Text file on the fly for user to download using php
Here's the code for generating a text file on the file for user to download.
Make sure you don't have any output before this code, otherwise it will be shown on the downloaded file also.
<php? //Generate text file on the fly
header("Content-type: text/plain");
header("Content-Disposition: attachment; filename=test.txt");
$str="test";
echo $str;
?>
Restrict PHP Information Leakage
1 - To restrict PHP information leakage disable expose_php.
Edit /etc/php.d/secutity.ini and set the following directive:
expose_php=Off
2 - Do not expose PHP error messages to all site visitors.
Edit /etc/php.d/security.ini and set the following directive:
display_errors=Off
Make sure you log all php errors to a log file:
log_errors=On
error_log=/var/log/httpd/php_scripts_error.log
3 - Limit PHP Access To File System
The open_basedir directive set the directories from which PHP is allowed to access files using functions like fopen(), and others. If a file is outside of the paths defined by open_basdir, PHP will refuse to open it. You cannot use a symbolic link as a workaround. For example only allow access to /var/www/html directory and not to /var/www, or /tmp or /etc directories:
; Limits the PHP process from accessing files outside
; of specifically designated directories such as /var/www/html/
open_basedir="/var/www/html/"
; ------------------------------------
; Multiple dirs example
; open_basedir="/home/httpd/vhost/cyberciti.biz/html/:/home/httpd/vhost/nixcraft.com/html/:/home/httpd/vhost/theos.in/html/"

PHP CSV to Table
<?php
echo "<html><body><table>\n\n";
$f = fopen("so-csv.csv", "r");
while (($line = fgetcsv($f)) !== false) {
echo "<tr>";
foreach ($line as $cell) {
echo "<td>" . htmlspecialchars($cell) . "</td>";
}
echo "</tr>\n";
}
fclose($f);
echo "\n</table></body></html>";?>
