Description:
------------
when trying to use sqlite_create_function() & passing a class method of $this apache dies orribly (appreciate it may be an apache issue)

Win XP Pro / php 4.3.3 compiled (MSVC) against apache 2.0.47

eg 
sqlite_create_function($this->db, 'link_keywords', array( $this,'linkers' ) , 1);
/*OR*/
sqlite_create_function($this->db, 'link_keywords', array( &$this,'linkers' ) , 1);

note that calling an external class method or normal function [array($ext_class,$method)]gives no problem , just methods of $this

not tested on apache 1.* 



Reproduce code:
---------------
class sqlite_help{
	function sqlite_help(){
		$this->db = sqlite_open('e:/phpdev/cp/my_admin.sqldb.eng', 0666, $sqliteerror);
		sqlite_create_function($this->db, 'link_keywords', array( $this , 'linkers') , 1);
		return $this->db;
	}
	function get_single( $key ){
		$res = sqlite_query( $this->db,"SELECT link_keywords(var) FROM my_admin WHERE key = '$key'" );
		$r = sqlite_fetch_array( $res , SQLITE_NUM );
		return $r[0];
	}
	function linkers( $str ){
		$keywords = array('phpmyadmin'=>'<a href="http://localhost/phpmyadmin/index.php"">phpMyAdmin</a>');
		foreach($keywords as $k=>$v){$str = str_replace( $k , $v , $str );}
		return nl2br( $str );
	}
}
$yaks=new sqlite_help();
echo $yaks->get_single('general');

Expected result:
----------------
str_replaced data from DB

works if function is external or external class method

Actual result:
--------------
an MS 'Apache has encountered an ....' etc Dialog no apache error log available , no PHP error logged.

The problem is the reference to $this from the generated sqlite (php)function. See ext/sqlite/tests/sqlite_oo_029.phpt on how to work around.
 [2003-12-27 17:17 UTC] helly@php.net
This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
