PHP $_POST submission form Chinese garbled problem

PHP $_POST submission form garbled solution is to add "echo ' in the head of the code ';" can solve the problem of garbled submitted data.

Problem details:

Set the header on the submission page<meta charset="UTF-8 ">, and make sure that the editor saves the utf-8 display page and also adds the html header.

echo &#39;<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">&#39;;

Solution:

The front-end calls the interface, and the back-end receives the data and saves the database. Note that contentType must be set like this:

 if(isSuccess){
               var token = sessionStorage.token;
               $.ajax({
                   type:'post',
                   url:'../../api/container/'+token+'/addContainerDamageReport',
                   contentType:'application/x-www-form-urlencoded;charset=utf-8',
                   data:{'containerName':'HJSY'+containerName,'username':username,'description':descript,'damageTime':damageTime
                        ,'reportTime':reportTime,'damageLevel':badLevel,'damageType':badType},
                   cache:false,
                   dataType:'json',
                   success:function(data){
                    $('#submit').attr('data-dismiss',"modal");
                        console.log(data)
                   }
               })
           }

The backend accepts: The encoding format of the page is utf-8, and the SQL server database is gbk. Pay attention to the conversion, otherwise the insertion will be garbled.
