What are the benefits of using predefined functions like count_chars() in PHP for character counting tasks compared to manual methods?

When counting characters in a string in PHP, using predefined functions like count_chars() can simplify the process by providing a built-in solution that is efficient and reliable. These functions are specifically designed for the task at hand, reducing the likelihood of errors and streamlining the code. Manual methods may work, but they often require more lines of code and can be prone to mistakes. 

// Using count_chars() function to count characters in a string
$string = "Hello, World!";
$charCount = count_chars($string, 1);

foreach ($charCount as $char => $count) {
    echo "Character '" . chr($char) . "' appears " . $count . " times." . PHP_EOL;
}
