Are there any best practices for manipulating strings in PHP efficiently?

When manipulating strings in PHP, it is important to use built-in functions such as `str_replace`, `substr`, `strlen`, `strpos`, and `implode` to efficiently perform operations like replacing substrings, extracting parts of a string, getting the length of a string, finding the position of a substring, and joining array elements into a string. Avoid using regular expressions for simple string manipulation tasks as they can be slower and less efficient. 

// Example of efficiently manipulating strings in PHP
$string = "Hello, World!";
// Replacing a substring
$newString = str_replace("Hello", "Hi", $string);
// Extracting a part of the string
$substring = substr($string, 0, 5);
// Getting the length of the string
$length = strlen($string);
// Finding the position of a substring
$position = strpos($string, ",");
// Joining array elements into a string
$array = ["apple", "banana", "cherry"];
$joinedString = implode(", ", $array);
