[RESOLVED] Problem with big array

[Oni]

Hey--

I'm trying to the file list of a dr off of a ftp server and I've come to the point where the thing should display the data...

So, there is a pretty big array which gets built up, then I want to extract, for example the file/dir names...

Please excuse the sloppiness of the code, for now 😉

<?php
$ftp_host = "localhost";
$ftp_user = "anonymous";
$ftp_password = "anonymous";

//Connect
echo "Connecting to $ftp_host via FTP...<BR>";
flush();
ob_flush(); 
$conn = ftp_connect($ftp_host);
$login = ftp_login($conn, $ftp_user, $ftp_password);

//
//Enable PASV ( Note: must be done after ftp_login() )
//
$mode = ftp_pasv($conn, TRUE);

//Login OK ?
if ((!$conn) || (!$login) || (!$mode)) {
   die("FTP connection has failed !");
}
echo "Login Ok.<BR>";
flush();
ob_flush(); 
$mode = ftp_pasv($conn, TRUE);
//
//Now run ftp_nlist()
//
//$file_list = ftp_nlist($conn, "/");
//var_dump($file_list);

function itemize_dir($contents) {
   foreach ($contents as $file) {
       if(ereg("([-dl][rwxstST-]+).* ([0-9]*) ([a-zA-Z0-9]+).* ([a-zA-Z0-9]+).* ([0-9]*) ([a-zA-Z]+[0-9: ]*[0-9])[ ]+(([0-9]{2}:[0-9]{2})|[0-9]{4}) (.+)", $file, $regs)) {
           $type = (int) strpos("-dl", $regs[1]{0});
           $tmp_array['line'] = $regs[0];
           $tmp_array['type'] = $type;
           $tmp_array['rights'] = $regs[1];
           $tmp_array['number'] = $regs[2];
           $tmp_array['user'] = $regs[3];
           $tmp_array['group'] = $regs[4];
           $tmp_array['size'] = $regs[5];
           $tmp_array['date'] = date("m-d",strtotime($regs[6]));
           $tmp_array['time'] = $regs[7];
           $tmp_array['name'] = $regs[9];
       }
       $dir_list[] = $tmp_array;
   }
   //return $tmp_array;
   return $dir_list;
}
$buff = ftp_rawlist($conn, "/");
$items = itemize_dir($buff);



while (list ($line, $type, $rights, $number, $user, $group, $size, $date, $time, $name) = each($items)) {


print $name;
print "<BR>";
flush();
ob_flush(); 



} 




//var_dump($items);
//close
ftp_close($conn);

?>

When I want to display the $line var, it works fine, however when I try to display any other var out of the array I just get an empty spot... (Of course the <BR>s still print fine)

When going through an array with such a while() loop, the first element in the list() is the array key, the second is the array value..... what do you see when you look at $type or when you set error_reporting to E_ALL?

You'd need to list() the individual elements of the each array element - i.e,. list($line, list($type, ...)) = each($items), but a something a bit cleaner might be:

foreach($items as $line=>$item) {
list($type, $rights, /*...,*/ $name) = $item;
//...
}

Thanks for the reply--
I still see blanks?

foreach($items as $line=>$item) {
list($type, $rights, $number, $user, $group, $size, $date, $time, $name) = $item; 
//while (list ($line, $type, $rights, $number, $user, $group, $size, $date, $time, $name) = each($items)) {


print $type;
print "<BR>";
flush();
ob_flush(); 



}

If you've changed the name in the foreach loop to $items you need to change it to the same for function itemize_dir($contents) as it's running the loop on $items which hasn't be parsed to the function

Sorry--

I'm kinda lost.

I have the:

$buff = ftp_rawlist($conn, "/");
$items = itemize_dir($buff);

So $items is actually the result of the function?

[leatherback]

Yes: This line:

return $dir_list;

is the magic one: It tells the function to stop continuing, and give as output the $dir_list.

So, what you call the function like this:

$items = itemize_dir($buff);

The variable $dir_list is copied/moved into $items.

Pretty cool, he/

[Oni]

heh, yea that is not the problematic part. I was just saying what I thought, because it seemed to me that ClarkF1 meant otherwise, which I'm sure he didn't mean, so it seems I made a communication mistake.

However, now that there is an array, I'm having trouble getting set variables out of the array. 🙁

[leatherback]

is this what you are trying to do?

<?php
$ftp_host = "";
$ftp_user = "";
$ftp_password = "";

//Connect
echo "Connecting to $ftp_host via FTP...<BR>";
flush();
ob_flush();
$conn = ftp_connect($ftp_host);
$login = ftp_login($conn, $ftp_user, $ftp_password);

//
//Enable PASV ( Note: must be done after ftp_login() )
//
$mode = ftp_pasv($conn, TRUE);

//Login OK ?
if ((!$conn) || (!$login) || (!$mode)) {
   die("FTP connection has failed !");
}
echo "Login Ok.<BR>";
flush();
ob_flush();
$mode = ftp_pasv($conn, TRUE);
//
//Now run ftp_nlist()
//
//$file_list = ftp_nlist($conn, "/");
//var_dump($file_list);

function itemize_dir($contents) {
   foreach ($contents as $file) {
       if(ereg("([-dl][rwxstST-]+).* ([0-9]*) ([a-zA-Z0-9]+).* ([a-zA-Z0-9]+).* ([0-9]*) ([a-zA-Z]+[0-9: ]*[0-9])[ ]+(([0-9]{2}:[0-9]{2})|[0-9]{4}) (.+)", $file, $regs)) {
           $type = (int) strpos("-dl", $regs[1]{0});
           $tmp_array['line'] = $regs[0];
           $tmp_array['type'] = $type;
           $tmp_array['rights'] = $regs[1];
           $tmp_array['number'] = $regs[2];
           $tmp_array['user'] = $regs[3];
           $tmp_array['group'] = $regs[4];
           $tmp_array['size'] = $regs[5];
           $tmp_array['date'] = date("m-d",strtotime($regs[6]));
           $tmp_array['time'] = $regs[7];
           $tmp_array['name'] = $regs[9];
       }
       $dir_list[] = $tmp_array;
   }
   //return $tmp_array;
   return $dir_list;
}
$buff = ftp_rawlist($conn, "/");
//print_r($buff);
$items = itemize_dir($buff);


foreach($items as $line=>$item) 
  {
  echo "<p> Items:";
  echo $item['line']."<br />";
  echo $item['type']."<br />";
  echo $item['rights']."<br />";
  echo $item['number']."<br />";
  echo $item['user']."<br />";
  echo $item['group']."<br />";
  echo $item['size']."<br />";
  echo $item['date']."<br />";
  echo $item['time']."<br />";
  echo $item['name']."<br />";
  echo "</p>";
  }

Exactly want I want to do...
Thanks MUCH! 😃

[leatherback]

NP, you did the hard work (The eregi pattern).
