Passing data from PHP/HTML to .vue Component

问题

What I'm trying to do is seemingly simple, but I can't seem to figure it out. Basically, I have 2 files:

A PHP file with the following:

...
<user-panel v-if="user.id  && loaded" v-bind:user="user" v-bind:name="theUserName"></user-panel>
...

A .Vue component file with the following (that gets compiled into another file):

<template>
    <span id="userPanel" class="d-flex align-items-center">
        <a href="#" role="button" class="user-dropdown-toggle">
            <div class="logged-in d-flex align-items-center">
                <span class="d-flex align-items-center justify-contnet-center"></span>
                {{name}}
            </div>
        </a>
    </span>
</template>

<script>
    export default {
        name: "UserPanel",
        props: ['user'],
        created () {
            console.log(this.$refs.myTestField.value)
        }
    }
</script>

All I'd like to do is pass data from the PHP to Vue into {{name}}. I've tried v-bind, a data-attribute, a hidden input, etc. Any help would be greatly appreciated.

Vue single file components are processed on client side.

There are SSR, however, since you have php on your server, you must set up a REST service so you can use fetch or axios to consume server data and present it to the client side.

Let's say you have a php variable that contains string. $phpString

PHP file

...
<my-component v-bind:myProperty="<?php echo $phpString ?>"></my-component>
...

^{Don't forget to escape $phpString before echoing it.}

In your Vue define a property called myProperty:

<template>
  <span>
    {{ myProperty }}
  </span>
</template>

<script>
export default {
  props: ['myProperty']
}
</script>

My intention is to transfer data from my .php file to the .js file where the VUE code resides. Here I show you my code. In the proposed example I would like to import a simple string, subsequently I would like to import a JSON. Thank you so much. File PHP

<div id='app'> <App v-bind:import='Value Import'> C'è QUALCHE PROBLEMA </App> </div>"

File .js

var App = Vue.component("App", {
    template: `
      <div class="container">
        <div>
          <h2>{{ titolo }}</h2>
          <h3>{{ import }}</h3>

        </div>
      </div>
    `,
    props: ['import'],

    data() {
      return {
        color: "color: red",
        titolo: "Inizio Container",
      };
    }
  });

  new Vue({
    el: "#app",
  });

Quanto sopra purtroppo non funziona.
