Hi there everyone,
First of all, let me thank you for your always-present help in this list; I (as
a newbie) appreciate it very much! :)
However, pardon me for I need to trouble you with another piece of text that
doesn't do what it should do:
I need to parse the raw-listing of an FTP into it's parts (the code comes from
the book published by Wrox, however, I don't have the book in my posession to
check the two versions against each other), but it returns an empty list. Here
is the code:
[code]
switch ($this->systype){ //Parse raw dir listing into fields
case 'Windows_NT': //Handle WinNT FTP servers
$re = '/^.' .
'([0-9-]+\s+)'. //Get last mod date
'\d\d:\d\d..)\s+' . //Get last mod time
'(\S+)\s+' . //Get size or dir info
'(.+)$/'; //Get file/dir name
break;
case 'UNIX': //Handle UNIX FTP servers
default: //case UNIX falls through to default
$re = '/'. //Regax to parse common server dir into
'^(.)' . //Get entry type info (file/dir/etc.)
'(\S+)\s+' . //Get permissions info
'\S+\s+'. //Find, but don't capture hard link info
'(\S+)\s+' . //Get owner name
'(\S+)\s+' . //Get group name
'(\S+)\s+' . //Get size
'(\S+\s+\S+\s+\S+\s+)' . //Get file/dir last mod time
'(.+)$/'; //Get file/dir name
break;
}
//Map short identifiers to full names
$type = array('-'=>'file','d'=>'directory');
$listing = array();
foreach ($temp as $entry) { //loop through raw listings
//try to parse raw data into fields
$match=preg_match($re,$entry,$matches);
if(!$match) { //if we could not parse the listings
user_error("The directory listings could not be parsed.");
return array();
}
switch ($this->systypes){ //Give fileds sensible names
case 'Windows_NT'; //Handle WinNT-style dir listings
$listings[] = array( //Put parsed data into readable format
'type' =>
is_numeric($matches[2]) ? 'file' : 'directory','permissions' =>
null,'owner' =>NULL,'group'=>null,'size'=>(int)$matches[2],
'last mod' => $matches[1],'name'=>$matches[3]);
break;
case 'UNIX': //Handle UNIX FTP-style dir listings
default: //case UNIX fails through to default
$strings[] = array( //Put data into readable format
'type' =>$type[$matches[1]],'permissions' => $matches[2],'owner'
=>$matches[3],'group' => $matches[4],'size' => $matches[5],
'last mod' =>$matches[6],'name'=>$matches[7]);
break;
}
}
return $listings;
[/code]
Since this function is called Is($directory); I tried this:
var_dump($ftp_server->Is($ftp_server->cwd));
However, I get null.
Why?
(It's not that I understand how the raw-listing is being parsed using regular
expressions, so it's why I'm asking :) )
Thanks!
