php OOP - call static method from another class within class

Question

I have the following class to another class in my main class.

class Products 
{
 public function __get( $key ){
 return trim(functions::mssql_escape_string_rev($this->fields[ $key ]));
 }
}

This beings back error: Call to undefined method functions::mssql_escape_string_rev()

Is there something wrong with my syntax or can this not be done?

Below is code used to autoload classes, this works for everything else so I know there is nothign wrong with the code. It just doesnt seem to initiate within the class.

// autoloader function called when we try to instantiate a class but haven't included the file
function __autoload($resource_name){
 $resource_name = trim($resource_name);
 try { 
 $filepath = CLASS_PATH."/class.".$resource_name.".inc.php";
 if(@!include($filepath)){
 throw new Exception('');
 }
 } catch(Exception $e) {
 exit("Could not find the required file: ".$resource_name);
 }
}

*******EDIT***** Please ignore this, I made a stupid mistake and included the functions::mssql_escape_string_rev twice. Sorry for timewasting..

• hungneox: "functions" is your another class?
• Sudantha: Does functions is a class you defined ?
• LeeTee: yes, it is a class full of static functions.
• LeeTee: I use an autoloader so I do not have to include each class. This works when I am not wihin another class.
• tereško: Are you aware that there is a huge difference between object oriented programming and class oriented programming. Instead of creating a static class, you should just use simple function, wrapped in a namespace. Additionally: use PDO.

Answer 1

As the error says the problem is that functions::mssql_escape_string_rev() is not defined.

Since we can't see what you think is the definition we can not really help you.

For me it looks like the call should be Functions::mysql_escape_string_rev() with capital F and mysql.

Update

Calling static functions from another class works normally: http://codepad.org/wrfm5X7j

Maybe you are calling mysql_escape_string_rev before you included the functions class.

• mAu: Why shouldn't he be using mssql? But I agree with the capital F.
• PiTheNumber: Oh, he could. But since we don't know, I can only guess and mysql is more likely then mssql.
• LeeTee: I am using mssql not mysql. Also my class functions is with a small f not capital. Therefore my method title and class title is correct PS. I'm a she ;0)
• LeeTee: Do I need to add define functions within my class? I really am at a loss to see whats wrong here..
• PiTheNumber: oh, sorry about that! How about posting the declaration of functions::mssql_escape_string_rev()?
