将Javascript的for循环索引传递给Javascript中包含的php代码

Question

I am trying to pass the for loop iteration index "i" into a php code that is present inside the javascript loop.

I tried to use ajax call with a post type and then call $_POST['.....']; to read the variable value from inside php. I also tried document.write to read javascript variable directly.

    for (var ik = 0; ik < count; ik++) {
    $.ajax({
    type:"POST",
    url: "new4.php",
    data:"key1=" ik,
    success: function(){//do stuff after the AJAX calls successfully completes

    }
});

    var data = new google.visualization.DataTable();
    data.addColumn('string', 'Shift_Type');
    data.addColumn('number', 'Value');
    data.addRows([//some php code that needs to know the value of ik]);}
