解析 AJAX 和 php 文件之间的 JSON 数据

Question

So I am running into an issue with my project. I have two files im running which are admin.php and register.php . When I run these files locally I get no issues. Basically I validate the form in my admin file which returns JSON data to the register file. The only issue is, when I run my project on a VPS my register page no longer reads exported JSON data from my admin page and I can't figure out why.

Below are snipets of code | Admin.php

    $status = array("status"=>2,"msg"=>"Email already exist.");
    return json_encode($status, JSON_FORCE_OBJECT);
    exit;

Register.php

           $.ajax({
                url:'./chat/ajax.php?action=create_account',
                data: new FormData($(this)[0]),
                cache: false,
                contentType: false,
                processData: false,
                method: 'POST',
                type: 'POST',
                error:err=>{
                    console.log(err)
                },
                success:function(resp){
                    resp = JSON.parse(resp)
                    var newdata = data.status;
                    console.log(resp);
                    if(newdata == 1){
                            location.replace('login.php')
                    }else{
                        console.log(resp[status]);
                        $('#msg').html("<div class='alert alert-danger'>Caught Error</div>")
                        end_load()
                    }
                }
            })

Answer 1

You can try echo on admin.php like below code

$status = array("status"=>2,"msg"=>"Email already exist.");
echo json_encode($status, JSON_FORCE_OBJECT);
exit;

Answer 2

Maybe it's due to lack of php json extension in the vps that you're using. Install this extension. You can see https://www.php.net/manual/en/json.installation.php for more info
