Tested on Apache 2.2 with PHP 5.1.
If you really want to get the default Apache error handler to appear
then either readfile() it or redirect to it.

I hope I can explain my problem/questions clearly. Thanks in advance:
Scenario:
I'm working on a Log class that my app will use to write
debug/error/etc messages to a file. I've created it so that as the
application logs messages, these messages are queued within a property
of the Log class, and only written to the file when the Log object is
being destroyed.
I wanted to place all of the file writing to within __destruct() to
avoid holding a connection to the log file throughout the life of the
app's state.
Problem:
Everything works fine, UNLESS I move the fopen('log-file-name') call
to within the __destruct() method. If I open a handle to the log file
within the __construct() method, or any other class method, it works
fine. But I receive a permissions error if it's called within
__destruct().
Error reads: Warning: fopen(20060331.txt) [function.fopen]: failed to
open stream: Permission denied in ...
Caveat:
I have found that if I explicitly destroy an instance of Log with
unset(), then fopen() will work even when it is within the
__destruct() method. However I don't like that solution...and
besides, I'm planning on creating an instance of the Log class from
within the __construct() of my Controller class, and trying to
explicitly destroy Log with an implicit __destruct() of my Controller
doesn't work either. :P
Question(s):
1. Could anyone explain a bit more as to why fopen() won't work within
an implicit call to __destruct()? What permissions has my app lost at
this point?
2. Am I at least correct in my intention to limit the duration that
the handle to the log file is open?
3. Is there workaround to this little conundrum that anyone can think of?
Code:
Here's a simplified version of the code (it's complete, feel free to
copy-and-paste-and-play). I've commented the fopen code block in
question.
[code]
// Create an instance of Log
$log = new Log();
// Attempt to log a message

you can't use overloading directly on items of an overloaded array e.g:
echo $tc-arr['a']
this is triggers a call to __get() with the $key parameter set to
something like
(I'm guessing) arr['a']
No, I'm pretty sure (too lazy and tired right now to test...) that if
you guess wrong :-) .. I couldn't resist testing it:
php -r '
class T { private $var = array();
function __set($k, $v) { $this-var[$k] = $v; }
function __get($k) { var_dump($k); }
}
$t = new T;
$t-arr = array();
$t-arr[a] = 1;
echo OUTPUT: \n; var_dump($t-arr); var_dump($t-arr[a]);
var_dump($t);
'
That's weird, because I did get around to testing it before I saw your
mail, and in my test it works as *I* expect (PHP 5.1.2)...
a couple of things: I tested on 5.0.4 yesterday (should have mentioned that)
- just tried on 5.1.1 and the behaviour there _seems_ to agree
with your premise ... but not completely; the outcome is expected but the
code doesn't do what I believe it should be doing with regard to
guarding against arbitrary crap into an object via __set() - I assume people
use __set() to protect variables, in the same way as 'normal' setters
are often used. I modified you test code a little - notice how __set()
is only called once (the second 'set' is actually a 'get'!):
?php
class T {
private $array = array();
public function __get( $key ) {
echo Getting $key\n;
return $this-array[$key];
}
public function __set( $key, $value ) {
echo Setting $key\n;
$this-array[$key] = $value;
}
}
$t = new T;
$t-insideArray = array();
$t-insideArray[test] = testing!;
var_dump( $t );
?
OUTPUT:
Setting insideArray
Getting insideArray
object(T)#1 (1) {
[array:private]=
array(1) {
[insideArray]=
array(1) {
[test]=
string(8) testing!
}
}
I personally feel that the fact that $t-array['insideArray']['test'] is
being set (why does __set() seem to return a reference) is unwanted ...
it circumvents any variable checking logic I might have in __set()
how do like them apples? ;-)

Re: [PHP] HTTP status code
No,
I'm creating remote service and it's returning codes according to passed
parameters. I only wanted to test it using browsers...
I do not care about the output actually, but the status code
B.
It seems to me, that this is more html-related. Maybe the tags in the
html-document screws it up regarding to the use of html. IE is more
insensitive regarding correct typing of html-tags.

header(Status: 404 Not Found);
Why do you have ' on the first line and on the second?

Re: [PHP] Failing to write to a file when a class is being implicitly destroyed
basically when php shutsdown at some stage stuff like file manipulation,
db access will have been torn down - the implicit object destruction (and
therefore the call to __destruct() happens to late in the shutdown process
to be of any use ... there is a big chicken and egg problem there (search the
archives of the php-internal mailing list should reveal lots of discussion
surround this topic)

that's probably due to references still existing (according to the engine)
to you Log object.
Question(s):
1. Could anyone explain a bit more as to why fopen() won't work within
an implicit call to __destruct()? What permissions has my app lost at
this point?
it's seems rather odd that the error would return a permission problem.
I don't get that at all.
2. Am I at least correct in my intention to limit the duration that
the handle to the log file is open?
it's a good idea yes - any system will have some kind of max as to the
number of open files that are allowed/capable.
3. Is there workaround to this little conundrum that anyone can think of?
explicit destruction. may try working with register_shutdown_function()
- the ctor of your log object could register a 'flsuh' method to be run at
shutdown (which may well be at an early enough stage that opening/writing
files is still possible)
personally I avoid __destruct() - it gives me headaches and never seems
capable of doing what I think it should be able to!
Code:
Here's a simplified version of the code (it's complete, feel free to
copy-and-paste-and-play). I've commented the fopen code block in

if (fwrite(self::$handle, self::$message) ===

the 'die' and 'exit' in the code directly above is probably a really bad idea!
and given that the code is currently living in a dtor rather unnecessary

That's weird, because I did get around to testing it before I saw your

My comments earlier were based on the fact that it would not be good
to limit what can be put in an object through __get and __set
effectively to scalar variables, and I would expect the engine
developers to realise that. I think they have (unless I've done
something stupid in my test code...):
Code:
?php
class T {
private $array = array();
public function __get( $key ) {
return $this-array[$key];
}
public function __set( $key, $value ) {
$this-array[$key] = $value;
}
}
$t = new T;
$t-insideArray = array();
$t-insideArray['test'] = 'testing!';
var_dump( $t );
?
Output:
object(T)#1 (1) {
[array:private]=
array(1) {
[insideArray]=
array(1) {
[test]=
string(8) testing!
}
}
}
Dont know if you guys see the MAJOR difference between your code, so I
will point it out.
Jasper did this
function __get($k) {
var_dump($k);
}
Jochem did this
public function __get( $key ) {
return $this-array[$key];
}
First off, the required public before the function call was not
included, secondly, Jasper is var_dumping the key of the array, not the
array it self.
Hope this helps
And yes, it should work the way Jochem was expecting. At least that is
what the manual says, and my testing says.
But you have to make sure you include all the needed parts to make it
work correctly.
Thanks Jim

[PHP] Going loopy with arrays.....
Howdy all! Here is hoping that Friday is just another day in paradise for everyone. I have an array, a multi-dimensional array.

You could use variable variables with an array, like this:

array('readingGoalsEnjoymentLabelClass','readingGoalsInformationLabelClass',
'readingGoalsAlphabeticLabelClass','readingGoalsPrintLabelClass',
'readingGoalsPhonologicalLabelClass','readingGoalsPhoneticLabelClass',

'readingGoalsInstructionsLabelClass','readingGoalsCriticalLabelClass',
'readingGoalsCommunicateLabelClass');
foreach ($arr as $var) {

}
/* This is to check if it was done correctly. */
foreach ($arr as $var) {
echo $var = ${$var}\n;

Re: [PHP] XML-RPC or SOAP

Okay, that is cool too, but it still lacks one key ingredient, I need to know
which 'H' each lat an lon belongs to.
Here is the pseudo-code for what I am attempting, I fear I may not have
explained myself clearly enough earlier;
Loop
Get the current H
While current H
output the points of current H
end while
next H
End loop
It is gotten to the point where I am tempted to put each H in its own file,
open it, do the stuff, close it, go to the next file as it might have been
quicker but I so wanted to do this with the array. The complication is that
when the file is sent the H's are not in order, so they have to be grouped
together (with changing their order in the file) so that the output occurs
logically.
Thanks everyone!

RE: [PHP] Going loopy with arrays.....
Yeah, that foreach is outright printing the arrays (foreach $parent... print
$parent?)
I'm guessing you wouldn't ask this, Jay, unless there was an issue with not
knowing the depth of the data.
I saw something once with doing recursive function calls to dig down into an
array or something. So it'd be something like this:
function finddata($arr) {
foreach ($arr as $key = $value) {
if (substr($key, 0, 1) == H) {
echo bi$key/i/bbr\n;
foreach ($value as $subkey = $subvalue) {
echo [$subkey] lat: . $subvalue[lat] . long: .
$subvalue[lon] . br\n;
}
} else {
finddata($value);
}
}
}
finddata($mainarray);
Something like that.. my brain's working at 50% today as it is, but maybe this
gives you a nudge in the right direction.

If I can have the department upload the file (I know, I could parse the uploaded file etc. etc...but this needs to be quick...or needed to be) or just save it to the proper location then I wouldn't have to worry about the updates, unless something failed. I have set a couple of rules that the file must follow, but they can do anything else that they want to (and they will) with the file.

Public is not required. I always put it regardless, but if you leave it
off then PHP defaults to public for compatibility reasons.
Jochem's code, which behaves incorrectly, does var_dump. Mine just
returns the array key as you would expect. That's why Jochem's doesn't
behave correctly with arrays.

Re: [PHP] Overloading Limitation- Can Someone Confirm?
could you both take a look at this (I posted it already btw) - notice that
the second 'set' action ($t-insideArray[test] = testing!;) is not going
via __set() at all, it uses __get() BUT/AND then an item is set in the returned
array ... and also in the [sub] array stored inside the object (even though
nothing is being returned by reference):
(I feel that this is not right somehow!)
?php
class T {
private $array = array();
public function __get( $key ) {
echo Getting $key\n;
return $this-array[$key];
}
public function __set( $key, $value ) {
echo Setting $key\n;
$this-array[$key] = $value;
}
}
$t = new T;
$t-insideArray = array();
$t-insideArray[test] = testing!;
var_dump( $t );
?
OUTPUT:
Setting insideArray
Getting insideArray
object(T)#1 (1) {

You need to set your variable ('missing') before using it.

That's terrible overkill. Regex is not designed for simple substring
matching. You want:
if( strpos( $string, '../' ) !== false )
echo 'string has ../';
By the way, your problem is that . is a special character in regular
expressions, so needs escaping with a backslash, and you have used / as
your delimiter but also use it inside the pattern. You should use a
different delimiter (also, there's no point in using the 'i'
case-insensitive flag, since there's no characters in your pattern).
The strpos() solution above is much better and faster in this case, though.

Can't get it to work can anyone help?
Since / is your delimiter you need to escape it.
Also '.' means anything so you need to escape that as well.
if (preg_match('/\.\.\//', $string)) ...
What are you trying to achieve? There may be a better way than using a
regular expression.

Re: [PHP] Overloading Limitation- Can Someone Confirm?
Chr is wrote:
You're right, it's not going through the __Set() method a second time.
If you REALLY want to get confused by overloading behavior try the
following code using your T class:
$t = new T;
$t-insideArray = array('a' = 'A', 'b' = 'B', 'c' = 'C');
foreach ($t-insideArray as $k = $v) {
$t-insideArray[$k] = null;
}
if (count($t-insideArray) 0) {
foreach ($t-insideArray as $k = $v) {
echo $v;
}
}
var_dump($t);
Why does count() return 0?
Why has $t-insideArray become NULL instead of an empty array?
I can't tell you because I don't have access to a 5.1.2 CLI at the moment.
I can tell you that this leads to a SegFault on 5.0.4, here is the output:
Setting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Segmentation fault
and on 5.1.1 it's not much better, the output is:
Setting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
Getting insideArray
FATAL: emalloc(): Unable to allocate 1916888421 bytes

could you both take a look at this (I posted it already btw) - notice
that
the second 'set' action ($t-insideArray[test] = testing!;) is

via __set() at all, it uses __get() BUT/AND then an item is set in
the returned

nothing is being returned by reference):

Dont know if you guys see the MAJOR difference between your code,
so I will point it out.
Jasper did this
function __get($k) {
var_dump($k);
}
Uhm, no I didn't. Jochem did :)
Jochem did this
public function __get( $key ) {
return $this-array[$key];
}
No, I did that.
First off, the required public before the function call was not
included, secondly, Jasper is var_dumping the key of the array, not
the array it self.
Public is not required. I always put it regardless, but if you leave
it off then PHP defaults to public for compatibility reasons.
Jochem's code, which behaves incorrectly, does var_dump. Mine just
returns the array key as you would expect. That's why Jochem's
doesn't behave correctly with arrays.
