code that calls the steam api. Here is the echo function I use to try and call it on a profile.php page...

	echo "<br /><strong>Online:</strong> " . $steam->user['onlineoffline'] . " ";

So I would really appreciate it if someone can help me. I been trying to figure out this for the past week and its starting to drive me nuts and loose motivation on my project. Everything else works great minus this one issue. I have pretty much asked everywhere I can think of and no help. I use a function to call my database hint the global $DB; in my functions just to give you anymore information I can. $steam variable I believe is coming from my class at the very top of my code that is were $steam comes from.   Thanks

good day dear PHPFreaks - hello  to everybody.


i want to create a link parser. i have choosen to do it with Curl. I have some lines together now. Love to hear  your review... Since i am new to programming i love to get some hints from experienced devs.

Here some details: well since we have several hundred of resultpages  derived from this one: http://www.educa.ch/dyn/79362.asp?action=search

Note: i want to itterate over the resultpages - with a loop.

http://www.educa.ch/dyn/79376.asp?id=1568
http://www.educa.ch/dyn/79376.asp?id=2149


i take this loop:

for($i=1;$i<=$match[1];$i++)
{
  $url = "http://www.example.com/page?page={$i}";
  // access new sub-page, extract necessary data
}


what do you think? What about the Loop over the target-Urls?

BTW: you see - there will be some pages empty. Note - the empty pages should be thrown away. I do not want to store "empty" stuff.

well this is what i want to. And now i need to have a good parser-script.

Note:  this is a tree-part-job:

1. fetching the sub-pages
2. parsing them
3. storing the data in a mysql-db

Well - the problem - some of the above mentioned pages are empty. so i need to find a solution to
leave them aside - unless i do not want to populate my mysql-db with too much infos..

Btw- parsing should be a part that can be done with DomDocument - What do you think? I need to combine the first part with tthe second - can you give me some starting points and hints to get this.

The fetching-job should be done with CuRL - and to process the data into a DomDocument-Parser-Job.
No Problem he But how  to do the DOM-Document-Job ...

i have installed FireBug into  the FireFox...

now i have the Xpaths for the sites:

I am wondering whether there is a way to do a foreach loop for an array, without starting at index[0].  Say, for example, I wanted to start displaying the contents of a 20 item array starting at index 5, what is the best way to do it?

I know of this way, but it seems too crude (ie. there has to be a better way):

$count = 0;

foreach($array as $item)
  {
  if ($count > 5)
    {echo $item;}
  $count++;
  }

Any other ideas??

Why do I get the following results (specifically the second example)?  I thought it would be documented under https://www.php.net/manual/en/language.types.string.php, however, the word "ampersand" doesn't appear.  Also, looked at logical operators, but found nothing.  Thanks

function test(string $string){
    printf('%s %s %s 0'.PHP_EOL, gettype($string), $string, $string==0?'==':'!=');
}

test('123');
test('@123');
test('1@23');
test('123@');

Quote

string 123 != 0
string @123 == 0
string 1@23 != 0
string 123@ != 0

 

Hey guys just thought I'd introduce myself as it's a polite thing to do. My name is Nick I am currently a front end developer and love learning new technologies so it looks like PHP is my next step.   I hope to learn and give whatever knowledge I can back

well what is wrong here...?

Im trying to make a script that draws the track for a game that i in development, Im stuck on something though.

For some reason my script is drawing lines from 0,0 to the x,y of the start position to the x,y of the end position. I have no idea why.

Here is the script

<?php
    header ("Content-type: image/png");
    $im = ImageCreate (700, 400);
    $background = ImageColorAllocate ($im, 255, 255, 255);
    $line = ImageColorAllocate ($im, 0, 0, 0);

    $trackcode = file_get_contents('test.txt');
    $type = split("#", $trackcode);
    $line = split(",", $type[0]);
    $sline = split(",", $type[1]);

    for($i=0; $i<count($line); $i++)
    {

        $section = split(" ", $line[$i]);
        for($j=0; $j<count($section); $j+=2)
        {
$startx = base_convert($section[$j],32,10);
$starty = base_convert($section[$j+1],32,10);
$endx = base_convert($section[$j+2],32,10);
$endy = base_convert($section[$j+3],32,10);
//echo "startx: $startx | starty: $starty | endx: $endx | endy: $endy  <br>";
imageline ($im,$startx,$starty,$endx,$endy,$line);
        }

    }

    ImagePng ($im);
    ImageDestroy ($im);
?>


You can echo the data if you want to see the raw coordinates.

You will need to make a file called test.txt and put this in it for it to work
