如何创建一个JSON文件并在Wordpress上读取它

Question

I need to create a JSON file to save a list in it. This code has to go inside the Wordpress functions.php file. How can I do it?

function ProgramarBorrado(){
        ?> 
        <script type="text/javascript">
            var day = (new Date).getDate(); //Get today
            var month = (new Date).getMonth()+1; //Get this month
            var year = (new Date).getFullYear(); //Get this year
            var lista = [];
            if ((day == 1) && (month == 4) && (year==2019)) {  //Push ID on a list
            lista.push('#borrar22marc');
            }
            if ((day == 6) && (month == 4) && (year==2019)) {
            lista.push('#borrar6abril');
            }
            if ((day == 5) && (month == 5) && (year==2019)) {
            lista.push('#borrar5maig');
            }
            if ((day == 19) && (month == 5) && (year==2019)) {
            lista.push('#borrar19maig');
            }
            if ((day == 8) && (month == 6) && (year==2019)) {
            lista.push('#borrar8juny');
            }
            if ((day == 10) && (month == 8) && (year==2019)) {
            lista.push('#borrar10agost');
            }

            lista.forEach(function(element) {
                  jQuery(element).addClass('borrar-programado');// For each element on the list add a class on the ID
                });

        </script>
    <?php
}
add_action('wp_footer', 'ProgramarBorrado');

the code has to be similar to this. Save the variable "lista" on a JSON file

如果数组是在javascript中生成的，则可以使用JSON.stringify

var json = JSON.stringify(lista);
