A function of PHP escaping special characters in JSON

Make an API for an App, pull the data from the server-side MySQL, and then generate the JSON. 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:

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

It must be converted to:

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 Function escapejsonstring ($value) {$escapers = array ("\ \", "/ "," \ "", "\ n", "\ r", "\ T", "\x08", "\x0c"); $replacements = Array ("\\\\", "\\/", "\\\", "\\n", "\\r", "\\t", "\\f", "\\b") ; $result = Str_replace ($escapers, $replacements, $value); return $result;}

Often use, record, hope to help you.
