There are 3 arrays:

$name = array('foo','bar'); $os = array('win','linux'); $arch = array('x86','x64');

How many different combinations (arrays) can I get?

We count: $ name (2 pieces) * $ os (2 pieces) * $ arch (2 pieces) = 8 options

We look at the tree:

In the final version you need to get:

 $graph = array( array('foo', 'win', 'x86'), array('foo', 'win', 'x64'), array('foo', 'linux', 'x86'), array('foo', 'linux', 'x64'), array('bar', 'win', 'x86'), array('bar', 'win', 'x64'), array('bar', 'linux', 'x86'), array('bar', 'linux', 'x64') );

How can such an array be implemented in PHP?

     $name = array('foo','bar'); $os = array('win','linux'); $arch = array('x86','x64'); $result = array(); foreach ($name as $name_value) { foreach ($os as $os_value) { foreach ($arch as $arch_value) { $result[] = array($name_value, $os_value, $arch_value); } } }
