如何将带有反斜杠的php字符串转换为json数组

Question

我想用php

生成这个JSON数组

select
  max(case when AccountCode = 1000 then case when TransactionType = 'Debit' then Amount end else case when AccountCode = 1000 then case when TransactionType = 'Credit' then Amount*-1 end) [Total Transaction Premium]
  max(case when AccountCode = 1000 then case when TransactionType = 'Debit' then Amount end else case when AccountCode = 1000 then case when TransactionType = 'Credit' then Amount*-1 end) [Total Transaction Premium]
from PolicyTransactionSplits
where PolicyTransactionId = 10

但如果我使用此代码：

{"to": "/topics/foo-bar"}

它正在返回

  

{“to”：“/ topics / foo-bar”}

我尝试了$topic = "/topics/foo-bar"; $g_topic= array( 'to' => $topic ); echo json_encode($g_topic ); ，stripslashes()，但没有一种方法可以使用

Answer 1

就在the manual for the json_encode() function：

echo json_encode($g_topic, JSON_UNESCAPED_SLASHES);

将产生：

{"to": "/topics/foo-bar"}

Answer 2

你需要像这样回应它。

$topic = "/topics/foo-bar";
$g_topic= array(
            'to' => $topic
        );
echo json_encode($g_topic, JSON_UNESCAPED_SLASHES), "\n";
