php - 正则表达式将字符串用引号括起来

Question

我有一个类似于下面示例的数组，但要大得多（4000 行长）：

array(
   "id" => array(
        "a" => "", 
        "b" => "", 
        "c" => Needs Quotes Around Me
), "id" => array(
        "a" => "", 
        "b" => "", 
        "c" => Needs Quotes Around Me
        "d" => Needs Quotes Around Me
)
);

出于某种原因，字符串值没有引号 ("") 和冒号分隔符。有些字符串是数字，但可以被视为字符串，有些有空格和@符号，因为有些是电子邮件地址，但我需要将它们全部包装起来"STRING HERE",

我试图将 reg_replace 与这样的东西一起使用，=>\s([a-zA-Z0-9\@\s])+$但它不会用它找到的字符串替换匹配的字符串？我已经做了很多谷歌搜索，但似乎无法正确，请告诉我我哪里出错了。

我最终得到的是：

array(
       "id" => array(
            "a" => "", 
            "b" => "", 
            "c" => "[a-zA-Z0-9\@\s]",
    ), "id" => array(
            "a" => "", 
            "b" => "", 
            "c" => "[a-zA-Z0-9\@\s]",
            "d" => "[a-zA-Z0-9\@\s]",
    )
);

Answer 1

此 perl 脚本适用于给出的示例

perl -pe 's/(?<==> )(?!"|array\()(.*)/"$1",/' EXAMPLEFILE.txt

产生以下输出：

array(
   "id" => array(
        "a" => "", 
        "b" => "", 
        "c" => "Needs Quotes Around Me",
), "id" => array(
        "a" => "", 
        "b" => "", 
        "c" => "Needs Quotes Around Me",
        "d" => "Needs Quotes Around Me",
)
);

Answer 2

它需要在正则表达式周围放置圆括号。听起来很简单，只有当您知道如何操作时才容易。
