Re: [PHP] XML Parsing Problem
Huh - I guess it could be useful. I still think this should be an option you could set with xml_parser_set_option(), or something. In case anyone is interested, I solved the problem by creating a new global variable, $previousTag. Each time my character parsing function is called, it compares the previous tag to the current tag. If they are the same, the data gets stuffed into a buffer; if they are different, the buffer is returned, cleared, and the new data stuffed into it...and $previousTag is set to the current tag.

Re: [PHP] Updating Timestamps
The easiest way is to use an SQL query like this; update your_table set timestamp_field=null; This sets the timestamp to the current time automagically. You can of course add a where clause and so on to this query.

Kinda neat. But anyway, the timestamps are in one table, and when something is that table is changed, it automatically updates. However, I have another table which I want to affect the timestamps. Is there a command for 'manually' updating a timestamp rather than by SQL's own logic? Thanks in advance.

Re: [PHP] PHP priviledges
This is an excellent question. I've run into the same thing myself when setting up my own Linux boxen. Apache + PHP needs to have read access to users' web directories in order to serve them up to the 'net (mode 704), and directories must have the execute bit set (mode 705). Assuming users with virtual hosts are all members of a group (say 'vhusers'), a shell user cannot read other users' files. However, a PHP script (running as the Apache user - usually 'nobody') can read all files, obtain directory listings, etc etc (as can anyone not a member of the 'vhusers' group - on a virtual host server, I'm guessing no one should have priviledged access except the admins). Obviously, this is undesirable from a security standpoint. You don't want some luser snarfing the code you've been working on for weeks! One suggestion I've heard is to make each user have their own group, for example 'joeuser' belongs to the group 'joeuser', etc etc. Then you could start a seperate instance of Apache+PHP for each user - running AS that user. Now joeuser's PHP scripts can't read bobuser's files. However, in my view this opens up another security hole - external services should never run as normal users on a box. If a new buffer overflow was found in Apache, someone could easily wipe out joeuser's files...whereas in the previous example, the damage would be limited to just reading the files. Also, starting so many instances of Apache seems unnecessarily resource-intensive. I'm by no means a security expert - this email merely reflects the results of experimentation on my own boxen. If anyone has any suggestions on how to improve this situation, please post 'em!

Re: [PHP] need some ideas here...
If you have an account on a remote host, you can always do something like this: ?php include(http://www.remotehost.com/~myaccount/mailfunction.inc;); mymail($to, $mailbody); ? where mailfunction.inc has the mymail function defined to just take your parameters and stuff them into the standard mail(). Of course include()ing from remote hosts can be disabled when compiling PHP, and if your host is really evil, the will have disabled this too. Your last resort is to create your own mail function by fsockopen()ing a connection to port 25 of your SMTP server and sending raw SMTP commands. This would require some reading of the relevant mail RFCs...but is definitely feasible.

[PHP] PHP 4.0.5 Parse Problems
Hi all - Today I compiled and installed PHP 4.0.5 on my Linux server (Apache 1.3.19, linked statically with php mod_ssl). Suddenly, many of my files would no longer be parsed by PHP - instead, they spit raw code onto the page. I created most of the files on my MacOS X machine using the text editor Pepper. Some were also created on Windows 2000 using Notepad. Previously I noticed a post to this list noting a problem with line endings: With 4.0.4pl1 and earlier, this did not occur, but with 4.0.5, there are some files on our server that are not getting parsed as php, and just showing up as the code itself. The problem files are a mess, but I only mention them since they got parsed before. They are php files that the designers here have created in HomeSite and saved as PC format, so they are basically 1 long line when I open them in vi, and have ^M's everywhere. If they pull them back into HomeSite and save as UNIX format and upload, no problem. What changed in PHP that would make this difference. I would just tell them to do this with all the problem ones, but there are a lot. This is on OpenBSD, btw. Thanks. -Ken I tried changing the line endings of some of my files, but to no avail. The only thing that seems to work for me is to create a new file using vi or pico - PHP then parses it perfectly. For now, PHP 4.0.5 isn't a must-have upgrade, so I went back to 4.0.4pl1. Is this a bug, or some change in PHP that is causing it to ignore alternative (non-UNIX) line endings? If there is a problem with PHP, I want to make sure everyone is aware of it so it can be fixed in 4.0.6.

Re: [PHP] Retrieve item from table at random
I've got a better way yet: select RAND() as rand_col, column_name from table_name order by rand_col Only one query for randomized results, no PHP/Perl/etc. You can of course add the 'limit 1' on the end to get one row back.
