how can i delete all the records in my mysql table automatically using php?

Question

i am trying to create some code to delete all the records in my mysql table automatically, i have done it in an older projet, but in this case, when i use the exact same script it does not work. i am trying to make it delete after 60 seconds just for testing but i must be doing something wrong.

all the help is much apreciated

my code:

<?php
    function apaga(){

     $dbconn = mysqli_connect("localhost", "root", "", "fct");

     if($dbconn->connect_error){

         die("Falha ao conectar ao servidor: ".$dbconn->connect_erro);

     }

    $queryselect=$dbconn->query("SELECT * FROM mostra1 ")or die(mysqli_error($dbconn));

    while($row=$queryselect->fetch_assoc()){

        $id=$row['id'];

    $sql= "DELETE * FROM mostra1 WHERE `data` < (NOW() - INTERVAL 60 SECONDS)";


    mysqli_query($dbconn,$sql);

     }
    }

    apaga();

    ?>

    $queryselect=$conexao->query("SELECT * FROM mostra1")or die(mysqli_error($conexao));;

   while($row=$queryselect->fetch_assoc()){

      $id=$row['id'];

      $sql= "DELETE FROM mostra1 WHERE data < (NOW() - INTERVAL 1 MINUTE)";

      mysqli_query($conexao,$sql);
