Converting Boolean values inside array into if statement - php

Question

What is the best way to convert array values in to if statement. The array values should be compared by AND and the arrays by OR. I can do this using EVAL but looking for something other than EVAL.
$arr = Array(
[0] => Array
(
[0] => false
[1] => true
)
[1] => Array
(
[0] => true
[1] => false
)
[2] => Array
(
[0] => false
)
[3] => Array
(
[0] => true
)
[4] => Array
(
[0] => true,
[1] => true,
[2] => true
)
)
I want to build comparison dynamically for if statement..
For example
if( ($arr[0][0] && $arr[0][1]) || ($arr[1][0] && $arr[1][1]) .... and so on )

Answer 1

$result = array_reduce($arr, function ($result, array $values) {
return $result || array_reduce($values, function ($result, $value) {
return $result && $value;
}, true);
}, false);
if ($result) ...
One array_reduce can elegantly do this for one array, you simply want to do it for two nested array levels.

Answer 2

What you are doing is generating a single boolean from values in an array. This is known as reduce operation. In php, we can do this with array_reduce(..).
array_reduce($input,
function($prev, $item) {
//Short-circuit if we already deduced it to be true
if($prev) {
return $prev;
}
//If one value is false, the entire thing is false
foreach($item as $k => $v) {
if(!$v) {
return false;
}
}
//All were true
return true;
}, false);
