Number Pattern Programs in PHP

This blog explores the world of Number Pattern Programs in PHP! We’ll see how PHP, a programming language, can create cool number patterns like shapes and designs.

Number Pattern Programs in PHP

Using PHP, we can make lots of different patterns using numbers. Some of the patterns are basic number patterns and some are advanced. Let’s discover a few examples of PHP patterns!

Square Number Pattern:

<?php
// Define the number of rows for the pattern
$rows = 5;

// Loop through each row
for ($i = 1; $i <= $rows; $i++) {
    // Loop through each column
    for ($j = 1; $j <= $rows; $j++) {
        // Print the square of the column number
        echo $j * $j . " ";
    }
    // Move to the next line after each row
    echo "\n";
}
?>

Explanation of the code:

This PHP code generates a square number pattern with a specified number of rows. 

1. Define Rows: It sets the variable `$rows` to 5, determining the number of rows for the pattern.

2. Loop Through Rows: It iterates through each row from 1 to the specified number of rows.

3. Loop Through Columns: Within each row iteration, it iterates through each column from 1 to the specified number of rows.

4. Print Square: In each column iteration, it prints the square of the column number followed by a space.

5. Next Line: After completing each row, it moves to the next line using `echo “\n”;`.

Output:

1 4 9 16 25 
1 4 9 16 25 
1 4 9 16 25 
1 4 9 16 25 
1 4 9 16 25

Diamond Number Pattern

<?php
$rows = 4; // Define the number of rows

// Loop to print upper half of the diamond
for ($i = 1; $i <= $rows; $i++) {
    echo str_repeat($i . " ", $i) . "\n";
}

// Loop to print lower half of the diamond
for ($i = $rows - 1; $i >= 1; $i--) {
    echo str_repeat($i . " ", $i) . "\n";
}
?>

Explanation of the code:

This PHP code generates a diamond number pattern with a specified number of rows.

1. Define Rows: It sets the variable `$rows` to 4, determining the number of rows for the diamond.

2. Loop Upper Half: It iterates through each row from 1 to the specified number of rows, printing increasing numbers in each row. The `str_repeat()` function repeats the string `$i . ” “` (which represents the number followed by a space) `$i` times, creating a triangular pattern.

3. Loop Lower Half: It iterates through each row from `$rows – 1` to 1, printing decreasing numbers in each row. Similar to the upper half, the `str_repeat()` function repeats the string `$i . ” “` `$i` times, creating a reversed triangular pattern.

4. Next Line: After completing each row, it moves to the next line using `echo “\n”;`.

Output:

1 
2 2 
3 3 3 
4 4 4 4 
3 3 3 
2 2 
1 

Triangle Number Pattern

<?php
// Define the number of rows for the pattern
$rows = 5;

// Loop through each row
for ($i = 1; $i <= $rows; $i++) {
    // Loop through each column
    for ($j = 1; $j <= $i; $j++) {
        // Print the column number
        echo $j . " ";
    }
    // Move to the next line after each row
    echo "\n";
}
?>

Explanation of the code:
This PHP code generates a triangle number pattern with a specified number of rows.

1. The variable `$rows` is set to 5, determining the number of rows for the triangle.

2. It iterates through each row from 1 to the specified number of rows.

3. Within each row iteration, it iterates through each column from 1 to the current row number.

4. It prints the column number followed by a space.

5. After completing each row, it moves to the next line using `echo “\n”;`.

Output:

1 
1 2 
1 2 3 
1 2 3 4 
1 2 3 4 5

Pascal’s Triangle Number Pattern

<?php
//set the number of rows for the triangle
$rows = 5;

//loop through each row
for($i = 1; $i <= $rows; $i++){
    //initialize the first number in each row as 1
    $num = 1;
    //loop through each column in the row
    for($j = 1; $j <= $i; $j++){
        //print the number
        echo $num . " ";
        //calculate the next number by multiplying the current number by (row number - column number) / column number
        $num = $num * ($i - $j) / $j;
    }
    //move to the next line
    echo "\n";
}
?>

Explanation of the code:
This PHP code generates Pascal’s Triangle, a triangular array of binomial coefficients.

1. Define Rows: Set the variable `$rows` to 5, determining the number of rows for Pascal’s Triangle.

2. Loop Through Rows: Iterate through each row from 1 to the specified number of rows.

3. Initialize Number: Set `$num` to 1, the first number in each row.

4. Loop Through Columns: Within each row iteration, loop through each column from 1 to the current row number.

5. Print Number: Print the current number followed by a space.

6. Calculate Next Number: Update `$num` by multiplying it by `(row number – column number) / column number` to get the next number in the row.

7. Move to Next Line: After completing each row, move to the next line using `echo “\n”;`.

Output:

1 
1 1 
1 2 1 
1 3 3 1 
1 4 6 4 1 

Floyd’s Triangle Number Pattern

<?php
$rows = 5;
$num = 1;
for ($i = 1; $i <= $rows; $i++) {
    for ($j = 1; $j <= $i; $j++) {
        echo $num++ . " ";
    }
    echo "\n";
}
?>

Explanation of the code:
This PHP code generates a pattern known as Floyd’s Triangle. Here’s how it works:

1. Define Rows: The variable `$rows` is set to 5, indicating the number of rows in the triangle.

2. Initialize Number: Another variable `$num` is set to 1, which represents the starting number in the triangle.

3. Outer Loop (Rows): The outer loop iterates through each row from 1 to the specified number of rows.

4. Inner Loop (Columns): Within each row, there’s an inner loop that iterates from 1 to the current row number.

5. Print Numbers: Inside the inner loop, the value of `$num` is printed, followed by a space. `$num` is then incremented.

6. Move to Next Line: After printing all numbers for a row, a newline character (`\n`) is echoed to move to the next line.

Output:

1 
2 3 
4 5 6 
7 8 9 10 
11 12 13 14 15 

Pyramid Number Pattern

<?php
// Define the number of rows for the pattern
$rows = 5;

// Loop through each row
for ($i = 1; $i <= $rows; $i++) {
    // Print spaces to align numbers
    echo str_repeat(" ", $rows - $i);
    // Print numbers in ascending order
    echo implode(" ", range(1, $i));
    // Move to the next line
    echo "\n";
}
?>

Explanation of the code:

This PHP code generates a triangle pattern where each row contains numbers in ascending order. Here’s how it works:

1. Define Rows: The variable `$rows` is set to 5, indicating the number of rows in the triangle.

2. Outer Loop (Rows): The outer loop iterates through each row from 1 to the specified number of rows.

3. Print Spaces: Inside the loop, `str_repeat()` function is used to print spaces to align numbers. The number of spaces decreases as the row number increases.

4. Print Numbers: The `range()` function generates an array of numbers from 1 to the current row number (`$i`). These numbers are then concatenated and printed.

5. Move to Next Line: After printing numbers for a row, a newline character (`\n`) is echoed to move to the next line.

Output:

    1
   1 2
  1 2 3
 1 2 3 4
1 2 3 4 5
