Are there any best practices for efficiently finding the position of a key in a PHP array?

When trying to find the position of a key in a PHP array, one efficient method is to use the array_search() function. This function searches the array for a given value and returns the corresponding key if found. By using array_search(), you can quickly determine the position of a key in an array without having to iterate through each element manually. 

// Sample PHP code to efficiently find the position of a key in an array
$array = ['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4];

$key = 'c';
$position = array_search($key, array_keys($array));

echo "The position of key '$key' in the array is: $position";
