[SOLVED] Variable Not Assigning in Class Constructor

[dimkasmir]

This is the code for my class constructor as well as one function:

 

class geocoin
{
function __construct($track)
{
	$this->tracknum = $track;
}

function returnTrackNum()
{
	return $this->tracknum;
}

 

However, the variable $tracknum does not set because when I run this code:

 

$coins = new geocoin("test");
$num = $coins->returnTrackNum();
if (!isset($num))
{
echo "fail";
}

 

I can see that it is empty. Can someone tell me what I am doing wrong?

[samshel]

define tracknum as member variable

 

class geocoin
{
          private tracknum;
          function __construct($track)
{
	$this->tracknum = $track;
}

function returnTrackNum()
{
	return $this->tracknum;
}

Now I get this errror:

 

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or '}' in /homepages/13/d196500339/htdocs/geocoins/geocoin.php on line 4

[samshel]

class geocoin
{
          private $tracknum;
          function __construct($track)
{
	$this->tracknum = $track;
}

function returnTrackNum()
{
	return $this->tracknum;
}

 

oops ..forgot the $ sign...

[dimkasmir]

Nope, still getting the same error.

[samshel]

class geocoin
{
          var $tracknum;
          function __construct($track)
{
	$this->tracknum = $track;
}

function returnTrackNum()
{
	return $this->tracknum;
}

 

try this..

That should be working fine, what version of php are you using?

[dimkasmir]

I'm not getting an error anymore but this time it's echoing fail again.

[samshel]

i think u r using PHP4...

try this..

class geocoin
{
          var $tracknum;
          function geocoin($track)
{
	$this->tracknum = $track;
}

function returnTrackNum()
{
	return $this->tracknum;
}

I've solved this problem: my host was defaulting to PHP 4. All I had to do was make a .htaccess file. Now I have a new problem. Later in the script I use the file_get_contents() function. However, the host has URL file-access disabled. Is there anyway to enable it without having access to the php.ini file?

[samshel]

u want to read a URL?

[dimkasmir]

yes

[samshel]

sorry ! i am not aware of a work around for this ! but that flag is specially defined to block such thing, so my assumption is it will be difficult to fo a workaround...but may be i am wrong.

[trq]

In your .htaccess....

 

php_flag allow_url_fopen on

[trq]

Actually, I think that will only work in versions lower than 4.3.4. It seems you need access to the ini file to enable that setting now.

[dimkasmir]

I was able to change this by making an ini file in the directory. Now after I launch the script a few times and everything displays correctly, its stops reading the page for some time. Then if I launch it again a little later it works but after a few times stops working again. Is there any way to fix this? Also, is it possible to read only a part of the file, not the whole thing?

Is there any way to fix this?

 

Wouldn't know without seeing the relevent code.

 

Also, is it possible to read only a part of the file, not the whole thing?

 

No.

	function getPage()
{
	$this->page = file_get_contents("http://www.geocaching.com/track/details.aspx?tracker=".$this->tracknum);
	return $this->page;
}

function getName()
{
	preg_match('#<span id="ctl00_ContentBody_lbHeading">(.+)</span>#', $this->getPage(), $match);
	if(isset($match[1]) && $match[1] != '')
	{
		$this->name = $match;
		return $this->name[1];
	}
	else
	{
		return FALSE;
	}
}
