拆分字符串，同时将定界符和字符串保留在外部 [英] Split a string while keeping delimiters and string outside

问题描述

我正在尝试做一些必须非常简单的事情，但是我对PHP还是陌生的，因此我为此而苦苦挣扎。我想要的是拆分一个包含0、1个或多个定界符（大括号）的字符串，同时将定界符AND字符串与AND字符串之间的字符串保持在外面。

I'm trying to do something that must be really simple, but I'm fairly new to PHP and I'm struggling with this one. What I want is to split a string containing 0, 1 or more delimiters (braces), while keeping the delimiters AND the string between AND the string outside.

ex：'您好{F} {N}，您好吗？'将输出：

ex: 'Hello {F}{N}, how are you?' would output :

Array ( [0] => Hello 
        [1] => {F}
        [2] => {N} 
        [3] => , how are you? ) 

到目前为止，这是我的代码：

Here's my code so far:

$value = 'Hello {F}{N}, how are you?';
$array= preg_split('/[\{\}]/', $value,-1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
print_r($array);

输出（缺少括号）：

Array ( [0] => Hello 
        [1] => F
        [2] => N 
        [3] => , how are you? )

我也尝试过：

preg_match_all('/\{[^}]+\}/', $myValue, $array);

哪个输出（大括号在那里，但外面的文本被刷新了）：

Which outputs (braces are there, but the text outside is flushed) :

Array ( [0] => {F} 
        [1] => {N} ) 

我敢肯定我在使用preg_split时使用的是正则表达式，但是使用了错误的正则表达式。谁能帮我这个？还是告诉我是否要离开？

I'm pretty sure I'm on the good track with preg_split, but with the wrong regex. Can anyone help me with this? Or tell me if I'm way off?

推荐答案

您没有捕获定界符。将它们添加到捕获组：

You aren't capturing the delimiters. Add them to a capturing group:

/(\{.*?\})/
