Question

$MAX_FILENAME_LENGTH = 260;
$file_name = $_FILES[$upload_name][\'name\'];
//echo \"testing-\".$file_name.\"
\";
//$file_name = strtolower         


        

Answer 1

First, you will have to store the value in a variable like this

$value = explode("/", $string);

Then you can use the end function to get the last index from an array like this

echo end($value);

I hope it will work for you.
