The range() function is an inbuilt function in PHP which 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, list’s first element is considered as low and last one is considered as high.

1. Code:

<?php
$arr = range('p','a');
  
echo"Array for range('p','a'): "."<br>";
print_r($arr);
echo"<br>";
$arr1 = range(0,10,2);
  
echo"Array for range(0,10,2): "."<br>";
print_r($arr1);

?>

2. Example:

Input:

$arr = range('p','a');
$arr1 = range(0,10,2);

Output:

Array for range('p','a'):
Array ( [0] => p [1] => o [2] => n [3] => m [4] => l [5] => k [6] => j [7] => i [8] => h [9] => g [10] => f [11] => e [12] => d [13] => c [14] => b [15] => a )
Array for range(0,10,2):
Array ( [0] => 0 [1] => 2 [2] => 4 [3] => 6 [4] => 8 [5] => 10 ) 

3. Syntax:

array range(low, high, step)

Parameters:

1. low: It will be the first value in the array generated by range() function.
2. high: It will be the last value in the array generated by range() function.
3. step: It is used when the increment used in the range and it’s default value is 1.
