php array formatting ( convert an array in to another array)

Question

I have an array in php like the following

Array
(
    [0] => Array
        (
            [0] => 0
            [1] => 4
        )

    [1] => Array
        (
            [0] => 5
            [1] => 0
        )

    [2] => Array
        (
            [0] => 0
            [1] => 8
        )

     [3] => Array
        (
            [0] => 10
            [1] => 27
        )

)

How can I convert it into the following format.

array(0,4,5,0,0,8,10,27);

Answer 1

check

foreach($mainarray as $s){
    foreach ($s as $v){
        $str .=$v.','; 
    }
}
echo $str;

Answer 2

This will work fine:

$array = array(array(1, 4), array(5, 0), array(0, 8), array(10, 27));

$result = array();

foreach ($array as $val)
{
  $result = array_merge($result, $val);
}

print_r($result);
