如果您从php成功调用SAS存储过程，那么您只需要从javascript异步调用您的php服务。

$.ajax({
    type: "POST",
    url: url + '&_action=background',
    data: data, // additional parameters 
    async:true,
    success: function(response){  
     alert(response); 
     // all code here will execute AFTER the PHP/STP is finished
    }
});
// all code here will execute immediately

编辑：按照@quentin的建议，在URL中添加_action=background

AJAX 应该可以正常工作！你甚至可以尝试使用SASjs javascript library。更多关于website的细节。示例代码-一旦配置-如下所示：

var adapter = new SASjs.default({
     appLoc: "/SASFolder/appLocation"
    ,serverType:"SAS9"
}); // Can be SAS9 or Viya

var dataObj = {tableName: [{ colName: 'colValue' }]}; // can be null
adapter.request('/subfolder/servicename',dataObj)
.then((response) => {
  //we just submitted a request, now deal with response
  alert(response);
  // all code here will execute AFTER the STP / JES is finished
});
// all code here will execute immediately
