What alternative functions can be used to search for specific values in an array in PHP?

When searching for specific values in an array in PHP, besides using the `array_search()` function, you can also use functions like `in_array()` and `array_key_exists()`. These functions provide different ways to check for the existence of a specific value in an array. 

// Using in_array() function to search for a specific value in an array
$array = [1, 2, 3, 4, 5];
$searchValue = 3;

if (in_array($searchValue, $array)) {
    echo "Value found in the array";
} else {
    echo "Value not found in the array";
}

// Using array_key_exists() function to check if a specific key exists in an array
$array = ['a' => 1, 'b' => 2, 'c' => 3];
$searchKey = 'b';

if (array_key_exists($searchKey, $array)) {
    echo "Key found in the array";
} else {
    echo "Key not found in the array";
}
