[PHP] Alternative session control system
Hello, I need an alternative session control system different from the PHP standard one, that does not need to use the headers, because it's for a series of scripts that will be accessed through AJAX javascript code inserted in different places of a web page which headers I do not control, so I cannot do an start_session before headers sent or setcookies neither. I have an idea on how to solve this, based on client IP, but if there is something done yet, I do not want to reinvent the wheel from scratch.

[PHP] Problems with CURL using an HTTP Proxy on PHP5
Hello,
The following code is failing and I do not find the cause (please, note
that checkurl value and CURLOPT_PROXY are NOT the real values I'm using,
of course):
$ch = curl_init();
$checkurl = 'http://mycheckhost.com/';
curl_setopt ($ch, CURLOPT_TIMEOUT, 6000);
curl_setopt ($ch, CURLOPT_URL, $checkurl);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_HEADER, false);
curl_setopt ($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt ($ch, CURLOPT_PROXY, '1.2.3.4:' );
$data = curl_exec($ch);
$curl_info = curl_getinfo ($ch);
if ( $data === false ) {
$rtn = false;
} else {
$rtn = true;
}
return $rtn;
Every curl_exec returns false, and a var_dump of $curl_info looks as
follows:
array(21) {
[url]=
string(25) http://mycheckhost.com/;
[content_type]=
NULL
[http_code]=
int(0)
[header_size]=
int(0)
[request_size]=
int(99)
[filetime]=
int(-1)
[ssl_verify_result]=
int(0)
[redirect_count]=
int(0)
[total_time]=
float(1.843925)
[namelookup_time]=
float(0.00018)
[connect_time]=
float(0.333015)
[pretransfer_time]=
float(0)
[size_upload]=
float(0)
[size_download]=
float(0)
[speed_download]=
float(0)
[speed_upload]=
float(0)
[download_content_length]=
float(-1)
[upload_content_length]=
float(-1)
[starttransfer_time]=
float(0)
[redirect_time]=
float(0)
[certinfo]=
array(0) {
}
}
I know it is NOT a problem with the website, because if I comment out
the line curl_setopt ($ch, CURLOPT_HTTPPROXYTUNNEL, 1) disabling the use
of a proxy, it works fine.
I know the proxy is working fine, because if I use curl from command
line like:
curl -x 1.2.3.4: http://mycheckhost.com/
It also WORKS fine.
So the problem may be or within the PHP5 curl implementation, or in my
own code, but I have not been able to find the problem with my code.
Any hints?

[PHP] Problems with proc_open and getmypid
Hello, I'm developing a PHP application that runs on GNU/Linux with php cli. A process must launch another one and store its pid, so I use proc_open and then proc_status to achieve that. The child process must also get its own pid and write it down to a file. After that, the calling process should compare both pids and they should match, but in fact they shoudln't. The problem is that when calling to proc_open like: $res = proc_open (/usr/bin/php proc2.php, array(), $pipes); Two processes are created, one for the sh shell that launchs the php interpreter, and another for the php interpreter itself. Also, it seems like proc_get_status($res) returns the status of the sh, while getmypid in the second process returns the pid of the php interpreter. I wonder if there's anyway of do something of these: a) Get the pid of the php interpreter on proc_open instead of the sh one on the parent process, or... b) Get the pid of the sh process instead of the php interpreter on the child process. Or any manner in which two pids matches. Thanks a lot in advance, -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ops!, Better this one:

$result = mysql_query($query);
if ( ! $result ) {
die (Could not perform query $query: .mysql_error().\n);

I did copy and paste from my own code and you've not $query defined on
your one. I prefer to store first the query on a string to show it
complete if there's an error late, because it may show also the point.

[PHP] My objects eats too much (and weird!) memory
Hello!
I'm new here, so I do not know if attachments are allowed, so I put my
code below.
I've written this to check memory consumption of PHP5 objects, because
I'm having memory problems with an OO XMLParser that I've written.
When I execute the code from cli, I get:
$ php MemTest.php
Obj1 uses 208 bytes
Obj2 uses 168 bytes
Obj3 uses 200 bytes
Obj4 uses 200 bytes
Obj5 uses 200 bytes
Obj6 uses 200 bytes
I understand that first instance may be bigger than next ones because
method allocation and other things of that kind, but I do not understand
why second instance is smaller than third :-?
So, my first question is: Why third object is a 16% smaller than third
and nexts?
In any case, my second question is: Isn't too much memory 200 bytes for
a so simply object??
And the third: Is there any manner to get more compact objects in PHP5?
Thanks a lot in advance.

[PHP] [SOLUTION] Re: [PHP] Objects and sessions
Thomas Munz wrote:
I think, its not possible to init an Objeect on a session.
Yes, it can.
The problem was with serialization. With session.auto_start set to 1 on
php.ini, seems like session's objects are unserialized before loading
the script, so the class is not loaded when the session unserialized the
object, and therefore it fails to unserialize it as an instance of its
class.
Setting session.auto_start to 0 on php.ini you should take care of
resume sessions calling session_start() each time, but you can put that
call after class definition, so the object will be unserialized after,
so the problem is solved.
This code works fine:
?php
class SessionTestC {
protected $value;
function __construct ( $val ) {
$this-value = $val;
}
function GetValue () {
return $this-value;
}
}
if ( isset ($_GET['close_session'])) {
unset ($_SESSION);
session_start ();
session_destroy ();
}
session_start ();
if ( isset ($_SESSION['TestObj'])) {
echo 'TestObj is an instance of

echo 'pre';
print_r ($SESSION['TestObj']);
echo '/pre';
echo a
href='.basename($_SERVER['PHP_SELF']).?close_session=1'Close
session./abr;
echo 'Session Test is set to: '.$_SESSION['TestObj']-GetValue().'br';
} else {
echo 'Session Test was not set.br';
$_SESSION['TestObj'] = new SessionTestC ( 'This is a test' );
echo a href='.basename($_SERVER['PHP_SELF']).'Click here./abr;
}

BTW, I do not know if the code I've used to destroy the session is the
best, but this is a secondary issue...

If each element of the array is a string with those contains, it should be sorted as you want just calling sort function.

Re: [PHP] Unexpected results with object to array cast
Forget it, it has a lot of sense since self is a reference to the object itself, but the new array is not in the same memory than the source object, so result cannot be as I expected because self is no really self within the array, but a reference to an object outside it. The result its perfectly logical, indeed. Francisco M.

Re: [PHP] Re: VOTE TODAY
This is my second and last message on this issue.
Perhaps this list is not the best place to discuse about politics, but
it isn't for create and follow personal issues neither. In my (not-so
:-P) humble opinion everyone that follows this kind of threads is as
guilty of making noise as the one who begins it (and that's include
me.php, indeed).
I think politics are rather important, a lot of more relevant than
coding -just read a bit of History-, greeks had a word for those that
doesn't care about politics, that translated to english is IDIOT, but I
also agree that this is not the best place to discusse about that. Use
www.kuro5hin.org by example instead.

[PHP] [SOLUTION] Re: [PHP] Convert an array in an object instance
Ok, I've write a function that emulates the Perl's bless one. It works

Re: [PHP] [SOLUTION] Re: [PHP] Convert an array in an object instance
Erm... I've seen there're some aspects to perform... it fails because
the name of the members is changed during conversion to the array. It
puts the class name using '\0' (0 is a zero, not a caps 'o') character
as separator before member name in private and an '*' in protected.
It's not an unaffordable issue, because you still can modify array
values having this in account. For example, if you want to modify the
$One private member in the array, you cannot do:
$Clone['One']=5;
you should do
$Clone[\0TestClass\0One]=5;
instead.
Anyway I think it should be easily fixed (when I've time to do it, now I
must work in another thing :-| )

[PHP] bless function
Ok, I think I've got it now. The code is autoexplicative, the only
restriction is that the object must be converted to an array using the
function obj2array instead of a direct cast. There's another ways to do
this without the needless of that obj2array function, but I think this
is not really a limitation.
Here it is:
?
function obj2array ( $Instance ) {
$clone = (array) $Instance;
$rtn = $clone;
while ( list ($key, $value) = each ($clone) ) {
$aux = explode (\0, $key);
$newkey = $aux[count($aux)-1];
if ( $newkey != $key ) {
$rtn[$newkey] = $rtn[$key];
$rtn['___FAKE_KEYS_'][] = $newkey;
}
}
return $rtn;
}
function bless ( $Instance, $Class ) {
if ( ! (is_array ($Instance) ) ) {
return NULL;
}
// First drop faked keys if available
foreach ( $Instance['___FAKE_KEYS_'] as $fake_key ) {
unset ($Instance[$fake_key]);
}
unset ( $Instance['___FAKE_KEYS_'] );
// Get serialization data from array
$serdata = serialize ( $Instance );

In the real world (tm) there's no effective protection for this kind of things.

[PHP] Add methods to object dinamically
I've seen that's possible to add members to objects dinamically, in example:
class MyClass {
private $a;
}
$MyObject = new MyClass ();
$MyObject-b = 1;
Now $MyObject has a public member called 'b' that has a value of '1'.
The question is, is it possible to add methods in the same way?
I meant something such as:
function sum ( $this ) {
return $this-a+$this-b;
}
$MyObject-sum = sum;
Note that code will not work, but it illustrates what I'm asking for.
TIA.
