problem:
how to make their file SECURED from any hack ? I mean only file owner and web

never user B should be able to access, read or download files of user A.
my guess:
i was thinking to store files outside public_html folder, in the following
way:
/resumes/user A/resume A
/resumes/user A/cover letter A
/resumes/user B/resume B - US
/resumes/user B/resume B - ES
/resumes/user B/cover letter B
Questions:
1. how can i allow user to have access to folder/files outside public_html ?
2. how can i secure that user A has access to his own files ONLY ?
i searched on internet for some help but i did not find anything really
revelent...only theory and no really in details.
I need your help.

You will have to make a few scripts that check whether User A is logged in or
not, read the files with PHP, change the default headers and print the output,
which should be the exact same document. A quick example would be:
?php
// file_exists also checks whether a directory exists
if (!empty($_SESSION['userId'])
file_exists(dirname(__FILE__).'/../resumes/'.$_SESSION['userId']) {
// all the necesary headers, check out the documentation for header()
function on php.net
header('(all the needed headers)');
echo
file_get_contents(dirname(__FILE__).'/../resumes/'.$_SESSION['userId'].'/resume
A.doc');
}
Above is basic pseudo-code, not tested. Now all you have to care about is that
userId is correctly set and that nobody can hijack that user account.

Re: [PHP] mysql custom global defined variable
On Mar 13, 2013, at 10:35 AM, Kevin Peterson wrote:
In my database design, I tend to store some variable that is meant to be
acting as a ROLE or TYPE as SMALLINT. For example :
CREATE TABLE `house` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`type` smallint(11) NOT NULL,
)
And in php, I do
define('HOUSE_SMALL_TYPE', '0');
define('HOUSE_MEDIUM_TYPE', '1');
So in php, in SELECT queries I do :
$this-db-query(SELECT * FROM house
WHERE type=?;, HOUSE_SMALL_TYPE);
My questions are :
1. In the php part, is there is a better way to do this ?
2. In the mysql itself, does mysql also has global define functionality (like
the define in php) ? I also want to do kind of SELECT * FROM house WHERE type
= HOUSE_SMALL_TYPE in mysql query.
Question 1:
I see no possible improvements, you could however use an array with values
instead of constants, but that's rather a personal choice as I don't like
constants that much, unless you are on your own namespace.
My example implementation:
$houseTypes = array(
'house_small_type' = 0,
'house_medium_type' = 1,
etc.
);
Question 2:
You could use ENUM data type, but it has quite a few disadvantages:
1- Translation could be tricky to implement
2- DDL shouldn't be used for data!
3- Updating or deleting values can leave your old records in an inconsistent
state
You can also use SET to set variables, I've never used them but I think they
could work in your case:

In that case, you can always do a wget or cURL request to your server forcing it to clean APC cache through the webserver, I assume that if you're deploying through symlinks you want a really minimal downtime during update, the only bad thing about this method is that you need to protect the script from external visitors through htaccess or similar methods if you're using other webservers. Make the request like: wget http://localhost/apc-clear.php -O /dev/null 21 man wget for more information about how to use always the correct options. If you are using Apache, you can also give a try with a graceful restart, in red hat based systems, you would restart apache with: /etc/init.d/httpd graceful or apachectl graceful I have never tried this on a production machine so I really don't know if that is gonna work, but the idea after this method is to: The USR1 or graceful signal causes the parent process to advise the children to exit after their current request (or to exit immediately if they're not serving anything). http://httpd.apache.org/docs/2.2/stopping.html#graceful Hope this helps ^^ Met vriendelijke groet, Camilo Sperberg W: http://unreal4u.com T: http://twitter.com/unreal4u -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Have anyone already tested PHP inside RAM disk with some Apache/nginx accessing those files or even session files? It's just for curiosity and performance analysis. Thanks. -- -- Att, Alan Hoffmeister I have not tested it but I think it wouldn't be much difference respecting APC for example, maybe a tiny little bit faster reading sessions and other file stuff because RAM have really small access times, but database connections and stuff would still be your main bottleneck (I'm assuming you do). I would install APC and set /tmp up into a RAM disc, mainly because not only do MySQL write temporary files into /tmp (example: if MySQL decides to create a temporary table which would be with almost any grouping you do), also apache does and, if you haven't setted up the session routes, sessions will also write itself to /tmp. Plus, if your machine happens to suddenly reboot, you won't lose any important stuff. Getting /var/log/ into an SSD or RAM disk should help too, but again: if reliability is important to you, I wouldn't do that.

[PHP] Expected behaviour or bug?
Hello list, I have a little question with PHP's internal working. I've managed
to reduce the test to the following lines:
$globalVariable = 'i am a global variable';
function testFunction() {
global $globalVariable;
unset($globalVariable);
}
testFunction();
if(isset($globalVariable)) {
var_dump('global variable IS set');
} else {
var_dump('global variable is NOT set');
}
When executing the above test, you will get printed that the global variable is
set, despite unsetting it in the function. Is it really the intention to unset
a global variable inside a function locally or have I just happen to found a
little bug?

Sometimes, it helps reading the manual...
http://lmgtfy.com/?q=php+unset+global
If a globalized variable is unset() inside of a function, only the local
variable is destroyed. The variable in the calling environment will retain
the same value as before unset() was called.
[...]
To unset() a global variable inside of a function, then use the$GLOBALS
array to do so:

Re: [PHP] Function size
I use a lot of switches but they are always small in size because they look
mostly like this:
switch($action) {
case 'hello':
$someObject-executeAction();
break;
case 'world':
$someOtherObject-executeOtherAction();
break;
default:
$this-anotherAction();
break;
}
Maybe it's not the rule for some really specific small functionality which I
know I won't be using ever again, but that's the latest trend I've acquired in
order to improve readability. Personally I find that the particular switch
statement disorders the code, but at least it is a lot better than a lot of
if/elses xD
Haven't you tried this approach or does that particular function do have a lot
of cases?
Greetings.

You hit upon a theory of mine -- and that is our functions grow in size up
to our ability to view them in their totality. When our functions get
beyond that limit, we tend to refactor and reduce.
When number of lines becomes the criteria of function size? Wouldn't it
depends on the task the function is doing? I follow this rule, *Each time I
end up need a code block I wrote earlier, I convert it to a function. *So
simple. This way you re-factor your code automatically and you dont do any
copy paste. Last year someone on Stackoverflow asked something like
this[1]. And that was my answer.
Hi,
While this could be one reason to start a new function, it should not
(IMO) be the only reason. Sometimes you can have a large complicated
function, with say 200 LOC. While I wouldn't need any of these lines a
second time, I usually try to rip blocks of say 50 lines out and put
it in a seperate function, so that the main function itself is easier
to understand.
- Matijn
I'm of the same mind. Generally I'll split a function if I'm reusing
more than a couple of lines of code. I only split a large function if
it's actually doing several things, if it happens to need 200 lines to
perform one 'step' then I'll leave it as is. While I do prefer my
functions to fit into a single 'screen', it rarely happens quite like
that, because I move from screen to screen with different resolutions,
so there's no constant limit for me.
As a rough example, on a random selection of 27 functions taken from a
controller on a site I worked on I get these general statistics:
Functions: 27
Mean lines: 22.5
Mode lines: 3
Max lines: 218
The function with 218 lines is a large switch, and it doesn't make sense
to do it any other way, because it would actually end up less readable.

Re: [PHP] code deployment through php
On 1 mei 2012, at 10:59, rene7705 wrote:
Hi folks.
I was here a while ago, trying to figure out how to keep deployment
instances of my common code, running on more than 1 site, in sync with
eachother.
I've looked at rsync which was recommended here, but didn't like it much,
nor could I find a good windows version of it.
So yesterday, I decided to try a pure PHP solution. My thinking was: run a
PHP sync script once on each physical machine that holds possibly multiple
copies of my common code, and FTP the common code only 1 time because I use
only 1 shared hosting account besides my windows development machine.
I've gotten it so far that it creates an imo good list of what to copy
where.
The only problem I can foresee is that the copy command will take more than
30 seconds, which makes it hard to run at the shared hoster.
And obviously, it's going to need some good input checking to prevent
abuse.
I've put up a demo at
http://skatescene.biz/sites/mediabeez.ws/sync_secret_cndj593n2/ , you can
execute the code job to see it in action.
I'll also post the working copy of my sync library at the bottom of this
post. The only thing missing is the actual copy($source,$dest), I think.
But, I'm wondering if this is a good approach to code deployment. It
certainly seems easier and more convenient to me than using rsync. Maybe
i'm an amateur indeed ;) Anyways, all criticism is welcome here. Thanks
for your time! :)

Re: [PHP] Randomly unable to read set variable from class
Sorry wasn't able to reproduce it on my test machine.
Do you have any external modules loaded such as APC, memcached, xDebug maybe or
other that can affect the output on that machine?

The output when this happens would be:

I do know the mechanism that is happening. I just can't figure out where the problem is without inserting print statements. Presumably, you are calling this cron job with some process which runs the PHP script through a URL on your webserver. Yes, that is correct. Using curl to launch the script via the web server. 1. Modify the script so that it does actually output something, thereby making the error go away. When the script starts, it prints a banner with the script name and date/time stamp. When it completes, it is supposed to print aggregate results, time spent. I know it's encountering this problem before it reaches the end as not all the data gets processed. I can't tell where it is stopping though. If I put it in debug mode, it prints out a lot of data from the beginning of the script, and never encounters this problem. 2. Run the script directly with PHP instead of via your webserver. E.g.: php -f yourscriptname The way the script is designed, it depends on some $_SERVER values, which wouldn't be set if running directly from the shell.

The PHP Devs have already clarified only the ? version is, not this one. http://www.php.net/manual/en/ini.core.php#ini.short-open-tag I had no idea, I thought short tags also implied short if-else, short echo and so on, good to know that, thanks for the clarification ;) Second question: zend studio displays all variables used by a script by clicking the arrow next to te file name. I've used ZS for 4+ years now, and comicaly have never even used those little down arrows next to a file. HAHAH! Good to know. Although it is a little strange as they seem to only be where you use a = assignment. It doesn't know about - or other instances of that variable (like if you echo it or something). But still could prove useful. Eclipse/Zend Studio is so full of options that you can miss a lot of them. Another downside of the little arrow thing is that it doesn't recognize arrays, which is obvious because arrays can only be read on runtime, well, same thing as objects. If you want to display it in runtime, you can: print_r($GLOBALS); Whoa nelly! That prints out WAAY too much information ;-) But thanks. Not sure why I didn't think of that one. Maybe because at one time I did use it, got sensory overload from the amount of data it spews to the page, and then blocked it out of my mind for future use. :) Yeah I know it displays a lot of information, but I use it sometimes and it's the only way I know to display all variables, arrays and stuff in a neat and nice way. You can also install xDebug and use the included debugger in ZS, but sometimes using a simple print_r is faster.

(Or less, configuration files are usually 400, just read access). If the user is Apache (and Apache is in the same group you are), he will need to read your files, so you should at least have 740 and also he will need execution rights on the directory which will result in 750. If apache isn't in the same group you are (most probably scenario) you will need 755. Strictly speaking, it should be 705.

Please take into account that lighttpd does have some random high cpu-consumption problems, it could be that also. Give nginx a try instead. Also: microtime by itself isn't enough, sum time() to it because if a script lasts more than 1 second you can end up with negative total time, microtime doesn't have a seconds counter, only microseconds.

This seems to be your error. You set $errctx to be a string. But later on
you use it as an array.
Remove the = '' part. And it will function as expected.
You're right... However I don't like leaving non-default value in functions
so I did something like if(empty($errctx)) $errctx = array() in the first
line of the custom error handler which threw out the error message and
everything works ok now.
But -and correct me if I'm wrong- isn't isset (or empty) supposed to return
a FALSE whenever that variable doesn't exist?
With your help, I could reduce the test case into:
$asdf = 'hello world';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This works ok.
$asdf = '';
if (empty($asdf[4]['inventing'])) echo 'nice little world';
if (isset($asdf['inventing'][6])) echo 'little nice world';
// This returns E_NOTICE
Shouldn't these 2 examples work exactly the same way? (AKA as Nº 1). If
not... why not? Both are string types, onyl difference is that one has no
characters in it while the other does, but essentialy they are both the

Why do you put ?php echo...? inside an echo statement in php space?
I think you may have mis-readed the code, I can't find where I put an ?php
echo inside an echo. I do a lot of opening/closing tags which contributes to
messing things up estetically but it works...
Any way, the posted code had a lot of remniscants of the production code,
here is a simplified version which does the same as above but .. well,
simplified :P
?php
date_default_timezone_set('America/Santiago');
ini_set('memory_limit','1M');
ini_set('display_errors',1);
error_reporting(-1);
function my_error_handler($errno = '0', $errstr = '[FATAL] General Error',
$errfile = 'N/A', $errline = 'N/A', $errctx = '') {
global $clean_exit;
if(empty($clean_exit)) { // if isset or !empty, the script would have been
exited cleanly.
ini_set('memory_limit','16M'); // This would be just to have enough
memory to print out the error.
echo 'h5-- BEGIN ERROR --/h5Error Ndeg;:

if (isset($errctx['r']['print'])) echo 'pTHIS LINE GIVES THE ERROR,

echo 'h5-- END ERROR --/h5';
die(); // shutdown_function == manual die() or else it will continue to
execute.
}
}
set_error_handler('my_error_handler');
register_shutdown_function('my_error_handler');
for ($i = 0; $i 15000; $i++) $a[$i] = mt_rand(1,255);
$r['print'] = (string)$a[1]; // Just to asign something to that variable.

[PHP] Regular expressions, filter option1 OR option2
Hello list :)
Just a short question which I know it should be easy, but I'm no expert yet
in regular expressions.
I've got a nice little XML string, which is something like this but can be
changed:
?xml version=1.0 encoding=utf-8?
boolean xmlns=http://tempuri.org/;false/boolean
The boolean value can be true or false, so what I want to do, is filter it.
I've done it this way, but I know it can be improved (just because I love
clean coding and also because I want to master regular expressions xD):
$result = preg_match('/true/',$curl_response);
if ($result == 0) $result = preg_match('/false/',$curl_response);
I've also tried something like:
$result = preg_replace('/^(true)|^(false)/','',$curl_response); // if not
true OR not false = replace with empty
and also '/^true|^false/' which doesn't seem to work.
Any ideas to filter this kind of string in just one expression?
Thanks in advance :)

As far as I can tell, are you just trying to grab the content from the
boolean tag text node? If it's limited to this basic example, there's
likely not much of a need to use dedicated DOM functions, but consider using
them if you need to work on more complex documents.
If you are just trying to determine if the value is indeed true or false
and nothing else, then a regex could be overkill here. As you only need to
check two values, consider:
if(strpos($xml, 'true') || strpos($xml, 'false'))
{
// text node content is OK
}
else
{
// bad, bad input, go sit in the corner
}
Indeed Ashley, I'm trying to get the TRUE / FALSE value from the boolean
tag.
After reading again, you're absolutely right: strpos does just what I need
it to do: a simple search for a true or false. (Or null, in which case
strpos will be FALSE anyway).
Thanks for your suggestion, I was doing an overkill here.
@Shreyas: thanks for the link! It is very helpful to speed up the testing a
bit!

inheritance of this kind is useful if you have common descendants for

Nice thought. I imagine something like a DB wrapper, and implementing things
such as multiqueries and others on an extension based on the basic
connection made in the original class. Am I right on that?
another use, is a modification of a certain component.
descend it from the parent object and override the functions.
you can do pre processing and post processing by overriding functions.
So, you're saying I can do something like this? :
class foo {
function hello($a = '') {
echo 'hello '.$a;
}
}
class bar extends foo {
function hello($a = '') {
if (!empty($a)) parent::hello($a);
else echo 'bye world';
}
}
$xx = new bar();
$xx-hello('asdf');
$xx-hello();
Which will print (hopefully, haven't test it yet):
hello asdf
bye world
That would be really a nice way of updating certain vital apps, without
breaking basic functionality.
Thanks for your answer :)

[PHP] In what scenario an extension of a class is useful?
Hello everybody :)
I'm really intrigued on something... In what real-world applications could
an extension of a class be really useful?
Let's say I have this code:
class foo {
function hello_world($a) {
echo 'foo hello world';
}
function bye_world() {
echo 'foo bye world';
}
}
class bar extends foo {
function hello_world($a,$b) {
echo 'bar hello world';
}
}
Point 1: Why not just overwrite the hello_world method in the foo class in
the first place? Wouldn't that save code and possible incompatibility or
consistency issues between the code you've already written and between the
two classes ? (Assuming that you do some things based on the $a and $b
values).
Point 2: On the other hand, maybe I could apply different operations to both
(e.g.: return 1 in foo and 2 in bar), without breaking the basic
functionality already achieved in the foo class. (Maybe considering that I
want to apply an update or patch to an already existing application,
however, is this is the scenario, I should always fix the old code wherever
I invoke the foo class which returns us to point 1).
Point 3: Ok, maybe I don't want a specific class to be so huge and I
separate it into pieces of classes. But then again, wouldn't it be simpler
to just save some code and keeping only one file with the entire class?
Is it just that or do I miss something else? I'm not saying it is useless,
it sounds indeed fantastic to work with... but I just can't imagine in what
real-world cases this would be useful.
Greetings !

Re: [PHP] strip out repeated ocurrence of a string
a certain string can contain the following information:
$string =
'hi{value1;value2}bye{value1;value3}hi{value1;value4}hi{value1;value2}bye{value1;value2}';
What I want is to be able to get this result:
$string =
'hi{value1;value2}bye{value1;value3}hi{value1;value4}bye{value1;value2}';
(the order of appearance doesn't matter)
Assuming the duplicate segments are identical.
I'd use explode() and convert the string to an array. Use } for the
delimiter.
Then use array_unique()
And then use implode() to restore the string.
Really nice solution indeed :D I didn't know array_unique() (well, that's
not entirely true, I had read about it once or twice, but didn't remembered
it).
Anyway, I remembered after I sended the mail that the order DO matter, but
that is just reversing an array :)
Just for the record, the applied code is:
$string =
implode('}',array_reverse(array_unique(array_reverse(explode('}',$string);
First, an explode of the string to create an array, than I reverse it so
that the last ocurrence of the repeated part will always be last, after that
I apply array_unique, de-reverse it and implode it all back together as a
string.
Result?
input:
hi{value1;value2}bye{value1;value3}hi{value1;value4}hi{value1;value2}bye{value1;value2}
output:
bye{value1;value3}hi{value1;value4}hi{value1;value2}bye{value1;value2}
Thank you very much !
@Ashley: It must be done in PHP, because it should run in any environment.
But thanks anyway, any help is apreciated: you just saw that there was a
much easier way than trying to use regular expressions or str_replace when
using arrays is considerably faster (especially because the $string won't be
a few bytes, it could range from ~5 bytes up to ~300+ KiB).

Re: [PHP] 304 Not Modified header not working within a class
Problem solved!!!
Everything was working ok with PHP. My class was working ok. The engineering
and logic behind PHP was working. So... what was the problem? Apache...
well, it wasn't a problem, but a misconfiguration or better said, a
mis-optimization.
In my first message, I stated: (quote)
there is no way I can send a 304 Not Modified header, when the data is
*over* ~100 bytes.
After 8 hours of working with this problem (which included sniffering and a
lot of workarounds), and while I was smoking my final cigarrette before
going to bed, I remembered that some time ago (well, some time like 2 years
ago xD), I had enabled mod_disk_cache, with the following configuration:
IfModule mod_disk_cache.c
CacheRoot /tmp/apachecache/
CacheEnable disk /
CacheDirLength 1
CacheDirLevels 5
CacheMaxFileSize 128000
*CacheMinFileSize 100*
/IfModule
I commented that part, restarted Apache and bingo Instantly I had an 304
header.
What do I think the problem was? Whenever Apache received a request, it
handled it directly from _his_ cache and simply omitted what PHP was telling
him to do. The weird thing was that the class entered the 304 header part,
but Apache always ended up sending an 200 OK header and then the CSS. In
first place it shouldn't have sended the CSS because when I entered the 304
part, it should have died. It simply couldn't send any other output. (And
that was why I sniffered, if it shouldn't send the CSS; he must have been
send some kind of error, but my surprise was really big when I saw that the
raw data was just plain CSS, no other data was present).
Why was Apache then sending a 304 whenever the data was under the 100 byte
limit? Because he didn't have it in his cache and was obeying what PHP told
him to do. (This configuration created a cache whenever the file size is
between the 100 and 128000 bytes).
Anyway... now I will be publishing the class soon on phpclasses.org under
the BSD license. I'll work now on documentation and code cleanup but
whenever it is ready I will leave the link in this same list (if it is
allowed) xD
Greetings, a lot of thanks to Richard for his code and Rene for his
suggestion to take a look at Apache and good night :P (Despite being 7AM xD)

Now that I think about it... yes; but I send the last modified header anyway
the first time (when $_SERVER['HTTP_IF_MODIFIED_SINCE'] == null):
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).' GMT');
So if it isn't exactly equal, then the browser cache simply doesn't have the
latest version. It is impossible anyway that the browser can have a newer
version that doesn't previously exist on the server.
My best guess is that it doesn't affect the process: when I implement that
code in my class, it enters that part (meaning all the comparisons are ok)
but afterwards it keeps sending an 200 OK header when I explicitly tell
Apache to send the 304 Not Modified one.

What is funnier is that it enters the 304 function within the class, but
apparently it doesn't respect that and ends sending a 200 OK header anyway.
Let's take a look at the code:
This is a simple test scenario implemented within a little file just to
proof and make sure it is working before I adapt the code in the class.
Everything is ok here:
define('TIME_BROWSER_CACHE','3600');
$last_modified = filemtime('blabla.css');
if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) AND
strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == $last_modified) {
header($_SERVER['SERVER_PROTOCOL'].' 304 Not Modified',TRUE,304);
header('Pragma: public');
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).' GMT');
header('Cache-Control: max-age='.TIME_BROWSER_CACHE.', must-revalidate,
public');
header('Expires: '.gmdate('D, d M Y H:i:s',time() + TIME_BROWSER_CACHE).'
GMT');
die();
}
header('Content-type: text/css; charset=UTF-8');
header('Pragma: public');
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).' GMT');
header('Cache-Control: max-age='.TIME_BROWSER_CACHE.', must-revalidate,
public');
header('Expires: '.gmdate('D, d M Y H:i:s',time() + TIME_BROWSER_CACHE).'
GMT');
Now the class (simplified):
public function printme($method = 'file') {
if($this-qCSS 0 AND ($method == 'file' OR $method = 'inline')) {
if ($method == 'file') {
$last_modified = filemtime(CACHE_LOCATION);
if (isset($_SERVER['HTTP_IF_MODIFIED_SINCE']) AND
strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == $last_modified AND
$this-valid_cache()) {
// $this-valid_cache() determines if the internal CSS cache is
still valid. If it is, it returns TRUE, else FALSE
header($_SERVER['SERVER_PROTOCOL'].' 304 Not Modified', TRUE,
304);
// also tried sending header('HTTP/1.1 304 Not Modified'); but
that didn't do the trick
header('Pragma: public'); // Useless? Maybe, but the function
works with or without it.
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).'
GMT'); // Always good to send this too.
header('Cache-Control: max-age='.TIME_BROWSER_CACHE); // idem
header('Expires: '.gmdate('D, d M Y H:i:s',time() +
TIME_BROWSER_CACHE).' GMT'); // idem
$fp = fopen('cache/hi.txt','a'); // Just to check stuff
fwrite($fp,'header 304 sended, let\'s die'.\n); // It logs this
without problem, which means it really enters this function when needed.
fclose($fp);
die(); // Terminate script execution or else it would continue to
the bottom, which isn't necessary.
}
header('Content-type: text/css; charset='.CHARSET); // From here on,
it applies only if we need to send the CSS.
if (USE_BROWSER_CACHE) { // Constant [TRUE|FALSE] which defines
whether to use the browser cache or not.
header('Pragma: public');
header('Last-Modified: '.gmdate('D, d M Y H:i:s',$last_modified).'
GMT');
header('Cache-Control: max-age='.TIME_BROWSER_CACHE);
header('Expires: '.gmdate('D, d M Y H:i:s',time() +
TIME_BROWSER_CACHE).' GMT');
}
// Rest of the function: get the CSS and echo it, within an
ob_start('ob_gzhandler');
()
$content_length = filesize(CACHE_LOCATION);
if (extension_loaded('zlib')) $content_length = ob_get_length();
header('Content-Length: '.$content_length); // Necesary if we don't
want to send the CSS in chunks.
if (extension_loaded('zlib')) ob_end_flush();
Other useful information:
- Code #1 returns an 304 when it is needed, even when the CSS size is over
50kb. (Haven't test any CSS over that size yet)
- Code #2 goes into the 304 part but doesn't send the 304, unless the total
CSS size is under 100 bytes.
- Tried also with ETags, didn't worked either.
- Tried increasing or decreasing TIME_BROWSER_CACHE, didn't worked.
- Tried with/without Pragma header, Last-Modified header, Cache-Control
header, Expires header, all the 16 posibilities. None of them worked.
- Tried with getallheaders() and making the proper changes.
- Tried with/without ob_gzhandler.
- Tried with/without ob_start().
- Tried with all options on/off within Last-Modified header and
Cache-Control header (must-revalidate, public, etc). None of them worked.
- Tried searching on Google, reading the comments on php.net and searching
within this list. Nothing like this came up.
