New Comment:
I have the same problem, but on windows xp.
The values are being selected back from mysql via ADODB. The values
being used (in variables) are 2 and 0 eg pow($value1,$value2) where
value1 = 2 and value2 = 0

PHP automagically tries to convert the passed data to a number
representation.
Please paste the exact values you are using to call this pow()

$result=mysql_query("SELECT id, cdate FROM newspaper WHERE
path='".substr($a, strrpos($a, "/")+1, strlen($a))."'") or die
(mysql_error());
$rec=mysql_fetch_array($result);
$e=pow(2, $rec[id]); //Warning!
it's looks like what pow() function can't convert $rec[id] variable
from string to integer automatically.
Using
$rec[id]=stettype($rec[id], "int");
helps
