How to Build a JSON Array from a MySQL Database for Fullcalendar?

Building a JSON Array from a MySQL Database

To construct a JSON array from a MySQL database, it is essential to understand the specific format required. In this case, the array must conform to the structure employed by the fullcalendar library for displaying dynamic events on a calendar.

To address this issue, you can leverage PHP to retrieve data from the database and assemble the array. The example provided in the code snippet demonstrates this approach, wherein a $return_arr array is populated by iteratively fetching rows from the database using the mysql_query() and mysql_fetch_array() functions.

Each element of the $return_arr array represents a row in the database, with its keys corresponding to the column names. Once the array is complete, the json_encode() function converts it into a JSON string, with each object represented as a pair of curly braces ({}).

Alternatively, you can modify the code to directly populate a JSON array, specified by the $json_array variable, with the desired event data from the database. In this case, the json_encode() function is used to transform the PHP array into a JSON string. Both approaches yield a JSON string suitable for use with fullcalendar, enabling the dynamic display of events on the calendar.
