PHP Program to Print Multiplication Table

A multiplication table is a useful mathematical tool that is used to print the products of a given number with a range of values, generally, it is printed from 1 to 10. In this article, we are going to learn multiple ways to generate and print multiplication tables in PHP.

Formula to Generate Multiplication Table

To create a multiplication table for any number, use the formula:

Answer = Number × Multiplier

Where:
number is the fixed value for which the table is generated.
Multiplier is the range of values (e.g., 1 to 10).

Example 1

• Input: Number = 5
• Output:
  5 x 1 = 5
  5 x 2 = 10
  5 x 3 = 15
  5 x 4 = 20
  5 x 5 = 25
  5 x 6 = 30
  5 x 7 = 35
  5 x 8 = 40
  5 x 9 = 45
  5 x 10 = 50

Example 2

• Input: Number = 3
• Output:
  3 x 1 = 3
  3 x 2 = 6
  3 x 3 = 9
  3 x 4 = 12
  3 x 5 = 15
  3 x 6 = 18
  3 x 7 = 21
  3 x 8 = 24
  3 x 9 = 27
  3 x 10 = 30

Example 3

• Input: Number = 0
• Output:
  0 x 1 = 0
  0 x 2 = 0
  0 x 3 = 0
  0 x 4 = 0
  0 x 5 = 0
  0 x 6 = 0
  0 x 7 = 0
  0 x 8 = 0
  0 x 9 = 0
  0 x 10 = 0

Below are various approaches to generating a multiplication table in PHP, with examples and explanations.

Using a Direct Loop

This is a simple and direct method to print multiplication tables. In this method, we use a simple loop to calculate and display the multiplication table for a given number. It uses a basic iteration working, where the program calculates each multiple of the given number step by step. This approach is suitable for beginners and works efficiently for small ranges such as for generating tables up to 10 or 20.

Steps for Implementation

• Define the number.
• Now, use a loop to iterate through the range (e.g., 1 to 10).
• Multiply the number by the current loop value and print the result.
• Print the Output.

Implementation Code

<?php
// Define the number
$number = 5;

// Print the multiplication table
for ($i = 1; $i <= 10; $i++) {
    $result = $number * $i;
    echo "$number x $i = $result
"; // Using newline for output formatting
}
?>

Output

5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50

Time Complexity: O(1)

Space Complexity: O(1)

Using a Function

In this approach, we use a function to generate a multiplication table. This approach uses a reusable function to generate multiplication tables, which makes it easy to work with different inputs. This is generally useful in larger programs or when the table needs to be calculated for different numbers.

Steps for Implementation

• Define a function that accepts the number as a parameter.
• Now, use a loop inside the function to calculate and print the table.
• Call the function with numbers from 1 to 10.

Implementation Code

<?php

// Function to generate a multiplication table
function printMultiplicationTable($number)
{
    for ($i = 1; $i <= 10; $i++) {
        $result = $number * $i;
        echo "$number x $i = $result
"; // Using newline for output formatting
    }
}

// Call the function with a specific number
$number = 7;
printMultiplicationTable($number);
?>

Output

7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
7 x 4 = 28
7 x 5 = 35
7 x 6 = 42
7 x 7 = 49
7 x 8 = 56
7 x 9 = 63
7 x 10 = 70

Time Complexity: O(1)
Space Complexity: O(1)

Real-World Applications

• Multiplication tables are used to teach basic arithmetic calculations.
• It is used to Automate repetitive arithmetic operations in various scripts.
• It is used to generate reports and charts for web applications.
