[PHP] Problem: Only 1 fsockopen() connection for apache at a time.
Hello all. I have a script that uses fsockopen() to connect to a remote server/port and from what i am seeing mod_php4 with apache only allows 1 fsockopen connection at a time and will que the other fsockopen calls and then process them when the one before it has closed. Is there a way round this? What i am after is for somebody to be able to goto the php page which will then connect via fsockopen to the other server do its send/read stuff and then produce the output. At the moment if one pages takes a bit of time to finish the remote connection then all the other apache processes just sit there and wait for it. The remote server only ever gets 1 connection at a time even though there are free connections available. Has anybody else seen this or know of a way around it. -- Regards, William Bailey.

This is all done via HTTP headers.
example:
header('Content-type: application/octet-stream');
header(sprintf('Content-disposition: inline; filename=%s', $fileName));
header(sprintf('Content-length: %d', $fileLength));
// Output file now.
Hope this helps.

[PHP] Adding to md5 checksums.
Hi all,
Just wondering if it is possiable to add or combine 2 or more md5 checksums
togeather?
Basically i've got a value/file that i can get the md5 checksum for but want
to be able to padd the input value/file with nulls to a specific length
example:
value is : abcdef
block size : 4 chars
Therefore i want to get the md5 value of "abcdef\x00\x00".
The above example is very small and i could just recreate the string in
memmory but i will need to do this with much bigger values/files and don't
want to have to use silly amounts of memmory.
Maybe it would be an idea to add another parameter to the built in md5()
function that specifies the starting md5 example:
$checksum=md5("\x00\x00", md5("adcdef"));
would return the same checksum as:
$checksum=md5("abcdef\x00\x00");

[PHP] How can one find out what Headers have been sent by a script.
Hello all,
Does anybody know of a way that i can check to see if a header has already
been sent by a script?
I am currently finishing a class that has a few functions registered with
register_shutdown_function(). They take care of database updates and general
clean up for that object and i want to be able to perform a different action
depending on if, for example, a 'Location:' header has been sent.
Is there any way i can get a list of headers already sent from a script?
I know i could write a custom myHeader() type function that stores the sent
headers in a variable and then read it back but i want something that i can
add to my class and not have to make any changes to other scripts. The class
im currently working on is just supposed to be dropped in and is then
expected to run without the need to update anything else.
Thanks in advance.

[PHP] seems like magic_quotes_gpc is turning itsself on!
-BEGIN PGP SIGNED MESSAGE-

Hi All,
I have a strange problem with one of the sites i work on and provide
support for. I the following block of code that checks to see if
magic_quotes_gpc is enabled and if it is it dies with an error message:
if((integer)ini_get('magic_quotes_gpc')!=0){
~debug('Magic Quotes GPC is currently active. Please disable.');
}
The debug functoin just displays a sorry message on the browser and
emails the description and the serialized $GLOBALS variable back to me.
in the php.ini i have the following:
; Magic quotes for incoming GET/POST/Cookie data.
magic_quotes_gpc = Off
Now every so often say at most 1 in 100 hits a user will see the sorry
screen and i get a call back email and every time its the same issue
'Magic Quotes GPC is currently active. Please disable.'
Anybody have any ideas on where to look?

It can be on any page.
The magic_quotes_gpc check takes place in a settings.php file which is
always the first thing included for every php page for this site. It has
a number of define statements and a few other includes and thats about
it. No database connections or anything else apart from class and
function declarations have taken place.

[PHP] PHP5 interfaces
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi all,
I am currently starting a new personal project and thought that i would
start to implement it in PHP5. Now the new object model in PHP5 is
really nice and haveing objects bassed by reference by default saves a
lot of head aches :)
My question however probably comes from my lack of OO understanding.
Lets say i have the following class:
Final class Statistic {
~function __construct ($min, $max, $initValue=0) {
~}
~public function setValue ($value, $strict = false) {
~}
~public function applyDelta ($delta, $strict = false) {
~}
~public function getValue () {
~}
}
I want to implement some kind of onChange function and from what i can
see that i have 2 options:
1. Create an OnChange object and make Statistic a child class.
2. Create an OnCHange interface and make Statistic implement it.
The problem is that nither are fully what i'm after. I want to be able
to use the onChange functionality on a number of other classes (all
implemented in the same way) and i also want to create a few other
onBlah functions that i also want to apply to objects along side if
required the onChange functionality.
So from this i can see that an interface would be the best way to go as
a class can implement any number of interfaces but can only be extend
from one parent. However using the example given all the onChange
functions for each object function exactly the same and will therefore
give me a lot of repeated code.
Is there any way to get around this. Something like an interface with a
fully defined function is what i'm really after.
The onChange function is currently...
~public function onChange ($object=null, $method=null) {
~if($object == null){
~$method = null;
~}
~if($object != null && !is_object($object)){
~$this->onChange();
~}else{
~$this->onChangeObject = $object;
~$this->onChangeMethod = $method;
~}
~ }

[PHP] Getting the required GD Memmory Usage.
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi All,
I have a site that loads images with the built in GD functions. Most of
the images are small and load fine however there are a few images that
are large and when trying to load them causes php to exit with the
unable to allocate memory message. I was wondering if anybody knows of a
way to look at a file (in this case a JPEG) and then calculate the
memory requirements required for GD to load it.
I know that i can just set the memory limit value to a higher value but
i don't want to load these large images anyway so if i could work out
the GD memory requirement without having to load the image it would be
most useful.

Sorry but thats not what i'm after. I want to know the available memory
needed to load the image. The default php memory limit is 8M and if the
image is large php is not able to load it because the 8M limit is
reached and therefore causes php to error out.
Is there a way to calculate the memory required to load the image
without haveing to load it? Would the following work...
$memSize = $imageWidth * $imageHeight * 4
This assumes that gd uses 32bits per pixel.

[PHP] include & include_once, how do they work?
I have just been playing around with include and include_once with one of
my classes, basicly there are a lot of functions inside this class so we
have put the contance of the function into its own file (so that different
people can work on it) and are useing the include function to call it.
example:
...
function getCategorys ($id=0) {
return include($this->functionDirectory
."getCategorys.inc.php");
}
function listItemsByCategory ($id,$start=0,$dynamic=FALSE) {
return include($this->functionDirectory
."listItemsByCategory.inc.php");
}
...
At one point I was useing include_once thinking that it would load the file
once and then keep it in memmory untill the script exited, but this dosen't
seem to be the case. What happens it that you call the function once and it
works fine but if you call it again it returns nothing so I have therefore
had to use include, which will load the file every time and it works.
Anyway to my question: Is there a way to keep code in different files and
have php load the file once and then keep the code in memmory once it has
been called?
Thanks,
William.

[PHP] Variables in 'friendly' urls
Hi, Is there a way to pass variables as 'friendly' urls? So instead of haveing a url like www.blah.co.uk/profile.php?team=tigers i could have www.blah.co.uk/profile.php/team/tigers which would call profile.php and set team to tigers. I've been playing with it but i can't seem to get it to set the variables. It will run the script (profile.php) but the variable $team if still unset.

[PHP] PHP cgi/standalone script issue.
Hi All, Just need a bit of help on an issue i currently have. I have a php script that is being called like a cgi and am trying to read stdin so that i can get the raw http data that is being passed to apache. My problem is that it all works fine outside the web environment but as soon as i call the script over the net then it dosent work as expected. What it looks like its doing is that the script is being run by apache just lke any other cgi script but because php knows that its currently in a web environment it automaticly processes the data and setups the global variables itsself, which i dont want it to do. Basicly i want to get it to run as if i had run it from the command line. Below is the current code im using, as well as a very small shell script that does what i want php to do just so that you can see what im going on about. PHP SCRIPT: #!/usr/local/bin/php -q SHELL SCRIPT: #!/bin/sh while read stdin do echo $stdin >> /tmp/upload done echo Content-type: text/plain echo echo done. And i know that php does file uploads by its self, but i need to get the data as it comes in and not save it to the filesystem.

[PHP] RSA Encryption with PHP (code attached)
Hi all,
I currently trying to get RSA encryption working in PHP and have
came up against a few issues that i hope somebody on here will be able to
help me with.
Basicly i have it mostly working and am able to generate keys OK
and i can also encrypt/decrypt data that will fit into one message 'block'
(their is currently no code to split a message up into blocks for
encryption). The problem i have it that sometimes the encryption dosent
seem to work correctly. I think that it is do to with me converting data
back and forth between different bases and am 'losing' information
somewhere along the line.
Well if anybody on this list knows a bit about encryption or if
you just want to help i would be very great full if you could look at the
attached code and comment on where my problem might be coming from.
I am making use of the gpm library so you will need that
installed before you are able to run my code.
Also please cc me directly on a any responses as they will get to
me quicker then by just emailing the list alone.
Regards,
William.

[PHP] Help needed with speading up a function.
Hello again.
I have the following function that generates a prime number of x
bits. It seems to work but i am just trying to see if i can make it any
faster as generateing 1024 bit prime can take a while. so i thoought i
would ask here to see if anybody has any ideas or suggestions.
The function is as follows:
mt_srand((double)microtime()*1);
function generate_prime ($bits) {
$number=gmp_init('0');
for($i=$bits; $i>=0; $i--){
$rand=mt_rand()%2;
gmp_setbit($number, $i, $rand);
}
while(gmp_prob_prime($number)<1){
$number=gmp_add($number, 1);
}
if(strlen(gmp_strval($number, 2))!=$bits){
$number=generate_prime($bits);
}else{
return (string)gmp_strval($number);
}
}
At the moment im generating a random number of the required length and
then +1ing it untill it is a prime. I suppose i really want to know if
their is some way of knowing how close you are to a possiable prime so
that if the random number is too far away then it could call itself again
and try a different random start location.
I look forward to any ideas that you might have.
Regards,
William.

${sprintf('$%s', $section)}.=$pData;

it works and all is well. I don't really want to use eval() and just
wanted to see if anybody has any ideas why the above doesn't work.

Hi All,
After having been talking to lots of people in irc lately who are

[PHP] How does one get strtotime() real NOW now that the function behaves according to GNU date syntax?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi All,
Now that the strtotime() function behaves in according to GNU date
syntax (which i feel should not have changed in a minor php version bump
but thats a different issue) how does one implement something like the
old system?
Lets say, for example, that i want to get the timestamp for 2 seconds
in the future, before i could have just done:
$t = strtotime('NOW + 2 seconds');
But since the change this will no longer work as you will get the
correct day but with a time of 00:00:02.
I have tried the following but this fails and results in -1:
$t = strtotime('@'.time().' + 2 seconds')
p.s. I know that for the example posted i could just do:
$t = time() +2
But i also want situations where i could have 'next thursday + 3 hours'
etc.

[PHP] PHP5 simpleXML bug or am i just being silly :)
Hi All,
I am currently working with PHP5 beta and have found something strange
with the simplexml objects. It seems to be forgetting its values. Below
is an example..
[[the PHP5 code]]
print('');
print('$this->user::');
print_r($this->user);
print('$this->user->site::');
print_r($this->user->site);
print('$this->user->site[0]::');
print_r($this->user->site[0]);
die('');
[[END]]
[[the PHP5 Browser Output]]
$this->user::
simplexml_element Object
(
[login] => wb
[password] => 3c1175c6cdf614fb006cee10fdc325e3aa0f1894
[site] => Array
(
[0] => www.pro-net.co.uk
[1] => www.example.com
)
)
$this->user->site::
Array
(
[0] => simplexml_element Object
(
)
[1] => simplexml_element Object
(
)
)
$this->user->site[0]::
simplexml_element Object
(
)
[[END]]
Shouldn't $this->user->site return the Array displayed in the output
for $this->user or even shouldn't the simplexml_element Objects for
$this->user->site have a value or something. Basically they shouldn't be
blank otherwise how to you get the data?

[PHP] SimpleXML node detection.
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Morning all,
Hopefully a quick question i need to check if a node exists for a
SimpleXML object but no matter how i try i simple cant find a way to do
this as it always creates a new object even if the node dosen't exist in
the xml document.
My peoblem is that i have something like the following xml...
~
~foo
~foo
~
~
~
~blah
~blah
~
Where there is an ignore tag to specify that i ignore that item
Any ideas on how i can check to see it the ignore node exists or not?
