      <?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.

Answer 1

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;
?>

Answer 2

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';

Answer 3

您应该使用 echo 在 php 中显示它，然后它将在您的 JavaScript 响应中可用。
