What is an associative array PHP?

Associative Array – It refers to an array with strings as an index. Rather than storing element values in a strict linear index order, this stores them in combination with key values. Multiple indices are used to access values in a multidimensional array, which contains one or more arrays.

How do you sum values in an array?

Algorithm

  1. Declare and initialize an array.
  2. The variable sum will be used to calculate the sum of the elements. Initialize it to 0.
  3. Loop through the array and add each element of array to variable sum as sum = sum + arr[i].

How do you sum numbers in PHP?

  3. $sum=0; $rem=0;
  4. for ($i =0; $i<=strlen($num);$i++)
  5. {
  6. $rem=$num%10;
  7. $sum = $sum + $rem;
  8. $num=$num/10;

  3. #Number of elements present in an array can be found using len()
  4. print(“Number of elements present in given array: ” + str(len(arr)));

Which field contains the number of elements in the array?

Java includes a field that contains the length (= number of elements) of the array. With this length field, a Java program can make sure that the programmer cannot use an illegal index.

How do you count the number of elements in an array?

  1. count number of bytes with sizeof() function from whole 2d array (in this case 3*20 = 60 bytes)
  2. count number of bytes with sizeof() function from first array element strs[0] (in this case 20 bytes)
  3. divide whole size with size of one element what will give you number of elements.

What are the advantages of associative arrays in PHP?

Advantages of Associative Array We can save more data, as we can have a string as key to the array element, where we can have associated data to the value to be stored, like in our example, we stored the type of the car as key along with the name of the car as value.
