What is the method for calling arrays in PHP?

In PHP, you can call arrays using the following methods:

1. Access array elements using square brackets [] and array keys, for example: $array[‘key’].
2. Iterate through each element in the array using a foreach loop, for example: foreach ($array as $value).
3. Use the array_values() function to retrieve all values in an array, for example: $values = array_values($array).
4. You can use the array_keys() function to get all the keys in an array, for example: $keys = array_keys($array).
5. Use the count() function to retrieve the number of elements in an array, for example: $count = count($array).
6. Utilize the in_array() function to check if a certain value exists in an array, for example: if (in_array($value, $array)).
7. Find the key of a specific value in an array using the array_search() function, for example: $key = array_search($value, $array).
