PHP, read values from txt file, and add

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:

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

Might be something like this

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

PHP:

#!usr/local/bin/php

<?php
$total = 0;

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

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

}
?> 


 

Hi blu3ness,

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

Thank you
