PHP sum of array elements

In this tutorial, we will code the PHP program to sum the array of elements.

PHP Simple Sum of Array Elements

Here, we will code the PHP program simply to sum the array of elements.

<html>
<body>
<?php
$a=array(5,15,25);
echo array_sum($a);
?>
</body>
</html>

<html>

<body>

<?php

$a=array(5,15,25);

echo array_sum($a);

</body>

</html>

Output 45

PHP Simple Sum of Array Elements

Here, we will code the PHP program to sum the array of elements by using them for a loop.

<html>
<body>
<?php
$series;
$sum=0;
$num=10;
for($series=1;$series<=$num;$series++)
{
$sum= $sum+$series;
echo $series;
}
echo "<br/> sum= : ".$sum;
?>
</body>
</html>

<html>

<body>

<?php

$series;

$sum=0;

$num=10;

for($series=1;$series<=$num;$series++)

{

$sum= $sum+$series;

echo $series;

}

echo "<br/> sum= : ".$sum;

</body>

</html>

Output 12345678910 sum= : 55

PHP Sum of Array Elements with Form Values entered by the User

Here, we will code the PHP program to sum the array of elements by using the form values that will be entered by the user. 1st file: index.php 2nd file: sumaction.php Now, let’s see the code of the first file named as index.php.

<html>
<body>
<form method="POST" action="sumaction.php">
Please enter number for sum<input type="text" name="num"><br/>
<input type="submit" name="sub" value="calculator">
</form>
</body>
</html>

<html>

<body>

Please enter number for sum<input type="text" name="num"><br/>

</form>

</body>

</html>

Now, let’s see the code of the first file named as sumaction.php.

<?php
$my_num = $_POST['num'];
$sum=0; $rem;
for($i=0;$i<=strlen($my_num); $i++)
{
$rem=$my_num%10;
$sum=$sum+$rem;
$my_num=$my_num/10;
}
echo "Sum of digits is $sum";
?>

<?php

$my_num = $_POST['num'];

$sum=0; $rem;

for($i=0;$i<=strlen($my_num); $i++)

{

$rem=$my_num%10;

$sum=$sum+$rem;

$my_num=$my_num/10;

}

echo "Sum of digits is $sum";

Output php sum of array elements

PHP Sum of digits

Here, we will code the PHP program to sum all digits of a number. For example, if the number is 234, then it will ad the numbers as 2+3+4=9.

<html>
<body>
</body>
</html>
<?php
$num=134;
$sum=0; $rem;
for($i=0;$i<=strlen($num); $i++)
{
$rem=$num%10;
$sum=$sum+$rem;
$num=$num/10;
}
echo "Sum of digits 134 is $sum";
?>

<html>

<body>

</body>

</html>

<?php

$num=134;

$sum=0; $rem;

for($i=0;$i<=strlen($num); $i++)

{

$rem=$num%10;

$sum=$sum+$rem;

$num=$num/10;

}

echo "Sum of digits 134 is $sum";

Output Sum of digits 134 is 8
