Using range() function

This range function stores values in an array from A to Z. here, we use two for loops.

Example:

Output:

Using chr() function

Here the chr() function returns the value of the ASCII code. The ASCII value of A, B, C, D, E is 65, 66, 67, 68, 69 respectively. Here, also we use two for loops.

Example:

Php Chrome Desktop

Output:

Using range() function with foreach
