Why this code is not working in Codeigniter, while when I remove base64_encode the code runs perfectly and the same if I use file_get_contents, why both function are not working?

$imagedata = mysql_real_escape_string(base64_encode(file_get_contents($_FILES["userfile"]["tmp_name"])));

Thanks in advance.

    What's your PHP version and what errors do you get? What happens if you do this: `var_dump($_FILES["userfile"]["tmp_name"])`? – Mr.Web Dec 31 '14 at 07:37

mysql_real_escape_string is making error here . These two link will help you to handle this link1 and link2

so please use $this->db->escape($val) instead of mysql_real_escape_string

 <?php
    // <= PHP 5
    $data = file_get_contents($_FILES["userfile"]["tmp_name"], true);
    // > PHP 5
    $data = file_get_contents($_FILES["userfile"]["tmp_name"], FILE_USE_INCLUDE_PATH);
    ?>

$_FILES["userfile"]["tmp_name"] produce file name like 

<?php
// <= PHP 5
 $data = $this->db->escape(base64_encode(file_get_contents("test/faruk.txt", true)));
// > PHP 5
 $data = $this->db->escape(base64_encode(file_get_contents("test/faruk.txt", FILE_USE_INCLUDE_PATH)));
echo $data; 
?>

and my output is SGVsbG8gd29ybGQxNDEyMTYyMTYx for content "Hello world1412162161"
