PHP loop implements multiplication table (with code)

PHP is a scripting language that has been loved by developers since its birth. With its fast, simple and easy-to-learn characteristics, it has become one of the most widely used languages ​​in web development today. In this article, we will introduce how to use PHP loop to implement the multiplication table.

What is the multiplication table?

The multiplication table is a table usually used to help students memorize multiplication formulas. It has a total of 81 small squares, each square represents a multiplication expression, such as 11, 12, 2*2, etc. We will feel very strange when facing it, but as long as If we study hard, we can quickly remember the relationship between each number and quickly calculate the multiplication results.

PHP loop to implement the multiplication table

Let us introduce step by step how to use PHP loop to implement the multiplication table.

First, we need to understand two PHP functions: for and echo. Among them, for function is used to control the number of loops, and echo is used to output content.

for ($i = 1; $i <= 9; $i++) {
    for ($j = 1; $j <= $i; $j++) {
        echo $j . "*" . $i . "=" . ($j * $i) . " ";
    }
    echo "<br />";
}

The code block shown above uses nested loops. The first loop represents the numbers in each row of the multiplication table, and the second loop represents each number in each row. Print out the results you want. .

If you want to output a more intuitive multiplication table, you can use the newline character "<br />" at the end of each line to indicate a newline. In this way, we can get a complete multiplication table.

Summary

In this article, we learned how to use PHP loops to implement the multiplication table. First, we have an in-depth understanding of the multiplication table, and then use PHP's loop and output functions to implement this function step by step, which is tedious but simple.

Mastering this skill can not only help us better understand the implementation of program loops, but can also be used to solve other similar problems, which has greatly contributed to the computing problems in our daily life and work. convenience.
