The quickest way to create an array with a sequence of integers or characters is to use the range() function. It returns an array with values starting with the first integer or character, and ending with the second integer or character. Here is a PHP script on how to use range():
<?php
print("Integers:\n");
$integers = range(1, 20, 3);
print_r($integers);
print("\n");
print("Characters:\n");
$characters = range("X", "c");
print_r($characters);
print("\n");
?>
This script will print:
Integers:
Array
(
[0] => 1
[1] => 4
[2] => 7
[3] => 10
[4] => 13
[5] => 16
[6] => 19
)
Characters:
Array
(
[0] => X
[1] => Y
[2] => Z
[3] => [
[4] => \
[5] => ]
[6] => ^
[7] => _
[8] => `
[9] => a
[10] => b
[11] => c
)
Of course, you can create an array with a sequence of integers or characters using a loop. But range() is much easier and quicker to use.
