    It's me again, with for some people here probably an easy thing to code.

    I have this txt file, with in it "tags" with a number value that I need to add up all together.

    The parts in the txt file that I need look like this:
    So. The code needs to read the value after <segment bytes=", and add it all together. (it's always on a new line)
    The times that <segment bytes=" is in the file could be one time or many times!

    Now. How could I do this the best way?
    Any help appreciated!

    Using PHP

    I'm not too sure about the reading bytes part sorry but below is php that will read a file line by line:

    $handle = @fopen("/tmp/inputfile.txt", "r");
    if ($handle) {
    while (!feof($handle)) {
    $buffer = fgets($handle, 4096);
    echo $buffer;

    Might be something like this

    Hello, something I wrote very quickly. Could have bugs, havn't tested yet.


    $fin = @fopen("path to file""r");
    if (
    $fin) {

        while (!
    feof($fin)) {
    $buffer fgets($fin);
            if (
    preg_match('/<segment bytes="(\d+)"/',$buffer,$matched))
    $total += $matched['1'];

    Hi blu3ness,

    This looks good! I'll give it a try later today.

    Thank you
