PHP：使用不同的分隔符列表拆分字符串，并保留有关分隔符的信息

这实际上是两个问题的一种组合，我面临着这两个问题，但没有找到解决办法

假设分隔符数组是

$splitby = array('dlmtr1','dlmtr2','dlmtr3',' ','dlmtr5','dlmtr6');

$text = '  dlmtr1This is     the string dlmtr2dlmtr2TTTdlmtr5WWWWW ';


$textArr = ('This', 'is', 'the', 'string', 'TTT', 'WWWWW');

$delimiterArr = ('  dlmtr1', ' ', '     ', ' ', 'dlmtr2dlmtr2', 'dlmtr5',' ');

换言之，这是真的

$text == $delimiterArr[0] . $textArr[0] . $delimiterArr[1] . $textArr[1] . ... . $delimiterArr(count($delimiterArr));

因此，

$delimiterArr

的每个项目至少包含一个或多个分隔符，如您所见

模式的可能解决方案步骤如下：

$pattern = '/\s?'.implode($splitby, '\s?|\s?').'\s?/';

然后我会以任何方式得到错误的结果

更新：这是我得到的接近预期结果的结果，但问题是分隔符被拆分，但如果它们在文本中在一起，它们应该在一起**

$splitby = array('dlmtr1','dlmtr2','dlmtr3',' ','dlmtr5','dlmtr6');
$text = '  dlmtr1This is     the string dlmtr2dlmtr2TTTdlmtr5WWWWW ';

$pattern = '/\s?'.implode($splitby, '\s?|\s?').'\s?/';
$result = preg_split($pattern, $text, -1, PREG_SPLIT_NO_EMPTY);
preg_match_all($pattern, $text, $matches);
print_r($result);
print_r($matches[0]);

结果：

Array
(
    [0] => This
    [1] => is
    [2] => the
    [3] => string
    [4] => TTT
    [5] => WWWWW
)
Array
(
    [0] =>   
    [1] => dlmtr1 '[0] and [1] should come together
    [2] =>  
    [3] =>    
    [4] =>   
    [5] =>  
    [6] =>  dlmtr2 '[6] and [7] should come together
    [7] => dlmtr2
    [8] => dlmtr5
    [9] =>  
)

谢谢。

下面的代码按预期运行

$splitby = array('dlmtr1','dlmtr2','dlmtr3',' ','dlmtr5','dlmtr6');
$text = '  dlmtr1This is     the string dlmtr2dlmtr2TTTdlmtr5WWWWW ';

preg_match_all("/\s*(dlmtr[1-6])+\s*|\s+/", $text, $matches);
echo "<pre>";print_r($matches[0]);echo "</pre>";

Array
(
    [0] =>   dlmtr1
    [1] =>  
    [2] =>      
    [3] =>  
    [4] =>  dlmtr2dlmtr2
    [5] => dlmtr5
    [6] =>  
)

$result = explode(' ', trim(preg_replace("/\s*(dlmtr[0-9])+\s*|\s+/",' ', $text)));
echo "<pre>";print_r($result);echo "</pre>";

Array
(
    [0] => This
    [1] => is
    [2] => the
    [3] => string
    [4] => TTT
    [5] => WWWWW
)

$splitby=array（'dlmtr1'，'dlmtr2'，'dlmtr3'，''，'dlmtr5'，'dlmtr6'）；
$text='dlmtr1这是字符串dlmtr2dlmtr2TTTdlmtr5WWWWW'；
preg_match_all（“/\s*（dlmtr[1-6]）+\s*|\s+/”，$text，$matches）；
回声“；打印（$matches[0]）；回声“；
排列
(
[0]=>dlmtr1
[1] =>  
[2] =>      
[3] =>  
[4] =>dlmtr2dlmtr2
[5] =>dlmtr5
[6] =>  
)
$result=explode（“”，trim（preg_replace（“/\s*（dlmtr[0-9]）+\s*|\s+/”，“”，$text））；
回声“；打印（结果）；回声“；
排列
(
[0]=>此
[1] =>是
[2] =>
[3] =>字符串
[4] =>TTT
[5] =>WWWWW
)
