What is the significance of using array_keys and the search_value parameter in PHP?
Using array_keys with the search_value parameter in PHP allows you to retrieve all keys from an array that contain a specific value. This is useful when you need to find the keys associated with a particular value in an array. By using array_keys, you can easily identify the keys without having to iterate through the array manually.
// Example usage of array_keys with search_value parameter
$array = ['a' => 1, 'b' => 2, 'c' => 1];
$search_value = 1;
$keys = array_keys($array, $search_value);
print_r($keys); // Output: Array ( [0] => a [1] => c )
