Thanks, Patrick!
It works! ftp_pasv($connect, true) will turns on passive mode so that
the ftp client will initiate the data connection and this will work
around the firewall. Then I enable FTP in the firewall and the script
can work without turning on the passive mode.
There is a further problem when I put the above script in a web page as
shown below.
<HTML>
<HEAD>
<TITLE>
Getting a directory listing with FTP
</TITLE>
</HEAD>
<BODY>
<CENTER>
<H1>Getting a directory listing with FTP</H1>
Here's what's in the remote directory:
<BR>
<BR>
<?php
$ftp_server = "myftpserver";
$connect = ftp_connect($ftp_server)
or die("Couldn't connect to $ftp_server.");
$result = ftp_login($connect, "myftpuser", "mypassword")
or die("Couldn't log in $ftp_server.");
$a = ftp_nlist($connect, "/");
foreach($a as $value){
echo $value, "\n";
}
?>
</CENTER>
<BODY>
</HTML>
Then I access it from Firefox with URL
http://localhost/SpringIntoPHP5/ch09/phpftp.php. The display is:
---------------------------------------------------------
Here's what's in the remote directory:
Couldn't connect to myftpserver.
---------------------------------------------------------
So it fails at ftp_connect($ftp_server) call. Does the PHP FTP
function work differently when running from a web page? Is there
anything related with Firefox? BTW, other examples from this book work
just fine when viewing from Firefox. Or is it because the script is
running under the account apache and this account does not have enough
privilege?
Thanks again!
