Thanks OK, I have checked my phpinfo(); and the *session.use_trans_sid* = 1 ; *session.use_cookies =* On, so I'm not sure if I need to turn the cookies bit off, but I would think it not to be necessary. ; So, I can't see why the URL's aren't changed on my pages... Now, something to contemplate so long; say I DO get the URL bit right, what method does PHP use to determine which URL's to append? Would this method have a considerable overhead on performance? ( given that there could be alot of session usage on my domains). I'm rather interested in the workings of this URL "detection", as it basically means that PHP runs forward through all my pages to see where the session stops and and it's difficult for me to see how PHP can tell which pages have to do with which sessions. Arguably one can have two session "threads" that has some overlapping files, and my mind boggles as to how php can track the session vars, secially if the one session thread were to use the same session variable names ( which is surely possible right?) I guess my question is very academic, but I'm trying to understand the workings of sessions.. But for now, my main concern is getting PHP to work it's magic with my URL's.

Thanks

It's worth pointing out that enable-trans-sid IS NOT bullet proof. It doesn't work on all javascripts (or any other client-side scripting, and I'm sure there's some other scenario's that it skips.

It takes care of relative URLs within standard HTML. I have a feeling it doesn't work in IFRAME's, but does for FRAME's.

It worth doing some testing if you go down this road.

Was PHP compiled with --enable_trans_sid or whatever flag is it??

Yeah, it would affect performance. Not sure how much. I imagine that's why you actually have to set a compile time option to enable this.

PHP knows it has to deal with sessions when you call session_start() at the beginning of the page.

No, session names are unique. That's the whole idea...I use your unique session id to identify you each time you return to my pages.

That error is usually an indication that the particular resource hasn't been included when php was compiled.

Use phpinfo() to see what capabilities your installation has.

I seem to remember some discussion about this ages ago - there was some difference between how ErrorDocument works in httpd.conf and .htaccess - you might try the latter and see if there is a different result.

Then again, I might not be remembering correctly, so ...

I browsed the the apache source, and it looks to me that the message body is simply read and dumped into the bit bucket on a 404 with an ErrorDocument (and thus isn't passed as part of the internal request to the ErrorDocument itself). Perhaps you ought to ask the apache list.

Apparently, as I do read http://www.geocrawler.com/archives/3/182/1999/4/0/1646542/, it's an Apache problem.

Joakim,

Thank you for your reply. I tried your example and get 'Possible file upload attack: filename.' meaning that 'if (is_uploaded_file($_FILES['img1']['tmp_name']))' returns false. I put a couple of echo statements in before the if statement to check '$img1_name' '$img1_size and '$img1_type' and these all returned the correct values. I have my upload_tmp_dir in php.ini set to /var/www/html/img and this folder has 777 permissions. Do you think the file is not getting to temp directory and if so any idea why?

Have you tried echoing $_FILES['img1']['tmp_name'] or $HTTP_POST_FILES['img1']['tmp_name']? If the first doesn't work, you may have to exchange $_FILES to $HTTP_POST_FILES or $_FILES['img1']['tmp_name'] to $img1_tmp_name etc.

Joakim,

Thanks again. $HTTP_POST did the trick. I did look through the archives before posting but didn't come across this solution. I obviously didn't look hard enough!

attached mail follows:

Wouldnt this work? <form name=myForm action=sendPage.php action=post> <script language = javascript> function myFunc(){ var myJavaScriptVar = initialValue... ....Do What Ever (manipulate myVar)...

document.myForm.fieldName.value = myJavaScriptVar;

</script>

<?php // If the function my Func has been executed you can do // the following... echo "<input type=hidden name=fieldName value=$fieldName>"; ?>

// If you are not running apache (if running IIS) you may get an undefined // variable notice on running your script to rid yourself of // this do the following instead of the php above... <?php if(isset($fieldName)){ echo "<input type=hidden name=fieldName value=$fieldName>"; } ?>

Hope this Helps...

[snip] Chris, thanks for describing your method. The reason I really dislike Functions in PHP is because you have to pass every variable needed by a function, even if that variable is global in the main script, which is a pain in the ass when a function needs a long string of variables. It makes it easier to forget a variable in the list and can make the code look messy.

So, that's why I prefer includes, because the code is operating on the same level as the main script and can easily use variables set locally without making them global.

I'll use a function if it only needs one or two variables passed to it, but, I find myself using more Includes than Functions because of the variable passing necessary. [/snip]

Includes vs. Functions? How about includes that have functions, which a lot of developers do. For instance, I have a function set up for database connections. I use it by including it with pages that require database connections. I think this probably should be Functions vs. Blocks of Code (that might be placed in an included file). Actually I see this as being potentially messier, IMHO. I will have to remember many variable names that are used in the included file, rather than passing variables I am using locally to functions with clearly thought out names. Example;

a. I need a variable to hold this standard deviation result. Since I do the stdv calculation in the block I included I need to go see what the name of the variable is and use that, so I don't muck up the code.

b. calcStdDev($myCurrentVariable); oh, I need one for here too so, calcStdDev($anotherVariable);

I just think that you are selling yourself short, and ultimately your code will be harder to document and maintain. Using blocks is OK, if that block can be 'functionalized' I say do it.

For efficiency in processing it really will not make much difference in an included file whether that file is blocks, or functions.

I'm really battling with this whole session thing. My first impressions are that cookies are OK, and really helps to make sessions workable and efficient, YET, from a developers point of view, I always play devils advocate, and I'm wondering about those stubbourne individuals out there who outright refuse cookies; rendering my application useless unless I code a "plan B" into my code; meaning I can just as well NOT use cookies from the start...

There was also debate on using I.P vs Cookies, I see from your address that you are based in S.A. meaning there is still numerous amounts of people set on dial up hence allocating someone a specific id via dial up would be totally out of the question (dial up IP changes)... Through the discussions I was convinced that Cookies are and ought to be the best way to go... Most people use IE/Netscape which does not ask if you want to accept or reject cookies like the browsers that are generic to Linux namely Konqueror and Lynx... Furthermore, I don't know too many people that scrimmage through their hard drive searching for Cookies to delete... besides most people (unless they have done a great deal of web programming) don't know what a Cookie is, so if they actually do get prompted to accept or reject a Cookie the odds of them Accepting are equal to the odds of them rejecting (probably even higher considering most prompts require a Yes)...

I'd say Cookies and Sessions are quite reliable... Well, they are the safest method I know to go about the problem of monitoring ones surfing habits... If anyone can think of another please post her up, I'd be curious to learn of it...

Cookies rely on client side. I never rely on the client for anything.

When it comes to examples of how to do things "The Right Way," I say go take a look at amazon.com. No cookies. No Java'sCrap. Works flawlessly.

I don't use cookies either due to the fact that some web browser block the cookies and some web browser's bug that affected the cookie.

A number of people have offered their opinion why cookies are a bad idea. As a developer new to PHP, if cookies are such a big a big no-no, how does one do effective session management without storing anything client-side?? Bear in mind that the browser is stateless and, the user can disconnect and reconnect in between fetching pages from your site.

Instead of Cookies, I use Sessions which is run on hte server side. So, I use the

--snip-- $salt = strtoupper(md5(uniqid(rand()))); session_id($salt); session_start(); header("Location: https://xxx.yyy.zzz/index.php?".SID."&init_login=TRUE"); --snip--

to create the identifer for an unique person. Then use the php script that take care of the session management such as logging the user out when time is up as an example. Another script was used to prevent the direct access attempt. Another script was used to detect whether the server have the user's identifier in the server, if not exist then would force the web browser to the login page.

As for the newbie, well, sometime they had to learn it from the pro. Although it would be nice if there is documentation somewhere.

If you want to assure that you maintain session across the whole site, appealing to the lowest common denominator, then hard code the SID to all relative URLs across the whole site, or write a URL function which you can just pass variables:

<A HREF="<?=link('page.php?stuff=things')?>">Click here</a>

I should've clarified that statement a bit... I had a dig through the PHP source, trying to figure out what they were doing, and amongst the tags I *think* they were searching for, I couldn't see IFRAMEs... perhaps what they were doing with FRAME covered it -- I didn't dig deep enough, and haven't recompiled to test.

> Leaving me to think that there > will potentially be people out there that will NOT be able to use the > application, that could lead to messy discussions between developer and > client...

Yup. Developer should perhaps offer the two alternatives, clearly outline the difference, and make an estimate of the difference in cost. Let THEM decide if losing 1% (or 5%, or 10% -- whatever) of their users is acceptable, rather than resting it upon your shoulders.

Same argument stands for relying on javascript, IFRAMEs, FRAMEs, whatever.

Well, if you're used to passing stuff around in a URL, then why not:

a) run some tests with enable-trans-sid b) develop a method you're comfortable with for passing SIDs around in the URL

If you want 100% accessability, forget cookies were ever invented :) While you're erasing stuff from your brain, throw out javascript too :D

You pass the session around in the URL

Something like <A HREF="page.php?SID">click here</a>, or you might build a wrapper function that does it for you:

<A HREF="<?=link('page.php')?>">click here</a>.

Yes, that's every internal (relative) URL on your whole site :)

It becomes a trade-off between the convent but unreliable cookies, versus the 100% accessible, but perhaps time consuming/tricky URL method.

As has been said on this list MANY times, just have a look at the big sites like amazon.com -- no cookies, no javascript, no reliance on client-side for anything. Take care of it all server-side, where you have a controlled environment.

We use but one cookie, for returning user recognition. That is, the sort of info your soft can survive without. As for passing values on the GET channel to iframes, we do it all the time and have never seen a single problem.

Problems with iframes are in that you consciously loose all users working on Netscape 4 (once you have 7 interrelated iframes on a window you cannot really expect to have 7 indipendent windows open *and* your site still usable. Lynx people are cut out too. If you want to support *everybody* you should work one one single page.

It's a customer's choice, obviously. Most customers do not give a damn about minorities (and so do not want to increase budgets to develop an alternate solution that will address a minor community).

What increased cost? If someone does the right thing in the first place, there's no cost. The developers are either gettting paid to develop something that works right in the first place or they're getting paid to develop something that doesn't.

Let's use your Iframes example. My client was using them. I replaced such with proper layout for local content and importing remote content through implode('', file()). How does that cost more?

Anyway, cutting out potential long term revenue by alienating potential customers is a bad business decision.

LOL, we are all but prostitutes, my dear :) we get paid to do exactly what the customer wants and *how* he wants it to be done. As for myself there are *many* of my customers choices that I would not use on a site of mine, but once I have written them a formal letter saying why I suggest doing something else in instead and have got a formal receipt I feel no longer interested in whatever they decide. I am only interested in another sort of *how*, that is *howmuch* :)

> Let's use your Iframes example. My client was using them. I replaced > such with proper layout for local content and importing remote content > through implode('', file()). How does that cost more?

Yes, since you have to replace something that is already in place. It means you spend mantime to do it. Besides, they love iframes, so let's give them iframes. All they want is a scrolling bar *within* a fixed graphical frame, and only an iframe can do that.

> Anyway, cutting out potential long term revenue by alienating potential > customers is a bad business decision.

A one year long log shown that we are talking about 0.2% of their potential audience (and we include *my* verifications, which amounts to half of the events). Such decisions are not taken just like that. They watched the data and decided that 0.2% isn't worth a dime (and a minute) of theirs. It's their right to decide it.

Site targets a very specific audience (that is, the dental market). I don't think many a dentist will surf on Lynx, personally. And dentists just love to show their money, so I cannot think of a dentist using Netscape 4 and a 640x480 monitor.

I do (sometimes), you do, but we belong in a minority. Linguistic minorities make much more profit than browser minorities will ever do, simply because they make larger numbers. Having a site translated in french is making *much* more money than having it work on Lynx, believe me :) The good thing for them to do is have their site translated in as many languages as they can. That's from a profit-oriented point of view (mine too, since I sell language repositories as well) :) Europe is *not* america. Browsers here aren't a commercial issue, but local cultures are.

After all, if you and I are clever enough to use Lynx, we are also clever enough for us to download Mozilla and surf like standard people do, right? :)

Means your array doesn't have that key in it. I bet you're running into blank lines in your file.

Uh, you do realize that you're flip flopping the data around here for no reason. file() already creates an array. But you go through the unnecessary steps of compressing that array into a string and then recreating a new array. Just do this:

$Data = file($LookupURL);

That will eliminate your errors by not adding extra blank lines.

But, your whole approach is wasteful. As I said yesterday, use fopen() and then fgetcsv(). Forget the file() and split() calls.

Then, you're wasting time and memory with the list(). Use the resulting array directly.

while ( $Line = fgetcsv($fp, 500) ) { echo "<tr> <td>$Line[0]</td> <td>$Line[1]</td> ... etc ..."; }

Or, since you're pringing everything out, you could just do this:

while ( $Line = fgetcsv($fp, 500) ) { echo '<tr><td>' . implode('</td><td>', $Line) . '</td></tr>' }

My guess is that there is no ',' in $Line, so split returns an array with one variable, so list() warns you parameter No. 1, 2 ,3 4 and 5 are not asigned any value.

Hey thank Dan, I will try this. Does List waste lots of time and memory?

Normally, I create a function and global a bunch of variables to be used later on the HTML/PHP file. After I global the variables I split the string using the List function. I do that for stock quotes from YAHOO so I can code the layout in like Dreamweaver and place the varaibles where I would like instead of the function writing out the html for me. Is that bad?

It does if you don't need to do it.

Just put the data you really need into memory. Forget about the rest.

If you already have something in memory, don't duplicate it.

If you're globaling the variables, why not just write the code without enclosing it in a function?

In general, it makes sense, but, does it make the most sense. Depends on the situation.

But, in this situation, you're printing out a whole table of the data, so your way doesn't make sense.

A: No. Q: Is okay to top post and/or quote the entirety of the a post?

More detail? I have successfully make the data transmission work through php and curl without xml. I just barely gotten started on xml. I read the documentation about how it work, but it is only for the client side. I'm going to have to read some documentation and figure out how to use xml in php then figure out how to use curl for xml transmission. It is not just setting up curl is the issue here since xml and transmit through and back without the problem as I read on the cURL website. I have two URLs to deal with. The 1st for authentication and the 2nd, a completely different URL address for transmitting data. The odd thing is I don't need to have the encryption packages since the letter said all I need to do is to issue the key to that website and it will provide the encryption to me. Must be related to the authentication stuffs.

Ha! They can have at it! If they are stupid enough to spam a bunch of programmers and network people they deserve what they get.

Now it's *against the law* to harass spammers by tracking their malicious activity back to it's source and sending virus after virus : ), or hacking into their servers to delete things : ).

So I would *never* recommend that course of action.

But tempers do flare from time to time......... and there's no telling what a bunch of aggravated programmers can/would do.......

We're all here volunteering, trying to help each other out. If you want an instant response, hire someone. Otherwise, you need to be patient.

Sure, if you don't get a reply in a few days, your request probably slipped through the cracks, post again. But, in this case, you're being unreasonable: First post was at 10:00. Second at 11:58. Third at 13:16.

Posting to the list multiple times makes the list less pleasant for the people trying to help and those trying to learn.

You still need those lines in the newer version if you want PHP to work.

I have a problem similar to urs but with engine only. I used to set engine=off in php.ini and in httpd.conf as per vhost I add the following php_flag engine on. Since I upgraded to Apache 2.0.36 and php 4.2.1 it breaks the apache and complains that there is type mistake. I changed it from php_flag to php_value but no help at all. My workaround was to comment the lines in conf.d/php.conf that handle the php files through the php module and to add them per vhost and it worked. Also I tested the old AddType and it is working too. Regards

Make a script with phpinfo() in it and examine which php.ini file is being used. Sounds like you may be accessing the wrong file, even though you're saying you're not.

Are you making the changes in php.ini and _then_ restarting Apache? If not, you need to.

This will give you the date exactly seven days ago, then you can test what day (Mon - Fri). If it is Saturday then you could subtract 24 more hours, if Sunday, 48 more hours.
