Php oop!

You mean spl_autoload_register

Yes,
sry for
small spell error

[CreativityKills]

I Like sql_autoload_register as it is time saver
coz does'nt need to require class in core or config file.
Nd then starting up new instization of class

$clas = new class;

to avoid it
just simple put

sql_autoload_register(function($class){
require $class.'.php';
});

then
use

$clas = new clas;

as it will auto require class on instization :D

You mean spl_autoload_register

I know the use of declaring a var globally but,
But I meant to say the same var in multiple functions, is it possible?

function some_func()
{
// using $api here
}
function some_othr_func()
{
// using $api here also
}

yes i know that you know it, but you asked so i replied
this will be done with global,
or by defining a global variable like PHP: $GLOBALS - Manual or PHP: define - Manual
in oop you have to use global too if you want to access for exaple database class

[softwarefreak]

$api = "4y3g3h3h3"; 

function some_func() 
{ 
global $api;
echo $api; 
} 
echo some_func();

[GumSlone]

is this possible in php procedural programming?

I want a variable that can be accessed inside all the functions,

like

$api = "4y3g3h3h3";

function some_func()
{
echo $api;
} 

I didn't found one so used the oo way..

class some_class
{
public $api = "4y3g3h3h3";

public function some_func()
{
echo $this->api; 
}
} 

$api = "4y3g3h3h3"; 

function some_func() 
{ 
global $api;
echo $api; 
} 
echo some_func();

main advantages
-> Easy for dividing problems into different categorys.
-> oop protects data much better than procedural way.
-> Whole Data resides within classes so u can easily edit/extend it in future.
->Reusability (a solution of single big problem can be used while solving bigger problems)
and NO. IT DOESNT HAS ANY SECURITY ISSUES..

hmm...

im a noob at oop ..... how do you call for a function within a function within the same class ?


i still dont get the real advantages of using oop ....

depends what type are you calling , possibilities are ...{PHP}
$this->method();
self::method();
parent::method();
static::method();
ClassName::method();


readability
flexibility
reusability (it's hard to explain, will try .. )
but evil for small application

suppose , social network application is there with following functionality ,
picture_gallery.php
user_list.php
message.php



obviously pagination is required ,
then why not create an class with all commonly required method() rather than implementing it for every other

both are in own ways :D bla bla bla lecture over :P

[something else]

i still dont get the real advantages of using oop .... i know in another topic gum mentioned being able to have similar function names but that doesnt seem to be worth it as without using oop you could have to functions one with 1 letter different in the name....
and the other reason i have forgot .....

i would also like to know what the dangers are of using oop:

OOP can be a force for both good and evil. Evil if you don't know what you're doing.

i dont want to start coding something that can be hacked easily

:D oop is just a way to write codes differently, A person writing OOP style code may not hold the knowledge like you coding in procedural manner :P

if you don't feel like "ohhh, the codes are so messy in my script", then carry on w/ your own way, & if yes, try OOP, I mean learn it when free ;)

Nope it does not is is very useful when creating large scale websites or classifying and modeling data Correctly, especially if you use AN OBJECT RELATIONAL DATABASE its good to use classed to model all your table data etc, a class is like a structure that can store information of the same data-type or classification.

So it makes your code cleaner and easier to read

[something else]

what im a little confused about when using oop it makes your script a lot longer
does this make it longer to process?

[antony2kx]

That is one way at something else

or you can do it by extending the first class by the second one

for example

class Class1{

public function functionInClassOne()
{
echo "hello worlds";
}



}


class Class2 extends Class1{

public function printHelloWorld()
{
   $this->functionInClassOne(); //this will use the methods in class 1 because u have extended it
}

}

so instance would be 

$instance = new Class2;

$instance->printHelloWorld(); 

as easy as it gets

[something else]

im guessing if you have got 2 classes then to use a function from the second class in the first class function you would use the same method as calling it outside the class?
eg:

<?
class someclass{

function function1(){
$c = new someclass2; 
$c->function2();
}

}

class someclass2{

funtion function2(){

}

}
?>
