我如何使我的php代码无阻塞并在函数执行后继续

Question

我正在尝试运行将执行功能的代码，只是继续循环而不等待执行的功能完成。像这样的东西：

var jobSpec = {
configuration: {
  load: {
    destinationTable: {
      projectId: projectId,
      datasetId: datasetId,
      tableId: tableId
    },
    allowJaggedRows: true,
    writeDisposition: 'WRITE_TRUNCATE',
    allowQuotedNewlines: true,
    schema: {
      fields: [ 
        {name: 'User_id', type: 'STRING'},
        {name: 'Email', type: 'STRING'},
        {name: 'Comments', type: 'STRING'},
         ]
    }
  }
}
};

  var spreadsheet = SpreadsheetApp.openById(fileId);
  var MAX_ROWS = 50000;
   var sheet = spreadsheet.getSheetByName("test");
   var data = sheet.getDataRange().getValues();
   var csvdata = "";
   for (var row = 1; row < data.length && row < MAX_ROWS + 1; row++) {
     for (var col = 0; col < data[row].length; col++) {
      var cell = data[row][col].toString();
      if (cell.indexOf(",") != -1) {
      csvdata += "\"" + cell + "\"";
       } else {
        csvdata += cell;
  }

  if (col < data[row].length - 1) {
    csvdata += ",";
  }
}
csvdata += "\r\n";

}

我不需要processData函数来阻止我的代码。我只想执行它，然后继续其余的代码，因此继续循环。
