Are there any best practices for handling whitespace manipulation in PHP strings?

When handling whitespace manipulation in PHP strings, it's important to be mindful of leading and trailing spaces that can affect the output of your code. To trim whitespace from a string, you can use the `trim()` function which removes any leading and trailing whitespace characters. Additionally, if you need to remove specific whitespace characters (such as tabs or newlines) from a string, you can use the `str_replace()` function to replace them with an empty string. 

// Example of trimming whitespace from a string
$string = "   Hello, World!   ";
$trimmedString = trim($string);
echo $trimmedString; // Output: "Hello, World!"

// Example of removing specific whitespace characters from a string
$string = "Hello\tWorld\n";
$cleanedString = str_replace(array("\t", "\n"), '', $string);
echo $cleanedString; // Output: "HelloWorld"
