Arrow Syntax

[Superian]

I have no idea how to use the arrow syntax, so could someone please write a simple example that outputs a string using the arrow syntax? The arrow syntax should work without using OOP, correct? Thanks!

$files->filename

It looks like you're calling the "filename" method on an object named "$files"..... therefor you're already using OOP. 

 

Here's a sample class how what I think you're trying to do:

 

 

<?php

class files{

   private $_filename='';

   

public function __construct($filename){

$this->_filename=$filename;

}

public function filename(){

return $this->_filename;

}

}

 

?>

 

 

Here's how you would instantiate it:

 

<?

 

$files = new files($filename);

$files->filename();

 

?>

 

 

 

Hope this helps.

There is no class, so how is OOP being used? I was thinking that there is way to use the arrow with out having to define a class, but I don't know how. Thanks!

I don't think the arrow is used for anything outside of OOP.

 

Unless you're just referencing an object's variable and not a method above I think what you're trying to accomplish is done with just a plain vanilla function

 

<?php

function filename() {
  // your code here
}

filename();

?>

I agree.

There isn't a method nor is there a class!

The -> is used to access methods/properties within an object. An object is created when a class is initialized or from a function which returns an object (such functions are glob or mysql_fetch_object)

I understand the mysql_fetch_object, but what do you mean by glob with in a function?

[wildteen88]

Sorry by glob I meant dir. I always get glob and dir mixed up.
