What are the limitations of using "in_array" and "array_search" for searching within arrays in PHP?

The limitations of using "in_array" and "array_search" for searching within arrays in PHP are that they only check the values and not the keys. To overcome this limitation and search for both keys and values in an array, you can use the "array_key_exists" function along with "array_search" to achieve a more comprehensive search. 

// Sample array
$array = array("key1" => "value1", "key2" => "value2", "key3" => "value3");

// Search for a specific key and value in the array
$searchKey = "key2";
$searchValue = "value2";

if(array_key_exists($searchKey, $array) && array_search($searchValue, $array) !== false) {
    echo "Key and value found in the array.";
} else {
    echo "Key and/or value not found in the array.";
}
