Are there any best practices for manipulating strings in PHP?

When manipulating strings in PHP, it is important to consider using built-in functions and methods to achieve the desired results efficiently. Some best practices include using functions like `strlen()` to get the length of a string, `str_replace()` to replace occurrences of a substring, and `trim()` to remove whitespace from the beginning and end of a string. 

// Example of manipulating a string in PHP
$string = "Hello, World!";
$length = strlen($string);
$newString = str_replace("Hello", "Hi", $string);
$trimmedString = trim($string);

echo "Original String: " . $string . "<br>";
echo "Length of String: " . $length . "<br>";
echo "Replaced String: " . $newString . "<br>";
echo "Trimmed String: " . $trimmedString;
