PHP Program to find Average of N Numbers
You are Here:
Using for loop
In the following example, we will find the average of numbers between 1 and 10 using for loop.
Example
PHP Compiler
<?php
$start = 1;
$end = 10;
$total = 0;
$count = ($end - $start) + 1;
$average = 0;
echo "Average of numbers between $start and $end: <br>";
for($start=$start; $start<=$end; $start++)
$total += $start;
echo "<br> Total = $total";
echo "<br> Count = $count";
$average = $total / $count;
echo "<br> Average is $average";
?>
Output
Average of numbers between 1 and 10:
Total = 55
Count = 10
Average is 5.5
Using while loop
In the following example, we will find the average of numbers between 1 and 10 using while loop.
Example
PHP Compiler
<?php
$start = 1;
$end = 10;
$total = 0;
$count = ($end - $start) + 1;
$average = 0;
echo "Average of numbers between $start and $end: <br>";
while($start <= $end)
{
$total += $start;
$start++;
}
echo "<br> Total = $total";
echo "<br> Count = $count";
$average = $total / $count;
echo "<br> Average is $average";
?>
Output
Average of numbers between 1 and 10:
Total = 55
Count = 10
Average is 5.5
Using do while loop
In the following example, we will find the average of numbers between 1 and 10 using do while loop.

}while($start <= $end);
echo "<br> Total = $total";
echo "<br> Count = $count";
