以更智能的方式使用爆炸

Question

我有以下字符串：

$string = "This is my string, that I would like to explode. But not\, this last part";

我想explode(',', $string)字符串，但当逗号前面有explode()时，\不应该爆炸。

通缉结果：

array(2) {
  [0] => This is my string
  [1] => that I would like to explode. But not , this last part
}

Answer 1

我会使用preg_split()：

$result = preg_split('/(?<!\\\),/', $string);

print_r($result);

(?<!\\\\)是一个外观。因此,前面没有\。需要使用\\\来表示单个\，因为它是转义字符。
