All alphabetic characters in an array can be achieved by using chr(), range() with for and foreach loop in PHP. To display the array elements as output we can use echo, print_r() and var_dump() function.
Using range() function: This function is used to create an array of elements of any kind such as integer, alphabets within a given range (from low to high) i.e, the first element of list is considered as low and last one is considered as high. It returns an array of alphabets if the range from A to Z i.e. range(A, Z).
array range( mixed first, mixed second, number steps )
Example 1: Below example illustrate how to display an array of all alphabetic character using range() function.
A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z,
Example 2: Below example illustrate how to display an array of all Alphabetic character using range() function along with array_combine.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z
Using chr() function: The chr() function is used to convert an ASCII value to a character. It accepts an ASCII value as a parameter and returns a string representing a character from the specified ASCII value. The ASCII value can be specified in decimal, octal, or hex values. It returns an array of alphabet if the chr() has its ASCII values from 65 to 91 for alphabet.
string chr( <>int $value )
Example 1: Below example illustrate to display an array of all Alphabetic character using ASCII values.
0 => A, 1 => B, 2 => C, 3 => D, 4 => E, 5 => F, 6 => G, 7 => H, 8 => I, 9 => J, 10 => K, 11 => L, 12 => M, 13 => N, 14 => O, 15 => P, 16 => Q, 17 => R, 18 => S, 19 => T, 20 => U, 21 => V, 22 => W, 23 => X, 24 => Y, 25 => Z,
Example 2: Below example illustrate to display an array of all Alphabetic character using ASCII values with the help of chr() function.
65 => A, 66 => B, 67 => C, 68 => D, 69 => E, 70 => F, 71 => G, 72 => H, 73 => I, 74 => J, 75 => K, 76 => L, 77 => M, 78 => N, 79 => O, 80 => P, 81 => Q, 82 => R, 83 => S, 84 => T, 85 => U, 86 => V, 87 => W, 88 => X, 89 => Y, 90 => Z,
