Wrong datatype for second argument

This is my script for counting file size in folders, but when I put this script on normal text page it shows error:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in statistics.php on line 20

<?php
if (session_id() == ""){
session_start();
}
$maxupload=1024000000; // in byte
$dir='jdownloads';
$notcount=array('index.html','listing.php','descriptionfile.txt');
dirs($dir);
$sizeinbyte=($_SESSION[tots]==0)?'0':$_SESSION[tots];
$_SESSION[tots]=array();
unset($_SESSION[tots]);
function dirs($dir){
global $notcount;
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
 if ($file != "." && $file != "..") {
if(is_dir($dir.'/'.$file)){
dirs($dir.'/'.$file);
}else{
if (!in_array($file, $notcount)) {
$fl=filesize($dir.'/'.$file);
$_SESSION[tots]=$_SESSION[tots]+$fl;
}
}
}
}
closedir($handle);
}
}
?>

PHP:

 

try not to use globals..

<?php
if (session_id() == ""){
session_start();
}
$maxupload=1024000000; // in byte
$dir='jdownloads';
$notcount=array('index.html','listing.php','descriptionfile.txt');
dirs($dir, $notcount);
$sizeinbyte=($_SESSION[tots]==0)?'0':$_SESSION[tots];
$_SESSION[tots]=array();
unset($_SESSION[tots]);


function dirs($dir, $notcount){
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
 if ($file != "." && $file != "..") {
if(is_dir($dir.'/'.$file)){
dirs($dir.'/'.$file);
}else{
if (!in_array($file, $notcount)) {
$fl=filesize($dir.'/'.$file);
$_SESSION[tots]=$_SESSION[tots]+$fl;
}
}
}
}
closedir($handle);
}
}
?>

PHP:

 

not working

 

I just put this

Error_Reporting(E_ERROR);
clearstatcache();
session_start();

PHP:

Is this good idea?

 

No,

the error is already being reported, statcache has no effect on this script, and the session is already being stared (and has nothing to do with the error anyway).

There's a dirs() call in xeons' script where $notcount isn't passed properly, which is probably causing the error.

 

<?php
if (session_id() == ""){
session_start();
}

function dirs($dir, $notcount)
{
$file = '';

if ($handle = opendir($dir)) 
{
while (false !== ($file = readdir($handle))) 
{
 if ($file != "." && $file != "..") 
{
if(is_dir($dir.'/'.$file))
{
dirs($dir.'/'.$file);
}
else
{
if (!in_array($file, $notcount)) 
{
$fl=filesize($dir.'/'.$file);
$_SESSION[tots]=$_SESSION[tots]+$fl;
}
}
}
}
closedir($handle);
}
}


$maxupload=1024000000; // in byte
$dir='jdownloads';
$notcount=array('index.html','listing.php','descriptionfile.txt');
dirs($dir, $notcount);
$sizeinbyte=($_SESSION[tots]==0)?'0':$_SESSION[tots];
$_SESSION[tots]=array();
unset($_SESSION[tots]);

?>

PHP:

try this one.. although i didnt test it..

 

Line 18...
