In the case that there's a quantity field, just change the SUM() function to multiply price by quantity: JOIN product AS p ON p.product_id = c.p_id SELECT SUM(p.product_price) AS total FROM cart AS c Assuming you don't have a "quantity" field, the function can be as simple as one SQL query with a JOIN and using the SUM() function.
PHP ARRAY SUM CODE
Your code looks much more complicated than it needs to be. You're overwriting the variable $sql and $row inside the loop that's using those variables for iteration, you're also overwriting the value of $total on each iteration. I'm only getting the latest price not the total price. The product_price in other table which is product. I'm trying to get total price from cart table. $sql = $db->query("SELECT product_price from product WHERE product_id='$product_id'") $no=$sql->rowCount() // number of rows affected by the last SQL statement $sql = $db->query("SELECT * from cart WHERE ip_add='$ip'") By using count() and array_sum() we will find out the average value of the elements of the array.I'm trying to get total price from cart table.
PHP ARRAY SUM HOW TO
We already know how to find out total number of elements present inside array by using count() function. Sum of values = 30 Sum with keys $input=array('One' =>1,'Two'=>2,'Three'=>3,'Fourth') Ħ Average value of all elements of the array Then calling sum will give you the sum of salePrice for elements which match your associative array.
The string part will be ignored and the sum of numbers will be returned. The simplest method by which to do this is to use the sql command. We can apply array_sum() function to an array with both number and string as elements.
The output of the above line would be 9.3 ( the sum of all values inside the array) Here is one example.Įcho "Sum of values = ".array_sum($value2) // Output =9.3 We can store float value in an array and get the sum of Sum of elements of PHP array by using array_sum() and getting average value
usort: Sorting array by using user defined function We can calculate the sum of array elements using the PHP predefined arraysum() function.unset : Deleting elements of an array by using its key or value.Session Array to maintain data in different pages.Breaking of strings to create array using split command The arraysum() function returns the sum of all the values in the array.is_array : To check the variable is array or not.in_array : IN Array to search for elements inside an array.array_map : Using user defined and native function to each element of an array You should then be able to use arraysum() instead of a loop to calculate the total.max Getting the maximum or Minimum value of elements in an array.array_keys : To get array of keys from an array.array_push : Adding element to an Array.array_count_values counting the frequency of values inside an array.Multidimensional array : Creating and displaying.
