[SOLVED] Coudl someone explain this line of code

[rv20]

$page = (isset($_GET['page'])) ? $_GET['page'] : "main";

 

Really just the isset the "?" and generally what it is doing

[dennismonsewicz]

its short hand for an if/else statement. if page is set then get page else do whatever "main" is

[Philip]

To add onto what Dennis said, it's called a ternary operation.

And isset checks to see if the variable has been set (is set)

If you need more information, look up Ternary Operator

Ok so in longhand,

 

 

if (isset($_GET['page']) == "")){

 

$_GET['page'];

 

}else{

 

$page = "main";

 

}

 

 

that doesn't make sense if $_GET['page'] is not set then $_GET['page']

 

[Axeia]

The "long" code would be:

$page = (isset($_GET['page'])) ? $_GET['page'] : "main";

 

$page = '';
if( isset( $_GET['page'] ) ) 
{
    $page = $_GET['page']
}
else
{
    $page = 'main';
}

The "long" code would be:

$page = (isset($_GET['page'])) ? $_GET['page'] : "main";

 

$page = '';
if( isset( $_GET['page'] ) ) 
{
    $page = $_GET['page']
}
else
{
    $page = 'main';
}

 

Ahhh, I get it all now, thanks.
