I'm trying to display a php page using javascript with express functions. An example code:
var express = require('express')
var app = express()
app.get('/', function (req, res) {
res.send('Hello World!')
})
var server = app.listen(3000, function () {
var host = server.address().address
var port = server.address().port
console.log('Example app listening at http://%s:%s', host, port)
})
I have a php page with html and javascript functions that displays different data from database and I'm not sure how to call the page from the javascript file. I tried putting it in script tags on the php page but how do I then execute the output of the php page in the res.send();
You're getting things wrong. You can't load your express code into your PHP or vice versa (in fact you can, but it would be too much work).
To make your PHP code talk to your express/node code, you should create an interface between them. I think a RESTful interface would be the easiest one to build. The code you've provided is already a RESTful interface.
Then, in your PHP code (alongside with HTML and client-side JavaScript), you can
res.json({hello: 'Hello World'})
. More about Express json response here ). EDIT: Ok, here is some PHP code:
<?php
$url = "localhost:3000/"; // this should the route you've defined on
// express. the `app.get('/')` part.
$json = file_get_contents($url);
var_dump(json_decode($json));
?>
And your express code should be like:
app.get('/', function(req, res){
res.json({hello: 'Hello World'})
})
Then, your PHP's var_dump
should output:
{hello: 'Hello World'}
