[SOLVED] sum of values in text file

[wkilc]

Hello,

 

If I have an existing file on my server: "tickets.txt"  ...each row contains a single number, such as:

 

1

2

1

2

3

1

 

... is it possible to use PHP to display the sum total of all the rows?  (10, in this case)?

 

Can someone nudge me in the right direction?

 

Thanks.

A simple combination of file and array_sum should do the trick.

Thank you!

 

<?php
$a = array(1, 2, 1, 2, 3, 1);
echo "sum(a) = " . array_sum($a) . "\n";
?>

 

 

I'm not sure how to implement the "file".

 

I'm sorry... could some give me an example?

The manual provides an example.  Follow the link.

  Thank you... I didn't see the links.

 

In case anyone as dumb as me searches this thread one day, here's the solution:

 

<?php
$lines = file('test.txt/');
echo "sum($lines) = " . array_sum($lines) . "\n";
?>
