What are the differences between str_word_count() and array_count_values() in PHP?

The str_word_count() function in PHP is used to count the number of words in a string, while array_count_values() is used to count the frequency of values in an array. If you need to count the number of words in a string, use str_word_count(). If you need to count the frequency of values in an array, use array_count_values().

// Using str_word_count() to count the number of words in a string
$string = "Hello world";
$wordCount = str_word_count($string);
echo $wordCount;

// Using array_count_values() to count the frequency of values in an array
$array = array("apple", "banana", "apple", "orange", "banana");
$valueFrequency = array_count_values($array);
print_r($valueFrequency);
