[PHP] call-time pass-by-reference feature really deprecated?
Hi, I just got a warning message on a system using php version 4.3.1: Warning: Call-time pass-by-reference has been deprecated - argument passed by value; If you would like to pass it by reference, modify the declaration of [runtime function name](). If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. However, future versions may not support this any longer. This msg does not appear on my machine running php 4.3.2. Maybe it's because of the different configuration? Will the pass-by-reference feature really be dropped?! Many software design patterns wouldn't be possible anymore! It's an essential feature. The config of the system throwing the warning is: './configure' '--with-mysql=/usr/local/mysql/' '--with-apache=../apache_1.3.27/' '--enable-track-vars' '--with-config-file-path=/etc/' '--with-imap=/usr/local/imap-2001a' '--with-gettext' '--with-exec-dir=/usr/local/typo3sh/bin' '--with-gd=/usr/local/typo3sh' '--with-jpeg-dir' '--with-png-dir' '--with-tiff-dir' '--with-ttf=/usr/local/typo3sh' '--with-zlib=yes' '--enable-gd-nativ-ttf' '--enable-ftp' '--with-xml' /dorgon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

yes. there is:

"pass-by-reference" has not been dropped, it is "Call-time pass-by-reference"
which is being deprecated.
so call-time pass-by-reference is giving parameters as reference to
functions, e.g.
function returnObjectToAccumulator(&$obj) {...}
If this feature is really dropped, how would you implement
ConnectionPools for DB-connections for instance, or any classes
managing a set of object and providing them by returning references?
many OOP design patterns (primarily adopted from java) would not be
possible anymore. I think this would be worth talking about.
Is there any plausible reason for that decision?

[PHP] Re: call-time pass-by-reference feature really deprecated?
whats the difference?
call-time-pass... is function callMe(&$obj) {...}
and pass-by-ref is "return &$obj" ?
I'm not sure if I got you.

I think call-pass-by-reference is going away, but pass-by-reference is going
to be default in PHP5.

Isn't Call-time pass-by-reference the following

myFunction1() is defined as function myFunction1($x)
Where as pass-be-reference is called as

I think the latter is better anyways, because the caller shouldn't know the
internals of the function, so you don't know if the function will copy the
argument and use that instead.

"Call-time pass-by-reference"
=
function doo($i_may_or_may_not_be_a_reference) {
$i_may_or_may_not_be_a_reference++;
}
$i = 1;
doo($i);
echo $i; // 1
doo(&$i);
echo $i; // 2
// here doo() is not defined to have parameters passed by reference. The
decision on whether to pass by reference is made at run-time, hence call-time
pass-by-reference. It is this behaviour which is being deprecated.
So in the newer versions of PHP if call-time pass-by-reference is disabled and
you wish to pass parameters by reference you'll have to define your functions
accordingly:
function doo(&$i_am_passed_by_reference) { ... }

[PHP] open_basedir
hi folks, I just realised that open_basedir also prevents the access to /tmp. Thus, file uploads aren't possible. One solution would be, to use a tmp directory within open_basedir, to give PHP the required write access. But assume you're using a server with multiple VirtualHosts and www-dirs. You use open_basedir to limit the access of every script running in a specific VirtualHost/www-dir to its proper www-dir. Now you would have to create a .../tmp directory for each single www-dir, which is not very pretty. Would it be possible to limit access to open_basedir without the exception of /tmp, to allow the uploads? /dorgon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] identify not only browser, but even browser windows with session
hi, does anybody know how I could identify the browser window? my problem is, that i have a application framework and I want to use multiple windows providing different GUIs. Each window should be able to send a request and send a proper session key or unique key which identifies the application window. I cannot use get/post parameters, because the framework works in a different way and uses the path info. i also don't want to use the path info to pass through the window key. can cookies be stored for single browser instances (windows)? does the browser send some information that could be uses? thanks in advance, dorgon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] identify not only browser, but even browser windows
I thought so One solution would be not to use cookies and pass different unique ids from each window. thx dorgon Ernest E Vogelsinger wrote: At 10:58 24.06.2003, dorgon said: [snip] can cookies be stored for single browser instances (windows)? does the browser send some information that could be uses? [snip] Short answer - no, and no. Cookies are stored browser-wide, and if the user presses Ctrl+N (or else) to open a new window you would never detect it. Even using some sophisticated techniques like session access counters, session serial numbers, etc, are not guaranteed to work since the browser may have cached the page contents and simply _locally_ copied it to the new window, not issuing a new request. However you may use a serial number in session data that is incremented with each request. Incorporate this number in any form or session-based link to have the browser transmit it back to you. Then compare if the serial number matches the expected vale; if not it's a reload and you can proceed as seems fit. However you don't have a chance to recognize if the reload comes from simply a page reload, or from a window clone. BTW - this is the reason I have switched off session cookies at my servers. Having the SID available allows to run more than one session from a single browser instance. HTH, -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] php caches mysql connections to same host
Is this a bug or a feature? I realised that php caches mysql connection even when not using persistent connections! When calling mysql_connect(...host...) twice, and not closing to first connection I get the same resource #id the first connection has. I noticed that, when writing a connectionPool, that opens n connections to different DSN (data source names, that specify dbms://user:[EMAIL PROTECTED]/db in one string). The problem raises, when I have to different connections to the same mysql host but different databases. Then the second connection is taking the first, but the first is used by another class. The only solution is to do a mysql_select_db before every query. Is this a bug or a feature? /dorgon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: php caches mysql connections to same host
for better understanding:
$conn1 = mysql_connect("localhost", "user", "pwd");
mysql_select_db("database1", $conn1);
$conn2 = mysql_connect("localhost", "user", "pwd");
mysql_select_db("database2", $conn2); // select two diff. DBs
echo $conn1."";
echo $conn2."";
returns:
Resource id #2
Resource id #2
BUT:
$conn1 = mysql_connect("127.0.0.1", "user", "pwd");
mysql_select_db("database1", $conn1);
$conn2 = mysql_connect("localhost", "user", "pwd");
mysql_select_db("database2", $conn2); // select two diff. DBs
...returns two different resource IDs (which I'd like to have).
When using mysql_pconnect I'm always getting correctly different
resource ids.

Okay so I have a client that would like something output to a word document. I already have HTML and PDF versions... I'm trying to figure out the best way to do this. I am already aware of the open html in word hack. The way I see it, these are my choices: 1) Use the hack that I'm really don't like. It never looks quite right (which is the whole point of this). 2) Move everything over to a windows host and use COM. 3) Somehow convice host (hurricane electric) to run PHP5 CVS w/ Sterling's mono extension, and use .net to create the word document (does mono support that class yet?). I hate C#. VB is even worse. 4) Find an open-source library that writes word documents (quick search revealed nothing...), write an extension for php. 5) Find a spec for word docs and write a library in php 6) find a spec and write a library in c, then create php extension. I'm willing to do this, but it would take a long time... 7) Tell my boss to sod off (politely, though), it's not currently feasible... I think this is what he's expecting, anyways.

this is correct. but variables will not be equaled in the
string. so when using '' brackets, you cant write
$var = 'hello $name!'. even escape chars (\n, etc.) aren't
resolved.
3. $_SESSION["test"]
this is best practise for most cases. you can write variables

Re: [PHP] Re: generate word docs
If you know what you want your word doc to look like, set it up in Word, or whatever will save a formatted rtf file (Sorry, I'm Windows/Mac based, but I presume that Open Office etc will do this on Linux). I'm not sure if I got you, but RTF as very different from native word format. RTF doesn't allow you to place images or other floating objects. I don't know if tables and borders are possible. Tabulatur sometimes can't fit your needs. I insert placeholders into the document where I want to put dynamic data I use %_varname_% to avoid any RTF conflicts. this idea really sounds great. a faster way can't hardly be found. /dorgon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
