Sorry forgot to mention how you show errors on a particular page- you
would use-
ini_set('display_errors', '1');
But are you sure you want to do this? Showing errors to your users is
NOT a good idea as it can open your server up to all kinds of security
issues. Why not use the log parser idea that I said in my last mail?
I didn't get that last e-mail, and I'm on a design web server, not an

Re: [PHP] Browser displays blank page, while request still being handled
Do you have short open tags allowed in this server setting? why not just do ?php print $_REQUEST[result]; ? Yes, short open tags are allowed on this server. As mentioned before, all instances of this app are running on the same server, using the same configuration etc. Differences between the problem app and the other apps are the number of files (and megabytes) and number of db-records, which are both a lot more than in the other apps. Tried to use your idea, but it doesn't solve the problem... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Browser displays blank page, while request still being handled
The script behind the request does the following: - delete some files - copy files from dir A to dir B - read some data from a database and generates some XML-files (i.e. a basic publish procedure) The problem isn't the script itself, nor the server. I know this, because the same code is being used on the same server for other instances of this application. Take this view-point, to keep your sanity: The script is buggy, always has been buggy, but is only now exhibiting noticable behaviour of the bug. Which is painful, but better than the Voodoo of a script that is fine except sometimes it's not. The script has most definetly always been buggy. The only reason why we weren't seeing this behaviour before, is because none of our other customers which are using this app have as many pictures as the problem-customer... Which is really frustrating, because I can't tell him Hey, you should use less photos in your website (wish I could, though :-p) The only difference between the problem-app and the other apps is that the problem app has: A) a lot more files needing to be copied (number of files and size) B) a lot more (stale) records in the DB Do stale files correspond to the files getting deleted?... If not, this is coming out of left field and you're not telling us enough :-) There are files on the server, which don't have a corresponding record in the DB, and there are records in the DB, which don't have a corresponding file on the server. However, after manually synchronising the 2 (files and records), the problem still occurs, so that isn't it :-( Another strange thing is, that when I try to view the source code of the blank page, my browser asks me if I want to send the request again :-( Check the expiration headers -- If the browser thinks it's out of date, then it will reload to View Source, in some browsers. Also, if the script terminated and Apache sent a non-200 return code, then the browser knows it never got the real page, and may be trying to help you by getting the true page when you do View Source I think switching browsers may actually help this somewhat, as they behave differently in these boundary conditions. I took your advice and installed the firefox plug-in. Only header-info I got from my blank page is Status: ok - 200, nothing else (maybe I should mention again, that at this moment, the script is still running...). In the rare cases that the publish procedure does return the correct result-page, the headers look quite different (i.e. a lot more information than just the status) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Browser displays blank page, while request still being handled
I don't think it's a timeout issue on the server-side, because I've already tried setting MAX_EXECUTION_TIME and MAX_INPUT_TIME to extremly high values, and got the same result (i.e. the blank page). By setting them to extremly low values I was able to verify the app/script/server 's behaviour when it did timeout, and that produced the expected warning-message for MAX_EXECUTION_TIME exceeded. It probably isn't timeout on the server-side. But your BROWSER has a hard-coded limit on how long it's willing to wait for a slow server. You cannot do anything about it. If your script is taking THAT long to run, you have to do some operations asynchronously -- which is just as well, as no user wants to sit there with their browser open waiting for stuff to happen. Copy has to wait until it's finished before telling you the results. If it's copying a 20M file, that takes a while.. If you're copying multiple 20M files, then hey.. there's you're problem. How many and how big are the files in this case? We're talking about multiple copy operations. The first one copies 230 files (approx. 40mb) and the second one copies about 2200 files (195mb). Most files are under 400kb a piece. The request shouldn't generate any output untill it is completely finished. In between different operations, all message are stored in a string-variable. At the end of the publish-request, another request (show_result) is called, and the result-string is placed into $_REQUEST, like this: $_REQUEST[result] = $result; Take my previous paragraphs above and make them much more assertive and remove all traces of doubt. :-) Your script is taking WAY too long for a web-environment. Don't do that. :-) You might be better off running a script to run through cron every 5 minutes or so and doing it all for you.. then getting it to email you the results. Running the script through cron wouldn't be a good idea. The app we're talking about is a kind of Content Management System for photographers, so the publish-request should only be called when the user has finished his modifications to the site and is ready to publish them to his website. You're going to have to adjust your thinking... The user should be allowed to stack up the things they want done, and GO AWAY and do something useful while you muck with all those files. Later, much later, at the user's convenience, they should be able to view what got done, and make a go / no-go decision on publishing -- or possibly just be notified that their decision from earlier has finally been implemented. Because there ain't no way a professional photographer wants to sit there glued to the screen while you muck about with thousands of files. They've got photo shoots to do, calls to make, proofs to review, files to organize, and lives to live. I couldn't agree more. Be he already CAN stack up the things he wants to do. He uploads his pics, reorganizes them a litte, maybe even delete some of them or add captions... whatever he wants. Then, when he is finished and wants his results to go online, he hits the publish button, the old site is deleted, the new files are copied, some XML is generated, et voila... his new website is online in under a minute (even when he has +250mb of files to copy). Only problem is... Right now, he can't see that the publishing is finished, because after 20-40 secs or so (yes, I've been timing this :-s), his browser displays a blank (white) page... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] tired of referencing static variables/constants with 'self ::'
Does anyone know if it's possible to reference class constants or static
variables without having to use 'self::' all the time?
class A {
const MY_CONSTANT = true;
public function test() {
echo self :: MY_CONSTANT; // works
echo MY_CONSTANT; // doesn't work
}
}
I don't think it is possible, but why not? Can zend/php make it work?
Seems it could since this works:
define('MY_CONSTANT', true);
class A {
public function test() {
echo MY_CONSTANT; // works
}
}
It's just annoying my how much boiler-plate I have to write all the time.

[PHP] Re: Browser displays blank page, while request still being handled
General update...
We've finally isolated the real problem (or so we hope :-s) which is
copying the files from dir A to dir B.
After commenting out pieces of code in the script, it became clear that
the blank page only appeared when the copy operations were performed.
That's why I've started testing with a very, very basic script:
?php
if ($dh = opendir(/var/www/web4/html/extdoc/)) {
print(COPY STARTbr /);
while (false !== ($file = readdir($dh))){
if (is_dir(/var/www/web4/html/extdoc/.$file)) continue;
if ($file != . $file != ..) {
if(!copy(/var/www/web4/html/extdoc/.$file,/var/www/web4/html/publish/extdoc/.$file))
{
print(ERROR!!!br /);
}
}
}
closedir($dh);
print(COPY FINISHEDbr /);
}
?
So, what are the results?! Just take a look at this screenshot:
http://www.xi-quadrat.de/rolf/pics/headers.jpg
What are you looking at? Repeated calls to the same piece of php-script.
If you look at the column labeled Content type, you see that there are
2 results: text/html and application/x-unknown-content-type (the ones
that are crossed-out should be ignored). The latter are the ones that
only gave me a blank page as result. The text/html responses are the
correct ones.
In the bottom-right part of the screenshot, you'll see that the header
info received for those incorrect responses was all but complete,
altough it shows a status of OK - 200.
I've also tried using @copy, but this didn't seem to help either. I
still can't figure out why I'm becoming that stupid blank page...
Anywho... I hope this helps other people help me :-s

[PHP] Record ID not being recognized
While I am by no strech of the imagination a ColdFusion expert, I
have built a couple of dozen CF sites over the past 5 years. Am
currently working on my first PHP site and am running into a problem
with the simplest little thing.
An index page is returning a list of active category names. Each name
is a link to a thumbnails page. The photos on the thumbnails page are
links to a display page which displays the enlarged photo and
additional text.
My problem is in getting the thumbnails page to only display the
images associated with the category name selected on the index page.
Either the thumbnail page displays ALL images or it displays none.
Below is the query on the thumbnail page, which is currently
returning no records. If I replace '$recordcatID' with the specific
name of a category, the correct records are returned. Likewise, if I
remove the WHERE statement, all records are returned. So obviously
something is wrong with the sql statement.
But I can't help but feel that I'm missing something in the PHP syntax.
?php require_once('../Connections/connTrail.php'); ?
?php
mysql_select_db($database_connTrail, $connTrail);
$query_GetThumbs = SELECT Photos.Photos_ImagePath,
Photos.Photos_Title, Photos.ID, Photos.Photo_Category,
Photos_Category.Category_Name, Photos_Category.catID FROM Photos,
Photos_Category
WHERE Photos_Category.catID = '$recordcatID' AND
Photos_Category.Category_Name = Photos.Photo_Category;
$GetThumbs = mysql_query($query_GetThumbs, $connTrail) or die
(mysql_error());
$row_GetThumbs = mysql_fetch_assoc($GetThumbs);
$totalRows_GetThumbs = mysql_num_rows($GetThumbs);
?
The link from the index page to the thumbnails page is carrying the
catID number forward, as seen in the resulting URL (thumbs.php?
ID=17), yet the query isn't accepting it.
table Photos_Category contains the category names.
table Photos contains the photos and other relevant information.
Any ideas where I'm going wrong?

Re: [PHP] Convert from jpg to gif ... change dpi...
[EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Actually I don't believe this is exactly right from playing around with Photoshop you can see that you change an image's resolution under Image - Image Size and if you turn off Resample Image, it will retain the same pixel dimensions. GIF's are limited to 72dpi (or ppi if you prefer.. pixel per inch) which matches what is typically displayable or desirable for web content. But when you go to print that webpage, you really see the lack of quality in that GIF image. If you use a JPG and set it for around 300 dpi/ppi, it prints out a LOT nicer. So there's a real easy answer to this question... yes, you can change DPI on the fly when converting JPG - GIF... the downside is that you're converting to 72dpi whether you like it or not because that's the GIF standard. If somebody has more or better information on this, I'd love to hear it but this is how it is as far as I know and have experienced. Well, still a learner on the PHP front but as far as images are concerned, just a bit more knowledgeable. First off, DPI is not a function within an image, it is a function of output and is governed by a combination of the programme doing the output and the device it is being output to. So, to make things clearer, let's take an actual example. We have an image - we'll call it 'image_A' of size (in pixels) of 3000 x 2000. If you want to output that image to a printer (which has a resolution of 300lpi) you will get an image size of 3000/300 x 2000/300 = 10 x 6.67 inches. But the image is still 3000 x 2000 pixels. If you want to output it to a printer with 600lpi resolution then it will print an image size of 3000/600 x 2000/600 = 5 x 3.33 inches and still, the real image size is 3000 x 2000 pixels. However, if we look at it from the viewpoint of the application (rather than the printer), we can see a slightly different perspective on the same data: If we already know that the resolution of the output device (in this case a printer) is 300lpi and we know that we want the printed image to measure 10 x 6.67 inches then we can set the dpi within the application (Photoshop or whatever, that, when it comes to print the image, we want it to tell the printer to print the image at a resolution of 300lpi. If we know that we want to print the image at a size of 5 x 3.33 inches (on that same 300lpi printer) then the application will know that the output resolution to produce that image size *should* be 600lpi. However, the printer is only 300lpi so what takes place is called interpolation where 2 pixels within the application is are output as 1 pixel to the printer. However, monitors typically don't have anywhere near that resolution (typically they are around 72 - 96 dpi) so that same 3000 x 2000 pixel image is now going to a different output device (the monitor) at 96 dpi, so the image size now output on-screen is 3000/96 x 2000/96 = 31.25 x 20.83 inches - which is way bigger than any current monitor (although you could, perhaps, use multiple displays), so, in order for the image to display at a reasonable size on screen, we need to reduce the image SIZE to take account of the SCREEN dpi (96dpi). This means that for the image to display at a size of 300 x 200 pixels on a screen (of resolution 96 dpi) we need to make the image SIZE: 300 x 200 pixels. However, if we want to display the image at a size on screen of, say, 6 inches x 4 inches, then we need to do the calculation for the required image size: (6 x 96) x (4 x 96) = 576 x 384 pixels. The screen resolution likewise is a function of the number of pixels (of the screen) and the size (in inches) of the screen: screen width: 1024 pixels - 13.2 inches; then dpi = 1024/13.2 = 77.5dpi screen width: 1280 pixels - 13.2 inches; then dpi = 1280/13.2 = 96 dpi etc. So, in conclusion, the DPI of an image is an OUTPUT function - it is not inherent to the actual image. However, you may see DPI data stored within the metadata of a file, where it has been stored by the application used to edit it, because the application has stored information you have given it to communicate with (usually) the printer. It serves no other purpose. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

No, and the answer is actually in your example. Copy-and-paste all of
your example code into one file, and just change the second class A to
B so that there isn't a class conflict. Then create an instance of A,
and B, and call both test() methods. You'll get the following result:
111
Why? The reason is SCOPE.
A::test() echos twice, the first for the class constant MY_CONSTANT,
and the second echo's the *global* MY_CONSTANT. Then B::test() echos
the *global* MY_CONSTANT again.
As wonderful as PHP is, it can't read your mind. So if you're looking
for a constant or variable, PHP needs to know where to look. If you
don't specify self::', PHP will look in the global scope, as it did
in your code example. If you want it to look within your classes, you
need to *tell* it so.
And is self:: really a lot of boiler-plate? Really??

Seems it could since this works:
define('MY_CONSTANT', true);

It's just annoying my how much boiler-plate I have to write all the time.

As an OOP programmer, I would expect the scope search to be as follows:

4. GLOBAL: globals
I really hate globals because it defeats my style of encapsulation. If
the search for my constant follows the search I've listed above, self
would never be necessary unless you wanted to pinpoint 3 directly.
Under this same line of thinking, though, '$this-' really shouldn't be
be necessary either unless you wanted to clarify local vs this for
same-named variables.
And is self:: really a lot of boiler-plate? Really??
YES.
$x = ($y == self :: MY_CONSTANT || $y == self :: MY_CONSTANT2);
vs
$x = ($y == MY_CONSTANT || $y == MY_CONSTANT2);
My philosophy is that the more code which is written, the greater the
probability of bugs. Writing less code means less to read and less to
read means easier to comprehend.
From what I can tell, PHP only uses 1) LOCAL and 4) GLOBAL scope unless
you specifically use $this or self, but I just don't think those should
be necessary. Other than that's just the way it is, why IS it
necessary to use $this and self?

[PHP] throttle output streamed from a file?

Sometimes, you can hit the memory limit in PHP before the file contents are completely output resulting in 2M or 8M truncation of output. I have seen code posted to the readfile user comments which hints at trying a userspace 'readfile_chunked' function to break the file into smaller parts, but this is still not entirely what I want: http://us2.php.net/manual/en/function.readfile.php My specific case is this. I have a queue of very large files that I'd like to output in series. I want to do something equivalent to this: readfile($big_file1); // 20 MB readfile($big_file2); // 20 MB readfile($big_file3); // 20 MB readfile($big_file4); // 20 MB but I really don't want to start writing $big_file2 until $big_file1 has been written and I don't want PHP to consume 20 MB at a time either. Ideally I'd like to have an output buffer size of NN bytes and only let PHP fill that buffer until the client has read enough of the bytes to warrant another refill. That way, I might only consume about 1MB sliding window of output. To do this, I would think I need a function in PHP which will output a buffered stream with blocking enabled.

readfile works by reading in the whole file at once - if you don't want

No need to worry about that problem. The data I am streaming will be properly consumed by the client ;-) using something like exec() to call the systems tar gzip commands on the files in question and then dumping out the resulting 'tarball' in chunks as described above would be a way to achieve this. Chunking the output is not the problem either. I know how to fread(...) and fseek(...). I can 'chunk-split' the output into smaller bytes, but that's also not the problem. The problem is that if the printing of bytes does not block during output, then the server (Apache/PHP) will shove as much data as it can into the output buffer as fast as PHP will execute. If the client is only downloading at a slow rate, then we'll end up with a backlog of bytes written by PHP but not yet consumed by the client. Assuming we have a file as large as 10 Gigabytes, that can't all fit into RAM, so where does the data go? but I really don't want to start writing $big_file2 until $big_file1 has been written and I don't want PHP to consume 20 MB at a time either.

I think I understand quite a bit of the streams stuff, but I'm trying to figure out how to control the output buffering and how to dump a large number of bytes (absolutely huge!) to a client who may be very slow.

Will 'echo' block until the client has consumed the whole $size amount
of data? If not, how fast will your while loop execute? If
file_size($big_file1) exceeds 1 TB, does your server end up sucking up
all available memory? Or does PHP crash after hitting a memory limit?

I can't be 100% certain, but I'm pretty sure the buffering from client and Apache and PHP for a simple fopen/fead;echo loop is going to resolve your problems, and take care of blocking. You're basically confusing blocking which all the streams do by default unless you turn it OFF on purpose, with RAM limitation of trying to suck in a 2G file They're not the same problem at all. So, the short answer is: Yes, almost-for-sure, echo will block enough that your won't run out of RAM. You can control the chunk-size in your fread call, basically, to get whatever RAM/performance ratio you like.

The correct solution is NOT to turn register_globals back on !!!
Use something like this at the top of your script:

$_CLEAN['recordcatID'] = (int) $_GET['recordcatID'];
?
.

Then do:
$query_GetThumbs = ... = $_CLEAN[recordcatID] ...;

I took your advice and installed the firefox plug-in.

In the rare cases that the publish procedure does return the correct result-page, the headers look quite different (i.e. a lot more information than just the status) So, here is what happens. #1. Browser asks for URL #2. PHP starts spitting out *SOME* content (maybe even just a blank line) #3. Browser gets Status: ok - 200 #4. PHP script is really really really slow #5. Browser gets tired of waiting for more output, and gives up on PHP #6. PHP keeps going and going and going and... There is no mystery, here, really. It's a bit odd that no other headers come out, but it's possible, depending on the code... Your application is still not designed for a web environment when large numbers of images are involved, really. You're gonna have to bite the bullet (as suggested before) and make the dog-slow image-processing bits be asynchronous with the page generation, by having: the script queues up the stuff to be done, and the script spits out a super-fast page saying We'll have your photos ready shortly -- You will be notified when they are ready some kind of cron job works on the queue regularly when the queue for client X is empty, or a whole batch is done, or whatever, they get an email, and can do whatever needs doing next in human time. By the time you do all that, the whole problem will go away. You could even do it ONLY when the number * size of the files exceeds X if you want.

that is such an oversimplication is almost laughable -
comprenhesibility is
not at all directly bound to the number of characters used to write

My ability to identify specific tokens is blurred by the introduction of
more tokens which amount to nothing more than boiler-plate.
if you have ever read up on how reading/comprehension works

single 'token'
once the brain is acustomed to recognizing it.

I already TOLD you it was static and heaven forbid that I change my mind

$this-y();

Yes, almost-for-sure, echo will block enough that your won't run out

I have written some test code, and yes it appears that the 'print'
statement WILL block if the output buffer is already filled. See this
sample code below:
?php
define('BUFFER_SIZE', 1);
//--
function client_reader() {
// connect back to ourself
$myurl =
http://.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'].?server=1;

$count = 0;
while (true) {
print #;
error_log(read start #.$count++);
$buffer = fread($reader, BUFFER_SIZE);
sleep(2);
}
// all done
fclose($reader);
}
//--
function server_writer() {
// build a buffer to write
$buffer = str_repeat(#, BUFFER_SIZE);
// write our buffer over and over as fast as our client will let us
$count = 0;
while (true) {
error_log(write start #.$count++);
print $buffer;
}
}
//--
if (isset($_GET[server])) {
server_writer();
}
else {
client_reader();
}
//--
?
If you load this, the client code connect back to itself and as you can
see, the writer writes as fast as it is allowed, but the reader will
sleep between reads to ensure that the server writer is much faster than
the client reader.

Ok, so, from the looks of it, the server writer seems to block on print
when 2MB have filled the output buffer. 2MB is a good number, so I
guess I don't need to do anything and everything magically works the way
I would expect.
But ... if I wanted to set the output buffer smaller than 2M, like say
just 1M or 512K, how would I go about that? Is there a runtime
ini_set() value?

Re: [PHP] throttle output streamed from a file?

But ... if I wanted to set the output buffer smaller than 2M, like say just 1M or 512K, how would I go about that? Is there a runtime ini_set() value? You'd have to read the latest php.ini to rule it out, but I don't think it's an ini_set() value. You *COULD* sort of hack it with some sleep() calls on the server and some rule-of-thumb measuring of some real-world clients... At that point, though, targetting it as buffer size is really a mis-nomer and it's really more of a poor man's renice If any of this is running from CLI, you may want to read man nice -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Under this same line of thinking, though, '$this-' really shouldn't

same-named variables.
Languages that let you get away without specifying $this- and self::
do exist...
But, in my experience, after a certain level of complexity is
achieved, you end up getting very confused very fast about where $foo
is coming from...
And it turns into a real nightmare when you inherit somebody else's code:
100,000 lines of code here
echo $foo;
100,000 lines of code here
You really have no idea where $foo came from, do you? :-)
So I personally PREFER that one has to make it clear where the
variables are coming from.
Yeah, I guess I kinda agree with you about that. '$this-' and 'self
::' are nice so that a programmer 'reader' doesn't have to trace scope,
but it's more work on the programmer 'writer'. In most cases, the
programmer writer SHOULD go the extra step because the writer can write
the code easier than the reader can read and figure out the code. So,
in that regard it is nice to 'require' the notation.
I never use 'define()' in my code, however, because I think it's as
dirty as 'global' and globals are bad in my world. So, as a style rule,
I usually only use all uppercase variable names when defining static or
constant properties of an object:
public static $MY_STATIC = array();
const MY_CONST = true;
and therefore, in my code, if you ever find an all uppercase variable,
it's probably scoped to the class. Hence, dropping 'self ::' as a
requirement when I reference class-level constants is not a scary idea
for me.
The other argument is that by defining the language to FORCE '$this-'
and 'self ::', we do just that, we FORCE the use. Not everyone has a
problem with reading code and tracing scope. Programmers should WANT to
write code which is clear and easy to understand, but that style
shouldn't be forced upon them, especially when the language CAN do
without it.
Seems this topic could become a religious debate. But, unlike curly up
'funcname() {' or curly down 'funcname()\n{' debates, there is not
choice a currently. I'm sure there are fans of it both ways, can't we
offer it both ways?

You might do:
define('MY_CONSTANT', true);

Then you can sort of have the best of both worlds...
Though in a hack sort of way. :-^
Hehe, nice. No thanks ;-) Keep yer stinkin' 'define()' away from me ;-)
#2.
If it's that boiler-plate, maybe your class design is flawed...
I mean, the whole point of all this OOP stuff is re-factoring out the
commonalities of code to get a high level of code re-use. If you're
writing something so boiler-plate that it drives you crazy,
maybe you need to step back and look at the whole thing sideways and
see if your obvious class hierarchy isn't really the best hierarchy
to have chosen.
I'm using a 'singleton' pattern and this annoys me:
class A {
private static $MY1, $MY2, $MY3, $MY4, $MY5;
public function __construct() {
if (!self :: $MY1) {
self :: $MY1 = self :: init_thing1();
self :: $MY2 = self :: init_thing2();
self :: $MY3 = self :: init_thing3();
self :: $MY4 = self :: init_thing4();
self :: $MY5 = self :: init_thing5();
}
}
...
}
Why couldn't I have just written:
class A {
private static $MY1, $MY2, $MY3, $MY4, $MY5;
public function __construct() {
if (!$MY1) {
$MY1 = init_thing1();
$MY2 = init_thing2();
$MY3 = init_thing3();
$MY4 = init_thing4();
$MY5 = init_thing5();
}
}
...
}
I mean, I was forced to write 'self ::' like 11 times in that
constructor. THAT is annoying.
I realize I am probably just venting since it's unlikely I can get
anything changed/done on this list. I'm just hoping some internals
developer might see my rants and think it might be something which needs
to be addressed within the language. I can't be alone in my dislikes,
can I?
