glob()
http://www.php.net/glob
How portable is glob?
How fast is glob? Being that it searches through the entire
filesystem, this could potentially take a long time (like if i have
wildcards early in the filepath pattern and lots of matches)
correct? If my file variations (wildcards) are just at the end of
of the filepaths and i don't have more than 1000 files in the
directory then will I most likely be 'alright' with glob (in terms
of time)? I have probably spent more time now 'considering' the
time implications of glob, than glob actually would consume when
operating...
Thanks for the quick response/solutions.

Glob works on all platforms.
Glob does suffer from performance issues above a certain number of
files, and this can be system dependant. If you're unsure how many
files it may return you'd be better using opendir/readdir.
Not sure where you got the idea that glob searches the entire file
system, but it's limited to either the current working directory or
the directory you specify. So if your PHP file is in /var/www/htdocs
and you do glob('*.txt') you'll get all .txt files in /var/www/htdocs.
And if you do glob('/tmp/*.txt') you'll get all .txt files in /tmp.

I wrote my own little function for a regex pattern match on files:
class FileHandle {
public static function copyReg($srcDir, $destDir, $regEx, $mkdir =
false) {
// ensure we have the right dir separator /(unix) \(win) and not at
the end
$srcDir = rtrim(str_replace(array('/','\\'), DIRECTORY_SEPARATOR,
$srcDir), DIRECTORY_SEPARATOR);
$destDir = rtrim(str_replace(array('/','\\'), DIRECTORY_SEPARATOR,
$destDir), DIRECTORY_SEPARATOR);
//echo "DEST: ". $destDir ." END";
if ($mkdir && !is_dir($destDir)) mkdir($destDir, 0777, true); //make
dir if not exists and mkdir
if ($handle = opendir($srcDir)) {
while (false !== ($file = readdir($handle))) {
//echo "$file\n";
preg_match($regEx, $file, $matches);
if ($file != '.' && $file != '..' && count($matches) > 0) {
//print("<pre>$regEx $srcDir $file \n=".
print_r($matches,true));
copy($srcDir . DIRECTORY_SEPARATOR . $file,
$destDir . DIRECTORY_SEPARATOR . $file);
}
}
return true;
}
return false;
}
}
Hope that helps. Don't know how good this will perform.

I'm not sure what the context of this was, but the speed of searching a
directory with a large number of files, e.g. 100,000s, also depends a
lot on the filesystem.

'ls' is just a plain binary (/bin/ls), not a system call. The regex
functionality is part of the shell, usually bash.

Hi Guys,
I need to sort an array of objects. I found this ( at a url that didnt let
me send this msg... ) and I would know how to do it, but I believe there
might be a cleaner, more elegant way to do it. In Java, you just need to
implement the interface Comparable and provide a method called compareTo (as
far as i remember) and then you can use one of the many sorting algorithms
generically on objects that are comparable...
Anyway, I didn't find something like that for PHP. Since I'm using symfony,
I had a bit of a play with the objects at hand and simply did a
sort($arrayOfObjects) and it did sort them by the id. Just wondering where
it got the information on what to sort on (not quite) correctly for my case?
Thanks for your interest.

I'm confused. The function you need is the one you mention in the
subject. All you need to do is create a function that compares two of
the objects, in whatever way you need it to, and returns -1, 0 or 1.
The pass that to the usort function - it doesn't care what type of
thing is in the array. Full details available at http://php.net/usort.

I just ment to say it would be nice to have it like in Java or C# where you
can implement an interface, called Comparable and define a function in the
class called compareTo which returns an integer smaller, equal or greater
than 0 by which elements can generically be sorted by in a collection. Since
PHP has arrays (hash maps) as the primary collection type, and they are very
good for storing sets or other collections, it would be nice to have a sort
function that would look, if the elements of the array have a compareTo
method (implement the Comparable interface), and if they do, then sort with
that. I find it a bit surprising that such a well designed programming
language doesn't have such a useful feature. I guess one could use one of
the gazillion libraries out there to do the same thing. Also, one could
argue that this further checking would slow down functions that are
primarily used for sorting strings. However, the answer could be also in the
ArrayObject class which is in php natively. Only it should implement all the
array functions that are there anyway, which shouldnt be too hard to do for
the PHP PL developers. Some more in depth documentation of that class would
also be helpful.
Anyway, I found a not perfect, but good enough solution:
Implement a static compare function in the class of the object and put a
function in my library, that is simply called myTools::sort that will get
the object class of the first element of the array (if there is one) and
sort according to the compare method implemented in that class (if it
exists), otherwise just use sort. The compare method takes the parameters as
self:
public class AClass { // implements Comparable {
public static function compare(self $obj1, self $obj2) {
return strcmp($obj1->prop1, $obj2->prop1); // e.g.
}
}
That way I will get an exception if there is an object in the array which
does not have that class, but i can live with that. At least i'll get an
exception and not another funny error, because the parameters are self,
right?
It might be better to define an interface called Comparable with that
method, but was not really necessary for my case.
Just a few thoughts to maybe improve PHP in the future. Hopefully there will
be a lot of interfaces and objects for collection types at some stage in PHP
natively, although that might clutter the namespace and could be realised
with libraries. What are your thoughts?

I've had decent luck so far with the SQL Server Driver for PHP
published by Microsoft since Jason pointed me to it a while ago.

Hello List,
in last times i recognize that some scripts/formmailer of customers get abused
by spammers.
Some scripts avoid to use smtp-server and do smtp-dialog by its own using
fsockopen etc.
Problem ist that if mails are sent by fsockopen directy to other servers they
not occur in server-maillog.
Only way to find them is viewing accesslog, bit it is really hard to make
relations between entries in accesslog
and spamreports from other servers.
My question is if there is a way to restrict fsockopen to use not port 25 or a
kind of logging which makes entries if fsockopen is used.
This gets more and more to a problem for us but we do not want to disable
fsockopen completely at the moment.
Is there a way to realize this?
Thanks,
Andre

Hallo Andre,
i dont know why you use sockets to send a mail but it is save to solve
your problems with a algorithm and architecture. I think you can use a
capcha to get the control again over your script.

I think there was a proposed change to allow php to log mail calls. I
was disappointed to see it did not get put in to php yet though. Would
help to pinpoint scripts being abused, especially in shared
environments.
