PHP Array Exercises : Create a range of specified arrays
59. Create a Range-Like Array from a String
Write a PHP program to create a range like the following array.
Array
(
[20] => 2
[21] => 3
[22] => 4
[23] => 5
[24] => 6
[25] => 7
)
Solution:
PHP Code:
<?php
// Use the array_combine function to create an associative array
// The keys are generated using the range function for values from 20 to 25
// The values are generated using the range function for values from 2 to 7
$result = array_combine(range(20, 25), range(2, 7));
// Print the result using the print_r function
print_r($result);
?>
Sample Output:
Array
(
[20] => 2
[21] => 3
[22] => 4
[23] => 5
[24] => 6
[25] => 7
)
