fetch api (GET DATA) from php file

Question

I am trying to fetch values from php file

api.php

      <?php
      // want to fetch this value 
      $a = 'come!! fetch this value';

      ?>

my javascript page has code like this.(this code is not on page api.php)

            fetch('http://localhost/react_task/react-webpack-boilerplate/php/api.php', {
        method: 'get',
        // may be some code of fetching comes here
    }).then(function(response) {
            if (response.status >= 200 && response.status < 300) {
                return response.text()
            }
            throw new Error(response.statusText)
        })
        .then(function(response) {
            console.log(response);
        })

can you please guide me how to fetch value of variable from php file by using fetch.

Simple. In your PHP page, put echo $a; at the end. Then when you fetch the page, it will grab the text content of the page, which is what you echo'ed. — RK.

You are not echoing the value, so it won't be send.

<?php
// want to fetch this value 
$a = 'come!! fetch this value';
echo $a;
?>

if i echo the value .. then definitely it will echo..... that is right .... but i want to see value of $a on javascript page not on api page.

That's not possible, the only thing JavaScript can see is what's been echoed by PHP or what's is served by the webserver.

Can you maybe explain a bit more about it? For now it looks like you need some kind of authentication?

Your php needs to output the value you want. A simple way to do this is to use echo. For example:

echo 'come!! fetch this value';

You should use echo to display it in php then it will be available in you JavaScript reponse.
