$_SESSION[][][]

[scuarplex]

Hey, i was reading some code and i find this:

 

if(stristr($_SESSION["s"]["user"]["asdasd"]),$someString)

 

 

How the double/triple [] in $_SESSION works ?

 

PS: I tryied to google it but it was kinda hard to search :X

 

Thanks.

It's the same for any array variable. Use print_r() to print out the array, this will allow you to visualise the structure of it and understand how it works. It's basically arrays within arrays aka a multidimensional array.

<?php 

$a1['level1']['level2'] = 'test';
// is the same as
$a1 = array( 'level1'=>array('level2'=>'test') );

$a2[0][0] = 'test';
// is the same as
$a2 = array( array('test') );

?>

 

Use var_dump or print_r to output/debug the array structure/values;
