        $this->db->insert('file_upload', $data);

Answer 1

Use getimagesize()

$file // path of the file
$result = getimagesize($file);
$mime = $result["mime"];

Answer 2

Read pathinfo()

<?php
$path_parts = pathinfo('/www/htdocs/inc/inc.php');

echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
echo $path_parts['filename'], "\n"; // since PHP 5.2.0
?>

The above example will output:

/www/htdocs/inc

inc.php

php

inc

Answer 3

pathinfo does this magic for you

 <?php 
    $ext = pathinfo("file.png", PATHINFO_EXTENSION);
    echo $ext ;
    $filename = pathinfo("file.txt", PATHINFO_FILENAME);
    echo "<br/>";
    echo $filename;
    ?>

This is fast, efficient, reliable and built-in. pathinfo() can give you other information, such as canonical path, depending on the constant you pass to it.
