What function can you use to reorganize array index numbers in PHP?

When you remove an element from an array in PHP, the index numbers of the remaining elements do not automatically reorganize. This can lead to gaps in the index numbers, which may cause issues when iterating over the array. To reorganize the index numbers of an array in PHP, you can use the array_values() function. This function returns all the values of an array and reindexes the array numerically starting from zero. 

// Original array
$array = array("a", "b", "c");

// Remove an element from the array
unset($array[1]);

// Reorganize index numbers
$array = array_values($array);

// Output reorganized array
print_r($array);
