PHP正则表达式：在数值上拆分一个字符串

问题描述：

I have a code that can receive 2 types of string:

text number text
```
danny levitt 48 new york
```
text number [comma] text
```
danny levitt 48, new york
```

The text on both size can be a single word or more, and the language might not be english.

I need those strings to return to me in an array as follows:

    Array (
        0 => "danny levitt",
        1 => "48",
        2 => "new york"
    )

How can I do that?

Thanks.

我有一个代码可以接收两种类型的字符串： p>

文本编号文本 p>

  danny levitt 48 new york 
  code>  pre>  li> 
  文本编号[逗号]文本 p> 
 
 
  danny levitt 48，new york 
  code>  pre>  li> 
  ol> 
 \  n 两个大小的文本都可以是一个单词或更多，语言可能不是英语。 p> 
 
 
我需要这些字符串在数组中返回给我，如下所示：   p> 
 
 
  Array（
 0 =＆gt;“danny levitt”，
 1 =＆gt;“48”，
 2 =＆gt;“new york”
）  
  code>  pre> 
 
 我该怎么做？ p> 
 
 
谢谢。 p> 
  div>

答

Split your input according to the space which exists just before to the number and the space which follows the same number. \K discards the previously matched characters.

$string = "danny levitt 48, new york";
$regex = '~\s+(?=\b\d+,?)|\b\d+\K,?\s+~';
$splits = preg_split($regex, $string);
print_r($splits);

Output:

Array
(
    [0] => danny levitt
    [1] => 48
    [2] => new york
)
