also wat does -> mean

ex.

$this->access_level

what does -> mean im trying to configure a passord system i downloaded from here.

Edit:

what is $_REQUIRE and what is the 'new' statement like

$newuser = new $user

or sumin like that...

Use google, type something along the lines of "php sessions tutorial"

Don't use .bmp files for web images, that 2 meg image in your website would be about 17k if you made it a gif.

To answer your question about the ->: in your expample

$this->access_level

means, access the method "access_level" in the current object "$this".

Check here for OOP in php 5: http://www.php.net/manual/en/language.oop5.php

And here for "OOP" in php 4: http://www.php.net/manual/en/language.oop.php

ok ok. well the

$this

object was not defined anywere it was in a

if()

function so hownwould it access something wen the object wasnt defined sorry for bein a pain in the ass just its complicated learnin at age 14 😛

the object is not called $this, $this is how an object calls itself.

the 'new' statement dynamically allocates memory when creating an object.

OOP is not something you can learn in a message board, there are quite a few tutorials on basic OOP.

thorpe

did you read the links that jerdo posted a few posts back? look

Gasolene

class Car
{
  var $make;

  function setMake( $make )
  {
    $this->make = $make;
  }

  function getMake()
  {
    return $this->make; // returns make by calling a property inside itself
  }

  function &getObject()
  {
    return $this; // returns a reference to itself
  }
}


$mycar = new car; // create an object
$mycar->setMake( 'honda' );

$yourcar = $mycar->getObject
echo $yourcar->getMake(); // outputs "honda"

ownedman

well that helps a bit thanks and just to make sure

$yourcar =& $mycar->getObject

the =& means make $mycar->getObject the same as $yourcar right?

now i just need to know wat $_REQUEST does and im set!

Gasolene


$yourcar = $mycar->getObject(); // $yourcar is now a copy of $mycar

$yourcar =& $mycar->getObject(); // $yourcar and $mycar are the same car

& means 'reference of'

ownedman

now just wat does $_REQUEST do then im set thanks alot ima gonna read the whole manual. sry bout the hassale

Gasolene

$_REQUEST is an array of all request variables.

a request var is a var passed in the url string, the headers, or in a cookie.

basically a request variable is any var that was supplied somehow by the user hence the name request.

search for $GET, $POST, or $_COOKIES
