note 16844 added to function.fopen

i allways thought variables (also a filepointer is just a variable) needs to be global to access them in a function. but: function foo($filepointer) { while ($oneline != 'end') { $oneline=fgets($filepointer, '1024'); print $oneline; } } $filepointer=fopen("onefile.txt", "r"); $oneline=""; while (!feof($filepointer)) { $oneline=fgets($filepointer, "1024"); if ($oneline == "begin") { foo($filepointer); } print $oneline; } onefile.txt: row1 row2 begin row4 row5 ende row7 row8 prints all lines 1 time!! i thought that the filepointer when calling the function is at line 3 than, in the function, the filepointer will go to line 6 but after the function the filepointer in the global script got to be at line 3 again but he is at line 6 too!!! there is no global in the function, no "&" in function-call any answers because i don't understand -- http://www.php.net/manual/en/function.fopen.php http://master.php.net/manage/user-notes.php?action=edit+16844 http://master.php.net/manage/user-notes.php?action=delete+16844 http://master.php.net/manage/user-notes.php?action=reject+16844
