How to calculate sum of array in php?

I have two arrays with this structure

array1 = Array(0=>Array(4, 7, 0, 11), 1=> Array(5,7,6,18)); array2 = Array(0=>Array(5,1,7,13), 1=>Array(9,1,6,16)); 

I tried to calculate sum of this array by element like this => 4 + 5 = 9;

Array(0=>Array(9,8,7,24), 1=>Array(14, 8, 12, 34)); 

$array1 = [[4, 7, 0, 11], [5, 7, 6, 18]]; $array2 = [[5, 1, 7, 13], [9, 1, 6, 16]]; $output = array_map(function($a, $b)< return array_map(function() < return array_sum(func_get_args()); >, $a, $b); >, $array1, $array2); var_dump($output); 

array (size=2) 0 => array (size=4) 0 => int 9 1 => int 8 2 => int 7 3 => int 24 1 => array (size=4) 0 => int 14 1 => int 8 2 => int 12 3 => int 34

Find the sum of value from array

I have a cart table and wish to calculate sum of cost wherever I have status=1

id cost status 1 10 1 2 10 1 2 10 1 2 10 2 

$sql01 = "SELECT * FROM cart where status='1' "; $result01 = mysqli_query($con, $sql01); if (mysqli_num_rows($result01) > 0) < while($row = mysqli_fetch_assoc($result01)) < $price = array_sum($row); echo "sum of cod:"; echo $price; echo "
"; > > 

the result that I am getting is

The result that should be is

One way to do it is to calculate the sum in SQL, as inother answer. If you want to do it in PHP, you can add the cost column to a variable:

$total_cost = 0; while ($row = mysqli_fetch_assoc($result01)) < $total_cost += $row['cost']; >echo "Result: $total_cost"; 

You are calculating the sum for each row. Instead you should try this:

$sql01 = "SELECT * FROM cart where status='1'"; $result01 = mysqli_query($con, $sql01); $cost_array = array(); if (mysqli_num_rows($result01) > 0) < while($row = mysqli_fetch_assoc($result01)) $cost_array[] = $row['cost']; >echo "Result: ".array_sum($cost_array); 

Or (better!) optimize your MySQL query this way:

SELECT sum(cost) finalprice FROM cart where status='1' GROUP BY status 

Now you can access your sum using $row[‘finalprice’] .

It’s easier than your code: In SQL you should use

"Select sum(cost) from cart where status = '1';" 

This is the query for you:

SELECT sum(cost) as price FROM cart WHERE status='1' GROUP BY status 

$sql01 = 'SELECT sum(cost) as price FROM cart WHERE status='1' GROUP BY status' $result01 = mysqli_query($con, $sql01); if (mysqli_num_rows($result01) > 0) < while($row = mysqli_fetch_assoc($result01)) < echo 'sum of cod:' . $row['price'] . '
'; > >

PHP Exercises: Compute the sum of the numbers in a given array except those numbers starting with 5 followed by atleast one 6

PHP Basic Algorithm: Exercise-109 with Solution

Write a PHP program to compute the sum of the numbers in a given array except those numbers starting with 5 followed by atleast one 6. Return 0 if the given array has no integer.

Sample Solution :

 if ($inSection == 0 && $nums[$i] == 6) < if ($flag == 1) < $sum = $sum - 5; $inSection = 1; >$flag = 0; > if ($inSection == 0) < $sum += $nums[$i]; >> return $sum; > echo "Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6:\n". ****, 7, 9, 10, 17] ); echo "\nSum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6:\n". ****, 6, 9, 10, 17] ); echo "\nSum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6:\n". test([5, 6, 7, 9, 10, 17, 1] ); echo "\nSum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6:\n". test([11, 9, 10, 17, 5, 6] ); 

Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 49 Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 37 Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 44 Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 47

PHP Basic Algorithm: Exercise-108 with Solution

Write a PHP program to compute the sum of values in a given array of integers except the number 17. Return 0 if the given array has no integer.

Sample Solution :

 return $sum; > echo "Sum of values in the array of integers except the number 17: ". ****, 7, 9, 10, 17] );

array_sum

array_sum() returns the sum of values in an array.

Parameters

Return Values

Returns the sum of values as an integer or float; 0 if the array is empty.

Examples

Example #1 array_sum() examples

$a = array( 2 , 4 , 6 , 8 );
echo «sum(a) color: #007700″>. array_sum ( $a ) . «\n» ;

$b = array( «a» => 1.2 , «b» => 2.3 , «c» => 3.4 );
echo «sum(b) color: #007700″>. array_sum ( $b ) . «\n» ;
?>

The above example will output:

User Contributed Notes 6 notes

If you want to calculate the sum in multi-dimensional arrays:

function array_multisum (array $arr ): float $sum = array_sum ( $arr );
foreach( $arr as $child ) $sum += is_array ( $child ) ? array_multisum ( $child ) : 0 ;
>
return $sum ;
>
?>

Example:

echo array_multisum ( $data );

Notably the function converts strings to float and ignores strings if they are not convertable:

$a = array( «String» , 2 , 4 , 6 , 8 );
echo «sum(a) keyword»>. array_sum ( $a ) . «\n» ;

$b = array( «12.3456» , 2 , 4 , 6 , 8 );
echo «sum(b) keyword»>. array_sum ( $b ) . «\n» ;
?>

sum(a) = 20
sum(b) = 32.3456

If you have a case where your array has int in strings, it sums them up as if there were only int in the array!
function sum_mix($a)
return array_sum($a);
>
var_dump(sum_mix([9, 3, ‘7’, ‘3’]));
Response will be int(22)

array_sum() doesn’t «ignore strings if they are not convertible», it converts them to zero. array_product() does the same thing, where the difference between «ignoring» and «converting to zero» is much more obvious.

//you can also sum multidimentional arrays like this;

function arraymultisum (array $arr ) $sum = null ;

foreach( $arr as $child ) $sum += is_array ( $child ) ? arraymultisum ( $child ): $child ;
>
return $sum ;
>

echo arraymultisum (array( 1 , 4 , 5 ,[ 1 , 5 , 8 ,[ 4 , 5 , 7 ]]));

array_sum converts strings to integer and array_sum(2,’2′) returns 4.

  PHP program to sum the digits in a number

  To sum the digits in a number, the PHP code is as follows −

  Example

   return $sum; > $my_num = "65"; print_r("The sum of digits is "); echo sum_of_digits($my_num); ?>

  Output

  Above, a function named ‘sum_of_digits’ is defined, that takes an integer as a parameter.

  It first declares the variable sum as 0 and then iterates through the length of the declared integer, and adds the element at the ‘i’th place to the sum. Once the iteration is complete, this function returns the sum as output. Outside the function, the value is declared and the function is called by passing this element as the parameter −

  function sum_of_digits($my_num) < $sum = 0; for ($i = 0; $i < strlen($my_num); $i++)< $sum += $my_num[$i]; >return $sum; >

  How to sum each column on the table PHP

  You need to store each $random so you can total them in the final row.

  $random = rand(1, 8); $results[$i][] = $random; // store $random value in array 

  Then total the array using array_sum()

   $docid = array(1, 2, 3, 4, 5); $table = array('technology' => 1 , 'languange' => 2, 'town' => 3, 'gadget' => 4, 'smartphone' => 5); echo ""; $count = count($table); $doc_count = count($docid); for($i=1; $iDoc.$i"; > foreach($table as $key=>$value) < echo ""; for($i=0; $i<$doc_count;$i++) < $random = rand(1, 8); $results[$i][] = $random; // save in array for totaling echo ""; > > echo ""; for($i=0; $i<$doc_count;$i++) < echo ""; // total array using array_sum() > echo "
  Token/Document
  $key
  $random
  RESULT
  ".array_sum($results[$i])."
  "; 

  you could do something like this

  $sum = 0; for($i=0; $i echo "Total = ". $sum;
