PHP Exercises: Check if an array of integers contains a 3 next to a 3 or a 5 next to a 5 or both
116. Contains Adjacent 3's or 5's Check
Write a PHP program to check if an array of integers contains a 3 next to a 3 or a 5 next to a 5 or both.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
{
// Iterate through the elements of the array up to the second-to-last element
for ($i = 0; $i < sizeof($numbers) - 1; $i++) { // Check if there are consecutive occurrences of either 3 and 3 or 5 and 5 if (($numbers[$i] == 3 && $numbers[$i + 1] == 3) || ($numbers[$i] == 5 && $numbers[$i + 1] == 5)) return true; } // Return false if there are no consecutive occurrences of either 3 and 3 or 5 and 5 return false; } // Use 'var_dump' to print the result of calling 'test' with different arrays var_dump(test([5, 5, 5, 5, 5])); var_dump(test([1, 2, 3, 4])); var_dump(test([3, 3, 5, 5, 5, 5])); var_dump(test([1, 5, 5, 7, 8, 10])); ?>
Sample Output:
bool(true) bool(false) bool(true) bool(true)

- Write a PHP script to verify if an array contains at least one pair of adjacent 3's or a pair of adjacent 5's.
- Write a PHP function to scan through an array and return true if two identical numbers (either 3 or 5) appear consecutively.
- Write a PHP program to use a loop to check each pair of adjacent elements for the values 3 or 5, returning a boolean if found.
- Write a PHP script to determine if the array contains consecutive identical pairs of 3’s or 5’s by comparing indices.
Go to:
PREV : Array Contains No 3 or 5 Check.
NEXT : Array Contains Two 5's Next to or Separated by One.
