Description:
------------
I'm using PHP 5.1.6 on a production server with a LAMP setup, and I do code PHP on it remotely every day.

-- can't upgrade at the moment to 5.2.4 - would take people offline...sorry! Maybe later at night :)

No changes were made to php.ini, except for display_errors = On
No changes to the default mysqld config

I stumbled upon the bug with the mysql_data_seek() function - in short the problem is that if I spell it as mysql_daat_seek() instead (with the relevant args), no error is displayed. The page just displays normally - as if I had commented out the line.

It's trivial to me, but I guess it might give someone debug nightmares if he/she has several thousands of lines of code, IMHO :)

Reproduce code:
---------------
$result_prepaidcards = mysql_query("SELECT * FROM atrium.prepaidcards WHERE vendorid = '".$row_vendors['id']."';");

						if(mysql_num_rows($result_prepaidcards) > 0)
{
	for($i = 0; $i < mysql_num_rows($result_prepaidcards); $i++)
	{
		mysql_daat_seek($result_prepaidcards,$i);
		$row_prepaidcards = mysql_fetch_assoc($result_prepaidcards);
// more code here...

	}
}

Expected result:
----------------
I should see a syntax error line for the erroneous mysql_daat_seek() line...

Actual result:
--------------
The page displays just as usual, NO errors raised! Seems a problem with the syntax checker, or am I wrong?
