cannot figure out permissions for fopen/fwrite
by Mari Masuda-2

Rate this Message:
Hello,
This is probably a dumb newbie question. I am running PHP 5.2.5 and Apache 2.2.8 on my Mac Book Pro OS X 10.4.11. I compiled PHP and Apache from source a while ago (as opposed to using the built-in web server that is included w/ Mac OS X). I have written the below PHP whose purpose is to read an existing comma separated (CSV) file and save the data into a text file that I can later copy and paste from into my website content management system. The problem is that on my Mac, I cannot seem to figure out what permissions I need to set in order to make the input CSV and the initially non-existant output text file readable and writable by Apache/PHP. I have Googled and come across many pages about different ways to set permissions and different permissions to set but none of the ways suggested that I tried seemed to work for me. As a temporary solution, I uploaded my PHP file to a Windows 2003 server running Apache and PHP and it worked flawlessly (and makes me suspicious that there is some huge security hole with the Windows box since it was able to execute with no permissions modifications). Any tips would be greatly appreciated. Thanks! Mari --- start my code --- <?php $in = fopen("/Applications/apache/htdocs/wp-php/wp.csv", "r"); $out = fopen("/Applications/apache/htdocs/wp-php/ tableToCutAndPaste.txt", "w"); $counter = 0; fwrite($out, "<table>\n"); while(($data = fgetcsv($in)) !== FALSE) { $paperNumber = $data[0]; $authors = $data[1]; $title = $data[2]; $filename = $paperNumber . ".pdf"; if(($counter % 2) == 0) { fwrite($out, "<tr>\n"); } else { fwrite($out, "<tr style=\"background: #cccccc;\">\n"); } fwrite($out, "<td><a href=\"http://www.example.com/workingpapers/ getWorkingPaper.php?filename=$filename\">$paperNumber</a></td>\n"); fwrite($out, "<td>$authors</td>\n"); fwrite($out, "<td>$title</td>\n"); fwrite($out, "</tr>\n"); $counter++; } fwrite($out, "</table>\n"); fclose($in); fclose($out); ?> --- end my code --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php |

Apache needs write permissions on that dir in order to create the file tableToCutAndPaste.txt. It's probably not a secure idea to give write permissions to that dir, so maybe create a subdir of tmp and change those permissions (one way): mkdir /Applications/apache/htdocs/wp-php/tmp chmod a+w /Applications/apache/htdocs/wp-php/tmp -- Thanks! -Shawn http://www.spidean.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php |

I also had to edit my .csv file in TextWrangler to change the line breaks from \r to \r\n before it would work. Although the Mac's built-in firewall is set to block incoming traffic except for network time and something installed by Adobe when I installed CS4, I was wondering about the security of this technique if done on a production server. I only run this script by pointing my browser to http://localhost/wp-php/generateTable.php and I think with my firewall settings nobody else would be able to execute this script, but it seems if the tmp folder is set to world writable on a production server that anybody might be able to somehow upload a malicious file if they knew the location of tmp. Any thoughts? Thanks! Mari -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php |

The tmp folder isn't accessible from the web though, right? Someone

Re: cannot figure out permissions for fopen/fwrite
by Mari Masuda-2
::
Rate this Message:
Yes, currently the tmp folder (or any folders in my Apache htdocs
folder) is not accessible to the web due to the Mac's built-in firewall set to block all incoming traffic except network time and something installed by Adobe when I installed CS4 (e.g., Photoshop, InDesign, etc.). However, I was wondering what the normal technique is for writing files if the script that does the fopen/fwrite is located on a production server that IS on the web. It occurred to me that I could create a 777 folder outside of the web root so that it would not be accessible on the web even if the script was running on a production server, but I wasn't sure if that was a good or bad idea.
