Andrew Farley :

There is a bit of a problem with this code that makes it not exactly equal to PHP 5.3’s get_called_class(). The get_called_class() works when calling the static function with the prefix classname, but it doesn’t work when called from within another static method of that class with self:: For example…

class Account extends Generic {

}

class Generic {
public static function getDBName_static() {
return strtolower(get_called_class());
}

public static function this_fails() {
return self::getDBName_static();
}
}

When I call Account::getDBName_static(); it properly returns “account”. But, when I call self:: this_fails(); it returns “self”, when it should be returning “account”. This is a odd use-case, but since I’m extending my base class with other classes I cannot define the class name as in my first example, I must use self:: in my static methods so they extend properly. I don’t have time to fix it right now, but I will have to fix it eventually, just wanted to see if anyone has noticed this, and/or anyone has fixed this problem already.

Cheers!

This could be fixed with a simple while loop after the backtrace, where it continues to seek back while the class name is self.

It has been awhile since I wrote this function, but I believe the purpose of the static variables was in a case where get_called_class() was called in such a way that it backtraces to the same line. Without the static variables, it would return the first class both times, but with the static variables, it would recognize that this is the second scan of the same line.

Line 13 / 14 should reset the variables if it is not the same as last time, but it sounds like it is not working properly.

class Account extends Generic {

}

class Generic {
public static function getDBName_static() {
return strtolower(get_called_class());
}

public static function this_fails() {
return self::getDBName_static();
}
}

When I call Account::getDBName_static(); it properly returns “account”. But, when I call self:: this_fails(); it returns “self”, when it should be returning “account”. This is a odd use-case, but since I’m extending my base class with other classes I cannot define the class name as in my first example, I must use self:: in my static methods so they extend properly.

My function works with instance calls, self calls, call_user_func(_array)? calls (thx Jrgns) and return false when called outside a class

if (array_key_exists(3, $bt)
&& array_key_exists(’function’, $bt[3])
&& in_array($bt[3]['function'],
array(’call_user_func’, ‘call_user_func_array’))
) {
if (is_array($bt[3]['args'][0])) {
$toret = $bt[3]['args'][0][0];
}
}
