PHP and structs...

Hi all,

In JavaScript, there exists this

Code:

var userPosition = 
{
  posX : 0;
  posy : 0;
}

Then, a variable can be accessed inside, so, basicaly, userPosition is a type of variable...
Does PHP have that too? I was looking fo that, but i dont think I have found it...
Sorry for a silly question and thanks for some feedback

Arrays can be used for that, eg:

Code:

$pos= array ('posX'=>0, 'posY'=>0);
printf ("You're at %d,%d\n", $pos['posX'], $pos['posY']);

The construct that is available in PHP, Perl, JavaScript, and many others ... usually at the exclusion of "structured types in the 'C' or COBOL sense" ... is called a hash table. The elements are keys, and they are looked-up by name at runtime in a construct that can have any number of keys. (And, fair warning, does not notice if a mispeled key is inserted.) However, the arrangement is flexible, efficient (enough), and very powerful.

Furthermore, the nomenclature is abused. What one language calls an "array," another might call a "dictionary," and an "array" is not a "C/C++"-like thing at all. There is rarely, if ever, any means of "compile-time checking."

A twist, maybe? Classes...

the class

Code:

<?php
class person
{
  var $name;
  var $age;

  function person ()
   {
    $this->name = "";
    $this->age = 0;
   }

  function setName($name)
   {
    $this->name = $name;
   }

  function setAge($age)
   {
    $this->age = $age;
   }

  function getName()
   {
    return $this->name;
   }

  function gtAge()
   {
    return $this->age;
   }
}
?>

and in the code:

Code:

include /repository/person;

$array = new Array();

// in the loop
$aPerson = new person();
$aPerson->setName($somevalue);
//ect
$array[$counter] = $aPerson;

Maybe a feasable twist?

Still testing that, dont get data OUT the other eng

If you need to combine PHP and Javascript, check out JSON.stringify in Javascript and json_encode/json_decode in PHP.

...or

use a simple two-dimensional array...

Sorry for the fuss gang...
