如何在preg_split（PHP）中的一對第二分隔符內停止分割？

Question

我需要用preg_split生成一個數組，因爲implode('', $array)可以重新生成原始字符串。 `的

$str = 'this is a test "some quotations is her" and more'; 
$array = preg_split('/(|".*?")/', $str, -1, PREG_SPLIT_DELIM_CAPTURE); 

使preg_split生成的

Array 
(
    [0] => this 
    [1] => 
    [2] => is 
    [3] => 
    [4] => a 
    [5] => 
    [6] => test 
    [7] => 
    [8] => 
    [9] => "some quotations is here" 
    [10] => 
    [11] => 
    [12] => and 
    [13] => 
    [14] => more 
) 

我需要的空間的護理之前/引號太后，生成與所述原始字符串的具體圖案的陣列的陣列。

例如，如果該字符串是test "some quotations is here"and，陣列應該是

Array 
(
     [0] => test 
     [1] => 
     [2] => "some quotations is here" 
     [3] => and 
) 

注：基於與@mikel初始討論編輯已經取得進展。

Answer 1

這是否適合您？

preg_split('/(?".*?" ?|)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE); 

Answer 2

這應該做的伎倆

$str = 'this is a test "some quotations is her" and more'; 
$result = preg_split('/(?:("[^"]+")|\b)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE); 
$result = array_slice($result, 1,-1); 

輸出

Array 
(
    [0] => this 
    [1] => 
    [2] => is 
    [3] => 
    [4] => a 
    [5] => 
    [6] => test 
    [7] => 
    [8] => "some quotations is her" 
    [9] => 
    [10] => and 
    [11] => 
    [12] => more 
) 

重建

implode('', $result); 
// => this is a test "some quotations is her" and more
