Subtract eexpense.txt from balance.txt and print result

[mpg]

I Have two txt files I need to read both subtract the difference.

So subtract eexpense from balance and print result.

Cant see to figure it….probably simple, perhaps someone can help.

I have attached both...balance.txt

So if balance.txt is 330 and eexpense.txt is 60 the result is 270

eexpense.txt

What have you tried so far?

[mpg]

just adding the total of either one.

<?php
$lines = file('balance.txt');
echo "Reciveables $" . array_sum($lines) . "\n";
?>

So where is your problem?

[mpg]

I wanted to know how to take both those files and subtract the difference. Stuck there at the moment.

[Barand]

$diff = $total_receivables - $total_expenses;

DOnt laugh this is the best i can come up with.

<?php
$total_receivables = file('balance.txt');
echo "Reciveables $" . array_sum($total_receivables) . "\n";
echo ' | ';
$total_expenses = file('ebalance.txt');
echo "Expenses $" . array_sum($total_expenses) . "\n";

$diff = $total_receivables - $total_expenses;
echo "$diff";
?>

I thought you would have realised in your initial code that you had the total_receivables from your array_sum() function call. If in doubt what a function is doing, there is always the manual

Getting total expenses would be very similar.

Subtracting one from the other is an easy bit.

<?php
$total_receivables = file('balance.txt');
echo "Reciveables $" . array_sum($total_receivables) . "\n";
echo ' | ';
$total_expenses = file('ebalance.txt');
echo "Expenses $" . array_sum($total_expenses) . "\n";

$diff = array_sum($total_receivables) - array_sum($total_expenses);
echo "$diff";
?>

No I didnt but now that you mention it everything works out....DUH.

echo '$' . number_format(array_sum(file('balance.txt')) - array_sum(file('eexpense.txt')), 2);

--> $270.00
