What is the best way to delete a specific entry in an array in PHP while maintaining the other keys?

When deleting a specific entry in an array in PHP while maintaining the other keys, you can use the unset() function to remove the element at the specified key. After unsetting the element, you can use array_values() function to reindex the array keys. This way, the other keys will be maintained in their original order. 

// Sample array
$array = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4);

// Delete entry with key 'b'
unset($array['b']);

// Reindex the array keys
$array = array_values($array);

// Output the modified array
print_r($array);
