How can the use of PHP's manual help in understanding and implementing string manipulation functions effectively?

To understand and implement string manipulation functions effectively in PHP, one can refer to the PHP manual which provides detailed explanations, examples, and syntax for each function. By studying the manual, developers can learn how to properly use functions like `strlen()`, `substr()`, `str_replace()`, and more to manipulate strings in their code. 

// Example of using PHP's manual to understand and implement string manipulation functions
$string = "Hello, World!";
$length = strlen($string);
$substring = substr($string, 0, 5);
$newString = str_replace("World", "PHP", $string);

echo "Length of string: " . $length . "\n";
echo "Substring: " . $substring . "\n";
echo "Replaced string: " . $newString;
