-> help

So I have been looking code to understand it more.

The following came up.

 

 $database->removeActiveUser($this->username);

 

Could anyone point me in the right direction to working out what this means?

I assume the $database is for the include page called database.

 

Thanks

$database is a class object. And removeActiveuser is a method of the class $database or a method in a class $database inherits.

 

The -> operator is like the . (dot) operator in JavaScript, Java, C, etc.. If you know Perl, that operator is the same.

Beaten but wth,

 

Read a tutorial on Classes, that will tell you all you need to know, and will explain much faster/better than on here.

Look for a few, they will show you what is going on here.

 

$database is an instantiated class.

removeActiveUser() is a method of that specified class.

This method requires an argument of (im guessing) a username.

The username is stored in the current class you pulled this code from. (authentication class?).

It's Object Oriented code.  The '->' is an object-to-member operator.  removeActiveUser() is a method (read: function) of the $database object.  $this->username is the argument passed to that method, and is a data member of whatever object's class code you're currently reading.

Very grateful for all the responses. It is something I really need to get to grips with.

So the -> is the same as the . in C#? In that case, I understand what it does.

 

The $this is one i have seen often, it there a reason to use the word this?

I'll look on that link thankyou.

The following in PHP:

 

$this->someDataMember;

 

Is the same as the following in C#:

 

this.someDataMember;
