Question

I have an array, which contains data as follows:

 Array (
[google.com] => Array
    (
        [youseo.com] => 1,
        [seo.com] => 1,
        [linkbuilding.com] => 0,
        [seo556.com] => 1,
    )

[youtube.com] => Array
    (
        [youseo.com] => 0,
        [seo.com] => 0,
        [linkbuilding.com] => 0,
        [seo556.com] => 1,
    )

[facebook.com] => Array
    (
        [youseo.com] => 0,
        [seo.com] => 1,
        [linkbuilding.com] => 1,
        [seo556.com] => 0,
    )
  )

And I need to populate new array and count value of url:

Array 
 (
 [google.com] => 3
 [youtube.com] => 1
 [facebook.com] => 2
 )

Please any help for this?

Answer 1

You could use array_values and array_sum:

$counts = array();
foreach ($array as $page_name => $record)
    $counts[$page_name] = array_sum(array_values($record));

But that’s assuming the values can only be 0 or 1.
