PHP version help

Hello all, I have an rss script that works fine on my test server but when I upload to a live server I get errors.

my test server is using php 5.2.1 and my live server is running php 4.4.6

here is the code:

rss_feeds.php

<?php

class OnlyHellRssFeed {

	private $nr_news= 10;
private $rss_channel = array();
private $currently_writing = "";
private $main = "";
private $item_counter = 0;
private $template;
private $feedname;
private $url;

function __construct($feedname, $url) {
  $this->feedname = $feedname;
  $this->url = $url;
}

function startElement($parser, $name, $attrs) {
   	switch($name) {
   		case "RSS":
   		case "RDF:RDF":
   		case "ITEMS":
   			$this->currently_writing = "";
   			break;
   		case "CHANNEL":
   			$this->main = "CHANNEL";
   			break;

   			$this->main = "IMAGE";
   			$this->rss_channel["IMAGE"] = array();

   			break;
   		default:

}

function endElement($parser, $name) {
   	$this->currently_writing = "";
   	if ($name == "ITEM") {
   		$this->item_counter++;
   	}

					//print ("rss_channel[$main][$item_counter][$currently_writing] = $data<br>");
					$this->rss_channel[$this->main][$this->item_counter][$this->currently_writing] = $data;

				break;
		}
	}
}

on my test server this works fine. on my live server I get an error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/admin/public_html/bb3portal/block/rss_feeds.php on line 9

any help is appreciated, thank you

ToonMariner · May 4, 2007

have a look to see if you live server has short tags enabled in the php.ini file.

caspert_ghost · May 4, 2007

short_open_tag On On

this is the same on both servers.

caspert_ghost · May 4, 2007

After searching around I found that php 5 added some new functionality to the code.

It turns out that maybe the code I have is not php 4 compatible.

Could you look see where the problem may be.

**some have said it may be the "private" code...

anyone?

taith · May 4, 2007

it would be something with the private $var;... try changing them to private $var="";?

caspert_ghost · May 4, 2007

it would be something with the private $var;... try changing them to private $var="";?

change "private" to $var= or add $var=

ie:

$var=$nr_news= 10;

or

private $var=$nr_news= 10;

caspert_ghost · May 5, 2007

The above rsss_feeds.php is not php 4 compatible.

anyone here can help me make it compatible?

I have changed all of the "private" to var, but still get errors.

thank you.

benjaminbeazy · May 5, 2007

__construct is new to 5, you have to make your constructor the same name as the class...

benjaminbeazy · May 5, 2007

i.e.

function OnlyHellRssFeed

caspert_ghost · May 5, 2007

so function OnlyHellRssFeed NOT class OnlyHellRssFeed

caspert_ghost · May 5, 2007

code as it is now (this site wont allow edits so I must create new post )

rss_feeds.php

with removing "static" and leaving function (getting closer)

Fatal error: Undefined class name 'self' in /home/admin/public_html/bb3portal/block/rss_feeds.php on line 80

benjaminbeazy · May 5, 2007

find that line and change

self::

to

$this->

and for any other you come across....

caspert_ghost · May 5, 2007

great so far so good. I got no errors however the feeds are not showing up... the feeds are in another php file called feedlist.php

after changing (there was only one) self:: to $this->

So I am wondering if I should combine the feeds and feedlist php's into 1 php file.

caspert_ghost · May 5, 2007

I decided this is just too much re coding so I will ask them again to update and if they refuse I will move to another host that offers up to date php and sql.

Thank you all for your help in this matter.

caspert_ghost · May 8, 2007

Well unfortunatly I must return to this issue as moving is now not an option for us at this time.

A re glimps of what has aspired thus far.

I have a script that is written in php 5 and I need some help in re writing it for php 4.

The original code is:

rss_feeds.php

<?php

class OnlyHellRssFeed {

private $nr_news=10;
private $rss_channel = array();
private $currently_writing = "";
private $main = "";
private $item_counter = 0;
private $template;
private $feedname;
private $url;

function __construct($feedname, $url) {
  $this->feedname = $feedname;
  $this->url = $url;
}

function startElement($parser, $name, $attrs) {
   	switch($name) {
   		case "RSS":
   		case "RDF:RDF":
   		case "ITEMS":
   			$this->currently_writing = "";
   			break;
   		case "CHANNEL":
   			$this->main = "CHANNEL";
   			break;
   		case "IMAGE":
   			$this->main = "IMAGE";
   			$this->rss_channel["IMAGE"] = array();
   			break;
   		case "ITEM":
   			$this->main = "ITEMS";
   			break;
   		default:
   			$this->currently_writing = $name;
   			break;
   	}
}

function endElement($parser, $name) {
   	$this->currently_writing = "";
   	if ($name == "ITEM") {
   		$this->item_counter++;
   	}
}

function characterData($parser, $data) {
	if ($this->currently_writing != "") {
		switch($this->main) {
			case "ITEMS":
				if (isset($this->rss_channel[$this->main][$this->item_counter][$this->currently_writing])) {
					$this->rss_channel[$this->main][$this->item_counter][$this->currently_writing] .= $data;
				} else {
					//print ("rss_channel[$main][$item_counter][$currently_writing] = $data<br>");
					$this->rss_channel[$this->main][$this->item_counter][$this->currently_writing] = $data;
				}
				break;
		}
	}
}

function get_data(&$template) {
			$xml_parser = xml_parser_create();
			xml_set_element_handler( 
			  $xml_parser, 
			  array($this, 'startElement'), 
			  array($this, 'endElement') 
			); 
			xml_set_character_data_handler( 
			  $xml_parser, 
			  array($this, 'characterData') 
			); 

			$data = self::curl_string($this->url);
			xml_parse($xml_parser,$data);
			xml_parser_free($xml_parser);

			// putting in array
			$news=array();
			if (isset($this->rss_channel["ITEMS"])) 
			{
				if (count($this->rss_channel["ITEMS"]) > 0) 
					for($i = 0;$i < count($this->rss_channel["ITEMS"]);$i++) $news[]=$this->rss_channel["ITEMS"][$i];
			}
			$c=0;

			foreach($news as $key=>$val)
			{
				if($c<$this->nr_news)
				{
					$template->assign_block_vars($this->feedname, array(
					'LINK' => $val['LINK'],
					'TITLE' => $val['TITLE'],
					'DESC' => $val['DESCRIPTION'])
					);
				}
				$c++;
			}
		}
private static function curl_string ($url,$user_agent='Mozilla 4.0'){

       $ch = curl_init();

       curl_setopt ($ch, CURLOPT_URL, $url);
       curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);
       curl_setopt ($ch, CURLOPT_HEADER, 0);
       curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
       curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
       curl_setopt ($ch, CURLOPT_TIMEOUT, 120);
       $result = curl_exec ($ch);
       curl_close($ch);
       return $result;
  
	}
}


?>

This gave the error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /home/admin/public_html/bb3portal/block/rss_feeds.php on line 9

When I change:

private $nr_news=10;
private $rss_channel = array();
private $currently_writing = "";
private $main = "";
private $item_counter = 0;
private $template;
private $feedname;
private $url;



private static function curl_string ($url,$user_agent='Mozilla 4.0'){

to: (removing the "private" code)

var $nr_news=10;
var $rss_channel = array();
var $currently_writing = "";
var $main = "";
var $item_counter = 0;
var $template;
var $feedname;
var $url;



var static function curl_string ($url,$user_agent='Mozilla 4.0'){

Parse error: syntax error, unexpected T_STATIC, expecting T_VARIABLE in /home/admin/public_html/bb3portal/block/rss_feeds.php on line 106

It was then said to remove "var static" and leave only function curl_string

the new error:

Fatal error: Undefined class name 'self' in /home/admin/public_html/bb3portal/block/rss_feeds.php on line 80

so I searched and found only 1 reference to self:: and changed it to $this->

now I get no errors but the list is not showing up as it should in my block.

there are 2 more files that go with this:

rss_feedlist.php

<?php

$feeds = array(
'mtgbks'	=> 'http://www.wizards.com/rss.asp?x=books',
'mtgdnd'	=> 'http://www.wizards.com/rss.asp?x=dnd',
'mtgd20'	=> 'http://www.wizards.com/rss.asp?x=d20modern',
'mtgebr'	=> 'http://www.wizards.com/rss.asp?x=eberron',
'mtgfr'		=> 'http://www.wizards.com/rss.asp?x=forgottenrealms',
'mtgmtg'	=> 'http://www.wizards.com/rss.asp?x=magic',
'mtgswrpg'	=> 'http://www.wizards.com/rss.asp?x=starwars-rpg',
);	
foreach ($feeds as $feed_name => $url) {
  $feed = new OnlyHellRssFeed($feed_name, $url);
$feed->get_data($template);
}

?>

and rss_feeds.html which is the output page.

if you could please look closley at this code and help with a rewrite for php 4 I would be gratly appreciative.

Thank you
