从PHP调用MongoDB脚本

我有如下的mongodb脚本

function getSalaryByTitle(){
 var db = connect('TestMongoDB');
 var titles = db.titles.find({},{emp_no:1, title:1});
 var titles_detail = titles.next();
 var salaries = db.salaries.find({emp_no:{ $in: titles_detail } });
 var jsonArr = [];
 while (salaries.hasNext()){
   var salary_detail = salaries.next();
   var title = titles.next();
   jsonArr.push({
      title: title['title'],
      salary: salary_detail['salary']
  }); 
 }
 return jsonArr;
}

如何从php调用它？有人能帮我吗

提前感谢..

与其尝试从PHP调用JavaScript，不如将其转换为本机代码。
