[RESOLVED] Help getting correct file count "glob"

[imagewiz]

I am using the following code to return file count in directories, and sub directories but the code returns 0 until 2 files are found. If I change if ($total_files_home <= 1) to if ($total_files_home <= 0) or if ($total_files_home == 0) it returns 1 file even if directory is empty. What am I doing wrong? I am a novice in php.

Thank you for any help or a better solution.

<?php
$total_files_home = 0; 
$total_files_home = count(glob("../users/$username/{*.*}", GLOB_BRACE));
if ($total_files_home <= 1)
$total_files_home = 0;
else
$total_files_home = $total_files_home;

echo '<a href="manager.php?efolder=home">';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="Home" width="60" height="50"><br>Home<br></a>( 
'.$total_files_home.' )<br><br></font>'; 
foreach(glob('../users/'.$username.'/*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace('../users/'.$username.'/', '', $dir);
$total_files_sub = count(glob("../users/$username/$dir/{*.*}", GLOB_BRACE));
if ($total_files_sub <= 1)
$total_files_sub = 0;
else
$total_files_sub = $total_files_sub;
echo '<a href="manager.php?efolder='.$dir.'">';
echo '<font size=2>';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="'.$dir.'" width="60" height="50"><br>'.$dir.'<br></a>( 
'.$total_files_sub.' )<br><BR></font></a>';
}

?>

First off, you don't need the {} or the GLOB_BRACE because you're not giving a list of possible patterns.

Second off, have a look at the contents of the array that glob() returns. That should tell you why your expected count is off.

But here's a question:

if ($total_files_home <= 1)
$total_files_home = 0;
else
$total_files_home = $total_files_home; 

Why do you subtract 1 from $total_files_home when it's equal to 1 but not when it's greater than 1?

Weedpacket..Hi.. Thank you for your reply, as I indicted am a novice php coder.
I added the

if ($total_files_home <= 1)
$total_files_home = 0;
else
$total_files_home = $total_files_home; 

because I though that <= 1) meant if $total_files_home ment that if the if the $total_files_home was less than 1 it would produce 0.
I rewrote the code as follows;

<?php
$total_files_home = count(glob("../users/$username/*"));
echo $total_files_home;
echo "<br>";
foreach(glob('../users/'.$username.'/*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace('../users/'.$username.'/', '', $dir);
$total_files_sub = count(glob("../users/$username/$dir/*"));
echo $total_files_sub;
echo "<br>";
}
?>

auctual

<?require_once("../access.php");?>
<?require_once("../common.php");?>
<?php
$total_files_home = count(glob("../users/$username/*"));
echo '<a href="manager.php?efolder=home">';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="Home" width="60" height="50"><br>Home<br></a>( 
'.$total_files_home.' )<br><br></font>'; 
foreach(glob('../users/'.$username.'/*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace('../users/'.$username.'/', '', $dir);
$total_files_sub = count(glob("../users/$username/$dir/*")); 
echo '<a href="manager.php?efolder='.$dir.'">';
echo '<font size=2>';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="'.$dir.'" width="60" height="50"><br>'.$dir.'<br></a>( 
'.$total_files_sub.' )<br><BR></font></a>';
}

?

but then I get a 1 even if the directory or subdirectories are empty.
Thank you again.

Try using '.' in your glob() pattern instead.

bradgrafelman..Hi..
I tried with ., {.}, {, .}*, and a few others I found in several hundred forums.
Thank you very much for your help, I appriciate it.
It seems as though php 4.3 does not return a 0 count with glob,
It will only return 0 when I use this:

if ($total_files_home <= 1) 
$total_files_home = 0; 
else 
$total_files_home = $total_files_home;

But then it has to read two files before showing a count..

even pointing to empty directories returns a value of 1

<?php
$path = '../users/'.$username.'/test2/';
$files = glob($path . '*.*'); // glob() returns an array of filenames matching the extension
$num = count($files); // counts the php files
echo "there are $num files"; // displays how many there are 
?>

<?php
$dir_path = "../users/$username/test2/"; 
$count = count(glob($dir_path . "*")); 
echo $count; 
?>

always returns 1..

[Weedpacket]

Well, the [man]glob[/man] page says

Returns an array containing the matched files/directories, an empty array if no file matched or FALSE on error.

Note: On some systems it is impossible to distinguish between empty match and an error.[/quote]If it's returning false, count() would count that as one value.

On this computer (Windows XP), PHP 5 returns an empty array for glob('*') in an empty directory, but after digging a copy of PHP 4 out of the archives and unzipping it, I found it would return false (I know what glob was returning because I used var_dump() on its output).

[NogDog]

You could use empty() instead of count(), perhaps? empty() will return true if the value is an empty array or a Boolean false, n'est ce pas?.

Hi..
Thank you both for your responses.
I think it is the version of php, I have tried so many variations now.
I tried empty, but it just returned a blank page.

//$total_files_sub = count(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*")); 
$total_files_sub = empty(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*"));

So I replaced

//if ($total_files_sub <= 1)
if (empty($total_files_sub))

but I still get ( 0 ) for directories that have files.
I am going to have to try a host that has php 5 installed.
Thank you again..

I assumed that php 4.3 was running but I just
checked the version and it is PHP Version 5.2.6.

[imagewiz]

I tried this as well still returns 0 for directories with files until count is above 2

if($total_files_sub == '' && $total_files_subl !== 0 && $total_files_subl !== '0' && $total_files_subl !== "0" && $total_files_subl !== null && $total_files_subl <= 1)

[Weedpacket]

$total_files_sub == '' && $total_files_subl !== 0 && $total_files_subl !== '0' && $total_files_subl !== "0" && $total_files_subl !== null

Could be summed up by using NogDog's suggestion and writing !empty($total_files_subl) (assuming that the variable really is called $total_files_subl now, and that the use of $total_files_sub at the start of that line is a typo).

$total_files_subl <= 1) 

<= means "less than or equal to 1".

[imagewiz]

Hi.. $total_files_subl was a typo

if($total_files_sub == '' && $total_files_sub !== 0 && $total_files_sub !== '0' && $total_files_sub !== "0" && $total_files_sub !== null && $total_files_sub == false)
//if ($total_files_sub <= 1)

I am not sure what you mean "Could be summed up by using NogDog's suggestion and writing !empty($total_files_sub)"
I tried using

//$total_files_sub = count(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*")); 
$total_files_sub = empty(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*"));

and the page returned blank
I then tried

if (empty($total_files_sub))

and still get 0 until 2 files are uploaded to empty directory.
I am not sure where or how to use !empty($total_files_sub)
Thank you

Because you've got error reporting turned off and you're not giving [man]empty[/man] a variable.

$total_files_sub = glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*");
if(empty($total_files_sub))

[imagewiz]

Thank you, I got it now..

<?php
$total_files_home = glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/*.*"); 
if(empty($total_files_home))
$total_files_home = 0;
else
$total_files_home = count(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/*.*"));
$total_files_home = $total_files_home;
echo '<a href="manager.php?efolder=home">';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="Home" width="60" height="50"><br>Home<br></a>( 
'.$total_files_home.' )<br><br></font>'; 
foreach (glob('../users/'.$username.'/*', GLOB_ONLYDIR) as $dir) {
$dir = str_replace('../users/'.$username.'/', '', $dir);
$total_files_sub = glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*"); 
if(empty($total_files_sub))
$total_files_sub = 0;
else
$total_files_sub = count(glob("/var/www/vhosts/imagewiz.net/subdomains/ww2/httpdocs/users/$username/$dir/*.*"));
$total_files_sub = $total_files_sub;
echo '<a href="manager.php?efolder='.$dir.'">';
echo '<font size=2>';
echo '<img src="gfx/FolderIconV2.gif" border="0" alt="'.$dir.'" width="60" height="50"><br>'.$dir.'<br></a>(
