Bug description: sprintf() function bug with classes
Description:
------------
I think there is a bug with sprintf() function when I use it with more
than one % to format variable output.
Example:
If I use two %s %s it crashes, but if I use only one %s or static values
the sql query is valid and no warning errors happen. I think this is
really strange, and I don't think I've mistake my php code, I code for
some years..
Reproduce code:
---------------
class bdsql
{
function query($sql="",$vars="")
{
$sql=sprintf($sql, $vars);
[EMAIL PROTECTED]($sql);
return $result;
}
}
class kwww extends bdsql
{
function load_data($cat="",$scat="",$min=0,$max=10)
{
$result=$this->query("SELECT * FROM sites WHERE cat='%s' AND scat='%s'
LIMIT %d,%d;","addslashes(htmlentities($cat)),
addslashes(htmlentities($scat)), $min, $max");
}
}
How to use (index.php):
$ret2=$kwww->load_data("computadores","internet",0,5);
Expected result:
----------------
Execute the SQL query with no warning errors...
Actual result:
--------------
Warning: sprintf(): Too few arguments in c:\program
files\apache\htdocs\kwww\kwww.php on line 38
