Node.js get value from php

Question

I'm coding a discord bot and I want to get the text of my bot's status from my database so I created a PHP file

<?php

$servername = "xxx.xxx.xxx.xxx";
$dbusername = "root";
$dbpassword = "xxxxxxx";
$dbname = "bot";

$conn = mysqli_connect($servername, $dbusername, $dbpassword, $dbname);
mysqli_set_charset($conn, "utf8");

$username = "phph";

$query = "SELECT text FROM bot WHERE username = '$username'";
$result = mysqli_query($conn, $query);


while($row = mysqli_fetch_array($result)){
   $text = $row['text'];
}

echo $text;

?>

I get the echo of $text when I execute the PHP file with XAMPP

now I want to know that how can I get the value of $text from PHP to JavaScript

help me please ;(

Answer 1

One of the most important programmer skills is the division of complex problems into small parts.

I understood that in your case you have php application that returns text on execution and you need to get this text in node js.

So if you run:

$ php app.php

you will see:

some text of Discord message

and you want to import this text into a variable in node js.

There are two possibilities:

1. Get this text on start on node js program

Then create app.js with

console.log(process.argv[2])

And type

$ node app.js example

You will see example so example can be accessed as process.argv[2]

So it is enough to type

$ node app.js `php app.php`

to have access to some text of Discord message

2. You can want to use php script output in node js when node js process runs.

In this case, read docs of child process

• https://nodejs.org/api/child_process.html
• https://dzone.com/articles/understanding-execfile-spawn-exec-and-fork-in-node
• https://stackabuse.com/executing-shell-commands-with-node-js/
• https://www.freecodecamp.org/news/node-js-child-processes-everything-you-need-to-know-e69498fe970a/

and in the future please divide your problem into smaller pieces like in this case:

"How to get the result of the command in node js"

without the context of discord, php and Xampp.
