I'm quite used to getting 'bogusbotted' by now - you seem to have to fight for every bug, in code or documentation. I appreciate that the maintainers have to deal with a lot of crap, and I make an effort not to waste their time (e.g. by reading docs, searching archives, posting on -users, as they suggest), but occasionally they just don't read the report - in this case I was referred to the documentation, which agrees 100% with my complaint!

[PHP] Object to array conversion oddity
A simple class like this:
class Myclass() {
public $field1 = '';
private $field2 = '';
public function __sleep() {
return array('field1', 'field2');
}
}
$myclass = new Myclass;
If I var_dump this, I get:
object(Myclass)#6 (2) {
[field1]=
string(0)
[field2:private]=
string(0)
}
If I coerce this to an array:
$arr = (array)$myclass;
the properties change names in a most unhelpful way:
array(2) {
[field1]=
string(0)
[Myclassfield2]=
string(0)
}
The docs (http://www.php.net/manual/en/language.types.array.php) say:
If you convert an object to an array, you get the properties (member
variables) of that object as the array's elements. The keys are the
member variable names.
It seems that's not quite true.
How can I stop it doing this? Looks a bit buggy to me.

I would guess that it does this to make sure you know what you're doing and using the private variable like that. I'm just guessing at that point though. Well, I realised that, but it's not very helpful as there's no separator between class name and variable name it's impossible to separate it correctly - if I had happened to have a property called 'myclassfield1', I would not be able to tell if the real property name was 'myclassfield1' or a private property called 'field1'. If it is going to stray from the documented behaviour, It would be far more useful to retain the names that the var_dump on the object uses - 'field1:private'. That's safe as : is not a value char in a variable name, but it's fine as an array index. Try a test with multiple public and multiple private variables. If the format of the array keys stays the same, then you should have your answer. In my real code I do have multiple fields all exhibiting this behaviour. I'll report it.

Re: [PHP] Object to array conversion oddity
Here's a more accurate example:
?php
class Myclass {
public $field1 = '';
private $field2 = '';
protected $field3 = '';
}
$myclass = new Myclass;
var_dump($myclass);
var_dump((array)$myclass);
?
This produces:
object(Myclass)#1 (3) {
[field1]=
string(0)
[field2:private]=
string(0)
[field3:protected]=
string(0)
}
array(3) {
[field1]=
string(0)
[Myclassfield2]=
string(0)
[*field3]=
string(0)
}
So it seems protected fields behave differently too.

Sure, but don't you think that coding should at least try to be driven by logic rather than luck? I'm also not denying that it's not too hard to work around (with a function not dissimilar to what you suggested), but I'd really prefer it if it just did what it says on the tin. By its very nature, casting from object to array indicates that you no longer want the constraints of property protection, which an array can't preserve anyway, and it's not as if there are not intentional, documented methods of obtaining this information. It sounds like they've helped out by giving more data than was necessary. ...and in doing so defaults to breaking code that expects it to behave like the documentation says it does? I don't think I'd classify that as helping out. Bear in mind that my code broke in exactly this way. If you want to find out what the access level of a property is, I doubt your first thought would be to convert it to an array - and I bet you didn't know that this info was even there because it's not documented, thus helping nobody. This is what introspection is for. I don't have a problem with being provided with extra information, just as long as it doesn't interfere with correct operation, which is what it currently does. It could provide the extra info in a marginally less destructive way, for example by adding 'private' and 'protected' array properties containing field names for each access level to the resulting array. OTOH, that would break what you'd expect count() to deliver after the conversion. I really think it should just do what's it's meant to, and no more.

Since reflection gives access to all this information, why bother trying to squeeze the same info into an array-shaped container that just can't hold all the same info without corrupting it? I can see that there might be some reason for converting the object with additional information in some circumstances (much like serialization to strings does), but here we're only talking about casting, which should be a 'best-fit' data matter. The behaviour we've got would be better served with a function like toArrayPreservingClassInfo() rather than the default casting behaviour. Since reporting the bug (which was immediately marked as bogus; go figure), I've had something else brought to my attention: The resulting array keys are not what they seem! Their actual structure is: NULLclassnameNULLpropertyname So, here we have undocumented behaviour justified by yet more undocumented behaviour! How behaviour so wildly different to what's documented is not considered a bug I don't know. At least this format can be dismantled reliably, rather than trying to string-match class names. I think trying to preserve this information (as you said) is entirely pointless - it's not as if you can cast back from an array to an object, and I can't think of any circumstances in which it is preferable to using reflection (unless it's a relic from PHP4?). What's next - appending a creation time to integers when they're cast into strings?

based on the other info I've mentioned:
/**

object to array
* The resulting array looks like what the documentation says that
(array)$object delivers, but actually doesn't
* @param object $object The object to convert
* @return array
*/
function object2array($object) {
$class = get_class($object);
$array = (array)$object;
$propArray = array();
$matches = array();
foreach ($array as $key = $value) {
if (preg_match('/^\0(([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)\0
([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*)$/', $key, $matches)) {
//It's a private property
if ($matches[1] == $class) { //Ignore private props of
superclasses
$propArray[$matches[2]] = $value;
}
} elseif (preg_match('/^\0(\*)\0([a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-
\xff]*)$/', $key, $matches)) {
//It's a protected property
$propArray[$matches[2]] = $value;
} else {
//It's a public property
$propArray[$key] = $value;
}
}
return $propArray;
}
Works nicely for me.

Strictly speaking, you should not set a return-path header at all. You should set a 'sender' header, and the return-path header will be generated for you by your MTA. The reason for this is that a message may gain multiple return-path headers on its journey so that its full path can be traced backwards to the source. The common exception to this is if you're on Windows and don't have a local MTA (or on any platform and have PHPMailer's IsSMTP set), and your script is sending directly via SMTP and thus IS the MTA.

Now I just need to go find a borderless chrome package for ff... khtml2jpg is definitely a more advanced solution as it contains its own browser and is thus not limited by screen size - you could grab a page 10,000 pixels tall if you wanted to - and it can monitor browser state e.g. so it can know when all images are loaded instead of just waiting for a bit. Flipside - it's not working for me... Thanks very much for the tip, very glad to have finally found a solution.

Re: [PHP] php5 call by refference

AFAIK, in PHP5 one can't call function with function parameters .
The error is that you only can pass variables by reference.
foo(strlen('aaa'),strlen(''));
You can call functions like that without problems UNLESS the function
is expecting values by reference, i.e. results are passed back
through the parameters. If you supply a function result, then you may
as well not be calling the function as you'll never be able to get a
result back from it, hence the error message. e.g.
function foo($a, $b) {
$a = $a.$b;
}
If you call this as you asked, where would the result go?
Is there some sort of workaround ?
As was suggested, put your values in variables before calling the
function, though the code example you posted suggests you're trying
to do something odd.

Strange as it may seem, you'll probably find that this is the fastest
method:
'first part of string '.(($a==$b)?$c:$d).' rest of string'
I benchmarked this a while ago and was surprised to find that
multiple concats with single quotes are significantly faster than

Yup, I tried this and it kind-of works, but still leads to some weird behaviour. INSTEAD, do this. Create a PHP script, and name it 'x' In .htaccess, force 'x' to be PHP as far as Apache is concerned: Files x ForceType application/x-httpd-php /Files You can now access your x=123 from $_SERVER['PATHINFO'] (or is it 'PATH_INFO'? No more endless tweaking of Regex rules in httpd.conf and logging the mod_rewrite and dinking with ^/[0-9]+ junk and re-starting Apache every time you want to try a change. That's a nice trick - I'll have to remember that. My rules are in .htaccess (as seems normal for 'deployable' systems) so I don't need to restart apache and it's easy to twiddle with them, and besides, I like regexes ;^) The issue isn't really the passing of parameters (which your approach deals with very nicely), it's that PHP gets fooled into thinking that it's somewhere that it's not. The most annoying thing about this problem is that I'm sure it should 'just work', and I know I've seen it do so before in both my scripts and others - Serendipity has an almost identical setup for rewrites and it doesn't do anything special to work with them - all this futzing with paths that mod_rewrite does is long finished by the time that PHP gets to hear about anything - PHP never has to know the real URL, it should be happy to deal with the rewritten one. The problem seems to be that given the incoming URL: /x/123 this gets rewritten to /x.php?x=123 and it does run the correct script in the correct directory, however, once it's running PHP acts as if it had said: /x/x.php?x=123 Which just breaks paths everywhere. I know that this is what the passthrough option is supposed to deal with, but removing it doesn't help either. Maybe I should look more carefully at my RewriteBase etc. I've asked in sitepoint apache forums too, see if anyone there has any idea. Thanks for the ideas.

If you find a browser that lets you configure application/octet-stream to be opened with a specific application, then file a bug report with whomever wrote that browser. There's no such spec for browsers per se (which is why they vary so much) - they are just HTTP clients. I can think of a perfectly reasonable situation where I would want a plugin to handle application/octet-stream - say I'm pulling some arbitrary binary data and while I'm debugging, an in-browser hex dump could be very useful. The other thing is that I may be being forced to use that 'wrong' MIME type to work around bad implementations of content- disposition... I know that's not a common situation, but there should be nothing preventing me from doing it. There are browsers that don't do downloads at all (I've written some), there are others that do nothing but downloads (I use Interarchy for just that).

[PHP] mod_rewrite and include paths
This seems like a simple problem... I have a rewrite like this: RewriteRule ^x/([0-9]+) x.php?x=$1 [PT,L] This maps a url like http://www.example.com/x/123 to http:// www.example.com/x.php?x=123 x.php contains a line to include some class like: require_once 'x.class.php'; My include path contains '.' (plus paths to pear, etc), and the class file is in the top level directory. This configuration will fail with a file not found error. Because of the rewrite, PHP ends up looking for x/x.class.php instead of just x.class.php. If I change the PT option to R (AKA ugly mode), it works fine as PHP gets to know about the real URL. So how can I get PHP to look in /? I can set include_path with a php_value in .htaccess, but I can only set it absolutely (losing existing values), not add to it (AFAIK?). I don't want to add an absolute path to my global include_path as there may be multiple independent deployments of the same scripts on the server, and I don't want them including each others files. Adding .. to the path would work but is a security risk. Any other ideas?

Well, unless you're counting really different addressing standards like X.500, everyone has to operate within RFC2822. You're quite free to put additional constraints on addresses, but should be within that spec, not in addition to it. If an address is not RFC2822 compliant, it's pretty unlikely to work, though I have occasionally seen things like non-ASCII chars and '_' get through.

OK, so PHP may not pass through unset params as NULL (it's not up to
the browser), but if you don't select any checkboxes at all, the
param won't exist, and asking for an index of something that doesn't
exist is normally a good way to generate notices. isset's job is not
to tell you if an array key exists, so why use it for that purpose?
This is the difference I'm on about:
$z = array('a' = 1, 'b' = NULL);
echo array_key_exists('a', $z)?yes\n:no\n;
echo isset($z['a'])?yes\n:no\n;
echo array_key_exists('b', $z)?yes\n:no\n;
echo isset($z['b'])?yes\n:no\n;
This prints:
yes
yes
yes
no
That last 'no' has huge bug potential.
I'm not saying it doesn't have practical use, but I wouldn't call it
good practice, and I wouldn't advise people to do it that way in new
code. As it happens, isset _will_ usually work for things that come
through the web-driven superglobals, but not all arrays come from
there - if you use the same syntax for dealing with databases or your
own objects you could be creating some very entertaining bugs. I
don't know about you but I often deal with arrays containing NULL
values where using isset would be very wrong.

I makes no difference - they will both work. Mine doesn't care where

Your overall match will end up with leading spaces, mine will end up

mine because it has 1 less char ;^)

Sending directly is usually reserved for Windows machines with no local MTA and is usually way slower and doesn't handle queuing. I'd advise anyone to use PHPMailer for mail anyway as it makes it much more reliable to deal with all the other stuff like MIME encoding, plus it has support for all these sending methods without having to change much code.

However, it still serves to underline my other point that using isset without actually knowing that is a potentially dangerous thing. Getting into the habit of using it for looking in the likes of $_REQUEST means you're likely to use it other places where you have no such guarantee, and you'll have a bug to track down. Using array_key_exists means you will never be exposed to this possibility, no matter where your data comes from.

I'll agree it's very dull. isset() does not, under any circumstances, create an index nor a variable. Quite right; I never said it did. Its entire purpose *IS* to tell you if something has been set to a value. That's why it's CALLED isSet But that's not the question you're using isset to answer. You just want to know if something exists - you probably don't even care what its value is. Take apart this operation: $a = isset($myarray['a']); Implicit in this simple line is a 'hidden' step which is to look up the index 'a' in $myarray to get its value before testing if it is set or not. The issue I have is that that step's existence is being overlooked. That line could also be written: $a = !is_null($myarray['a']); Either way, if $myarray['a'] does not exist, its value will be regarded as null (and as such, isset and !is_null would give correct results as a consequence of this convenient side-effect), but I would also fully expect to receive an undefined index notice as you have explicitly looked up an array index that does not exist. If you used other functions the same way you're using isset, you would see nothing wrong with this: $myarray = array(); print $myarray['a']; but I would hope that you would have a problem with that. Why treat isset differently?

No. Given $myarray['a'] = NULL, isset($myarray[a']) returns false.
You're saying that therefore, $myarray['a'] does not exist, which is
clearly untrue. Testing to see whether something has a value is
exactly what isset does, not whether it exists. In many cases it
comes down to the same thing (because if it doesn't exist it can't
have a value), but they are definitely not identical.
Wouldn't it seem like a bug if a function intended to check whether
a variable is set generates a notice when you test a variable that
isn't?
Since we're on such thin ice, you need to tread carefully - first you
said it's for testing to see whether something exists, but now you
describe it as a function intended to check whether a variable is
set. Which is it? They are not the same thing. Here's an experiment
to distinguish which it is - it may come as quite a surprise:
var_dump(isset($bar));
echo $bar;
$bar = NULL;
var_dump(isset($bar));
echo $bar;
bool(false)
PHP Notice: Undefined variable: bar in /test.php on line 3
Notice: Undefined variable: bar in /test.php on line 3
bool(false)
Holy Smoke! isset quite definitely CANNOT tell you if a variable does
not exist - though PHP clearly knows as the second echo did not
generate an error! If it returns true then it does definitely both
exist and has a value (which is useful and why you can use isset as
you do), but if it returns false you really have no idea if the var
exists or not. So what can you use instead? Is there no direct
equivalent of array_key_exists for variables? I did discover that
array_key_exists('bar', get_defined_vars()) works, but though at
least it's definitive, I don't think I could face using that
everywhere ;^)
To summarize, I see nothing wrong with your way of using
array_key_exists(), but I don't think you can claim Richard's use
of isset() is inappropriate. His method is safer in cases where
the array itself is not set, and your method is safer when an
element's value is NULL. Neither of these cases ever exist with
$_GET, $_POST, etc., because they are always set, and they only
contain strings. Therefore, there's no debate to be won here. :-)
Of course isset has a valid place - array_key_exists cannot replicate
what it does (it doesn't know about values), so they can play
together nicely - for example I'd consider this pretty robust:
if (isset($_SESSION) and is_array($_SESSION) and array_key_exists
('myvar', $_SESSION)) ...
If you get past that you can be absolutely certain that $_SESSION
['myvar'] exists, regardless of its value, and there is no
opportunity to trigger an error, whereas if you said:
if (isset($_SESSION) and is_array($_SESSION) and isset($_SESSION
['myvar'])) ...
you could still be wrong. The merest possibility of being wrong is a
bad thing in code. Why not use marginally different syntax and be
absolutely sure?
Yesterday I encountered an error in a large commercial php script and
it turned out that it was looking in $_SERVER['SERVER_NAME'] which
was there but set to NULL for some reason, and their test with isset
was failing. So it's not just academic and I'm not making it up -
this problem does happen for real.
All this over such a little thing - imagine if we had a whole
language to worry about! Oh wait...

I classify using isset for checking for the existence of array keys
to be a bad habit as in some common cases it will not work as you
expect, for example:
input type=checkbox name=checkbox_name /
(note it has no value attribute) If it's checked, you would get the
equivalent URL of ...?checkbox_name=, so $_REQUEST['checkbox_name']
exists, but may contain NULL, and isset would return false even
though it's there. A completely reliable check that will never
generate any warnings is:
array_key_exists('checkbox_name', $_REQUEST).
If you have several checkboxes in an array (using names like
name=checkbox_name[option1]), you would say:
if (array_key_exists('checkbox_name', $_REQUEST) and is_array
($_REQUEST['checkbox_name'])) {
if (array_key_exists('option1', $_REQUEST['checkbox_name'])) {
echo you selected option 1\n;
}
if (array_key_exists('option2', $_REQUEST['checkbox_name'])) {
echo you selected option 2\n;
}
//etc...
}

PHP doesn't now that it's PHP - it just treats it as text. You can

Eval is usually worth avoiding, but it will do what you ask.
Your display function could be improved:
function display()
{
$file = basename($_SERVER['PHP_SELF']);
require 'connect.inc';
$sql = SELECT HTML FROM `$db`.`$table_editor` WHERE `Filename`
LIKE '.addslashes($file).' LIMIT 1;;
if ($myquery = mysql_query($sql) and mysql_num_rows($myquery) 0) {
$mydata = mysql_fetch_array($myquery, MYSQL_NUM);
return $mydata[0];
}
return false;
}
Then call it:
if ($contents = display())
eval($contents);
This should be faster and safer than your original code.

It was simpler to use trim than to make the pattern skip it. Did you actually try it? On the other hand, I think we have to place a caret after the first slash. Only if you insist that your string must start with a word - putting a ^ at the start would make it omit the first word if there was a space in front if it. Instead of preg_match(), I had to type preg_replace(): err. I think you missed the point here. You don't need all that messy substr stuff at all. The preg_match already did it.

[PHP] Sessions and register_long_arrays
Strange behaviour that's taken me ages to track down. I have the situation where I can create a session, but any changes to it are not saved. session_write_close() didn't help. Eventually I tracked it down: if you have register_long_arrays disabled (as is the default in PHP5), this can happen. Enabling it fixed the problem. A very simple test case didn't show this problem, so I guess something in my sessions has a dependency on HTTP_GET_VARS or similar, though these old-style vars do not appear anywhere in my code... Some of the libraries I'm using may use them (for example Smarty, though I have the request_use_auto_globals option enabled for that which should stop it using them), but nothing to do with them is stored in the session. If I look at a session file, it's all just scalars and arrays, no complex types at all, but changing an item in $_SESSION simply does not get saved back to the session file if register_long_arrays is enabled. Anyone else seen this? Any idea why it might be happening?

[PHP] SOAP WSDL location
This is a minor thing that's been troubling me, making it difficult to deploy a salesforce.com SOAP client across multiple projects. Salesforce is a particular interest because its WSDL files are NOT available directly online - you have to download and save local copies manually. When constructing a SOAPClient object, the WSDL parameter provided is treated like a URL (because it will usually BE a URL). For 'local' URLs, it searches the current directory, including any relative path that it uses. However, because it is fundamentally a URL and not a file request like an include, it does not search the include path. The net result of this is that I'm having to copy my WSDL files into every place that my class library is called from because the URL resolution will only ever look in the calling directory and not in the include path that allowed it to find my classes. An alternative would be to allow providing the WSDL as a literal string, probably read using file_get_contents() which does support using the include path. A worse solution is to provide the WSDL contents as the response to a separate HTTP call (i.e. act like the WSDL is online after all). This would work, but it's way less efficient. I can't use an absolute path as it's deployed in multiple configurations on multiple servers, and config is bad enough already. Now before I report this as a bug/feature request, does anyone have any better ideas?

can work around it two ways; by changing the original declaration
(which just seems wrong - it's already in the global scope at this
point):
global $a;
$a = 1;
or by requiring the inc file inside each function of b (much less
efficient):
class b {
function test() {
require 'a.inc.php';
global $a;
echo $a;
}
}
Is this just how it is, or am I doing something wrong?

[PHP] __sleep, __wakeup and persistent connections
I'm sorting out some code to handle session object storage,
particularly where the objects contain DB connections. I've found
lots of articles that go on about how __sleep should clean up db
stuff, close connections etc and how __wakeup should reconnect, but
weirdly enough I've not found a single concrete example of doing this!
It's also not quite clear how this behaviour interacts with
persistent connections. For example, If I do this:
class foo {
protected $db;
public function __construct() {
$this-db = mysql_pconnect();
}
protected function __wakeup() {
$this-db = mysql_pconnect();
}
protected function __sleep() {
mysql_close($this-db);
$this-db = NULL;
return array();
}
}
given that the connection is persistent, and may thus be used by
other scripts, is calling mysql_close a particularly bad idea? Should
I just not bother closing the connection, letting PHP deal with it -
the object will not attempt to re-use the stale connection because it
will get a new instance courtesy of __wakeup when unserialized.
I'm also unclear about how __sleep acts in subclasses - it seems that
as soon as I have a __sleep function in a base class, I don't have
any choice but to implement __sleep functions in every subclass of
it, even if I don't want them to do anything that would not be done
if __sleep were not defined. in the exampel, the base class has no
properties to save, so it returns an empty array from __sleep, but
that's unlikely to be useful for a subclass that does have properties
(and serializing an object without any properties is pointless!).
Ideas?

I have lots of places where I used to do this. Since MySQL 4.1 I've
changed it to something like:
INSERT INTO mytable SET id = 123, bla = '$x' ON DUPLICATE KEY UPDATE

This saves you a query, and makes it easier to isolate the insert/

Java can go to the other extreme, where every simple type is an object, and hence it's easy (if not mandatory) to specify types like this. You would never be able to say 'print 2 + 2' in Java and expect to get 4. This looseness is very much part of what makes PHP so easy to get into - if you really want these kind of features, you can just use Java instead! Another point is that exception handling (another PHP5 feature) is next to useless without type hinting, so they HAD to implement it for objects so that catch clauses could work properly.

month and this year. How can i do that? I mean how can i found the

If you are storing it as a DateTime field, MySQL has loads of date
related functions for doing this, and it's more efficient to do it
using MySQL's functions that the equivalent in PHP. Take a look here:
http://dev.mysql.com/doc/mysql/en/date-and-time-types.html and http://
dev.mysql.com/doc/mysql/en/date-and-time-functions.html
You can do the calculations in PHP. For example, to find the first
day of this month as a timestamp:
$first = strtotime(date('Y-m-01'));
strtotime has some wonderful functionality - you can ask for dates
like 'next week' 'last year' 'yesterday -1 week'.
To format a timestamp into a MySQL-compatible DateTime string, use:
$datetime = date('Y-m-d h:i:s', $timestamp);

It's really just one big page, so if the user has JS turned off, they will get one big form with no client-side validation, but it will still work. It's a really elegant way of working. It doesn't require any server interaction between pages - nothing is submitted until the form is complete.

[PHP] Class constants
I'm not sure if this is a bug or a feature, but it seems you can't
use class constants to set default values for class properties. You
can, however, use them for default values for method params, e.g.:
class foo {}
const BAR = 100;
private $thing = self::BAR;
function wibble($a = self::BAR) {
echo $a;
}
}
In this case $this-thing will be undefined, but wibble() will get
the correct default value for $a.

ADOdb has a really nice session manager: http://phplens.com/lens/adodb/docs- session.htm Database-backed sessions are particularly useful if you have multiple redundant web servers as successive hits within a session may go to different servers, so file- or memory-based sessions are not much use.

[PHP] Calling methods in returned SOAP objects
I'm successfully calling SOAP functions via a WSDL interface using
PHP5, but sometimes the functions return things that are complex
objects with methods as well as attributes. For example, the
interface I'm using has a query function which returns an array, but
it also has a function called IsDone() which can be called to find
out if this is the last page of results (it returns records in batches).
It goes like this:
?php
require_once 'MyClient.class.php';
$mc = new MyClient();
$mc-dologin('id', 'pass');
try {
$res = $mc-query(array('queryString' = 'select Field from
Table'));
$alldone = $res-isDone();
} catch (SoapFault $f) {
print 'Caught Exception: '. $f-faultstring. \n;
var_dump($mc);
}
?
You can see that $res is the result returned from the query, and it
is presented as a stdClass object with results stored in an array
property. However, when I try to call $res-IsDone(), it fails to work:
PHP Fatal error: Call to undefined method stdClass::isDone()
I have some example code in Java for the same WSDL that makes it look
very simple:
...
queryResult = binding.query(select Field from Table);
if (queryResult.isDone()) {
...
How on earth do I do that in PHP? I don't think that creating PHP
classes and using classmap will help (it just moves the problem), at
least partly because this is a dynamic WSDL that is subject to change.

[PHP] iconv trouble on OS X
I wrote this question then found out where the problem was, so this
is just for the archives...
==
I've compiled PHP 5.0.4 successfully on OS X 10.4.2, but I'm getting
a weird problem with iconv. I specified it in my configure line:
--with-iconv
and it seems to pick it up ok while configuring:
checking for iconv support... yes
checking for libiconv in -liconv... yes
checking if iconv is Konstantin Chuguev's... no
checking if iconv supports errno... yes
It builds OK too. php thinks that the iconv extension is there:
php -m|grep iconv
iconv
The entry in phpinfo() is rather suspicious:
iconv support = enabled
iconv implementation = unknown
iconv library version = unknown
Then in one script I get:
Fatal error: Call to undefined function iconv()
and function_exists('iconv') returns false.
I've also tried specifying --with-iconv=/sw (i.e. using
libiconv-1.9.2-11 from fink), but I get the same results.
The solution lies in the user notes for iconv() where someone mentions:
elk at NOSPAMmodel-fx dot com
26-Jul-2002 04:07
If you use the libiconv library instead of the libc's iconv support,
don't forget to use libiconv() instead of iconv()
And it really is as simple as that - just substitute libiconv() for
iconv() - it seems that libiconv is the default on OS X. I think this
is a terrible implementation (clearly PHP itself is confused by it, 3
years on from this note) and I've no idea why it was done that way,
but now at least someone can find out easily.

[PHP] Overriding __soapCall
I'm working on a soap client in PHP5, which I'm building by
subclassing the built-in SoapClient class. However, it seems my
overridden __soapCall method is never being called. My class looks
something like this:
class myClient extends SoapClient {
public function __construct($wsdl = 'http://www.example.com/
my.wsdl', $options = NULL) {
if (!is_array($options))
$options = array('soap_version' = SOAP_1_1, 'trace' =
true, 'exceptions' = true);
parent::__construct($wsdl, $options);
}
public function __soapCall($function_name, $arguments = array(),
$options = array(), $input_headers = NULL, $output_headers = array()) {
echo doing __soapCall\n;
return parent::__soapCall($function_name, $arguments,
$options, $input_headers, $output_headers);
}
}
The constructor works fine. As you can see __soapCall does nothing
but pass through the call to the parent, but it's just not being
called. I've found various references to overriding the __call
function (which is now completely obsolete as it clashes with a magic
method) for the same kind of reason that I need to. So, it seems as
if __soapCall is NOT called internally when calling a WSDL function,
so if my client has a login function:
$sc = new myClient();
$sc-login(array('username' = 'abc', 'password' = 'xyz'));
but this does not seem to go via the internal __soapCall function,
thus denying me the ability to tweak the request on its way through.
If I call it manually (i.e. non-WSDL way), something like:
$sc-__soapCall('login', array('username' = 'abc', 'password' =
'xyz'));
then it works, but in that simple gesture I've lost most of the WSDL
advantage.
What am I supposed to do?

Answering my own question - __soapCall is not called internally, but
you can force it by using __call (that is the magic method, not the
obsolete __call function in SoapClient) by adding this function to
the class:
function __call($function, $args) {
return $this-__soapCall($function, $args, null);
}
This means that I can finally get to pass stuff though my own
__soapCall method, though I have the feeling that it may prevent me
doing other stuff later on (I'm not normally relying on __call
functionality).
Phew.

PHP's build system is completely independent of XCode.

So while you don't need XCode to compile, you do need the developer tools, which is almost synonymous with XCode. Of course I have the developer tools installed - I wouldn't even be able to attempt a compile without them. XCode is an IDE - it provides project management and a nice GUI for lower level tools, however, it is squarely targeted at development of OS X applications that are set up as XCode projects, which does not include PHP. Bear in mind that almost none of the thousands of open source projects available via sources like fink have anything to do with XCode - they're all designed for a standard unix-style build system using the tools I mentioned. Doesn't 10.4 ship with gcc 4? I know I read about some bugs and problem with gcc 4, some specifically related to PPC chips. Do you know if you are compiling using 3.3 or 4.0? I'm using the standard system gcc 4.0.0, but this is a problem with the parameters (defined in the PHP configure script) passed to ld, so strictly speaking this is a linking rather than a compiling problem (i.e. the problem occurs after gcc has finished successfully). It seems that the OS X ld has different options to the GNU or BSD implementations, so I guess I'm really after someone that knows ld well enough.

It wouldn't solve everything, but it would help. It solves the case where you have a class library that's quite heavily interconnected, and member functions instantiate other classes in that library (a common arrangement in my experience). By having an __autoload method, you get to at least partly avoid global handler clashes by having one that is specific to that library (it would work well in PEAR). If it is in a base class, then you are safe in the knowledge that any class can find any other in the same library, without tripping over anyone else's arrangements. You would still have to deal with the problem of finding the first class (which a global handler may help, subject to the issues that you've already raised), but once that's done, the problem is over. I don't see why they named it __autoload - the __ prefix is usually reserved for special purpose methods, not global functions. Just plain 'autoload' in a global context is not really anything wildly different in style to say ini_set or error_reporting.

Huh? Writing a 1-line function in a base class means that I would never have to write another require anywhere in my library (other to include the base class of course, which could conceivably be picked up by a global autoload anyway). Each of my 50-odd classes probably talks to 5 other classes in the library, giving a net saving of 250 lines. How is that bad? (I am talking hypothetically anyway as we don't have autoload methods at present). This thread is meant to be about how to improve automatic include file location - saying not to try to do it at all is not very helpful.

I can surf to http://example.com/admin.inc and who knows what will happen if that PHP code in there gets executed without all the code you expected to be executed before that code? There is one simple habit that can mitigate this issue, and it's one I see very often: make your .inc.php and .class.php files do nothing. If you .inc files contain only function and constant definitions, and your .class files contain only class definitions, then nothing will happen when you run them - a bunch of functions or a class will get defined, but if nothing is run, they will just be forgotten. This route has a major advantage when it comes to deployment - you can just stick all your files in one place, and it will work without risk. Another simple approach is to put all your included files in a directory that contains a .htaccess file to prevent direct access to them. They can still be included from your PHP scripts.

Now my question, is it possible to skip that require/ include part? In
Java you don't need that, as class and file names are identical.
PHP doesn't have this luxury - people can call files whatever they
like. However, PHP5 does have a nice feature to deal with this. In
your class1 class, create a function called __autoload like this:
function __autoload($class_name) {
require_once $class_name . '.php';
}
In this case when you ask for a new class2 and you've not required it
before, it will automatically call __autoload with $class_name set to
'Class2', which then requires the class file according to the pattern
used in the function, in this case 'Class2.php'. Note that while PHP
is not case sensitive to class names, the file system you're on
probably is, so keep your case consistent throughout.

One way that would work for me (and initially it's how I assumed it worked) is for __autoload to be a standard class method like __construct, so that a class would attempt to run its own autoloader before breaking out to the global function namespace.
