php - 如何将数组值拆分为新数组？

Question

如何将接收到的数组值拆分为新数组？

所以从这里：

[["+","+","+"],["-","+","+"],["*","+","+"],["\/","+","+"],

对此：

["+"],["+"],["+"],["-"],["+"],["+"],["*"],["+"],["+"],

有人能帮我吗？

Answer 1

通过循环来展平你的数组

$aFlattened = array();
foreach($aOriginalArray AS $aOperators){
   $aFlattened = array_merge($aFlattened, $aOperators);
}
