Question

I am fetching some information from mysql database and I am displaying it using the following script(I am using Codeigniter)

 <?php if(count($records) > 0) { ?>

   <?php $i = $this->uri->segment(3) + 0; foreach ($records as $row){ $i++; ?>
<?php echo $row['amount']; ?>    <br>

<?php  } ?>

<?php } else { echo "No Record Found";} ?>

The out put I get is like following

10,000
20,000.34
15,250.50

Now what I am trying to do is sum up all the values that are in $row['amount']; and put the value of the summation in $sum_value so that when I echo $sum_value I get the following value

45,250.84

Would you please kindly show me how to do it.

I know I could have done the summation things using mysql, but I want to learn how to do this way.

Thanks in Advance 🙂

Iteratively add to your sum with each loop through the foreach:

$sum = 0;
foreach ( $records as $row ) {
  $sum += str_replace(",", "", $row['amount']);
}

echo number_format( $sum, 2 );
