移动var时，奇怪的浮动到int

Question

Here's my code, fetch_data.php returns a float (an exchange rate). The first echo will return the float that I need (0.65 something) but the second one will return an integer (1)... Why? How do I fix this?

I'm using include because file_get_contents returned PHP for some reason? I don't have a lot of PHP experience and haven't written a line in a month so I'm rusty.

        <div class="callout panel">
          <p><strong>We sell for:</strong> $<?php  

          $coin_price = include('fetch_data.php'); 
          $doge = $coin_price;


          echo $coin_price;  
          echo $doge;

          ?> per 1000</p>
        </div>  

fetch data

    $string = strip_tags($element); //<strong>$484.66</strong>
    $string = str_replace('$', '', $string);
    $int = $string;

    $val = $int * 1.25;

    echo $val / 1000;

any help appreciated

You can use

$doge = floatval($coin_price);
