There is a field in the data called content, which holds the content of the article, contains a lot of HTML tags, this field should be escaped when the JSON is transferred, because there are a large number of special characters will destroy the structure of the JSON.

Such a content:

1. ' Lorem ipsum ' dolor ' sit amet, consectetur \ adipiscing elit. '

It must be converted to:

1. Lorem ipsum \ "dolor\" sit amet,\nconsectetur \ adipiscing elit.

So what are the characters that need to be escaped? See:

If PHP version > 5.2,json_encode comes with Escape. If you have an older version of PHP, you can use the following function.

#list from www.json.org: (\b Backspace, \f formfeed) Public functionEscapejsonstring ($value) {     $escapers=Array("\ \", "/", "\" "," \ n "," \ r "," \ T "," \x08 "," \x0c "); $replacements=Array("\\\\", "\\/", "\\\" "," \\n "," \\r "," \\t "," \\f "," \\b "); $result=Str_replace($escapers,$replacements,$value); return $result;}
