In PHP, The json_encode does not automatically escape the slash "/".

Preface

Recently, when I saved the crawling link to the mysql database, I found that when I saved the link using json_encode, it showed escape characters in the database, and I didn't need this escape character, it looks unclear and occupies storage space.

Then it is found that, by default, the json format conversion using json_encode will automatically escape the string containing the slash in the data, but sometimes we do not need to escape them. This article describes how to use json_encode without automatically escaping the slash.

For the following array $ a, there are two solutions:

$ A = array ('HTTP: // www.baidu.com ', 'HTTP: // www.baidu.com: // www.baidu.com ');

First, regular expression replacement:

$ A = str_replace ("\/", "/", json_encode ($ a); var_dump ($ );

Second, if the php version is 5.4 or later:

Var_dump (json_encode ($ a, JSON_UNESCAPED_SLASHES ));
