我需要有关上述标题的建议.我有以下代码:

PHP:

$sql = "SELECT * FROM i_case";
$qry = pg_query($connection, $sql);
$res = pg_num_rows($qry);   

$sql_1 = "SELECT * FROM i_case";
$qry_1 = pg_query($connection, $sql_1);
$res_1 = pg_num_rows($qry_1);

do {
    echo "new record on i_case";
} while($res !=  $res_1 and !(usleep(10000)));

JQUERY:

setInterval(function(){    
    $.ajax({
        type : "POST",
        url : "file.php",
        success : function(response){
            alert(response);
        }
    });
},1000);

这不是我期待的工作.

我不知道代码在哪里？
