[PHP] ob_start(ob_gzhandler) producing garbage before document header
Hi, using ob_gzhandler produces a 5-8 characters, �“×2���, before the document header. Using ob_start() does not produce the text garbage. Is there a way to get ob_start(ob_gzhandler) to behave? Many thanks in advance Abridged Code: ob_start(ob_gzhandler); //produces initial text garbage # ob_start() //Produces No initial text garbage # Cache the output $data = ob_get_contents(); //ob_end_clean(); Can't seem to make this work with ob_gzhandler # Remove any whitespace that screws up the headers (cannot modify headers error) print trim($data); # Flush in all ways known to man flush(); ob_flush(); ob_end_flush(); -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] ob_start: Capturing STDOUT and STDERR
Hey There,
I looked at the ob_start manual and found a segment of code that can be used
to capture the output of a shell script and place it into a log file. One
of the entries indicates this should work for both STDOUT and STDERR
(29-Mar-2007). I wrote the following piece of code to test it out.
function logger($buffer)
{
$handle = fopen('/var/log/test.log', 'a');
fwrite($handle, $buffer);
fclose($handle);
}
ob_start(logger);
This will capture the output buffer until the shell terminates when the
buffer is dumped to the test.log file. This is a simple mechanism and it
works really well to keep STDOUT from going to the console and logging it.
Unfortunately, STDERR continues to go to the console which is what I am
working to avoid.
I would like to capture STDOUT and STDERR using this technique. I am working
to create a self contained script that does not rely on some external script
to capture the output. The actual application needs to perform some
post-processing of the output buffer at the end of the script.
Any pointers in the correct direction would be helpful! Thanks, Greg

You could use set_error_handler() and make your own function to echo
out the error.

[PHP] ob_start eval?
I have a template system that takes some data, scrubs it and then with a load method includes the required template. I need to add a param so it doesn't simply include but returns the contents of the template in a string with all of the vars populated. I tried: ob_start(); include my template $template=ob_get_contents(); ob_clean(); return $template; But this returns the template it's it's raw for with all of tha ?=$whatever? tags. Can I fill these in and still pass as another var without using eval()? What do other template systems to do return a template as a string on load? Thanks!
Re: [PHP] ob_start eval?

Re: [PHP] ob_start(ob_gzhandler) and error handling functions
Hi again,
Just wandering if someone could help me on this one- I'm quite anxious
to get something together. As I said in the last email I just want to
use ob_start(ob_gzhandler) but it doesn't seem to work with the error
function. I think it might be something to do with not being allowed
within a 'callback function'- well that's what it says on the php
manual. The thing is I'm not sure what that means, I find that section
not particularly clear. Please can someone help!

Can you show us where/how you checked ob_get_level()?
Cuz I don't really understand what the OOP stuff should do for a
callback, and would have to re-read the docs, but my first guess is
you do the ob_get_level() after the buffer is all done and the
callback is finished and gone, so the level is back to 0...
To give an small example see below.
The first file is the class file.
Lets pretend the 'MyFunctions' class is included already.
In index1 the ob_get_level() get the wrong count.
In index2 however the ob_get_level() get the right count.
Example:
--
File: class.MyFunctions.php
--
?php
class MyFunctions {
public static function myObCallback($buffer) {
return 'Samplebr'.$buffer.'brSample';
}
//Several other functions etc.. etc..
}
?
File: index1.php
--
?php
ob_start();
//ob_get_level == 1 - This is correct.
ob_start(array('MyFunctions', 'myObCallback'));
//ob_get_level == 1 - This should be 2.
?
File: index2.php
--
?php
function myObCallback2($buffer) {
return 'Sample2br'.$buffer.'brSample2';
//Or this. Works also.
//return MyFunctions::myObCallback($buffer);
}
ob_start();
//ob_get_level == 1 - This is correct.
ob_start('myObCallback2');
//ob_get_level == 2 - This is correct as it should be.

Re: [PHP] ob_start session_start
Sure, ob_start begins a buffer allowing you to display content in the browser before your script has finished executing. This is useful when loading a time intensive page to tell the user to wait. When you create a session (provide php is not configured otherwise) php attempts to store a cookie with the session id that corisponds to the session file on the server. If it cannot set this cookie it appends the session id to pages in the get format. If you were to call session_start() after the output buffering, content and consequentially the headers would have been already sent to the browser. Since cookies must be set in the headers and the headers must be set before any content is sent to the page, to use cookie based sessions you must begin the session before the buffer.

Since, well, any code that exist is potentially going to rely on a session state. If you are trying to use ob_start() to rid of the common error 'headers already sent in some_file.php on line such and such', i would first consider why that is causing the error and how can you call session_start() before that happens. Since '97 i think i've used ob_start twice, in all my php apps, and that was cause I wanted to filter the output either with tidy or modify the data in a very obscure way.

Re: [PHP] ob_start session_start
Zack Bloom wrote:

Calling ob_start() turns on PHP's output buffering. In other words, it
buffers output from the moment this function is called until the buffer
is flushed (whether explicitly or because the script finishes).
As long as PHP is buffering the output, the client can't get it.
This is useful when loading a time intensive page to tell the user
to wait.
I think you might be thinking of flush(), which flushes PHP's output
buffer as well as the output buffer of the web server (or whatever
backend PHP is using).
When you create a session (provide php is not configured otherwise)
php attempts to store a cookie with the session id that corisponds
to the session file on the server. If it cannot set this cookie it
appends the session id to pages in the get format.
Yeah, PHP includes a Set-Cookie header in its response. If
session.use_trans_sid is enabled, it will also rewrite URLs to include
the session identifier. When PHP receives a request that includes a
session identifier, it knows whether the client accepts cookies.
if (session identifier in cookie)
{
cookies enabled
}
elseif (session identifier in URL)
{
cookies disabled
}
else
{
new user
}
If you were to call session_start() after the output buffering,
content and consequentially the headers would have been already
sent to the browser.
Maybe you're getting the buffering and flushing concepts reversed? Think
of a toilet - buffering is the handle up, and flushing is the handle
down. :-)
Hope that helps!
Chris

Re: [PHP] ob_start changed from php4 to php5?
Hello! I'm also guessing that it's the LAST line of the file with the encodeDomain function in it that you include in your test.php I'm also guessing that there's a NEWLINE character after the final ? in that file on your 5.0.4 box, but that NEWLINE character is *NOT* there on your 4.0 box. No, there are no newlines at the end of any files. The problem was a new behavior of system() in PHP5: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. Obviously system() in PHP5 tries to flush, but because it's wrapped in ob_start() end ob_end_clean(), it's doesn't actually do. Unfortunately an interal flag in PHP is set to output has been sent anyway (bug?). I first changed it to passthru() instead of system(), but maybe I should use shell_exec() in the future.

I'm also guessing that there's a NEWLINE character after the final ?
in that file on your 5.0.4 box, but that NEWLINE character is *NOT*
there on your 4.0 box.
The redirect works if I don't use the encodeDomain() function. Does
the

Does maybe PHP simply say output has been send although it hasn't
been
send actually?
Sort of.
Apache may be buffering output, or you may even have output_buffering
set to on in php.ini or gzip may be involved and buffering or...
But as far as PHP is concerned, the headers went out even if
somebody else somewhere is buffering them and you don't see any
output.

[PHP] ob_start changed from php4 to php5?
Hello,
I have a function catching the output of a script:
function encodeDomain ($domain) {
ob_start();
system(echo '$domain');
$output = ob_get_contents();
ob_end_clean();
}
And I have a php-script using this function:
?
encodeDomain($domain);
header(Location: http://www.php.net;);
?
While this worked fine in PHP4, with PHP5.0.4 I always get the following
error:
Warning: Cannot modify header information - headers already sent in
test.php on line 4
The redirect works if I don't use the encodeDomain() function. Does the
system-output affect the php-outout status in any way? I checked the raw
http-output and I can see nothing of the output from the system()-call.
Does maybe PHP simply say output has been send although it hasn't been

Re: [PHP] ob_start changed from php4 to php5?
This doesn't help with your ob problem, but if you simply want to
capture the output of the system cmd, then you can use $output =
shell_exec($command) instead of system() IIRC.

Can someone help me with preg_replace?

It converts it to:
John Doe, a href='employee.html?id=456890123'456890123/a, is a new

[PHP] ob_start() and session_start() conflicts
Hi, I am currently working on a download script, where I use a session variable to make sure that the downloaded file cannot be linked directly. However, this protection is not mandatory, so that a download can also be created, which can be initiated via a direct link. So, I'm using the following for the file download: ob_start(); $filename = $sql_result[0]; $type = $sql_result[1]; $path = $sql_result[2]; header(Content-Type: $type); header(Content-Disposition: attachment; filename=$filename); readfile($path); ob_end_flush(); ...which is working just fine as a standalone, but as soon as I add session_start(); before the ob_start() call, then the download is no longer working properly. The following happens in such a case: if the browser window was used to click through the script and initiate the download, then the file can be downloaded properly. if a new browser window gets opened and you try to access the file download via a direct link, then you get the filename presented for download without type and path info, e.g.: Filename: index.php?cmd=downloadid=12 Type: Path: As soon as I comment the session_start(); it's working just fine, though and the file can be downloaded properly via direct access. Am I right to assume, that since the session_start(); is sending headers as well, the ob_start cannot work properly anymore? And since it only happens when you're opening a new window and try to access it directly, I assume it's related to the fact, that the session gets set at the user end with a cookie and therefor causes the problem? Would preventing session cookies and using trans_id maybe help here? Thanks, Duncan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] ob_start and transparent sessions 4.3.2
Hi, I've got a strange problem with enabled transparent sessions for my scripts. Before upgrading to PHP 4.3.2 I could use output buffering (ob_start()) and sessions without problems. Meanwhile with this new version the PHPSESSID is NOT appended to any link like html - tag (a href or something like that). I found a solution by writing my own session-handling and using regular expressions to append the session-id to any link, after outputting the content of the buffer, but this is not a really good solution, I think. (Btw. session.use_trans_id is on ;)) Has someone found a solution or has had an equal problem with 4.3.2? Thanks.

RE: [PHP] ob_start and transparent sessions 4.3.2
Hi, I too am running PHP4.3.2 and never took any notice about the session id's being appended and stuff .. after reading your message I got a little alarmed, since I'm also using output buffering. So, I turned off my cookies, restarted my browser and saw that indeed no session id's were appended. Now, when I checked php.ini, the value appeared to be '0'. That was quite an explanation. I changed it to '1' and it all worked. Maybe this makes your problem a little weirder.. But the problem is not on the PHP version. You might want to check if session.use_trans_sid is really set to 'On'. If it is, try changing it to '1', restart apache and see if it works now. Also, check if your cookies are turned off, since with them turned on, there's no need for php to add the session ID and thus it won't happen.

Re: [PHP] ob_start -- output buffer problem
because the flush happens after everything is done, including the fputs
thingy.
you have to call ob_get_contents() or something like that.
I always to this
ob_start();
do something
$data = ob_get_contents();
ob_end_clean();
then I work with the $data later.
but if you don't use the ob_get_contents(); or ob_end_clean(); then PHP
waits until everything is done, and then flushes.

Hi all,
to quote from http://www.php.net/manual/en/function.ob-start.php
void ob_start ( [string output_callback])
An optional output_callback function may be specified. This function
takes a string as a parameter and should return a string. The function
will be called when ob_end_flush() is called, or when the output
buffer is flushed to the browser at the end of the request.
My callback function does not get called unless I manually call
ob_end_flush().
I'm not interested in calling ob_end_flush() at all, I want my callback
function to be called when the output buffer is flushed to the browser
at the end of the request so the question is why isn't this happening?
here's my example:
?php
$x = new test();
echo hey;
// IF next line is uncommented so it manually flushes
// then the finish method WILL get called. But I need
// get around calling anything at the *end* of a script.
//ob_end_flush();
class test {
var $msg_file = cooked_html/error_log2;
function test() {
ob_start(array($this, finish));
$this-msg(got to initialize);
}
function finish($page) {
$this-msg(GOT TO FINISH!!!);
return $page;
}
function msg ($msg) {
$msg = \n . exec(date) . ::: . $msg;
$fp = fopen($this-msg_file, a) or die (cannot open
.$this-msg_file);
fputs ($fp, $msg, strlen($msg)) or die (cannot write to
.$this-msg_file);
fclose($fp);
}
}
?
But if ob_end_flush() IS called then the error log WILL have the GOT TO
FINISH message.
Any ideas on why the output is not being flushed automatically?

This won't work anyway since your class test is declared after using it -
it should be the other way 'round:
class test {}
$x = new test();

if( !function_exists(ob_end_clean_all) ) {
function ob_end_clean_all () {
while ( ob_get_level() ) {
ob_end_clean();
}
}
}
ob_start(ob_spit_content_length);
ob_start(ob_gzhandler);
print There is lots of stuff right here!;
ob_end_clean_all();
/* End of code snippet */
I am running PHP 4.3.0 and my desire is to compress all output (if
browser supports) and also send the content-length header rather than
sending chunked so that my output looks as close to static as possible.
My understanding is that ob_start can be nested and since I registered
ob_spit_content_length first and then ob_gzhandler second that
ob_gzhandler will run first and therefor $buffer being send to
ob_spit_content_length with either be clear text browser does not
support compression or the compress version of the page. Either way
strlen will get me my length.
Well I get very strang effects and as soon as I comment out my 2 ob_start
calls every think works fine. Often times op_spit_content_length will
say 0 bytes even though I *KNOW* output was sent.
Am I missing something here? Did I layer things wrong? Any suggestions
would be much appreciated.
Thanks,
Serge.

[PHP] ob_start
I wish to compress some data using
ob_start(ob_gzhandler);
I use
if(strstr($_SERVER['HTTP_ACCEPT_ENCODING'],gzip)) {
ob_start(ob_gzhandler);
} else {
ob_start();
}
but the compression is never used..
obstart is always used withouth the gz_handler
is there a way around this? or am I doing something
wrong here?
Kind regards
kevin

Shouldn't gzip be in quotes, here?? The second argument to strstr...

Re: [PHP] ob_start
I don't think you need to do the
if(strstr($_SERVER['HTTP_ACCEPT_ENCODING'],gzip)) {
because ob_start(ob_gzhandler); checks to see if the browser will accept
gzip content before gzipping it..
But I think the reason that it isn't working for you is that you don't have
the correct compression libraries compiled into PHP... I spent ages trying
to figure out why mind didn't work and this was the problem. The anonying
thing is that if you don't have this libs it doesn't even tell you

The second argument to strstr... indeed, that fixes that.. thanks now, I have a problem with mozilla and netscape. Although they both accept the ob_start(ob_gzhandler); netscape gives a comunication error, and mozilla just a blank page, IE on the Mac however displays the output. The blank page in mozilla is mentioned in the manual, but how do get around this??

[PHP] ob_start('gz_handler') and session_start()
Is there a way to make ob_start('gz_handler') work with session_start()?
I got them each working independently -- however, when I try to compress a
session -- my page just comes up blank.
?
ob_start('gz_handler');
session_start();
// code and html
ob_end_flush();
ob_end_clean();
?
Or, is there another alternative? -- I'd like to use sessions and I'd
(definitely) like to compress my pages.
Thanks

[PHP] ob_start() and ob_gzhandler
Just wondering what would cause the following: I have a 512/128 cable connection through my ISP that I'm hosting my sites through. I have a 10gb/mo transfer limit (u/l and d/l) so when I saw mention of the ob_gzhandler (and mod_gzip for Apache), that kind of got me interested in it. Anyway, I created a test page, put -just- ?php ob_start(); ? at the top, then some lines of HTML, and loaded it. I got all the HTML code displayed - shouldn't I have gotten a white screen since I had no ?php ob_flush(); ? tag at the bottom? This isn't making sense. Then I tried ?php ob_start(ob_gzhandler); ? and ?php ob_flush(); ? at the bottom - same results. Am I doing something wrong? Shouldn't the ob_start() by itself just load all output into a buffer and not display it until I call ob_flush ()? And how would I know if ob_gzhandler works? I'm running PHP and Apache on Windoze, PHP is version 4.2.0 I think, Apache is 1.3.something.

Re: [PHP] ob_start() and ob_gzhandler
Hmmm... So if I -wanted- to buffer the entire page using ob_gzhandler, I wouldn't use ob_implicit_flush(), correct? Or would this be beneficial in this case? The way I read the manual page on ob_implicit_flush() is that it flushes after each output call. Would that mean that ob_start(ob_gzhandler) would compress the output, then ob_implicit_flush() would display that compressed output at each call? Either way, is there any way to tell if my output is really being compressed by ob_gzhandler?

Re: [PHP] ob_start() and ob_gzhandler
You can just set output_handler in your php.ini file to automatically buffer and compress everything. On Fri, 17 May 2002, Jason Soza wrote: Hmmm...
