[PHP] Need help in identifying a PHP application.
Hi, I have a need for an idea management PHP application that gives me an UI with multiple fields (text boxes, radio buttons etc.) which correspond to different columns of a MySQL database. An user initiates this by clicking on an URL, fills in certain fields and submits the form. This then creates the tables and should send out a mail to certain mail ids that there is a new entry. At a later point of time someone else can enter info into certain fields (columns of the tables) giving the same id as it was created. He should not be able to meddle with the original fields that user1 had entered. Another user can come at even later stage and enter info into a few more fields (columns of the tables). All these fields are created at the first stage itself since we will be fixing the number of fields. Can you let me know of any application that does all these? If this is a wrong forum to ask this type of question, can you tell me where I can post this query?

It just seems clutterd to me to have data in the database that doesn't actually have any database operations done on it. It also may add another thin security layer (defense in depth) to not have the documents available in the database, in case the database is penetrated.

Then it's taking everything after that, turning it into an integer and putting it in `number`. Then the ORDER BY works as you'd like because it's sorting on an actual number rather than a string representation of a number.

Dante Sorry, but no PHP threads can re-use any PHP classes, as threads are not implemented yet... maybe until PHP 8 :-) Threading isn't a trivial task, and if you MUST use it (I don't think so) you should develop some extension or take other approaches like embedding, and code all your threading needs apart from PHP, in C. But be careful interacting from that code to PHP. Or, perhaps switch to another language, if you can't cope with that. I've been developing desktop applications with PHP-GTK since 2002, far beyond the web script context, and in the more complex projects I did, was a must to implement multi-process and IPC communication due to the lack of threading in PHP, as to deal with some issues like multiple tcp clients, multiple tcp server with a proxy to the application data, webservices, handling UI, and a lot more stuff, while doing realtime (the more realtime I was able of) processing of all incoming and outgoing data, for more than 24 hours long running time. Yes, I was able to be successful with such a developement after a lot of pain, but it is not likely the most common usage for PHP. I finally had to implement several parts in C, embedding PHP, and really, I was not happy of to cope with that, but I did not have the time to switch to another language as I had to re-use a lot of existing code that worked smooth with a multi-process approach, but without the need of so long running time, so many tcp clients, and so many data... I had to implement data containers in using C structures, as handling all that data from PHP taken more than 500Mb of RAM in no more than 8 hours of processing, interprocess syncronization mechanisms, and a lot more stuff. In my case, multi threading was a real need I had to workaround. I think this is a real life example of PHP being expanded far beyond web paradigms or simple shell scripts, without any multi-threading support. But PHP is not thought in any case to be used for such applications... (I'm talking about desktop applications, not web script applications), with or without multithreading. If you'd like to use mt in your applications or web scripts, better switch to some other language, or search for alternative ways of implementation as you did with a multi-process approach.

Re: [PHP] New Help with Javascript Navigation
Interesting discussions... :) I see two issues: 1. if you are exposing php scripts to the client, how does the server side processing know what it should do and what the client should see? 2. and why can't JS write to the client's file system? Or read from files? Come to my website and let me first read all your private information, then trash it... Hackers and other cyber vandals would love you to implement this feature...

[PHP] Uploading pic
Hi, I have this problem with uploading images: I try several PHP classes for upload of files on server ( pictures in my case ), but if some user only renames some file as .jpg the script uploads the file even the file format is not .jpg - i.e. - file test.mpg - the user renames it to test.jpg - and the script upload it on server. Of course after this the website don't show any pi - it shows like pic does not exists. I need also to control the dimension of pictures ( in pixels), size in kb and type of files ( .gif, .jpg ). Is there a way to do this with some script ? Thanks, Rosen -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] I want to write a Multi-threaded PHP Application
I forgot to put some final note into my last message. PHP can be good for a lot of things, but not really for other. Wonder when requirements grow long in some ways you could not ever expect in a project like your's: A simple example: need 5 concurrent connections in your hacked multi-process server, that could be easily done in PHP, and, you could probably live with it in some circumstances. But do you wonder what could happen with your system if tomorrow you need to handle, let's say, 500 or 1000 concurrent connections? yeah, you will tell me that your software was not designed for that, or because PHP has no threading... Having that in mind, you must think seriously about the future of your application, because switching today can save you a lot of time waste tomorrow, like happened to me with one project. PHP was great for lots of projects I did, but if in the past I could only realize a bit of what I should have to do later, I definitely had switched immediatly before starting that developement, as I have done anyway later... the requirements for my applications grown more and gone far beyond what I ever expected... :-) but who knows that in advance? I continue using PHP for a lot of tasks, tasks I know in the future won't requiere me to climb a mountain, being over its limits... because it was not the right tool to use for the job. Hope my comments can help you in your thoughts of standarizing on a single codebase and language... :-) Gonzalo Gonzalo Monzón escribió: D. Dante Lorenso escribió: Gonzalo Monzón wrote: Use Python, it is the way to go if you're willing to use mt :-) I've already written the multi-threaded server using Java. I want to do this in PHP, however, because the PHP threads can re-use PHP classes I've already written and hence standardize on a single codebase and language. Many other languages have threads (Java, C#, Python, Ruby, etc) ... which is why I'm so amazed PHP does not even list Threads as a priority. You simply can't be an enterprise language without these basic features. Of course, don't get me started on namespaces too ;-) No, choosing a different language has been considered and I'd rather continue with my hacked multi-process PHP server solution before I am ready to change to a different language. Dante Sorry, but no PHP threads can re-use any PHP classes, as threads are not implemented yet... maybe until PHP 8 :-) Threading isn't a trivial task, and if you MUST use it (I don't think so) you should develop some extension or take other approaches like embedding, and code all your threading needs apart from PHP, in C. But be careful interacting from that code to PHP. Or, perhaps switch to another language, if you can't cope with that. I've been developing desktop applications with PHP-GTK since 2002, far beyond the web script context, and in the more complex projects I did, was a must to implement multi-process and IPC communication due to the lack of threading in PHP, as to deal with some issues like multiple tcp clients, multiple tcp server with a proxy to the application data, webservices, handling UI, and a lot more stuff, while doing realtime (the more realtime I was able of) processing of all incoming and outgoing data, for more than 24 hours long running time. Yes, I was able to be successful with such a developement after a lot of pain, but it is not likely the most common usage for PHP. I finally had to implement several parts in C, embedding PHP, and really, I was not happy of to cope with that, but I did not have the time to switch to another language as I had to re-use a lot of existing code that worked smooth with a multi-process approach, but without the need of so long running time, so many tcp clients, and so many data... I had to implement data containers in using C structures, as handling all that data from PHP taken more than 500Mb of RAM in no more than 8 hours of processing, interprocess syncronization mechanisms, and a lot more stuff. In my case, multi threading was a real need I had to workaround. I think this is a real life example of PHP being expanded far beyond web paradigms or simple shell scripts, without any multi-threading support. But PHP is not thought in any case to be used for such applications... (I'm talking about desktop applications, not web script applications), with or without multithreading. If you'd like to use mt in your applications or web scripts, better switch to some other language, or search for alternative ways of implementation as you did with a multi-process approach. PHP its a great language, but it isn't the right tool for anything. Gonzalo. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] php - js (was Javascript Navigation)
Hi gang: I changed the subject line, because I consider the topic important. Forgive me my simplicity, but trying to tie communication between php with javascript is like trying to get the past and future to talk to each other -- they exist at different times. Normally, php is history when js steps on the stage and while js may say a few lines to php (i.e., Alas Poor Yorrick, I Knew Him ...), there isn't any real dialog. Additionally, with regard to the web, their activations are different. JS listens and responds to user activities whereas php only responds to a limited set of prompts. Ajax appears to blur the distinction somewhat, but it's still nothing more than a call from js to php and js has no idea if php's task was successful, or not. In other words, there is no real two-way communication. To me, what's needed to combine these two languages successfully is simply communication, such as: 1. A way to send information from js to php and have php act upon it. 2. A way to send information from php to js and have js act upon it. Then one of the two languages (most likely js) would need to have some sort of repeating polling mechanism where instructions could be handled -- an event loop. When you have that, then you'll have the makings of a language that can develop real desk-top-like web applications. But, that's my view. tedd -- http://sperling.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Bug madness
Hi all, I have been mashing my head trying to debug a web app I have written, the deadline is tomorrow and after implementing some changes a subtle and difficult-to-pin-down bug has emerged. I am not going to include code as there is too much of it, but here is the general issue: The app consists of three linked forms and three modules that process the data passed in from the forms. All was sweet and perfect before today. The forms are self-reloading, and after the data is checked, validated and entered into the database the form is supposed to display a thank you section. As part of the processing process (!), the scripts assemble and send multipart mails to the entrants. Now, when I submit the forms, I see a blank page - nothing, no html, no error messages. I have added debugging functions at each point to track the logic and they inform me that the processing functions get to the end (where the mails are sent) where they should return to the caller (ie the form). This does not happen. I have display_errors enabled and cannot seem to locate the source of this issue. Ambiguous I know, but it may be a recognisable issue to many of you, in which case any advice would be greatly appreciated. I am extremely calm. -- http://www.web-buddha.co.uk dynamic web programming from Reigate, Surrey UK (php, mysql, xhtml, css) look out for project karma, our new venture, coming soon!

I am not going to include code as there is too much of it, but here is the general issue: The app consists of three linked forms and three modules that process the data passed in from the forms. All was sweet and perfect before today. The forms are self-reloading, and after the data is checked, validated and entered into the database the form is supposed to display a thank you section. As part of the processing process (!), the scripts assemble and send multipart mails to the entrants. Now, when I submit the forms, I see a blank page - nothing, no html, no error messages. I have added debugging functions at each point to track the logic and they inform me that the processing functions get to the end (where the mails are sent) where they should return to the caller (ie the form). This does not happen. I have display_errors enabled and cannot seem to locate the source of this issue. Ambiguous I know, but it may be a recognisable issue to many of you, in which case any advice would be greatly appreciated.

Normally, php is history when js steps on the stage and while js may say a few lines to php (i.e., Alas Poor Yorrick, I Knew Him ...), there isn't any real dialog. Additionally, with regard to the web, their activations are different. JS listens and responds to user activities whereas php only responds to a limited set of prompts. Ajax appears to blur the distinction somewhat, but it's still nothing more than a call from js to php and js has no idea if php's task was successful, or not. In other words, there is no real two-way communication. To me, what's needed to combine these two languages successfully is simply communication, such as: 1. A way to send information from js to php and have php act upon it. 2. A way to send information from php to js and have js act upon it. Then one of the two languages (most likely js) would need to have some sort of repeating polling mechanism where instructions could be handled -- an event loop. But Tedd, this is how so many web applications work now: PHP generates pages in which and on which JavaScript acts, and JavaScript helps direct to URLS, forms querystrings, and post form input back to the server. It's true that PHP can't know whether JavaScript will be running in the next page it delivers, so it has to generate pages that will be fully functional even if there's no one to talk to. It's easy to build in semaphores that let PHP know whether or not JavaScript was running in the page last posted, although as we know it should validate all the incoming data and not DEPEND on client-side scripting for anything. It's true that part of JavaScript's mandate is real-time user interaction which PHP can't touch, and part of PHP's mandate is file manipulation that JavaScript can't perform. So what? It's commonplace for different components of a complex system to have discrete functional domains. For what it's worth the two languages also share capabilities, such as creating and manipulating document elements, strings, and arithmetic calculations. The fact that their domains aren't identical is hardly a show-killer. To me, what's needed to combine these two languages successfully is simply communication, such as: 1. A way to send information from js to php and have php act upon it. URL, querystring, form input, and cookies. 2. A way to send information from php to js and have js act upon it.

Sorry for the length but... I haven't got the time right now to make it shorter. :-) The application I was talking about is not web-based but a PHP-GTK one, no server side scripting, only cli, so I guess we are in the same boat, yes, we are, but with very different needs and approaches. I'll say in advance that I was not able to use any SQL database server or web based processing for this application, due to project requirements... My application was mostly based on GTK timers and UI event callbacks. For inter-process comunication, I had to implement a lot of different approaches to ensure the best reliability. Some kind of processing requiered to use syncronized shared memory, other kind used simple win32api IPC calls... etc. Each kind of task requiered different approaches, for little data size overhead, for fast or low response times, and most of these are lot easier to implement using multi-threading and simple syncronization mechanisms, as I do now in my new developement environment, once switched language for almost all the system, with no more headaches or over complexities due to not be using the right tool for the job. I really had to switch language as I was not likely to improve more the system performance as to be able to evolve in the right way for the future -and i don't want to thought anymore about memory leaks issues I had to workaround-. I never thought I would need to evolve my system like to develop such a beast: once I finished that development and start to grasp and worry about what would be the next requirements for the system, I was afraid of: What will I do if do I must handle not 15 clients but 25? how many tcp servers? and perhaps not 150.000 registers but 300.000 per hour? yes, these requirements now are real. Before all these troubles, when my system only needed to handle 5 clients, 3 servers, no more than 10 processes, and about 65.000 registers per hour, for no more than 3 hours long, I had almost no headaches... and was quite happy using PHP... :-) I thought you people must say I'm a fool trying to use PHP for such a system... I never thought of developing such a system with PHP-GTK... until I had to do it for yesterday and haven't got the opportunity to say NO... lets do it the right way: use a language not designed for web scripting... we need multithreading and the speed of compiled code !! don't care if we need 6 months more for development !!! :-) Only real support for thread safety can avoid such a nightmare, but that dont seems to happen until... who knows?

I'm not trying to see, or create monsters, I'm just trying to understand. Sorry, that was my attempt to be light-hearted and disarming~ Tedd, it almost seems as though one of your requirements for PHP-JavaScript communication is that there be PHP and JS scripts running continuously trading bits of information back and forth. The web model is quite different, with scripts starting up and ending with each page-load. A full-page round-trip to the server, as when you click on a hyperlink or submit a form, is one complete cycle of client-server communication. It is possible to trigger smaller increments of communication as Ajax/XMLHttpRequest demonstrates, but still each time you talk to the server you're starting a PHP script running from scratch on the server. This wake up/go to sleep model doesn't disqualify it, in my view, from constituting communication between two scripts. To me, what's needed to combine these two languages successfully is simply communication, such as: 1. A way to send information from js to php and have php act upon it. URL, querystring, form input, and cookies. Okay, I understand how js and html can communicate with php -- but, that's not the problem. My statement above was part of a symmetrical requirement regarding communication. Sorry -- symmetrical? Please elucidate, I'm not familiar with this term in this context. Which factors need to be the same on both sides of the Turing box lid for your criteria to be satisfied? 2. A way to send information from php to js and have js act upon it. HTML, inline script blocks, dynamic script files, and cookies. But, show me an example of php doing each of the above where js will receive the data and will act upon it. Well, first of all, JavaScript acts in the context of an HTML page. When PHP generates the page, PHP is providing JS with all the elements and attributes necessary to conduct its business. If JavaScript submits a form with particular input name/value pairs, PHP can respond by selecting data from a table and/or branching in its logic tree and generating a particular set of markup on the next page for JavaScript to operate on. PHP can output HTML markup containing data for JavaScript to operate on. PHP can output script blocks into an HTML document containing executable instructions including static and array variable definitions. PHP can dynamically supply external JavaScript files, literally cooking the JS scripting logic from server-side. For example, if php creates a cookie, then how does js know that? How can the presence of a cookie cause js to run? Gecko DOM Reference DOM:document.cookie http://developer.mozilla.org/en/docs/DOM:document.cookie Also google javascript cookie e.g. http://www.netspade.com/articles/2005/11/16/javascript-cookies/ Can js cycle reading cookies waiting for something to do while php crons writing them as needed -- and vise-versa? Is that a viable method of communication and activation between the two? No, because cookie values are changed only on page submit load. To my knowledge, XMLHttpRequest is the only way for JavaScript to request receive PHP data during a single page-view. (Well, there is another way: JavaScript can create an Image object on the fly with a PHP script as the SRC and data on the quesrystring, but I haven't taken the trouble to cook up a scheme for PHP to deliver and JavaScript to extract information from an image bitstream so in my work this is a one-way communication channel.) This demonstrates that a single, continuously-executing JavaScript program can wait for responses from the server. The opposite is clearly true in principle -- the server's operating system waits for the next HTTP request from the client -- although I suspect that it would be excessively and unnecessarily burdensome on the server to have a PHP script continue to execute in anticipation of the next client request. Much more efficient to have the operating system wake up the PHP interpreter and execute a script only when one flies in the window. Is there anything that php can do that will initiate a js routine? As far as I know (limited as I am) php can't even detect if js is present, or not, let alone cause a javascript routine to run -- is that not correct? If not, please give me an example of where php can make js run. PHP can initiate JavaScript execution simply by downloading an HTML page that contains JS script set to execute immediately or on a given event. Every time JavaScript runs in a page generated by PHP, PHP is essentially telling the JavaScript interpreter in the browser to execute the contained or linked script. PHP can select a particular JS function to execute based on various criteria by downloading code to

Basically I want people to be able to pay for a speech and then be able to download it. it's the first time I wanna do anything like this, so I was thinking to myself to do it this way: when they pay for a file, I generate a session, that includes file name and username and is in md5 format. then I store this session to a mysql database. anytime the customer wants to click on a file to download it, I'll make the same session again and check the mysql table to see if it exists. if it does, then he can download it. the problem that I can think might happen is that the file names are not changable. you can't rename a file, and if you delete it, and add another file with the same name later, it'll give access to everyone.

If you feel you need that extra security then go for it, but be aware of the side-effects. -Stut -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Let me re-answer that. Yes, cookies are an acceptable method of PHP-JavaScript communication -- when they're turned on in the client -- but require a new page load to synchronize changed values between client server. When I said no all I meant was that cookies don't work for communicating PHP-to-JavaScript within a single page-view.

Re: [PHP] credit card purchase and downloads
Thank you very much Stut, great points. I didn't even think about wanting to display a list of files they have access to. I guess I'll go with the simpler way and save myself a lot of overhead. As I said, I've never made a site that had anything to do with money before, this is the first time. I just wasn't sure what kinda security I need. I guess as long as the credit card transactions are secured, I should be fine. thanks again, Siavash thinkQuoting Stut [EMAIL PROTECTED]: [EMAIL PROTECTED] wrote: is that really secure? I just thought if for any reason, someone can get into my database, they can't just add usernames and file ids to my table and have access. I thought if I md5 it, then it'll be more secured. would 1 table for username-fileid really be fine? If they get that level of access to you database then most bets are off. However, you are correct to a certain extent. If you one-way encrypt (if MD5 can be called encryption) all your data then yes it will be more secure, but to me that security comes at too high a cost from a functionality point of view.

There isn't something simpler, but that is necessitated by the stateless nature of the web, and the security requirements of the client (the poor sucker browsing the net :) I understand your desire for the simplicity of a desktop application, but anonymous data sources and trust aren't usually compatible. In the web paradigm the both the user and the server need to distrust one another by default which isn't the case for bought from a reputable, honest to goodness real live person, manually installed desktop application *grin*. Although, can't say I trust MS much. PS: WAHOOEY indeed -- LOL, I'm still chuckling about that. It was nice of PHP to let us name our heredoc delimiters.

Do you mean the way one function can call another function within the same program? It sounds like you're picturing PHP JavaScript executing continuously simultaneously. You aren't, are you? JavaScript can execute a PHP program at will simply by requesting a PHP page from the server. PHP can execute a JavaScript function at will simply by downloading it (with at least minimal HTML markup) to a browser. That seems pretty simple direct to me, considering that they're running in different computers. I can see how php can, and have used php to, generate a web page which has body onload=js() tag, which can pass a variable to js and will cause js to execute. But, isn't there anything else?

But, that appears messy to me. If php wants to say something to js, then a page must be created -- it seems like a lot foreplay to get at the goodies. Without a downloaded page, what goodies are there? You know, you can download pure JavaScript, dressed only in a script tag, to a browser and have it execute without carrying with it a whole HTML page. Is that what you're looking for? What would such a script accomplish that a PHP program couldn't? I suppose it could interact with the human user with prompts, alerts, and confirms; gather information about the client such as monitor window size; grab local time to compare to server time. What else? If it has to create DOM nodes to interact with the user, haven't you come full circle and shouldn't you just download an HTML page to be JavaScript's environment? I guess what I'm looking for is something simpler -- is there? Paint me a picture of a hypothetical simpler situation; I'm intrigued.
