Question

So I have this issue when converting a JSON string to a PHP array. The data is sent via HTTP POST so I'm aware there may be some decoding needed.

Could anyone lay an insight on how I would use json_decode() in PHP to convert this string to an array? "[[\"37\",\"text\",\"\\\"\\\"\"],[\"38\",\"text\",\"\\\"\\\"\"],[\"39\",\"text\",\"\\\"one word two words. Hello? \\\\\\\"escape\\\\\\\" lol\\\"\"]]"

The input was:

[
    ["37", "text", ""],
    ["38", "text", ""],
    ["39", "text", userInputtedString]
]

Where userInputtedString is: one word two words. Hello? "escape" lol

^ Or any other Unicode values

Answer 1

什么似乎是问题？

只需像你提到的那样使用json_decode。

$ans = json_decode($_POST["name-of-var"]);

这应该这样做。

Answer 2

你也可以使用uft8_encode（发送到HTML）和uft8_decode（接收）但不是正确的方式

Answer 3

在json_decode之前使用utf8_encode

$str = "[[\"37\",\"text\",\"\\\"\\\"\"],[\"38\",\"text\",\"\\\"\\\"\"],[\"39\",\"text\",\"\\\"one word two words. Hello? \\\\\\\"escape\\\\\\\" lol\\\"\"]]";
$str = utf8_encode($str);
$str = json_decode($str,JSON_UNESCAPED_SLASHES);
