Re: [PHP] Appending into associative arrays
$fmtime = filemtime($d); if (!array_key_exists($fm,$dir)) $dir[$fm] = array(); $dir[$fm][] = $d; This would give you an array indexed by filetime containing arrays of filenames. You may try and see if the last line is enough on its own, but I believe it once happened to me that it failed to create a two levels deep array of arrays in just one shot, that's why the second line. Alternatively you could use the filename as key of the second array and store in it any information as data, for whatever you might need: $dir[$fm][$d] = some data related to $d.

function recurseDir ($base, $accending = true, $dirs = array()) {

if (($dir != '..') and ($dir != '.')) {
$d = $base.'/'.$dir;

}
}
closedir ($handle);

and then you can call array_keys on the result of the whole recursion

Uhm, it's not even possible when you don't know the keys i believe.
after 2 hours of testing and research I realized this too, but want
to be sure. :-(
If you really *must* do this yourself (but others have pointed out the folly of
it), this would do it:
function value2var($array)
{
foreach ($array as $key = $value)
{
$GLOBALS['$key'] = $value;
}
}
... or, alternatively, rather than defining you own function, use extract()
(http://php.net/extract) with one of the overwrite safety options to avoid
blobbing existing variables.
Personally, I'd never do this in any form -- if I do it at all, I extract
specific indices of the array with code like:
foreach (array('name', 'address', 'email', 'setting1', 'setting2') as $key):
$GLOBALS[$key] = $array[$key];
endforeach;
... making certain, of course, that those values get properly validated
elsewhere.

It would be much cleaner to not pass $dirs into the function and
use array_merge() on the returned array instead, additionally
having to call array_keys() on the call to recurseDir() seems rather
lame (too much of wtf factor imho).
function recurseDir ($base, $ascending = true, $self_called = false) {
$handle = opendir($base);
$dirs = array();
while ($dir = readdir($handle)) {
if (($dir != ..) and ($dir != .)) {
$d = $base./.$dir;
if (is_dir ($d)) {
$dirs[$d] = filemtime($d);
$dirs = array_merge($dirs, recurseDir($d, $ascending, true));
}
}
}
closedir ($handle);
if ($self_called) {
return $dirs;
} else {
asort ($dirs);
return array_keys($ascending ? $dirs : array_reverse($dirs));
}
}
not exactly pretty, what with the use of $self_called - but at least it keeps
all the crap inside the function.

[PHP] Problems when trying to use ibm_db2 extension
Hi all,
I've been banging my head into the wall cause I can't get ibm_db2
extension working with Apache 2.0.59 and PHP 5.2.1 (as apache module).
(Operating system is winxp pro SP2)
For some reason, this code is working on command line but not when
placed to htdocs folder:
?php
if(function_exists('db2_connect')) {
echo 'Function db2_connect() exists';
} else {
echo 'Unknown function db2_connect()';
exit;
}
echo \nTrying to connect DB2 database..\n;
$database = 'services';
$user = 'db2admin';
$password = 'xxx';
$hostname = '127.0.0.1';
$port = 5;
$conn_string = DRIVER={IBM DB2 ODBC DRIVER};DATABASE=$database; .
HOSTNAME=$hostname;PORT=$port;PROTOCOL=TCPIP;UID=$user;PWD=$password;;
$conn = db2_connect($conn_string, '', '');
if ($conn) {
echo OK: Connection established\n;
db2_close($conn);
} else {
echo ERROR: Connection failed\n;
}
?
Command line output:
C:\php c:\db2_test.php
Function db2_connect() exists
Trying to connect DB2 database..
OK: Connection established
Web output:
Unknown function db2_connect()
Some extra output:
Fatal error: Call to undefined function db2_connect() in
F:\www\services.itella.net\app\webroot\index.php on line 57
Also, phpinfo() won't say nothing that module ibm_db2 is in use
More info:
php_ibm_db2.dll file is in folder C:/php-5.2.1/ext
php.ini:
extension_dir = C:/php-5.2.1/ext
extension=php_ibm_db2.dll
httpd.conf:
AddType application/x-httpd-php .php
LoadModule php5_module C:/php-5.2.1/php5apache2.dll
PHPIniDir C:/php-5.2.1/
Can someone point out the right direction for me?

Uhm, it's not even possible when you don't know the keys i believe.
after 2 hours of testing and research I realized this too, but want
to be sure. :-(
If you really *must* do this yourself (but others have pointed out the folly of
it), this would do it:
function value2var($array)
{
foreach ($array as $key = $value)
{
$GLOBALS['$key'] = $value;
}
}
What's the sense in above function? you're putting the variables from
1 array in another...
you could use array_merge for this.
But even then it's quite useless...
... or, alternatively, rather than defining you own function, use extract()
(http://php.net/extract) with one of the overwrite safety options to avoid
blobbing existing variables.
That's a better idea. :)
Personally, I'd never do this in any form -- if I do it at all, I extract
specific indices of the array with code like:
foreach (array('name', 'address', 'email', 'setting1', 'setting2') as $key):
$GLOBALS[$key] = $array[$key];
endforeach;
endforeach? never heard of that statement before, does it really exist in PHP?
... making certain, of course, that those values get properly validated
elsewhere.
Cheers!
Mike
Sure, you should always validate your variables, but i would recommend
to only get the variables from $_GET/$_POST that you actually gonna
need, and not just everything.

You COULD always use empty() prefixed with an @ to quiet the E_NOTICE,
but, me, I could/would possibly miss that when scanning the code.
I would however see the isset() !empty() bit of code.
And the amount of time that you save by not using isset(), well, lets just say that if it affected
the time of your apps performance, I think you have other things to worry about first.
Just for example. The current project that just took over has about 60,000 lines of code. Doing a
quick grep -ri 'isset' * on the dir returns about 475 instances of that function call. Many of
which I have added to the system to get rid of E_NOTICE warnings, for the simple fact that I wanted
to set error reporting to E_ALL. Bad mistake, over half the scripts fire off warnings left and
right, because all he was doing for checking was !empty() if ( $var ) {} or if ( $var != '' ) {}
calls all over the place.
There are two ways that I have found to get rid of the notices.
Example #1
if ( isset($_GET['something']) !empty($_GET['something']) ) {
// do something here with $_GET['something']
}
Example #2
if ( @!empty($_GET['something']) ) {
// do something here with $_GET['something']
}
Other suggestions would be gladly accepted.

empty() does NOT produce an E_NOTICE if the variable is not set.
That's one of the things it considers as empty.
And why I always do !empty($foo) then check for a value such as (!

No you won't. The empty function does not raise a notice if its argument

empty() is the opposite of (boolean) var, except that no warning is

I think you should change above line to :

yup! it's print error. I meant $array.
{
${$key} = $value;
echo ($print ==1) ? $key.': '.$value.'br';
// to test
results and seeing array variables and values
}
}
value2var($_POST, 1);
but, I don't know how to get info from function back to
script?!?!? :-(
Uhm, it's not even possible when you don't know the
keys i believe.
after 2 hours of testing and research I realized this too, but
want to be sure. :-(
If you really *must* do this yourself (but others have
pointed out the folly of it), this would do it:
function value2var($array)
{
foreach ($array as $key = $value)
{
$GLOBALS['$key'] = $value;
}
}
What's the sense in above function? you're putting the variables from
1 array in another... you could use array_merge for this.
But even then it's quite useless...
No, not just another array (although I agree about the function being pretty useless!)
-- $GLOBALS is a superglobal array that contains a reference to every variable defined in the
global scope, so that accessing $GLOBALS['var'] from anywhere is the same as accessing $var in the
global scope. It's a way of referencing global variables without having to use a global
$var statement.
but $_GET and $_POST are also global variables, so you transfer
variables from one global variable to another :)
I was simply pointing out how you can to get info from function back to script
when you don't know the keys, which you'd just said you believed was impossible! ;) ;)
You can also return an array ;)
I mean to say returning multiple variables (not arrays)
Having done which, I proceeded to point out that:
... or, alternatively, rather than defining you own
function, use extract() (http://php.net/extract) with one of
the overwrite safety options to avoid blobbing existing variables.
That's a better idea. :)
... Precisely ;)
foreach (array('name', 'address', 'email', 'setting1', 'setting2')
as $key): $GLOBALS[$key] = $array[$key];
endforeach;
endforeach? never heard of that statement before, does it
really exist in PHP?
Of course -- would I give you non-working code? (Well, on purpose, anyway! ;)
See http://php.net/manual/en/control-structures.alternative-syntax.php
Cheers!
Mike
Never knew there was an alternative syntax... (in all these years...)
Of course you would (try to) give working code, but you could've be
confused by other programming languages :)

Interesting, have not looked at the empty() man page in a long time.
It use to through E_NOTICE warnings, as far back as I can remember back in
1999, and 2000
I wonder if they changed it, or the person that told me to do it that way was
mistaken.
my mistake.

RE: [PHP] Problems when trying to use ibm_db2 extension
My first guess would be to make sure that the version of PHP that you
are running from CLI is the same as the one running as an apache module,
and that they are configured the same. When running the CLI, do an
?php phpinfo(); ?
And compare the output with what you get from doing the same thing from
the web.

Subject: [PHP] Problems when trying to use ibm_db2 extension
Hi all,
I've been banging my head into the wall cause I can't get ibm_db2
extension working with Apache 2.0.59 and PHP 5.2.1 (as apache module).
(Operating system is winxp pro SP2)
For some reason, this code is working on command line but not when
placed to htdocs folder:
?php
if(function_exists('db2_connect')) {
echo 'Function db2_connect() exists';
} else {
echo 'Unknown function db2_connect()';
exit;
}
echo \nTrying to connect DB2 database..\n;
$database = 'services';
$user = 'db2admin';
$password = 'xxx';
$hostname = '127.0.0.1';
$port = 5;
$conn_string = DRIVER={IBM DB2 ODBC DRIVER};DATABASE=$database; .
HOSTNAME=$hostname;PORT=$port;PROTOCOL=TCPIP;UID=$user;PWD=$password;;
$conn = db2_connect($conn_string, '', '');
if ($conn) {
echo OK: Connection established\n;
db2_close($conn);
} else {
echo ERROR: Connection failed\n;
}
?
Command line output:
C:\php c:\db2_test.php
Function db2_connect() exists
Trying to connect DB2 database..
OK: Connection established
Web output:
Unknown function db2_connect()
Some extra output:
Fatal error: Call to undefined function db2_connect() in
F:\www\services.itella.net\app\webroot\index.php on line 57
Also, phpinfo() won't say nothing that module ibm_db2 is in use
More info:
php_ibm_db2.dll file is in folder C:/php-5.2.1/ext
php.ini:
extension_dir = C:/php-5.2.1/ext
extension=php_ibm_db2.dll
httpd.conf:
AddType application/x-httpd-php .php
LoadModule php5_module C:/php-5.2.1/php5apache2.dll
PHPIniDir C:/php-5.2.1/
Can someone point out the right direction for me?

$_POST['last_name'] = 'Doe';
$_POST['address1'] = '123 Someplace Dr.';
$_POST['something_else'] = 'Some Value';
$wanted = array('first_name', 'last_name', 'address1');

Lemme guess... You don't like empty() because it thinks null/0/'' is
empty? Or is there some other reason?
Agreed, it can be tricky if you just use it everywhere, but for most
things, especially replacing a
if (isset($foo) $foo != 0/null/''/array()) {}
with
if (!empty($foo))
makes my life a little easier. Especially checking for empty arrays
since foreach on an empty array will throw a notice or warning, I
forget which atm.
Of course if null/0/'' are considered valid values in your code then
you're pretty much stuck with isset() and checking for the value.
And doesn't it also consider 'null' (the string) as empty? Seems like
I've read folks complaining that returns from a database that are set
to null get missed also... but since I don't have any code that
considers null a useful value it's never been a problem for me.

well, as the OP said, he wants to know when the variable has a value other the

So, to check for that you have to do something like this right?
if ( $var != '' ) {}
if ( strlen($var) 0 ) {}
if ( !empty($var) ) {}
... a number of other ideas come to mind, but
none of them will work, because they will always product a E_NOTICE warning.
You COULD always use empty() prefixed with an @ to quiet the E_NOTICE,
Stut wouldn't do that... especially not after calling isset() a waste of
cycles. using the @ to suppress warnings/errors still invokes the error
system, and that includes any error handler you've custom hooked.
Maybe Stut just writes bad code ;) ;)
I'm thinking I just know some parts of the language better than you lot.
You guys really should try reading the manual before responding instead
of just assuming it's the way you think it is.
As far as my coding style goes, that's between me and my $DEITY, but let
it be noted that even my production servers run with error_reporting as
E_ALL (but logged to files and not displayed obviously). Knowing how
isset and empty work is essential to enabling my style of coding PHP,

Two files may have the same modification time.
You are storing only ONE file for any given timestamp.
You could do something like this:
foreach($files as $file){

You will then have an ARRAY for each timestamp with all the files that

That is VERY different from not being set at all.
If you do not want to allow the empty string as a valid input, that
should, imho, be handled by your data validation routines, which
happen after your business logic of doing whatever based on isset()
http://php.net/strlen is a good one for that.
In other words, use isset() to decide what the user is trying to do
first.
Then use data validation to decide if they have provided
valid/suitable input. If the input is egregious enough (i.e., no
normal human would ever generate that state) you can respond
differently with, say, die(hacker);

If I'm already certain that it's an array, I just use 'count' personally.
'empty' takes a mixed data type, and could return TRUE for, say, 'foo'
even though you are expecting an array there.
I think it's a better practice to use the right weapon and use
count() on an array to see if it's empty or not.

If I'm already certain that it's an array, I just use 'count' personally.
'empty' takes a mixed data type, and could return TRUE for, say, 'foo'
even though you are expecting an array there.
I think it's a better practice to use the right weapon and use
count() on an array to see if it's empty or not.
php -r 'var_dump(count(foo));'
outputs:
int(1)
so my strategy is usually
if (!empty($r) is_array($r)) {
// good to go.
}
if I know it's an array I'll definitely use empty() over count()
count() needs to actually count the items where as empty() can return false
as soon as it finds a singel element ... maybe I'm mistaken - if so please
put me right.

Richard: How secure is this: I can't answer that question definitely just looking from the outside in... A deadbolt may look secure from the outside, but if it's balsa-wood behind the locked door, that deadbolt ain't worth squat. :-) http://sperling.com/a/pw There are seven files there, namely: http://sperling.com/a/pw/.htaccess http://sperling.com/a/pw/a.php http://sperling.com/a/pw/b.php http://sperling.com/a/pw/auth.php http://sperling.com/a/pw/index.php http://sperling.com/a/pw/girl.gif-- not protected. http://sperling.com/a/pw/girl.jpg -- protected, but well worth the effort. Are any of these files accessible, even when you know the path? And by accessible I mean can you obtain any information that the files contain? index.php is also accessible, if I can guess the login, which I did on my first try... a.php is also then accessible. I can then visit b.php and auth.php, which do not seem to generate output. girl.jpg remains in accessible, however, afaict. For example, if I were to tell people to store their user id and password in a configuration php file with a known path, would it be safe? I realize that if the server is breached then nothing is safe, but barring that -- how safe would that be? Consider the following scenarios: SCENARIO #1 Your webhost is about to go out of business, and you tar up your site in a super big hurry, and slam it into a new server. Whew! You check it out, and it works, and you toddle off to bed exhausted. Turns out, though, that the .htaccess files didn't get into your tarball, because you forgot that you needed to add them explicitly. So a bunch of stuff in your webtree on your shiny new server is wide open. Yes, this has really happened. To me. Fortunately, I had other stuff in .htaccess that made it obvious that something was wrong, and the window of opportunity was short, but there it is. And it wasn't like the world was gonna end or anybody's money was at risk or even anything personal info, really. But still... SCENARIO #2 The server admin (possibly you, possibly not) upgrades Apache, and somehow manages to not install PHP. Or, perhaps, doesn't use the same extensions (.php3 anybody?) for PHP. Or, perhaps, messes up that line and forgets to add the .html you've grown accustomed to being passed through PHP. Any one of these can suddenly expose your password to the whole Internet. These are things that should not happen, but have happened, and will happen again, to somebody somewhere. If you put the stuff you want to keep private OUTSIDE the web-tree, and provide a PHP gate-keeper to get to it, you reduce your risk. It's a lot harder to screw up bad enough to configure Apache to start serving up files directly from a private directory. I won't say nobody has ever managed to do that. In fact, I'm sure somebody somewhere has managed it with a +FollowSymLinks and then putting a symlink in the web tree out to the private dir, because they didn't know how to work PHP's include_path... But it takes a lot more work to mess that up than a simple common typo. So it's not about whether I can get to the stuff NOW. It's about whether things could EASILY go wrong enough that I could get to the stuff tomorrow. Let's also consider the case of my visiting b.php and auth.php In this small tiny sample application, it's unlikely that either of those do anything interesting enough when I visit them out of sequence. However, in a LARGE application, if the user visits a .php file completely out of sequence from any QA process you have ever run, because they are surfing to random .php files to try and break your application, what happens? A: PHP code is executed completely out of context, in a manner you have never ever tested at all, much less subjected to any kind of formal QA process. In essence, the visitor is running code that you've never even tried, at least not in that particular environment. As code grows and accretes more and more cruft, and a large complex web application emerges, can you really guarantee that the user running some arbitrary chunk of PHP code out of sequence like that is never ever going to be a problem? Use PHP's include_path and get the include files OUT of your webtree. PS I'm assuming that you intended it to be easy to guess the login for the HTTP Basic Authentication... :-) PPS Nice photo! :-) -- Some people have a gift link here. Know what I want?

Tight coupling - inflexible code. This seems pretty ridiculous argument to me. You either have JSON isntalled, or you don't. If you have it, having it as an OOP thingie or as a function doesn't make any real difference if you know how to write decent code in the first place. It's not like it's any easier to swap out the current JSON package for a mythical new one. Global search and replace or writing a wrapper function or whatever is going to be equally easy. Any real pain will be in whether the substitute JSON actually outputs the same thing as the one you used before, not in the syntatic sugar/bloat of having: $json = new json(); $foo_json = $json-encode($foo); versus $foo_json = json_encode($foo); Getting all bent out of shape about OOP versus procedural just makes no sense to me, if one has competent programmers...

I've been accuse of that too, but what's your solution?
In the above example,
if (isset($_GET['something']) !empty($_GET['something'])) {
is the same as...
if (!empty($_GET['something'])) {
So, in that particular line of code the isset is a pointless waste of

these two lines are not the same infact, with the first, you will not

See I was just wondering, and that at times leads to late nights I used to read the images from two different files; one watermarked the image and one let it throught without any hazzle. Of course this kind of script was easy enought to get around the watermarking, witch I fixed with the http referer witch as follows IE don't send. I don't particulary like ppl who use IE (ups did I upset someone?) ;D. Using referer for anything other than logging it for analysis later is probably your first mistake... However I started compressing my scripts and putting them inside one file. And the status is so far: * Query for the image object. * Query for copyright check in case of watermarking. If no watermarking skip to echo * Read the object. * put object in a file outside webroot like /tmp. * read both the watermark and object * merge * echo Is it possible to skip one query and still be able to read ownership from a table and at the same time stream the object, witch lead me to the next question, I can't seem to be able to make imageCreateFromJPEG handle the direct stream, nor that I fetch it in an array, is any of this possible? imageCreateFromString should work on your un-watermarked image from the DB. When you need the watermark, you can load the watermark from whatever source you like (file with imagecreatefromjpeg or DB with imagecreatefromstring) You can then merge the two images (original and watermark overlay) in RAM with imagecopymerge calls, or perhaps playing with an alpha blend with imagealphablending first. Creating that tmp file and writing/reading to it is probably a pretty serious performance bottleneck that should be addressed for any kind of heavy traffic or large images. -- Some people have a gift link here.
