Re: [PHP] scheduling a script to check a directory for files
I need to write a script to import '.csv' data files into MySQL. My question is how can I have a script execute and check a directory every 4 hours for any '.csv' files and if it finds any calls a function to import them? On linux there is cron (you should find many example by googling) on windows there is the task scheduler... And then finally you can use PHPs delay func and a loop ;) The any part can be done by globbing, DirectoryIterator, shell scripts ..

So how can this foreach loop make PHP causing a stack violation?
Any ideas?
You can get the full source code here:
wget http://mawercer.de/marcweber/da.zip
(I'll remove the link again in some days)
I'm using PDO and mysql. The database configuration options can be found in
config.php
Everything should be done automatically. (It does create a class location cache
to autoload them and it creates a file containing database metainformation to
execute type safe data queries.(MPDO.php) If you like it keep and use it and
drop me a mail telling so ;)
Main entry point is index.php of course.
You need to click on link Kunden or use
http://localhost/.../index.php?page=Kunden
to get this error.
I did use PHP 5.2.2 and mod_php (apache) I didn't try cgi.

[PHP] Re: Iterators
What did I miss here?
In case somebody else wants to know.
I've found some examples in php sources ( ext/spl/tests/array_009.phpt )
This is the way to accomplish this:
$array = array(1, 2 = array(21, 22 = array(221, 222), 23 = array(231)),
3);
$dir = new RecursiveIteratorIterator(new RecursiveArrayIterator($array),
RecursiveIteratorIterator::LEAVES_ONLY);
foreach ($dir as $file) {
print $file\n;
}
Would be really nice to have some hints in documentation.

[PHP] static functions and array_map - why not allowed?
Why can't I use static functions in array_map?
Example:
?php
class Dummy
{
static public function T($a)
{
echo T called with $a\n;
return $a+2;
}
}
function t($a)
{
echo t called with $a\n;
return $a*2;
}
echo 'invoking Dummy::T works fine : ', Dummy::T(3),\n;
var_dump(array_map('t',array(1,2)));
var_dump(array_map('Dummy::T',array(1,2)));
?

[PHP] Where would you look for documentation about interface RecursiveIterator? RecursiveIteratorAggregate - suggestion
http://de.php.net/~helly/php/ext/spl/interfaceRecursiveIterator.html
This piece of code
?php
$array = array(1, 2 = array(21, 22 = array(221, 222), 23 = array(231)),
3);
$dir = new RecursiveIteratorIterator(new ArrayIterator($array));
foreach ($dir as $file) {
print $file\n;
}
?
results in
Fatal error: Uncaught exception 'InvalidArgumentException' with message
'An instance of *RecursiveIterator* or IteratorAggregate creating it is
required' in /tmp/t3.php:4
Stack trace:
/tmp/t3.php|4|
RecursiveIteratorIterator-__construct(Object(ArrayIterator))
#1 {main}
thrown in /tmp/t3.php on line 4
So this interface exists.
Why am I asking?
I've written a small html combinator library where each tag is represented
as object.
Now I want to iterate over them using RecursiveIteratorIterator.
To be able to iterate over subElements I have to provide subIterator
by exposing the interface RecursiveIterator, right?
I'd like to also implement IteratorAggregate instead
of Iterator because subtags are stored in arrays.
This doesn't work because RecursiveIterator does inherit from Iterator.
Thus I have to implement current, next, etc as well just beeing dummy
functions calling an internal iterator iterating over those elements?
Or is this much easier and there is a RecursiveIteratorAggregate interface?

This function should take all elements in all arrays and flatten them down to
one array.
Thus the result of the example above should be
array(1,2,..,6)

[PHP] Iterators

}
$a=iterator_to_array(new RecursiveIteratorIterator( A (A(2) , A (3,4),
A(5,6;

I'd expect this to output an array containing 2,3,4,5,6.
But the result is:
array(2) {
[0]=
int(5)
[1]=
int(6)
}
