What is the significance of using array_multisort() in PHP when sorting arrays?

When sorting arrays in PHP, the array_multisort() function is significant because it allows you to sort multiple arrays simultaneously based on one or more sorting criteria. This function is useful when you have multiple arrays that need to be sorted in sync, ensuring that the corresponding elements in each array remain aligned after sorting. 

<?php
// Sample arrays to be sorted
$names = array("John", "Alice", "Bob");
$ages = array(30, 25, 35);

// Sort the names array in ascending order and maintain the alignment with the ages array
array_multisort($names, $ages);

// Output the sorted arrays
print_r($names);
print_r($ages);
?>
