PHP Jsonp single quote Escape _php instance

The JSONP output in PHP is generally in the following format:

Copy Code code as follows:

Callbackname (' JSON string ');

If the middle JSON string contains single quotes, the output is problematic and the caller is generally not able to handle it, so we have to escape the single quotation marks.

If it is generated in json_encode, it can be escaped in the following way:

Copy Code code as follows:

$ret = Json_encode ($result, Json_hex_apos);
Header (' Content-type:text/javascript; Charset=utf-8 ');
Echo $callback. ' (\ '. $ret. '\');';

Here Json_hex_apos is provided by PHP to swap single quotes for \u0027.

If the string is spliced, you can use the following method:

Copy Code code as follows:

$jsonData = preg_replace ('/\ '/', ' \u0027 ', $jsonData);

and then output.
