[PHP] Authentification and session management
Hello PHP-Community, I am PHP programmer since many years and over the years, I have reinvent the wheel in authenification and session management at least 30 times. Yeah, whenever a new project started, I had to reinvent the wheel. So my question now is, is there a proven and secure framework which can be used? My main problem is, that we (anything ISP related) authenticate using PAM+PostgreSQL while the normal Web-User stuff is authenticated directly with a Virtual-DB based on PostgreSQL. Another thing I like to implement in my scripts, that users can at there implicit choice be permanently connected without using a password. Also the script shoud detect, whether a user is connected trough a dynamic IP or a fixed one and sugegst a security level. I am already detecting the IP from the login and many customers (mostly from http://www.free.fr/) have static IP's.

If you touch() the file before you add it to the archive, then the new time will be used. But the phrase , so each file preserve its modified time, suggests that the modified time is NOT remembered. If so, I would consider that a bug. But, if you are using extractTo(), then you could use statIndex() to read the archive to find the modified time and then to touch() the created file with that time. -- - Richard Quadling Standing on the shoulders of some very clever giants!

Re: [PHP] Authentification and session management
Michelle Konzack wrote: Hello PHP-Community, I am PHP programmer since many years and over the years, I have reinvent the wheel in authenification and session management at least 30 times. Yeah, whenever a new project started, I had to reinvent the wheel. So my question now is, is there a proven and secure framework which can be used? My main problem is, that we (anything ISP related) authenticate using PAM+PostgreSQL while the normal Web-User stuff is authenticated directly with a Virtual-DB based on PostgreSQL. Another thing I like to implement in my scripts, that users can at there implicit choice be permanently connected without using a password. Also the script shoud detect, whether a user is connected trough a dynamic IP or a fixed one and sugegst a security level. I am already detecting the IP from the login and many customers (mostly from http://www.free.fr/) have static IP's. Why don't you take one of those wheels you created and make it work with a simple configuration and voila, you have a class or library that can be used in all your projects. It should be as simple as it sounds.

I see I need to specify what I'm really doing. Actually, I need to change the letters in the text. It's a famous and ancient crypting method: you divide the alphabet making two parts, then you change the letters of one part with letters for other part (so A becomes N, B becomes O, etc., and vice versa). it works fine and slightly with strtr or str_replace... but only if the text is not in utf-8 and it doesn't contain any non-English letters such as Cyrillic what I need. What my regex does is the following: it sees an A, well it changes it to N; then it goes through the string and sees an N... what does it do? Surely, it changes it back to A! I hoped (in vain) that there exists a modifier preventing this behavior... but it seems that it's false( Thanks! Hmmm, what comes to mind is using your string as an array and translating one character after another, building your output string using a lookup table. Not entirely sure how that will play with utf8 characters, you'd have to try and see. I don't think you'll get any of PHPs string functions to do the work for you - they'll do the job in serial, not parallel.

For example, a capital A is ascii 65, you want to change it to an N to add 14 to that. Just keep n the same throughout and it's easy to convert back. Thanks, Ash http://www.ashleysheridan.co.uk You probably overlooked the part where the OP points out he's not using ascii but utf8. If it was just ascii, using str_rot13() would be the weapon of choice I'd say (note that adding 14 to every character of an ascii string will turn lots of it into gibberish - you have to wrap round when you reach a certain point).

Also, is gibberish really an issue to worry about? The Caesar cypher is already rendering the string unreadable. You normally want output in the same range that you encode from (i.e. you're remapping within the alphabet, not within the entire range of printable characters) if you're doing a caesar/rot13.

HTML parsing is not that trivial. If the HTML you are parsing is malformed, things get worse. You may want to try this HTML parser package. It can parse HTML, CSS, DTD, etc.. in pure PHP. No special extensions required. It can tolerate malformed HTML and even filter insecure HTML and CSS that may contain dangerous Javascript.

A form with a input type=file/ element could handle the image upload and text part. If they need to upload multiple files then you could either use several input elements or a multi-upload option, although the latter aren't very accessible at all I've found, which seems to go against one of your requirements. I assume the need for multiple galleries, and further assume that you already have a way that you are distinguishing users. Just use this identifier against each image to denote a gallery. A database can easily be used here to not only identify the gallery an image belongs to but the user who uploaded it, and what galleries the user has rights to, etc. Creating thumbnails is also a doddle. I've just written up a function I wrote for http://www.vicestyle.com which creates thumbnails in any size you want from any image without distortion using a smart crop technique at http://www.ashleysheridan.co.uk/coding/php/Smart_Image_Resizing .
