Answer 1

 preg_match_all("/(\d{10})[\s|$]/", $string, $output);

 var_dump($output);

Preg_match_all will search all lines of $string and look for numbers \\d that is 10 digits long {10} and make sure there is a space or end of string after the digits [\\s|$] to make sure it's not a 11 digit number.

output of above code:

array(2
    0=>array(8
            0 => 7045693328 
            1 => 9819286096 
            2 => 9833329668 
            3 => 9822965734 
            4 => 9075613876 
            5 => 9822965734 
            6 => 9403358204 
            7 => 8691955808 
    )
    1=>array(8
            0 => 7045693328
            1 => 9819286096
            2 => 9833329668
            3 => 9822965734
            4 => 9075613876
            5 => 9822965734
            6 => 9403358204
            7 => 8691955808
    )
)
