Displaying Images Retrieved with file_get_contents in PHP

In PHP, you can retrieve remote images using the file_get_contents function. However, to display these images on a web page, you need to take additional steps.

Solution:

You can use PHP's readfile() function to output the image directly to the browser. Before doing this, you need to set the correct image headers using getimagesize().

<code class="php"><?php

$remoteImage = "http://www.example.com/gifs/logo.gif";

// Get image information
$imginfo = getimagesize($remoteImage);

// Set image headers
header("Content-type: {$imginfo['mime']}");

// Output the image to the browser
readfile($remoteImage);
?></code>

Explanation:

getimagesize() retrieves the image's size and mime type.

header() sets the necessary image headers, such as the Content-type, which specifies the image's type (e.g., "image/gif").

readfile() outputs the image directly to the output buffer, reducing memory consumption compared to using file_get_contents.
