use of classes seems not to work???

djpirra

Hi there,

I am coding some PHP classes for a project i need.

the structure i am making is:

<?php
class Classname{

var $one;
var $....

 function Classname(){
      ...
 }

...
}
?>

right??

but when i make a php webpage and use the

<?php
require ("name_of_class.inc");
?>
<html>
<head>
.......
<body>

$classone = new Classname();

</body>
</head>
</html>

it seems to get some error at the require because the website appears blank coded! ("no code")
if i remove the require and the instance creation it works fine and displays the html code!

what can be wrong'???

Set error_reporting to E_ALL in php.ini

You'll have to check and see that the path to the included file is correct.

i don't have access to admin privileges...

[man]error_reporting[/man], and while you're about it, look at the generated HTML to make sure there's nothing there that's not getting rendered.

hey i think i have found the bug!

in php i can't use 2 constructors?? for diferent number of parameters??

Like:

class FTPligacao{

var $host;
var $port;
var $username;
var $password;
var $remotedir;
var $id_ligacao;

function FTPligacao($username, $password)
{
	$this->$host="127.0.0.1";
	$this->$port=21;
	$this->$username=$username;
	$this->$password=$password;
	$this->$remotedir=".";
	$this->ligar();
}

function FTPligacao($host, $port, $username, $password, $remotedir='')
{
	$this->$host=$host;
	$this->$port=$port;
	$this->$username=$username;
	$this->$password=$password;
	$this->$remotedir=$remotedir;
	$this->ligar();
}

....
}

ERROR:

PHP Fatal error: Cannot redeclare ftpligacao() in ....

Yes, PHP4 does not support function overloading.

What you could do is:

function FTPligacao($username, $password, $host = '127.0.0.1', $port = 21, $remotedir = '.')
{
	$this->$host = $host;
	$this->$port = $port;
	$this->$username = $username;
	$this->$password = $password;
	$this->$remotedir = $remotedir;
	$this->ligar();
}

thats kinda poor programming no??

I can't have more that one constructor?? brrrr thats bad!

Java is more cool related to that (in OOP) term then...

Anyway if someone knows how to manage this using diferent parameters just let me know!

okie dokie 😉

Another thing is... the ftp_connect seems not to work...

xeck the error:

PHP Notice: Undefined variable: host in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34 PHP Notice: Undefined property: in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34 PHP Notice: Undefined variable: port in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34 PHP Notice: Undefined property: in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34 PHP Warning: ftp_connect() [function.ftp-connect]: php_hostconnect: connect failed in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34 PHP Fatal error: Maximum execution time of 30 seconds exceeded in C:\Program Files\Ensim\Sitedata\pirra\Inetpub\wwwroot\ftpclass\ftpclass.inc on line 34

i am using a valid host and port with a valid username and password!

whereve you're calling ftp_connect, $host, $port, and some property of the object (i.e: $this->foo) are undefined. so, figure out why that may be.

laserlight

I have used ftp_connect() successfully before, so unless it is a fault with your copy of PHP, it is probably just your PHP script needing some bugfixing.

Instead of immediately blaming PHP, look over your ftpclass.inc file and try to fix the problem.

Not quite as good as Java yet, huh? I think this is supposed to be solved in PHP5, overloading methods and constructors.

ahundiak

PHP5 will not support method/functioning overloading nor are there any plans to do so. Trying to implement overloading in a typeless language would be challenging to say the least.

i am not blamming PHP...

i use

$id_ligacao = ftp_connect($this->$host, $this->$port) or die("Erro ao ligar ao servidor " . $this->$host);

with $this->$port = 21
and $this->$host="127.0.0.1"

so it should connect to the local ftp server on port 21...

It doesn't make the DIE... it's odd..

djpirra

Ok now it connects but the RAWLIST and NLIST seems to be BUGGY... SO this was all worked for nothing damn.....

No solutions ;(

What problems do you have with [man]ftp_rawlist/man and [man]ftp_nlist/man?
