How to store JSON string in MySQL db

Question

I\'m storing JSON data in a MySQL table using the code below. It works fine if the JSON is short but breaks for longer text. The \"field_json\" is a LONGTEXT.

try this

    $json_string = mysql_real_escape_string( $json_string );
    $sql = sprintf("UPDATE mytable 
    SET field_json = '$json_string'
    WHERE id = $userid");
    $result = mysql_query($sql);
