php solution:

function countApplesAndOranges(t, b, oranges) { orange_count = 0;

foreach (`$apples as $`key => $value) {
    `$sum = $`a + $value;
    if( `$sum >= $`s && `$sum <= $`t ){
        $apple_count++;
    }
}

foreach (`$oranges as $`key => $value) {
    `$sum = $`b + $value;
    if( `$sum >= $`s && `$sum <= $`t ){
        $orange_count++;
    }
}

echo `$apple_count."\n".$`orange_count;

}
