PHP數組格式化（轉換成一個陣列到另一個陣列）

Question

我在PHP類似如下

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 
     ) 

) 

我怎麼能轉換成以下格式的數組。

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

Answer 1

檢查

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

Answer 2

這將很好地工作：

$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);
