How can the output of a specific subset of an array be achieved in PHP, considering the limitations of echo() with arrays?
When trying to output a specific subset of an array in PHP using echo(), the entire array will be printed instead of just the subset. To solve this issue, we can use array_slice() function to extract the desired subset of the array and then use implode() to convert it into a string for printing.
<?php
$array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
$subset = array_slice($array, 2, 5); // Extract elements from index 2 to 5
echo implode(', ', $subset); // Output: 3, 4, 5, 6, 7
?>
