static functions
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);
$dir = new RecursiveIteratorIterator(new
Why can't I use static functions in array_map?
Example:
?php
class Dummy
{
static public function T($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;

Hi,
Having this array:
$arr = array(
'my var'='My Value'
);
Notice the space in 'my var'.
Converted to object:
$obj = (object)$arr;
How can I access $arr['my var'] in $obj ?
-thanks!

print $obj-{'my var'};
$obj-{'my var'} = 'My New Value';
print $obj-{'my var'};

is it true that echo is a bit faster than print()? in general, when we don't
need a return value, which one is better to choose?

Yes, echo is faster than print. I would suggest echo over print since it
is shorter and faster :)
As referenced in the manual ( http://us2.php.net/manual/en/function.echo.php ),
check out this url:

Short story, there is a difference, but the speed difference is negligable.
If anyone cares, I prefer echo too. Not sure why. Shorter
If I use add slashes, it strips everything, I just want to replace all the

Is there an easy way in php to round to the nearest 500?
Yeah
$rouned = round($val/500) * 500;
I've always questioned the round() function.
I believe it has a downward bias, am I wrong?

Try this
$string = 'Hello person. How are you?';
You could use addslashes():
http://us3.php.net/manual/en/function.addslashes.php
Or, the code you mentioned below, could be rewritten like:
str_replace(\,\\,$code);
or
str_replace('','\',$code);
And if you're doing it for a MySQL query call, then you want to use
mysql-real-escape-string()
echo is slightly faster than print and it takes multiple arguments so
instead of:
echo 'p' . $test . '/p';
you can do
echo 'p' , $test , '/p';
which should be faster, and I say 'should' just because as print should be
slower because it has to go into the trouble of setting up a return
For downward rounding, you'd always want to use floor() and use ceil() for
rounding up. round() rounds up on a 5, down on a 4 and below.
Example:
echo round(141.074, 2); // 141.07
echo round(141.065, 2); // 141.07
I thought round() (or maybe it was a rounding function in another language or

hah yeah, always worth a little skepticism, but it seemed to make some kind of
sense. If you always round up or always round down, that's obviously not
right and you end up losing potentially a lot of money or over-estimating the
money involved.

Ok, screw work.. it's snowing out anyway (not that that makes a real difference
to doing PHP work inside), curiosity got the better of me.
btw.. the banker rounding code here was pulled from the round() manual page.
It's not what I read before, but it's the same concept:

Ahh.. good call.
http://en.wikipedia.org/wiki/Rounding
Apprently it's called banker's rounding or statistician's rounding and is a
little more complicated than just looking at the odd/even of the digit being
arounded.
This is starting to get into some heavy math theory and scary stuff that

I don't buy zero doesn't count. But again, this is getting into serious
math. It should be good enough to say 0-4 = 0, 5-9 = 10, but if you don't keep
strict high precision throughout the whole process and round at every step,
things are going to be off no matter what. It's just a matter of

Bridge is way more harder to learn.

I read on php.net about resources, the type

Is simply looping through the result set with

In this case, it's USUALLY much more efficient to write an SQL query
to perform the calculation.
