I have a page, but I do not want it when I click on files of type .txt to download, instead of displaying them. I'm developing this page in PHP.

I have seen some script on the WEB, however it is forcing the download of .txt files without it being at least clicked on.

Here is the code I'm doing:

<html>
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9"/>
    <meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>
    <title>FTP</title>
    <link rel="stylesheet" href="css/style.css" />
</head>
    <body>
        <?php
        if(isset($_GET['path']))
            $dir =  $_GET['path'];
        else
            $dir = '..'. DIRECTORY_SEPARATOR .'ftp';
        foreach (new DirectoryIterator($dir) as $file) {
            if (!$file->isDot()) {
                if ($file->isDir()) {
                    echo '<div class="pastas">';
                        echo '<a href="index.php?path='.$dir. DIRECTORY_SEPARATOR .$file.'"><img src="icones/archive.ico" width="30px" height="30px"/></a>' . $file->getBaseName();
                    echo '</div>';
                } else {
                    switch($file->getExtension()) {
                        case 'txt':
                        echo '<a href=""><img src="icones/text.ico" width="30px" height="30px" /></a>'.$file->getBaseName();
                        break;
                        case 'jpg':
                        echo '<a href=""><img src="icones/jpg.ico" width="30px" height="30px" /></a>'.$file->getBaseName();
                        break;
                        case 'gif':
                        echo '<a href=""><img src="icones/jpg.ico" width="30px" height="30px" /></a>'.$file->getBaseName();
                        break;
                        case 'docx':
                        echo '<a href=""><img src="icones/doc.ico" width="30px" height="30px" /></a>'.$file->getBaseName();
                        break;
                        case 'doc':

To force a download of txt files I would use the function just below:

Code:

function download($arquivo){
      header("Content-Type: application/force-download");
      header("Content-Type: application/octet-stream;");
      header("Content-Length:".filesize($arquivo));
      header("Content-disposition: attachment; filename=".$arquivo);
      header("Pragma: no-cache");
      header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0");
      header("Expires: 0");
      readfile($arquivo);
      flush();
}

Code Usage:

download('forca_download.txt');

References:

Obs: It would be a way to not configure anything on the server transparently, and that works on all servers, which often does not let you change the settings.

The input string was not in an incorrect format. Is it a bad practice to make this comparison?

Second this post , you can do this by changing the .htaccess file with the following:

<FilesMatch "\.(?i:txt)$">
  ForceType application/octet-stream
  Header set Content-Disposition attachment
</FilesMatch>

This causes all text files to be served with the headers:

Content-Type: application/octet-stream
Content-Disposition: attachment;

According to this SOEN response , to use the htaccess header definition feature, it is necessary to activate a module from the Apache.
