How do I build a complex array in PHP?

How can I build an array like this in PHP?

It should have unique keys each of whose corresponding values are arrays, and those arrays have multiple elements for each key.




Array (

    42 => Array ( 56, 86, 97 )

    51 => Array ( 64, 52 )

)

$main = array();
for ($i=0; $i<10; $i++) {
// $i makes numeric keys
$main[$i] = array();

// Or instead, you could make a truly unique key name for each:
$main[uniqid()] = array(...somevalues...);

}

Creates something like:

Array
(
[4f105f361cdd1] => Array
(
)

[4f105f361cf24] => Array
(
)

[4f105f361cf33] => Array
(
)

[4f105f361cf3c] => Array
(
)

[4f105f361cf44] => Array
(
)

)

$arr = array(
42 => array(56, 86, 97),
51 => array(64, 52)
);

var_dump($arr);
