PHP preg_split具有两个定界符，除非在引号内包含定界符 [英] PHP preg_split with two delimiters unless a delimiter is within quotes
问题描述
从我之前关于> $的问题开始c $ c> preg_split 得益于nick，它的响应速度非常快。我真的很想扩展该方案，以在引号内包含定界符时不拆分字符串。例如：
Further on from my previous question about preg_split which was answers super fast, thanks to nick; I would really like to extend the scenario to no split the string when a delimiter is within quotes. For example:
如果我有字符串 foo = bar AND bar = foo或foobar = foo bar ，我希望在每个空格或 = 字符上拆分字符串，但在返回的数组中包含 = 字符（当前效果很好），但是我不想拆分字符串中的两个分隔符都放在引号内。
If I have the string foo = bar AND bar=foo OR foobar="foo bar", I'd wish to split the sting on every space or = character but include the = character in the returned array (which works great currently), but I don't want to split the string either of the delimiters are within quotes.
到目前为止，我已经知道了：
I've got this so far:
<!doctype html>
<?php
$string = 'foo = bar AND bar=foo';
$array = preg_split('/ +|(=)/', $string, -1, PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
?>
<pre>
<?php
print_r($array);
?>
</pre>
哪个会吸引我：
Array
(
[0] => foo
[1] => =
[2] => bar
[3] => AND
[4] => bar
[5] => =
[6] => foo
)
但是如果我将字符串更改为：
But if I changed the string to:
$string = 'foo = bar AND bar=foo OR foobar = "foo bar"';
我真的希望数组为：
Array
(
[0] => foo
[1] => =
[2] => bar
[3] => AND
[4] => bar
[5] => =
[6] => foo
[6] => OR
[6] => foobar
[6] => =
[6] => "foo bar"
)
注意 foo bar 没有拆分
真的不确定如何在RegEx内执行此操作，或者是否有更好的方法，但是您的所有帮助将不胜感激！
Really not sure how to do this within the RegEx or if there is even a better way but all your help would be very much appreciated!
谢谢大家！
推荐答案
我能够通过添加带引号的字符串作为分隔符a-la来做到这一点
I was able to do this by adding quoted strings as a delimiter a-la
"(.*?)"| +|(=)
引用的部分将被捕获。看来这有点脆弱，我没有对其进行广泛的测试，但这至少可以在您的示例中使用。
The quoted part will be captured. It seems like this is a bit tenuous and I did not test it extensively, but it at least works on your example.
