[PHP] Re: how to check for a static call from an object
Sebastian Mendel wrote:
Hi,
how can i check if a method is called statically when called from inside
another object? (without debug_bactrace())
class foo
{
function bar()
{
if ( isset( $this ) )
{
return 'not static';
}
return 'static';
}
function bar2() { foo::bar(); }
}
sorry, my mistake
// returns 'static'
echo foo::bar();
// returns 'not static' but should be 'static'
$foo = new foo;
echo $foo-bar2();
so, how can i prevent a method from called static or not called static?
and btw. does anynone know why it is not good to let one function handle
both mehtods of calling (static and not static) as in PHP 5 you will get
notices if called wrong - but PHP doesnt support multiple
function-definitions like:
class foo
{
static function bar()
{
return ANY_DEFAULT_VALUE;
}
function bar()
{
return $this-value;
}
}
or even
class foo
{
static function bar( $param )
{
return $param;
}
function bar()
{
return $this-param;
}
}
or is this at least an issue for the internals-list?

Running this on 4.3.9 both as an apache module and
from CLI I get:
I am a regular function named B in class A.
I am not a constructor in A.
This is contrary to what the manual says:
This is fixed in PHP 4 by modifying the rule to: 'A
constructor is a function of the same name as the
class it is being defined in.'. Thus in PHP 4, the
class B would have no constructor function of its own
and the constructor of the base class would have been
called, printing 'I am the constructor of A.br /'.
Is this an error in the manual?
Or a bug in php 4.3.9?
Or just me being stupid?
as i understand it exactly as you, it must be a bug/error

The problem was more complex than I described, I instead wrote a sorting

The array multi-dim array looks like this (short version). The total element

wanted to sort them first on total and if the total was the same I wanted
to sort them with the highest point in a specific tournament, and so on. I
have not found an simple solution to this using any built in functions. So I
thought is was the best to sort it manually. My algorithm is problably not
efficient, but it works just fine for this solution. You can find the

There isnt an error at all. According to the die() functions at the end
of the mysql() functions it should give it there, instead I get blank as
if the function has not successfully completed. The reason I say this
is if you try to access the mysql resource pointer ( $db, in this case )
I get nothing, a return code of 0. Example in point...
function db( $host, $user, $pass, $dbnam ) {
$db = @mysql_pconnect( $host, $user, $pass )or die( font
face=\arial\bphpDHCPAdmin currently not active, is under repair or
is not configured correctly./bbrbrError Number: . mysql_errno(

@mysql_select_db( $dbnam )or die( font face=\arial\bCould

@mysql_error( $db ) . br . Error Number: . @mysql_errno( $db ) .
brEmail Administrator: a

return $db;
}
function logs() {
global $defined;
db( $defined[9], $defined[1], $defined[2], $defined[3] );
$pagecount = 1;
$tble = logs;
$sql = @mysql_query( SELECT * FROM $tble WHERE session =
\$_SESSION[hash]\, $db )
$db is not defined,
$db is not required,
at least if you want to use $db you have to ctach the return from db()
in $db:
$db = db( $defined[9], $defined[1], $defined[2], $defined[3] );
as i assume, logs() does nothing more than update one row with session
data in the DB?
if you have a primary key on `session` you can just user REPLACE instead of
if SELECT INSERT ELSE UPDATE
logs()
{
db( $defined[9], $defined[1], $defined[2], $defined[3] );
$sql = 'REPLACE INTO logs VALUES ( ... )';
mysql_query( $sql ) or die( '...' );

[PHP] Re: find duplicated values in array and count them
Patrick Fehr wrote:
Hi all
I need to compare values of multiple arrays, the tricky thing: I can't just
use array_diff, because I also need to count all the occurences and give
them back. The more tricky thing: It's a foreach loop through $arr[x
['comparable value'] while x is 1,4,3,6... so it's not that easy to compare
one item in the array under index 4 with the next one(which is in 3)
because foreach just loops.
The idea is: If two keys of different arrays hold the same value, I want to
just show one entry and tell the same time, how often it occurs(in other
arrays), so I don't show all the entries(as I would, if they weren't the
same.
But it is still a bit more complicated, because: only if the date_s value
lies 7 days from each other, I want to concatenate them to one entry +
show the number of occurences.
In the example below, the lessons 18 and 15 fit that need.
so I want them to be shown as:
[room] : Raum1
[teacher] : Marianne
[class] : SundayClass
starttime : 1099404000 (which is Array[19][date_s])
endtime : 099418400 + 7*24*60*60 (which is Array[15][date_e])
