If you looking for a solution to find the File Content-Type or MIME Type.
Detecting MIME Type of each file extension is necessary to build dynamic file processing in PHP
Example:
// In the following code image/png is MIME type which is assigned dynamically
header("Content-Type:image/png");
We can get MIME Type using the following simple php code
Here is the best solution to find the Exact MIME Type of the file using the following simple upload form.
<?php
session_start();
if(isset($_POST['upload']))
{
$mime_type = $_FILES['upload_file']['type'];
$_SESSION['mime_type'][] = $mime_type;
}
?>
