[SOLVED] Noob question...

[aim25]

I know i should know this, but what are the => and the -> used for? I tried google but to no avail did i find what i was looking for

[corillo181]

if you a noob you shouldn't be aim for that yet, it's use to build class and that's when you ready for O.O.P

 

i haven't gone after it i'm still on functions.

[per1os]

The => is used generally as part of an array which signifies "index" => "value";

 

The -> is used generally in  OOP (Object Oriented Programming) $object->Property/Function to call a property or a function of that object.

You mean...?

 

<?php

$object->method($variable);

?>

 

<?php

$array = array('poop'=>'caca', 'pee'=>'urine');

?>

 

Look into OOP/Objects and arrays. But yeah, don't get ahead of yourself, start with the very basics. Will learn much much better.

=> Would be used in arrays

 

For the =>

array_keys => array_values;

 

And for the ->

Class->Function

<?php
$old = array('Bob'=>'World');
$new = str_replace(array_keys($old), array_values($old), "Hello Bob");
echo $new ;
?>

<?php
class MySQL {
  fucntion MyQuery($str_query) {

  }
}

$SQL = new MySQL;
$Res = $SQL->MyQuery("SELECT * FROM table");

?>
