I have the following auth php script .. 

#!/usr/bin/php
<?php
function flog($msg){
        $fh = fopen("/tmp/apache_auth", "a");
        fwrite($fh, date("Y-m-d H:i:s")." - ".$msg."\n");
        fclose($fh);
}
$user = trim(fgets(STDIN));
$pass = trim(fgets(STDIN));
$pass = sha1($pass);
flog($user." - ".$pass);
flog(print_r($_ENV, 1));
foreach ($_ENV as $k => $v){
        flog($k . '=' . $v);
}
$conn = mysql_connect(...);
mysql_select_db(...);
$checkquery = "SELECT `id`, `expiry` FROM `auth` WHERE `user` = 
'".mysql_real_escape_string($user)."' AND `password` = 
'".mysql_real_escape_string($pass)."' AND `enabled` = '1' AND (`expiry` > NOW() 
OR `expiry` = '0000-00-00 00:00:00') LIMIT 1;";
flog($checkquery);
$check = mysql_query($checkquery, $conn) or die(mysql_error($conn));
if (mysql_num_rows($check) > 0){
        $row = mysql_fetch_array($check);
        if($row['expiry'] != '0000-00-00 00:00:00'){
                $update = "UPDATE `auth` SET `expiry` = NOW()+INTERVAL 1 MONTH WHERE `id` = '".$row['id']."' LIMIT 1;";
                $update = mysql_query($update, $conn) or die(mysql_error($conn));
        }
        flog("Yes");
        exit(0);
}else{
        flog("NO");
        exit(1);
}
?>

Here's what /tmp/apache_auth contains:
2013-12-12 19:30:17 - SELECT `id`, `expiry` FROM `auth` WHERE `user` = '...' 
AND `password` = '...' AND `enabled` = '1' AND (`expiry` > NOW() OR `expiry` = 
'0000-00-00 00:00:00') LIMIT 1;
2013-12-12 19:30:17 - Yes
2013-12-12 19:30:17 - dex - ...
2013-12-12 19:30:17 - Array

Am I doing it wrong ? Do I need to enable special flags in php/apache ?
