PHP Exercises: Create a new array taking the first two elements from a given array
Write a PHP program to create a new array taking the first two elements from a given array. If the length of the given array is less than 2 then return the give array.
Sample Solution:
PHP Code :
<?php
// Define a function named 'test' that takes an array of numbers as a parameter
function test($numbers)
{
// Check if the size of the array is greater than or equal to 2
if (sizeof($numbers) >= 2)
{
// If true, create a new array $front_nums with the first two elements of $numbers
$front_nums = [$numbers[0], $numbers[1]];
}
// Check if the size of the array is greater than 0 (but less than 2)
else if (sizeof($numbers) > 0)
{
// If true, create a new array $front_nums with the first element of $numbers
$front_nums = [$numbers[0]];
}
// If the array is empty
else
{
// Create an empty array $front_nums
$front_nums = [];
}
// Return the array $front_nums
return $front_nums;
}
// Call the 'test' function with an array [1, 5, 7, 9, 11, 13] and store the result in $result
$result = test([1, 5, 7, 9, 11, 13]);
// Print the new array $front_nums using 'implode' and 'echo'
echo "New array: " . implode(',', $result);
?>
Sample Output:
New array: 1,5
