# 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 41 2 3 4 5``
