PHP 2D arrays

[smagdy]

Hi all..

Please how do we create 2D array and make it global in PHP.

thanks in advance

you can create 2D arrays in php by combining 2 or more arrays together:

$arr2d = array(1=>array(2=>'1,2'));

so

$arr2d[1][2]

is 1,2 then. it should be possible to use

$arr2d[2][1] = 'test';

to set values of the array.

this array is automatically global. only if you make this in a function it's not. check variable scope in the php docs for more info.

hakre is spot on. And PHP has a lot of nice features when it comes to multi-dimensional arrays [php.net].
