I am learning classes (trying to anyway).

I have class called photo. It contains two functions:

create_folder()
sterilize_text()

In the create_folder function I want to clean user uploaded data before creating a folder based on that data. I have a few special rules so I wanted to put this in a seperate function instead of regexing all over my pages.

I read that using functions within functions in classes is easy, but I don't know how and the tutorial I'm using doesn't touch on using nested functions.

So what happens is when I invoke the class and use create_function(), php exits with this:

Fatal error: Call to undefined function: sterilize_text() in /var/www/html/includes/classes.php on line 34
Line 34 is : $brand = sterilize_text($myrow[brand]);

Is there a way to code this so I can use functions within functions, inside of my class? I've included the relevant scripts below.

Thank you.

class photo
{

	var	$model;

	// mk the folder for an uploaded image.
	function create_folder($model)
	{

		global $dbx, $dbxold;
		if (!isnum($model)||strlen($model)>5) {return(false);}
		
		$q = "SELECT brand FROM spec WHERE model='$model'";
		$result = mysql_query($q,$dbxold);
		$myrow = mysql_fetch_array($result);

		$brand = sterilize_text($myrow[brand]); 

		if ($brand=="") {return(false);}
		$webpath = "/images/dirtbikes/$brand";
		$uploaddir = $_SERVER["DOCUMENT_ROOT"] . $webpath;
		if (!file_exists($uploaddir)) {
			mkdir ($uploaddir, 0777);
			chmod($uploaddir,0777);
			if (!file_exists($uploaddir)) {
				echo "
unable to create directory. :(
";
				return(false);
			}
		}

		$dir_array[] = $webpath;
		$dir_array[] = $uploaddir;
		return $dir_array;

	}

	function sterilize_text($text)
	{
		$hyphen = 	"_";
		$dash = 	"-";
		$text = strtolower($text);
		$text = ereg_replace('[^a-zA-Z0-9_\\,]', '', $text);
		$text = ereg_replace('[\\]', $dash, $text);
		$text = ereg_replace('[,]', $hyphen, $text);
		return $text;
	}

}

create_folder($model); 

	echo "
";
	print_r($dir_array);
	echo "
";

?>
