在发一帖，怎么去连接本地数据库进行增删改查，这个URL要怎么填

[qq_31593091]

wx.request({
url: 'http://localhost/WebServiceForMES_Setup/qingqiu.php',
data:
{
name: e.detail.value.name,
age: e.detail.value.age,
gender: e.detail.value.gender
}
,
method: 'POST', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT
header: {
'content-type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
success: function (res) {
var err = res.data.error
if (err) {
_this.setData({
error: err
})
}
else {
wx.redirectTo({
url: 'create_photo'
})
}
},
fail: function () {
// fail
},
complete: function () {
// complete
}
})，附上代码，
<?php
$name=$_GET["name"];
$age=$_GET["age"] ;
$gender=$_GET["gender"];
$conn = mysqli_connect("localhost", "sa", "123","Number");
$sql = "insert hehe values('$name','$age','$gender')";
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_assoc($result)) {
echo json_encode($row);
}
}
?>PHP代码。也可以换其他方式，我要怎么去填写那个URL，怎么才能访问到自己本地的数据库操作
